If there is no possibility of connecting to the gas network, and solid fuel heating unavailable then alternative way providing the house with heat becomes an electric boiler. This article will introduce readers to the Proterm Skat electric boilers, as well as provide instructions on how to start them.

Electric boilers Proterm Skat

This single-circuit equipment is made in a wall variation. It is possible to connect a water heater. Most models three-phase mains connection required, but models with a capacity of 6 kW and 9 kW can operate from a 220 V network. The selection of the required level of hot water and heating temperature is carried out using a display, which, by adjusting, helps to control the operation of the equipment. It is also controlled by a thermostat or an outside temperature sensor.

To create a certain level of heat, the parameters are adjusted individually. The power supply is controlled remotely from the tariff meter. For domestic needs, you can install units of 24 kW and 28 kW in a cascade.

Protherm Skat has:

• two-way pump;
• expansion tank;
• safety valve;

Also, the Protherm boiler can be connected via a voltage stabilizer. Electric boiler in action slow start, that is, for two minutes it "accelerates" and its power is minimal. The heating elements are protected from overload, their work is uniform, this is achieved by the ability to adjust the rhythm (1.2 or 2.3 kW).

Electric boilers Protherm Skat is distinguished by its low weight (only 34 kg) and convenient dimensions, which makes it possible to mount on almost any area. The boiler operation is reliably protected by several functions:

• pump blockage protection;
• a pressure sensor that monitors the water pressure level;
• frost protection;
• protection against blocking the valve and freezing of the water heater (when connecting the boiler).

If errors occur in the operation of the boiler, automatic diagnostics occurs, ending with the display of the results in the form of a code. The decoding of the codes is given in the instruction manual for the product.

Advantages and disadvantages of electric boilers Protherm Skat

Proterm Skat has a number of advantages over other types of heating:

• does not carry out harmful emissions into the atmosphere, since does not have combustion products, therefore given view heating can be called environmentally friendly;
• electric boiler - accessible view heating. It is used where it is not possible to connect to the network gas or can become an alternative form of heating;
• does not need systematic maintenance, unlike, for example, gas or solid fuel models;
• silent work;
• there is a heat level regulator;
• able to adapt to domestic water of not the best quality;
• resistant to voltage drops;

Consumer reviews

Consumers note that Protherm Skat provided an opportunity where it was problematic or even impossible to connect gas. With stable operation of the power grid, many refuse to connect the gas, while saving considerable amounts of money. In addition, an electric boiler is used in parallel with a gas unit, connecting them to a single heating system. This find allows you to significantly save money on resources, alternating them with each other during the heating season.

If you connect a water heater to Protherm Skat, consumers will be able to use them. hot water... Many people note the perfectly developed boiler design, which fits well into any room interior. You can successfully install it in living rooms due to its quiet operation, it will not cause increased attention to itself.

The disadvantages are that when using only an electric boiler, when it is turned off, there is no alternative options heating. Therefore, before making a purchase of the Protherm electric boiler, you should make sure that there are no problems with electricity. Experts recommend use a voltage stabilizer, to ensure the conditions for normal operation of the Protherm Skat boiler.

In addition, the increased energy consumption of an electric boiler causes negative emotions among the population, since paying bills is very expensive. If we compare the costs of gas and electric heating, then the Protherm electric boiler costs a little more, with identical heating parameters. From the above, we can conclude that this electrical equipment is chosen by those who do not have the ability to connect to the mains gas, as well as those who care about the environment and see it as a source of ecological consumption.

How to start the Protherm Skat boiler?

To start up the boiler, follow the instructions below.

When the pressure is low, the “bar” light starts flashing on the display. To remedy the situation, add water to the system. If in this case the pressure decreases, then you need to contact a specialist.

If you need to stop the Protherm boiler for a long time, you need to disconnect it from the power supply and turn off the taps. If you need a stop at winter period, then water must be drained from the system to prevent freezing.

