Today, induction heating creates quite strong competition with gas and electric boilers. And in the market of heating equipment, induction boilers are positioned as one of the most economical options. If in the industry such boilers began to appear in the distant 80s, then in the 90s they began to be used in domestic purposes.

Basic principles of work

The principle of operation of the induction boiler

Already from the title of induction heating, it can be understood that the basis of the operation of such boilers is the principle of electromagnetic induction. And in order to accurately understand how the system works, it is enough through the coil of thick wire to launch a high current. There will be an electromagnetic field around this device, and quite strong. And if you put in it any ferromagnet - that is, that metal that is attracted, it will warm up - and quickly enough.

So, the simplest example of induction heating, that is, a heat source is a coil, which is wound on a pipe from a dielectric.

Insole, it is necessary to place the core of steel. The coil, which is connected to the source of electricity, will heat the rod of metal. Now it remains to connect the device to the highway, where the heat carrier circulates, and such a primitive induction heating will begin to work with their own hands.

If you briefly describe the principle of operation, then for this you will need only a few judgments. Electrical energy creates an electromagnetic field. The metal core is heated under the influence of electromagnetic waves. Excessive heat from the rod goes to the coolant, heating it.

The coolant in such systems may be not only ordinary water, but also ethylene glycol, and oil. Due to the fact that the fluid heats up intensively, convection flows are obtained. The hot heat carrier goes up, and its relics are already enough to work a small outline. If the highway has a greater length, then the circulation pump is required.

Heating system with induction boiler

Debunk myths

Sometimes in stores selling equipment that exercise induction heating at home can be heard simply unrealistic characteristics assigned to him. And, unfortunately, not always such properties are true. There are several main points that should be known for the truth:

• Novelty of principle. Many argue that these are innovative technologies that are based on the principles of physics. In reality, this is the case: the phenomenon of electromagnetic induction was opened by Michael Faraday in 1831. And since the twentieth century, the induction system of heating was used in the industry to melted steel. As you can see, this is not a new technology, but only a well-known principle that has been used in modern times in domestic purposes.

Water heating in induction boiler

• Efficiency. Frequent assertion is that the induction heater for heating uses 20-30% less energy than other electrical analogs. In reality, everything is like this: any heating device is all 100 percent of the energy that it uses, turns into thermal - of course if it does not make mechanical work. The efficiency can be less. It all depends on how heat dissipates around the heating device. The time for which the heat carrier will heat up to the desired temperature, directly depends on how effective the operation of the heating element is. Therefore, high speeches about revolutionary economy is just a trick. After all, no one has canceled the law of energy conservation. To get 1 kW heat, you need to spend at least 1 kW of electricity. In addition, some part of the heat will be spent just like that. For example, the coil itself is heating, since the resistance of the conductor is not zero.

Effect of using induction boiler

• Durability. Another frequent statement is that the heating of the induction slab will work with you at least 25 years, and that this is the most durable version of the heating with electricity. Mechanical wear of boilers is impossible, since they do not have mobile elements. The copper winding has a great margin of strength, and if you use it with proper cooling, it will serve for a long time. The core in any case will gradually collapse - as aggressive impurities can affect it, and the constant heating-cooling will not give strength. But we note that even this process is very long. In the control scheme - several transistors. They will be the defining life of the entire equipment without fail. It is usually a warranty for 10 years. Although there are cases when the equipment worked and 30 years. The conclusion from this total is as follows: induction water heaters for heating will work much longer than the analogues of the Ten.
• Indispensable properties. Many say that induction boilers retain their original characteristics for decades due to the fact that it does not appear. First of all, let's say that the effect of scale is slightly exaggerated. The layer of lime does not have high heat insulating properties, and in a closed system a lot of deposits will not appear. But this cannot be said about the core - here it is a frequent phenomenon. So, the heating with the help of the induction plate is really not subject to scale.
• Silent work. In fact, if you study the reviews, it can be said that any electrical equipment will not make noise when water heated, as there are no acoustic oscillations. Noise may appear only from pumps. So judgment is true.
• Compactness. Induction equipment can be installed in any room. This statement is true: This device is a segment of a pipe that does not require a special place.

Induction boiler

• Induction heating of water for heating is safe. If the heat carrier leakage happens, the electromagnetic field will not disappear automatically. The core will continue to heat up if it does not stop the power supply, then the housing and the fastening will be broken through seconds. That is why when installing, an automatic shutdown of the induction boiler should be provided in such situations.

The solar water heater is a water heating system using solar energy. This type of collector is a heat exchanger that converts solar energy into thermal. This method of energy accumulation allows you to get hot water with minimal costs of financial resources.

If we consider the device of this equipment, then its main part is directly the collector. This part of the water heater is a kind of radiator, which consists of a system of thin tubes. It occurs on the circulation of the coolant, in this case of water, and the absorption of solar energy.

Also isolated the reservoir in which water is located. This peculiar storage performs the function of the expansion tank, and with some embodiments, the role of the heat exchanger is also.

