Cheap heating homes with electricity: the choice of economical boiler

The increasing popularity won the way to the house heating using electricity

direct heating system

Direct heating is realized by the use of electric heaters: convectors, underfloor heating, Electrical oil radiators. By using this option, there is no need to lay pipelines, install the boiler, radiators buy. All devices are connected independently to the cabling. Temperature is regulated separately for each heater, which enables to control power consumption.

Important! The use of direct heating is the most costly heating method. The advantages of this system include savings in capital (equipment cost) and operational (maintenance) costs.

Indirect heating system

Cheap heating homes with electricity - is an indirect heating. It consists in the fact that the classical water heating remains unchanged, simply replaced the coal or a gas boiler on electric. They come in the following types of heating:

• Inductive - economical embodiment, here the heating current is produced due to a high frequency (radio frequency waves);
• electrode or the ion exchange - public electrodes to which a current (50 Hz) are used in this type of heating;
• line - water heated through the heater. This type consumes much more energy and quickly breaks down, but the cost of the boiler several times less than that of the unit with inductive or electrode heating.

The advantages of electric boiler should include:

• small size;
• low cost;
• quick installation;
• operational and environmental safety;
• quiet.

Useful advice!Although the prices of induction heating boilers for "bite" of a private house, the power consumption in these models is one of the most economical. To really experience the economy and see it in electricity bills, it is advisable to install a three-phase boiler.

Why heat the house with electricity is cheap: the calculation

Not to be unfounded, we give a clear example of a cheap home heating electricity with the help of the boiler. Calculate the real cost savings for the house with an area of ​​100 m²:

1. Electric boiler efficiency almost always gives 100%. On average, 1 kW thermal energy expended 1.03 kW electricity.
2. According to the approved tariffs in the Moscow region in 2016 for consumers (population) rate to a single rate of 3.18 rubles.
3. Coefficient of thermal heating costs 10m² is 1 kW, in this case, a 10kW heat to the area of ​​100 m².
4. The average daily rate of energy consumption of 1 kW per hour, hence 10 x 24 kW = 240 kW hours.
5. Assuming continuous operation of the boiler for a month (which is unlikely) kilowatt cost will be: 240 x 30 = 7200 kw.
6. In the month to pay for the waste heat: 7200 kW x 3.18 = 22896 rbl rbl.

Three-phase electric boiler

The three-phase boiler is more powerful than a single phase, and is suitable for installation on more than 100 m². That the network can withstand the load during operation of the boiler, they produce three-phase, that is, they are connected to the network at 380 V. Features three-phase boiler:

• powerful. It is necessary to take into account the heated area. At 10 m² requires 1 kW + 10-20% (for stock);
• powered by three phases (380), it is necessary to increase the capacity of the current supply in the building;
• necessary to obtain a special permission in distribution and sales to increase the power consumption and the installation of the boiler;

Cheap home heating electricity with backup heat source

The boiler electricity may be interrupted due to power failure, failure in the line, breakage or wire circuit, so the use of a combined boiler (wood / electricity) will not leave you without heat house.

for heating boiler with wood and electricity – is a reliable, versatile, functional unit, through which you can ensure the continued heating of the house. This boiler can operate on solid fuels (wood, pellets, wood waste) and electricity at the same time. This versatility is possible due to a unique well thought out design of the equipment.

The cost of the resistors of the boiler several times less than that of the unit with inductive or electrode heating

Construction of a combined boiler for heating with wood and electricity

A distinctive feature of the combi boiler is the presence of PETN. A fireplace for wood placed in the bottom of the unit. When burning wood thermal energy heats the heat transfer fluid and heated fluid (water) is directed into the water heating system. Such boilers are equipped with devices that are responsible for the automatic on / off heating element depending on the set flow temperature. When wood is burned and the heat in the furnace decreases, and the water temperature drops, the work turns heater and the boiler, consuming electricity, maintains the desired temperature. All manipulations occur through automation.

Electrical apparatus combined timber-boiler

Power heat released during the combustion of the solid fuel is 25-35 kW. This power is enough to heat the room at 100-120 m² and a heater is used to maintain a stable temperature in the house. Combined heating systems are especially popular in the private sector, as the cheap fuel is used to heat the room. With built TENam, it is possible to vary the heating mode.

Electrode boilers for heating private houses: reviews

heating system using electrode boilers is relatively new. For warm-electrodes are placed directly in the water. In the process of supplying current potential difference occurs in the water and ions begin to move actively. When they move a lot of heat, which heats the water in the coolant.

Here are a few comments about the electrode boilers for heating private houses:

"In our village is constantly problems with electricity, the current strength is unstable, sometimes it drops to 180 V. Gas in the village no. Very long enjoyed wood boilers, but there were problems because of their need to constantly throw up, and all day at work. A friend advised the electric boiler. Long thought what to take, the choice fell on the boiler with an ion type of heating because it can withstand power surges, while continuing to work. "

Valentin Chutuev, Moscow

Electric boiler manufacturer Rrotherm

"To build a house in the private sector, left the apartment the children. When done heating, immediately decided to put an electric boiler. Bought children electrode boiler. At first I was indignant that it is expensive, – and you can find cheaper, but when we went for the weekend to visit the children, and we broke through the battery, all the water is drained out and the boiler just stopped working – not broken, not burned, just hung up. That's when I do not regret the money spent. "

Valentina Petrova, Volgograd

An example of a three-phase electric boiler apparatus

"I decided to deliver cheap heating for the house, electrical. The best I found - it ion boiler, it is 30% more economical of electric heaters. The whole trick is to save that energy of the boiler immediately sends to the hot water, while a pot Tan spends part of the energy for heating the heating element itself. "

Peter Korneev, Surgut

From yet seen that the electrode boilers can operate under conditions of unstable voltage (if current jumps - up to 40 kW) is not fail if for any reason there is no water in the system, and are the most economical in the line of electric boilers.