How to care for a Protherm electric boiler? Do not use abrasive or chemical substances. Better surface wipe the housings with a damp cloth, then dry the surface.

Any malfunctions are indicated on the display by an error code. Code numbers are found and decoded in the product passport.

If a serious malfunction occurs, for example, the heat exchanger is frozen or water is dripping from it, it is prohibited to switch on the electric boiler into the power supply. It is necessary to wait for a specialist who will diagnose and perform quality repair... Parts are replaced only with original spare parts.

So, dear readers, you have met with the alternative type of heating Protherm Skat. When the gas and solid fuel out of reach or you are an adherent of cleanliness, an electric boiler can be a good help.

In the global market for heating equipment, Protherm products are popular, due to their reliability and high quality. Its equipment is supplied to many countries for corporate and private clients. The consumer can easily select heating equipment, because the model range reaches almost 100 items, including:

1. electric, gas, diesel boilers various modifications;
2. storage and instantaneous water heaters;
3. various sensors and automation for heating units.

In the line of heating equipment of the PROTHERM brand, the line of electric boilers for heating is represented by the Skat series. The company has created a wide network service centers that provide smooth operation heating equipment of the company adapted to the conditions of Russia. Therefore, it is profitable to buy an electric boiler Proterm Skat due to the presence of a network service... The official website of the company presents the Protherm product catalog for 2016. It contains the most current information about the heating units produced by the company.

In the company's catalog for 2016, the wall-mounted electric boiler Protherm Skat is represented by 8 models with powers from 6 kW to 28 kW. Equipment with the letter "K" is connected to a 220/380 V network. All models of this line of electric boilers are double-circuit. The company also produces a line of models of single-circuit boilers in their name there is an abbreviation - "KR 13". Single-circuit boilers are produced in the same power range as double-circuit. The dimensions and weight of all models are the same and their main difference is the power, which depends on the set of installed heating elements and the supply voltage (220/380 V).

The catalog provides basic parameters for an electric heating boiler Protherm of the basic model:

Advantages of Protherm electric boilers

Unlike gas, solid fuel and diesel heating boilers, they do not emit any harmful products, they do not need a chimney and various additional devices.

By its properties, the Protherm electric boiler is absolutely harmless to environment, and does not require constant monitoring during operation.

So, the Protherm Skat 9k electric boiler, however, like the rest of the company's line of electric boilers, is fully automated, on front surface The housing has an LCD display that reflects the set readings. The package includes detailed instructions to the electric boiler Proterm Skat 9, where all actions are indicated to achieve the coordinated operation of the unit.

It is enough for the owner to set the desired temperature, and in the future it will be maintained by the automation, with high accuracy up to one degree. After reaching a comfortable temperature, the thermostat will send a signal to the boiler control unit, which will turn off the power supply. Electric boilers are safe, because the automation monitors not only the temperature of the coolant, but also its pressure. To prevent sudden voltage surges, the boiler reaches the maximum mode in steps. A double-circuit electric boiler Skat of any model, in addition to heating, heats water for a hot water supply system (DHW).

Electrical heating boilers extremely compact and fit perfectly into any interior. Wall-mounted electric boilers Proterm Skat can heat areas from 60 to 280 m2 and are perfect for heating apartments, country houses, summer cottages and offices. Especially good reviews for the electric boiler Proterm Skat 6 kW, which can provide a small office with heat and hot water. There is an example when the owner installed a remote tank, the water in which heats up at night, since the night tariff is in effect in the region, and in the daytime it gives off heat to the room.

Installation and connection of electric boilers

In the installation and assembly instructions of the unit, included in the delivery of Protherm electric boilers, there is a warning that in the event of mechanical damage to the body, violation of the integrity of components and boiler blocks, the warranty becomes invalid. Therefore, at self-assembly you need to work carefully and clearly follow the recommendations. In order for the wall-mounted double-circuit electric boiler Proterm to function correctly, it must be connected in accordance with the requirements of the instructions.