Standard version of the water heater function:

1. From the accumulative tank through the natural force of gravity, the coolant goes into the lower part of the collector.
2. During heating, water, gradually on special tubes will rise up, and the free part is again filled with the coolant.
3. After the water has passed the collector, it again fills the receiving tank. We get a closed cycle.
4. The heated water from the tank is supplied to the consumer through the heating and water supply system or again goes into the heat exchanger.

This is a classic and simplified work scheme that can be complicated depending on the type of heater.

Types of solar water heaters and their characteristics

Allocate several principal classifications:

By type of circulation

1. Natural - In this case, the circulation flows due to the physical properties of water. The heated fluid is known to have a smaller density, but increases in volume. Based on this, it takes place on the tubes to the very top. A new portion of water comes to the liberated place.
2. Forced - In order to occur natural circulation, the tank must be placed above the collector. But this installation scheme is not always appropriate, and it can be implemented, especially if the reservoir of a large volume.

In the case of a solar water heater, with natural circulation, the collector is placed on the roof of the roof and immediately install the tank. If the latter has a large volume, then such a roof load can become critical. The solution will be the placement of the reservoir in the basement part of the building, then in this case the forced circulation of special pumps are used.

With this method of circulation, oils can be used as a coolant. They are practically no ability to natural circulation, but with the function of the coolant copes excellent.

By type collector

1. Panel - The simplest performance. The collector tubes are coated with black paint and installed in a panel body, which is closed with glass or transparent plastic. Although the design is very simple, but the effectiveness is also small, since the coolant loses part of the heat, while in the collector. The loss of accumulated heat can be significant, because the design of the collector is identical to the radiator. This type of solar collector is suitable for the terrain, where solar illumination is regular or the obtained fitting water will be used as auxiliary.
2. Vacuum - In the tube there is a coolant. The very same tube is placed inside the vacuum flask, which is capable of passing the solar heat.

Such a design almost completely eliminates the loss of heat, while the aqueous coolant is heated to the boiling point, and the oil is up to 200-300 degrees, which makes it possible to use the resulting heat for the heating of the building. It is natural that such a collector is more expensive than panel, but the result obtained will justify the costs.

By type circuit circuit

1. Open - It is used to provide hot water of the dwelling. The heat carrier in this case acts water that is used for various household needs and, accordingly, it does not fall back to the contour.
2. System with one contour - Used for home heating. The coolant heated in this way is used as an additive to the coolant, which heated the traditional method. In this case, the heated coolant goes into the heating system, after which is again transferred to the receiving tank and to the collector.
3. Double-circuit heating system - The most universal. It is possible to use such for heating in winter or for water supply.

You can also choose one of the possible coolants - water, oil or antifreeze. After the collector, the coolant passes the heat exchanger, in which heat transfer takes place on the second circuit. The second coolant used is already on its intended purpose - for heating or water supply.

What can I use?

With the help of such water heaters, it is possible to solve the question not only about the regular hot water supply, but also to provide a warm house.

Water heaters will help solve such tasks:

1. Ensuring all year round hot water.
2. Maintaining the heating system.
3. Heated water for pools.
4. Water heating for various industrial and agricultural needs.

Installation

Since the equipment runs from solar energy, then, accordingly, the installation of the heater will be carried out outdoors. Installation is recommended on the roofs of buildings, on balconies or other architectural protrusions.

The water heater screen should be directed south. The installation is carried out at a certain angle to the horizon, which is equivalent to geographic latitude of the area.

The water heater constantly absorbs energy and for obvious reasons the source of energy cannot be turned off, therefore, in the case of low water consumption, the stagnation temperature can reach up to 300 ° C.

For this reason, the use of plastic and steel pipes with zinc coating is not allowed. Optimal in operation will be pipelines made of copper or stainless steel.

The hot contour of the solar water heater must have thermal insulation, it will avoid burns and fires. The temperature mode of the equipment when choosing heat insulation and fasteners should be taken into account.

Manufacturers of solar water heaters on the housing of their products indicate the exact temperature of stagnation.
The collector panels must be in the open space so that there is open access to sunlight. It is necessary to eliminate the presence of possible obstacles.

Most often, the angle of inclination of the collector will be the slope of the roof slide. In order for the efficiency of the water heater, closer to the maximum, it is better to adhere to the recommendations and use a special rack that the collector will be attached.

Those. The key to the correct and efficient operation of the equipment is only a few rules:

• south direction;
• the correct angle of inclination;
• unhindered access to sunlight;

Incorrect installation will reduce the quality of the water heater, and the invested funds will not be justified. The type of heater can also play a role in the method of its installation. When installing, take into account the type of equipment used.

Distinguish such systems:

Passive

It implies leakage absorption and accumulation of energy. Solar energy falls on the heating object without controlling this process, i.e. There are no mechanisms and controlling elements. This is a simple system that does not require special costs. However, the disadvantages are that the water heater works unevenly and not at full capacity.

The most visual example is a darkened tank, which is placed over the summer shower. In such passive mode, one-connecting systems operate in which the process of natural circulation is applied. For the full operation of the system, the receiving tank is placed above the collector, but this installation method is not always convenient. You can solve the question using another method of system operation.

