Many owners of private houses try to reduce installation and operation costs and simplify the heating system through the use of electric boiler for heating.
Types of boilers for heating a house
There are two types of electric boilers: flow and storage.
The first feeds hot water into the system a few seconds after turning it on. However, such a device very heavily loads the electrical system. Therefore, you can use a flowing boiler for heating a house only with powerful and high-quality assembled wiring.
Storage boilers are containers in which water is heated and stored until it is used. They are used, as a rule, as electric boilers for heating.
How to choose a boiler
An electric boiler for heating is selected by power. If the power of the device is 6 - 10 kilowatts, then it is designed specifically for use as a heating device. Attention should be paid to the tank volume. The larger it is, the less often the heater will have to work. Domestic boilers are rarely more than 100 liters. Industrial models have capacities of 300 or more liters.
- In electric boilers for heating, the pipe leading to cold water is located below, and the outlet of warm water is from above;
- Boilers for heating a house have inlet openings of a diameter of 2 inches or more, while domestic boilers have 1 \ 2 or 3 \ 4 inches;
- The capacity of a boiler for heating a house is calculated on the basis of 1 kilowatt per ten square meters of a house.
Calculation of the heating circuit with a boiler
The branching of the boiler heating system significantly affects the quality of heating. The more radiators and branches, the lower the speed of the water in the system and the cooler the room.
If, when calculating the heating circuit, the boiler took into account the “lower limits” for the area of the room, gradually the performance of the system will decrease. That is, it will be necessary to change the ten to a more powerful one or to increase the number of heating appliances in the house.
The quality of boiler heating is very dependent on the cleanliness of the pipes and the heating element. Therefore, you will have to call service from time to time or clean the system yourself.
System features
Constant and uniform movement of the coolant is ensured by the circulation pump provided by the boiler heating circuit.
Since the electric ten is switched on without interruption, and the water in the system is constantly changing, a large amount of scale accumulates on it. Therefore, you should prepare for its frequent replacement in the electric boiler for heating.