Connection to the electrical network of the boiler Proterm 6 kW

The boiler with a rated power of 6 kW is available in two variants for connecting heating elements for 220 V and 380 V. Boilers and heating elements are no different and the 380 V boiler version can be easily turned into a 220 V version. To do this, it is enough to change the switching scheme. If the boiler is connected to a three-phase network, then heating elements for 2 kW in each phase consume a current of about 10 A, since the line voltage is 220 V. Therefore, a 1.5 square wiring and a 10 A three-phase circuit breaker will ensure normal operation.

With a single-phase network, everything is somewhat more complicated. The boiler has 6 heating elements and at a maximum power of 6 kW, the consumption current will be slightly more than 27 A, therefore, you will need a wire with a cross section of at least 6 squares and a 30 A circuit breaker. All of the above applies to any electric heating boiler for a house, of any power , only the values ​​of the consumed current and the required cross-section of wires will depend on the power.

According to the tables for section selection copper wire a current of 1 A requires a cross section of 0.17 mm2. The current in the circuit is determined by the well-known formula - I = P / U, in which:

The first thing to turn to Special attention- this is correct selection section of the electric power cable. Indeed, for example, an electric boiler Proterm Skat 24 with a rated power of 24 kW, when connected to a three-phase network, will consume a current of about 30 A for each phase. It is undesirable to connect such a powerful boiler to a single-phase network, because in this case, the current at maximum power will increase to 100 A. You need to connect an electric boiler only through an RCD.

As for the installation site, the requirements for the installation of electric boilers are not as stringent as for gas or solid fuel units. And the price of an electric boiler for heating a house is much lower than the price of other types of boilers.

You can install an electric boiler anywhere, but this place should provide easy access for adjusting the unit or promptly shutting down if necessary.

If several electric boilers are provided in the circuit diagram, then they are connected in parallel. According to the rules for electrical safety, electrical heater must be grounded.

How to choose an electric boiler for home heating

All are compact, easy to operate and safe. They do not need chimneys and special rooms for installation, and the efficiency is close to 100%. These properties are superior to other types of boilers. For heating a specific room, an electric boiler is selected primarily in terms of power. It is believed that one kilowatt is sufficient to heat 10 m2. Therefore, the electric boiler Proterm Skat 12 with a nominal power of 12 kW can provide heat to a room with a total area of ​​120 m2.

The high quality and reliability are confirmed by the reviews found on the network on the Proterm Skat 12 electric boiler, in which they write that the boiler is silent, simple and easy to regulate and does not require constant attention ("installed, turned on and forgotten").

Popular electric boilers from Protherm

To connect as a backup to the existing system heating or to heat a small house with an area of ​​up to 90 m2, the wall-mounted electric boiler Protherm Skat 9 kr 13 with the possibility of using a 220/380 V network is in greatest demand. Single-circuit boiler with electronic control and with built-in circulation pump and . Its main characteristics are fully consistent with the base model.

If there is a need to organize hot water supply, then the manufacturer has provided for the possibility of connecting an external tank. At the time of sale, the connection nipples are closed with plugs. The difference in price between single-circuit and double-circuit boilers small. For example, the price of a Proterm Skat 9 kW wall-mounted double-circuit boiler is comparable to the price of a boiler of similar power, but single-circuit. In different stores selling heating equipment, the price of an electric boiler Proterm Skat 9 ranges from $ 490 to $ 560.

According to their technical specifications, according to the requirements for installation, regulation and design, electric boilers are much preferable to gas and. For their installation, a separate room is not required, and the electric boiler itself can be installed anywhere in the heating circuit, the main thing is that there is free access to it. Electronics, developed by Protherm, independently monitors the air temperature in the room and creates comfort and coziness at home. The only obstacle that limits the use of electric boilers is the high price of electricity, which tends to increase.

In those houses where it is impossible to use gas as an energy source for the heating system, its replacement in heating system electricity can become. It is on it that the electric heating boiler Proterm works. Due to some of its features, such equipment is becoming more and more popular every year.