Active

Lack of disadvantages of the passive system. Its functioning is based on the fact that the sun rays thanks to special devices are moving to heat energy, which is systematically transmitted to the heating Baku and the consumer. The functioning of such a heater is achieved due to forced circulation, which can be maintained in single and two-circuit systems. Also used and additionally install engines that rotate panels and pumps, measuring equipment, as well as devices for monitoring and managing the operation of the system.

Overview of solar water heaters on the market: manufacturers and models

Widespread use in the practice of such water heaters is observed in many European countries: Israel, Turkey, Saudi Arabia, China, etc. Since the spread of this type of products is actively increasing, then the number of companies that are engaged in the manufacture of solar water heaters and provide services for their installation and maintenance.

Below is a list of top manufacturers who have entered the world market:

1. Sunrain Solar Energy Co., Ltd. - China, has a full cycle of production of this equipment and their components.
2. Viessmann. - Germany, produces two models of heaters: Vitosol 200 and Vitosol 300. The difference consists in the different structure of the heating node.
3. Buderus. - Germany. The model range is represented by three possible versions - SKR6, SKR12, SKR21.
4. ARISTON. - Italy. The Kairos VT vacuum collector model is available on two types - on 15 or 20 tubes.
5. Ferroli. - Italy. Ecotube collector is represented in one model.
6. Vaillant.- Germany. The models of their production are produced by 6 or 12 tubes, which can be formed into blocks to increase productivity.

By purchasing products of manufacturers with worldwide name, you can be confident as a product and guarantees that are given to the equipment itself and its further maintenance. The price, respectively, will also be at the level.

In any case, when choosing a solar water heater, you must pay attention to such technical parameters:

• optical efficiency;
• thermal loss coefficients;
• collector's area;

With these indicators, it is possible to estimate the energy efficiency of the water heater. If there is no such information, it is impossible to appreciate the operation of the acquired equipment and all pitfalls will be detected directly during operation and after certain investments that may simply be unjustified.

Price overview

In addition to the world name, the cost of the heater can affect:

• build quality;
• the material of the absorber and the case;
• thickness and option laying isolation;
• glass thickness, etc.;

Since, constructive differences that can affect the cost of equipment a lot, then prices fluctuate in a large range. For example, the Russian production collector will cost within 21 thousand rubles. (Falcon-effect), vacuum collector 30HP - $ 795 (TM "Atmosfera" China), VFK 150V water heater - 690 euros (Vaillant, Germany), Solar 7000TF - 875 Euro (Bosch, Germany).

German manufacturers in the kit include original fasteners, which are often made of stainless steel or aluminum, and it also affects the price. The final cost will include payment for installation work, buying the necessary consumables and auxiliary materials.

The modern and most economical water heating device is an induction water heater. Unlike analogues, it is completely environmentally friendly, not dried and does not burn out air, meets modern safety requirements. It can be used both as a flow water heater, and to play the role of a boiler for the heating of the room. The device is usually bought in the store, we offer an alternative - independent manufacture. In the latter case, the device may not have such an attractive appearance, but it will cost much cheaper.

Pros and disadvantages of induction devices for water heating

The device has a fairly simple design and does not require special documents allowing the use and installation. Induction water heater has a high degree of efficiency and optimal reliability for the user. When using it as a boiler for heating, you can not even install the pump, since water flows through pipes due to convection (with heating, the liquid is practically turning into pairs).

The device also has a number of advantages, which distinguishes it among other types of water heaters. So, induction heater:

In induction heaters, water becomes hot due to the pipe on which flows, and the latter is heated due to the induction current created by the coil.

• much cheaper than their analogues, such a device can be easily assembled independently;
• completely silent (although the coil and vibrates when working, but this vibration is not tangible for a person);
• during operation, vibrates, thanks to which dirt and scale does not stick to its walls, therefore it does not need cleaning;
• it has a heat generator, which can be easily sealed by the principle of operation: The coolant is inside the heating element and the energy is transmitted to the heater by means of an electromagnetic field, no contacts needed; Therefore, they will not need sealing gum, glazes and other elements that can quickly spoil or leak;
• it is easy to break in the heat generator, as the water heats the ordinary pipe, which is unable to spoil or blown, unlike the Tan;

Do not forget that the induction heater service will be much cheaper than the boiler or gas boiler. The device has a minimum of parts that almost never fail.

Despite the huge amount of advantages, the induction water heater has a number of flaws:

• the first and most painful for the owners is an electricity account; The device cannot be called economical, so you have to post a certain amount of time for its use;
• the second - the device is very hot and heated not only itself, but also the surrounding space, therefore it is better not to touch the housing of the heat generator during its operation;
• the third - the device has extremely high efficiency and heat transfer, so when used be sure to install the temperature sensor, otherwise the system may explode.

Induction water heater with your own hands: Scheme

The device is a transformer having two windings: primary and secondary. The first circuit converts electrical energy into vortex currents, thereby creating an induction field of aimed action, which provides induction heating. On the secondary circuit, the transformed energy is transmitted to the coolant (in our case it is water).

It is important to consider the type of material from which the winding is made. So, in household models, the copper wire is most often used. Such material is well suitable for water heating in boilers.

In addition to the transformer in the device there is a generator and pump (optional).

Scheme of a simple induction water heater. As can be seen, the device has a fairly simple design and a small number of elements.

Heat generator nodes and parts

The device includes:

• aC generator that increases current frequency;
• inductor transforming electricity to magnetic energy is a coil of copper wire;
• the heating element, most often its role plays a metal tube.

Thanks to this design, energy transmission is carried out practically without loss. CPD reaches 98%.

Principle of operation

Induction water heater consists of a generator, coil and core, the latter is heated due to electromagnetic energy

The device converts electrical energy into electromagnetic. The latter, in turn, affects the core (tube), which heats up and transmits heat energy. Converts all these energies inductor consisting of a coil and core. The generator is used to increase the current frequency, since with a standard frequency of 50 Hz, it is difficult to achieve high heating.

In factory models, the frequency of the current reaches 1 kHz.

Flowing induction water heater with your own hands

Before starting to install, you need to stock it with the necessary details. So, the best option will be a welding high-frequency inverter, smoothly changing current strength range. Such a device will cost the cheapest. A more expensive option will be a three-phase transformer, which is a source of AC power for the water heater inductor. In this case, it is worth using a coil at 50-90 turns, and to take copper wire with a diameter of 3 or more millimeters as a material.

As a core, you can use both metal and the polymer pipe together with the wire (used as a heating element). In the latter case, the wall thickness should not be less than 3 mm in order to quietly withstand high temperatures.

To build a water heater, you will need: nippers, screwdrivers, soldering iron and welding machine, if a metal pipe is used.

Installation of induction water heater

Cut the pipe with copper wire by making about 90 turns.

The options for assembling the device There are many. We suggest try collecting the device according to the following scheme:

1. Prepare workplace, materials and tools.
2. Fix a small segment of the polymer pipe (do not forget that the minimum wall thickness should be 3 mm).
3. Cut the core ends to remain 10 cm in the reserve of the wires for the taps.
4. At the bottom weapon, mount the corner. In the future, it should be connected here to the reverse of heating (if the heater is used as a boiler).
5. Tightly lay a chopped wire around the pipe. It is necessary to make at least 90 turns.
6. Install the tee on the top nozzle through which hot water will be out.
7. Mount the protective circuit of the device. It can be made of both polymer and metal.
8. Connect copper wire to the water heater terminals, then fill the core with water.
9. Check the performance of the inductor.

Recommendations. In all the conclusions, it is better to install ball valves for the convenience and simplicity of dismantling the water heater in the event of a breakdown. But the pipe is not necessary to fill with metal pieces, since it does not give proper effect. Do not forget to leave the window in the housing to access the welding machine control panel.

Induction water heaters for heating

The heating circuit, where an induction boiler is used as a heat carrier heater.

Such a device has a good proven itself not only as a flow water heater, but also a boiler for heating. True, in this case, the welding machine in the role of the generator is no longer suitable, have to use a transformer having two windings. The latter transforms the vortex currents arising on the primary winding into the electromagnetic field, which is created on the secondary circuit.

In the heating system, the heat carrier may be not only water, but also oil or antifreeze. That is, any liquid capable of conducting an electric current.

The boiler from the induction water heater should be equipped with two nozzles for hot and cold water. Cold water will come from the bottom, it must be mounted on the introductory line of the line, and on top it is necessary to position the nozzle that will serve hot water into the heating system. As a result, the circulation of water is carried out naturally under the action of convection without a pump.

What you need to know about security

Do not forget that we are dealing with a source of increased danger - an electric heating device, so when it is assembled and used, some rules must be followed:

Be sure to use a separate electrical line to connect the induction boiler, as well as equip it with a security group.

1. If the water circulation is carried out in a natural way in the boiler, then be sure to equip it with a temperature sensor so that the device is automatically disconnected during overheating.
2. Do not connect the homemade water heater into the socket, it is better to make a separate line with an enlarged cable cross section for this.
3. All open sections of the wires need to be insulated to secure people from shock or burn.
4. In no case do not turn on the inductor if the pipe is not filled with water. Otherwise, the pipe is melted, and the device is closed or it can also light up.
5. The device must be installed at an altitude of 80 cm from the floor, but so that about 30 cm remains to the ceiling, it is also not worth installing it in the residential area, since the electromagnetic field does not affect the health of people.
6. Do not forget to make the inductor grounding.
7. Be sure to connect the device through the machine to the latter in the event of an accident disabled the power from the water heater.
8. A safety valve will be built into the pipeline system, which will reduce the pressure in the system automatically.

Conclusion

The induction water heater has a high efficiency, can act as a boiler for the heating system, also an independent assembly and installation is also allowed, and its use is not regulated by the Law of the Russian Federation. But still before using it, it is worth weighing everything for and against. Despite its high efficiency, the device consumes a large amount of energy, it is considered unsafe (especially homemade) and poorly affects human health. Therefore, we recommend installing the inductor in a private house or in the country.

The electric water heater of the accumulative type, or, in a simple, boiler, has long and firmly entered our life, providing additional comfort and allowing not to depend on the utility systems of hot water supply. This simple device in automatic mode supports the necessary water temperature, while having its definite reserve. The instruments manufactured by industry have a variety of shape, sizes and external design. Despite the seeming differences, at its base, all water heaters have a similar design and a single principle of operation. However, making the choice between a model of the boiler, it should not only understand how it is arranged, but also to understand the features of the execution of some of its components.

In fact, any water heater of this type is a large thermos having an inside tubular electric heater (TEN), so the design of all boilers has such items:

• external case with details allowing you to secure the device on the wall or floor;
• inner tank;
• heat-insulating layer between the inner capacity and the case;
• tubular electric heater;
• thermostat with the possibility of adjusting the heating temperature;
• safety valve;
• protective magnesium anode;
• control and indication scheme.

When choosing a boiler, it is impossible not to notice a big difference in price even between different models of one manufacturer. It is primarily due to the technology and material of the manufacture of the indoor tank, as well as the presence of an electronic control unit and indication.

These parameters set the convenience of using the device as well as the duration of its service.

Housing

Water heater housings have both strictly cylindrical and oval and even rectangular shape, a variety of coloring and design design. Often on the outside of the casing, the thermometer is mounted for monitoring the operation of the device, as well as regulators or control elements. The material of the manufacture of housings is steel sheet or plastic.

To install the boiler, in the design of the housing there are fasteners, depending on the type of placement (wall or outdoor installation scheme). The space between the water heater housing and the inner tank is filled with thermal insulation material - most often in its role is dense polyurethane.

Inner Buck

The design of the inner container of the boiler must comply with the criterion of increased corrosion resistance and at the same time to withstand constant temperature differences, so the manufacturers pay a lot of attention to this element, developing new tank coatings and applying methods for its protection.

Steel coated pots from glass email or glass foam

Such a coating is obtained by spraying the protective layer, followed by its firing at high temperature (up to 850 ° C). The glass is not capable of oxidation, so absolutely not corrodes. In addition, her smooth surface opposes the formation of scale.

Paradoxically, but the main disadvantage of such a coating stems from its dignity - the high hardness of the layer is low and over time, the constant water temperature drops lead to the formation of microcracks in its layer, which in the end contribute to the destruction of the tank.

Manufacturers are constantly looking for new compositions for covers of this type. For example, the addition of titanium powder equalized the temperature coefficients of the expansion of glass fluorofore and steel, slightly improving the resistance of the layer to cracking. A little to reduce the harmful effect of temperature effects, by setting the water temperature in the boiler not higher than 70 ° C, although still at least once a month will have to warm up the device as possible to comply with sanitary rules. An increased weight of the boiler can be considered another disadvantage of the glass fluorforum coating of the tank. Companies producing water heaters with tanks of this type provide a guarantee for their products not more than 3 years.

Steel tanks with titanium spraying

Spraying titanium powder on the inside of the tank is achieved excellent corrosion resistance. In this case, this type of coating has high strength and mechanical resistance, having weak points only on welding joints. A guarantee for a device with such a tank is up to 10 years, which is a huge advantage, even if it takes into account its fairly high cost.

Stainless inner tanks

Such capacities are deprived of the disadvantages of the two previous elements. Stainless steel, like titanium, is able to withstand the influence of impurities in water, as well as corrosion. It is believed that stainless steel gives water a peculiar smell and taste appearing during its heating, but these are only speculation, absolutely not confirmed by scientific research. It is known that "stainless steel" does not enter the chemical reaction with water. Manufacturers also give up to 10 years warranty, but they are the most expensive. Stainless steel tanks, as well as with titanium spraying, are more susceptible to the formation of scale, rather than glass refractory, but it does not diminish their advantages. In the inner tank, the cutting tubes of cold water and removal of hot, as well as an electronic heating unit and protection.

Heating and protection unit

Elements that are responsible for heating water to a certain temperature, as well as protective from the destruction of the inner tank metal, are installed on a metal flange, connected by a seal to the inner tank of the device.

Water heating uses in various power. Depending on the heating principle, distinguish:

• "Wet" tans, which are directly in contact with water, so inevitably covered with a scale, which must be removed periodically, otherwise due to overheating, the TEN fails;
• heaters "dry" type. It is devoid of this disadvantage, since installed in a metal tube, which also makes contact with the liquid. Such a scheme allows you to get rid of the scale not only on the heater, but also on the tube coated with a layer of glass fluorofore.

Some boilers are equipped with several heaters. This design allows stepped heating adjustment, and also reduces the number of inclusion cycles for each of them (voltage jumps during the inclusion of instruments affect their durability).

Together with the Tanes on the flange there is a thermostat and a magnesium rod (anode). The thermostat is responsible for the inclusion of the heating element while reducing the water temperature below the consumer installed. The thermoregulators are used both mechanical type and electronic devices working together with the electronic control unit. Often, the thermostat device includes a protective shutdown scheme in the absence of water in the tank. The magnesium electrode is designed to reduce the exchange of metal components inside the boiler, giving up its particles. Such a scheme reduces the effect of flushing electrons from structural elements and they are corroded to a significantly lower. The magnesium rod itself is quite quickly destroyed and requires periodic replacement (when thinning to 10 mm or a decrease in length to 200mm). The control and indication scheme provides additional amenities when using a water heater, having functions of precise water temperature adjustment, inclusion of heating in time, maintaining varying degrees of heating depending on the time of day.

Principle of operation of accumulative water heaters

The scheme of operation of the boilers is built on the principle of separation of water layers with different temperatures. As you know, warm layers of fluid are at the top. Their selection from the water heater is carried out through the hot water removal tube, the length of which allows the upper, the most warm layer. Cold water, on the contrary, enters the lower part of the tank, where water heaters are installed. In addition, a divider is installed on a short supply tube that does not allow fluid to flow and thereby contribute to the mixing of warm and cold water.

The peculiarity of the warm liquid rise up will not allow the use of a boiler of the vertical design, placing it parallel to the ground. It is worth paying close attention to it, choosing the type of device under your needs.

Heating of cold water is carried out by a TEN (one or more). It monitors the thermostat. When the predetermined temperature is reached, it opens the heater power supply circuit.

Good thermal insulation allows you to maintain the desired water temperature, spending the minimum of energy on its constant heating.

In the case of using multiple heaters, one TEN is used to maintain temperature at a specified level. The remaining is included at a strong flow rate, repeatedly increasing the power of heating. Such a scheme increases the efficiency and reliability of the device.

The warm water selected from above is constantly replaced by a newly heated liquid, which is supplied from the highway. So the process of continuous heating is arranged. With a large consumption, the water temperature at the outlet of the boiler falls over time, so it is necessary to choose the volume of the drive, based on the size of the hot water treatment.

A thermostat malfunction is possible, while water can boil, as a result of which the pressure in the inner tank increases to a dangerous level. To prevent an accident, a safety valve is installed on the cold water supply tube - when the limit pressure is reached, it opens, thereby throwing out part of the fluid into the feeding line. The same valve is used to drain water from the device during preventive work.

A detailed video on the boiler device is presented below:

It is not necessary to neglect the conduct of periodic preventive measures consisting in cleaning the boiler from scale and rust. They will allow the device to work reliably and efficiently, and also will be removed from unplanned spending.

Have problems with hot water? The situation will save the nozzle for the water heating - a device embedded in the kitchen or bathroom faucet and providing residents of a country house or an apartment with water with the required temperature. The compact water heater on the tap is recommended for use in cottages, which are located far from the central network of water supply. You do not need to purchase a single nozzle and the crane. In specialized stores of plumbing can already buy a flow mixer with a water heater for a kitchen or a bathroom. It is suitable for apartment buildings.

It is advantageous to install it in apartments, where for the summer period is disconnected by hot water or its temperature in the system does not correspond to the regulatory indicators. In such cases, contemporaries usually install the water heater, but the nozzle to the crane, which can be used in fact in any plumbing store, will cost 7 times cheaper. Recalls the mixer with the heater and in emergency situations. The scope of application of plumbing equipment is extensive. You can install a crane for hot water, the price of which can vary in the range from 2,900 to 5,200 rubles, in:

• beauty salons and entertainment centers;
• medical institutions;
• cotton houses;
• careci sphere institutions and so on.

Mixer installed in the house or apartment with a flow water heater will work from the mains. Heated substance takes 5-7 seconds since the opening of the crane. Depending on the model and manufacturer, the nozzle for a water heating of water can heat the substance to 60-800c. Each type of mixer provides fluid temperature adjustment. Therefore, the device for heating water to the crane can be used in apartments and homes where small children grow. Tests have shown that the plumbing equipment of this class is as securely as possible and safely. This is how the Chinese manufacturer's device for a washbasin looks like.

Advantages of portable heaters

• Universality.

In most cases, electric tap for water, the price of which depends on the manufacturer, buy for country houses. Users consider in this case the installation of such a device is a profitable solution. In other cases, electric taps are considered to be excesses. This opinion is not entirely true. A portable water heater electric faucet is profitable and when intermittent / disconnected in a hot water apartment. It can be installed on the "Problem", then dismantle and connect the usual mixer.

An electric crane that warms the water itself, the price has access to and is installed in a horizontal way. The principle and technology of installation is similar to the classic mixer. The only nuance of the installation is the water heater on the faucet in the bathroom or the kitchen is connected only to the pipe of cold water and in addition to the network. The installation is performed on the sink or sink sink, baths in the provided holes. Portable electrical nozzle for water heating can be installed without the help of a plumbing.

• Available cost.

Buying a boiler, its installation and maintenance will cost an order of magnitude more expensive than the nozzle for the faucet for heating water, the price of which will pay, if you believe to report users, after 6-8 months.

• Fast and uniform fluid heating.

Hot liquid from the mixer will flush after 5 seconds after turning on the crane. In this regard, the water heating mixer, the price of which is an order of magnitude lower than the cost of the boiler, is a more practical device.

• Saving time.

Heated water on the stove or with a boiler will take from 40 minutes to 1.5-2 hours. In order not to spend time, it is more profitable to buy a water heater for a bathroom or kitchen, which will serve a hot liquid of a given constant temperature during the entire period of operation of the device. Based on this, many consumers consider the device to heal water to the crane most practical option - the hot liquid does not finish at an inappropriate moment, there is no need to perform heating again.

• Saving funds.

When the fluid is heated on the plate or with the help of boiler, consumers spend gas / electricity for a long time. At the same time, the boiler warms the liquid every 15-25 minutes. And the electric water heater on the tap in the bathroom, which can be with a guarantee to 3-5 years, functioning in fact. When a hot liquid is needed, then the user gets it. The rest of the time the nozzle for heating water to the crane, the price of which depends on the type of mixer does not consume electricity. A portable mixer with an electric water heater consumes 3 kW per hour of electricity.

• Compact dimensions.

Due to the design features, the faucet is a water heater, which can be used in several reliable Chinese manufacturers, has an enlarged case. Dimensions determines the nozzle for the warming of water to be heated, which can be used separately from the mixer (if the repair is required). But whatever the magnitude did not have a water heater or nozzle for a crane, and the dimensions of the plumbing electrical device will be much less than the boiler. Like the localization area. An innovative electrical faucet for the kitchen or bath takes as much space on the washing or sink, the side of the plumbing, as well as typical.

• Water consumption savings.

A compact portable water crane is always complemented by a special nozzle for saving fluid flow. It is a aerator that warns the splashing of the substance. Using the water heater flowing electric to the crane, consumers can complement the mixer and a special aerator that enhances the jet, reducing the volume of the subservation subservation. Modern water heater faucet has water consumption from 6-8 liters per minute.

• High decorative qualities.

Many users believe that the nozzle for the water heating is spoils the appearance of the plumbing device and makes it typical design. This opinion is mistaken. In some manufacturers, you can purchase a mini-water heater flowing to a crane with a unique color solution. At the same time, the style of the mixer itself may be different. According to designers, the water heater flowing to the crane not only does not spoil the appearance of the device, but also makes it unusual, unique. In the market, you can buy an electric mixer for hot water with different color of the case - red, granite, gray, milky white, yellow, frosiness and so on. In the leading manufacturers, you can buy a heater for a tap for water with a unique form of extinguishing, levers or valves of non-standard geometry.

An innovative water heating mixer has another advantage - it is safe. The device is grounded, it is supplied with control mechanisms that are not heated during the operation of the water heater for the crane, and the lever for adjusting the temperature of the water.

Features of the design and principle of operation

The principle of functioning of the device is extremely simple. As mentioned above, the water heater electrical flowing to the crane is connected only to the pipe of cold water. When the mixer is turned on, the liquid is fed to a special reservoir, which is placed in a TEN. Within 3-5 seconds, the substance is heated and entered into the evidence. In order for the electrical mixer to safely perform its functions, it is supplied with the following components:

• Case. It contains a water heater for a crane, the price of which depends on the operational characteristics of this item, and electronic nodes. The housing can be performed from thermoplastic or metal. In 87% of cases, the water heater nozzle to the mixer is sewn into a heat-resistant body. This ensures the safety of the operation of the device.
• Spin. Form and dimensions depend on the type of water for water supply. If you need a water heater for a tap in the bathroom, the price of which will depend on the external data, then the emission will be shortened, like typical mixers. Kitchen variants of devices are equipped with high and arcuate poles. A fixture can be installed to heat the water to the bath in the bath. There are beautiful models of plumbing equipment equipped with a hygienic shower. In this class of devices, you can buy a water heater for a crane with a shower and a long / shortened spout. A variant of sanitary devices set.
• Control lever. This element of the water heater crane is installed only in three positions. If the user needs to turn on cold water, you need to turn the right lever. If it is necessary that the water heater on the crane starts to function, the left element should be rotated. If the lever is put straight, then the mixer will stop functioning. In any way otherwise, turn the lever of the mixer with a water heater can not, which guarantees the safe use of the device - the incorrect use of the spout and burn is excluded (the liquid is not warmed instantly).
• Flexible eyeliner.
• Ceramic cartridge.
• Thermocouple and pressure valve.
• Performance indicator in heating mode.

Since the water heater in the mixer is an electrical device, it must be isolated from contact with flowing water. For these purposes, waterproof protective membranes are used in high-quality cranes. They are isolated electrical nodes. In addition, the electric faucet for hot water has a Uzo - a device that automatically turns off the TEN if there are failures in the power grid. Uzo warns the occurrence of accidents (user shocks) and protects the heater of hot water to the crane from the brave.

The pressure valve used in the mixer design also performs a protective function. If the nozzle works to heat the water to the mixer and the water pressure in the pipes at this moment drops to 0.4 atm. Or the substance ceases to succumb, the TEN will automatically turn off. Automation and for water pressure in 7 atm. Disable the flowing water heater on the crane, which can be used for kitchen equipment in the house where small children grow.

In order for the mixer flowing water heater, due to the hydrowarder, a silicone damper is provided in the design. It is also worth remembering that the nozzle for a crane for hot water does not heat the liquid above the set norm, so the burns are excluded. In stores consumers can buy a device capable of heating the substance strictly to a temperature of 60 and 700c. Observing this indicator monitors the sensor built into the mixer body. When the nozzle for the water heating of water, the cost of which depends on the technical data of the device, heated the liquid to the norm, the sensor automatically turns the TEN.

Are there any deficiencies in the tap nozzle?

Yes there is. Users noted that the water heater per mixer, the price of which is significantly lower than that of other electrical appliances for heating a large volume of fluid, with long-term operation, water supplies a lower temperature. What does it mean? This means that if the mixer heating water functions continuously for 45 minutes - an hour, then the TEN ceases to have time to warm up the flow substance to the desired temperature. In this case, the nozzle for a faucet for water heating is cheaply purchased to heat the liquid to 45-500c. If you give the device to a breather, it will again begin to warm the liquid in the specified mode.

Experts also note that the water heater for the crane, the price of which is significantly lower than the cost of the boiler, requires checking wiring before installation. It is necessary to fear the overload of the power grid and closure. In addition, it is recommended to install coarse filters, otherwise the mixer with a heating element, which can be used only in foreign manufacturers today, fails after 3-5 years of operation.

No other disadvantages of the water heater on the mixer showed. Users for hot water devices for a crane in their reviews are positively responding about devices. Their main recommendation is to acquire a water heater flowing electric for a mixer in reliable manufacturers or suppliers that guarantee the originality of the device.

What manufacturers offer high-quality faucet nozzles?

So: You decide to buy a heating faucet for water, rated the market and designated the price category of devices, but what model do you not know what model? Let's figure it out. The most reliable water heater faucets offer only several manufacturers.

Budgetary crane for heating water offers TM "Akvaterm". It is as simple as possible in the installation, guaranteed working without failures for up to 5 years (this is confirmed by user feedback from the devices of this company) and heats up the liquid to 600C. If you need an inexpensive and high-quality tap for heating water, you can buy it from Aquaterm. The mixer has the maximum degree of protection: UZO, membrane isolation, pressure sensor and ground wire. But the most important device on the water heating faucet can be supplemented with a nozzle to the shower and necessarily has a filter for cleaning the water supply substance. The design of the crane heating for the water of this brand can be any.

Akvatermovsky faucet Crane Water heater is available in various color variations. You can choose a plumbing device for any interior solutions. Opinion of experts: Available in price Water heater flowing to akwaterm crane is an ideal solution for cottages, in which year-round and apartments live. Innovative mixer The heater is inexpensive and shows good performance.

Not bad respond about Kruss (China). The manufacturer offers an improved classic. Its models have a minimized and streamlined design, so the devices fit perfectly into interior solutions. It has a faucet for heating flowing water and structural differences - a nickel lever, a blue indicator light and a hardened flexible liner. Maximum water heating temperature 600C. The main advantage is the electric trailers, the price of which will be not much higher than the devices of the previous manufacturer, is equipped with a thermostat. The consumer itself can set the water temperature needed.

Delimano today offers the most advanced devices. The manufacturer can purchase an inexpensive electric water heating mixer with a display, which displays the current water temperature. Plumbing equipment looks stylish and bright, heats up the liquid to 600c. In this case, the nozzle on the water heating mixer is built into the plastic case, which it seemed impractical to some users - weak stability to the loads are scratched. The Deliman mixer with the built-in water heater will be able to function without interruptions if the water pressure is ranging from 0.5 to 0.6 atm. Users noted that the devices of this TM have an elongated electric pump - up to 1 m. In this case, the mixer flows through the jet pressure. Often in the plumbing equipment of this manufacturer uses aerators to save water - the jet is saturated with air.

The above manufacturers are listed, whose heating cranes for water are close in price and have maximum functionality, quality and safety. But the market can offer both devices from other manufacturers: "Aquastrum" (minimum dimensions of the device, a convenient system of electricity saving), "Corraveni" (ceramic valve, chrome surface, built-in water temperature control system) and "Rapid" (multi-level overheating protection). These manufacturers have the price of water heaters on the tap above - to buy them from the official suppliers of sanitary equipment.

Experts recommend to select a faucet for heating flow water in its safety characteristics. It is worth paying attention to the montage method. Do not choose models with short flexible liner hoses - a typical version of 60 cm. Also specify the supplier from which materials the case is made. The quality of the cartridge is also important. Durable and more practical will be instruments with ceramics. By the rest of the parameters, the water heated mixer is chosen as well as a classic plumbing device.
