4 main criterion for choosing an electric boiler

Power heater

first and most important selection criterion - capacity of the equipment.This parameter is determined by the area of ​​a private house or apartment.Usually when calculated by the following formula:

W = (40 * Vpomesch + + Qokn Qdv.) * K ,

where:

• W- rated power of the electric boiler;
• 40 - the average value of the equipment required capacity of 1 m3 of space, W;
• Vpomesch - the total amount of heated space (all the rooms in the house or apartment), calculated as the total area of ​​housing, multiplied by the height of the ceilings;
• Qokn - heat loss at the windows (100 watts each);
• Qdv - heat loss on the door (200 watts each);
• k - coefficient disposition region (southern band - 0.7-0.9; and European central part - 1.2-1.4; the north and east - 1.8-2).

This formula is suitable when you want to select an electric power boiler for heating the apartment.As for private homes or cottages, that the calculations should be the final value multiplied by 1.5.An additional factor takes into account the heat loss through the ceiling and the floor.

type of heating element

second, equally important criterion for the choice of electric boiler - by the method of heating water for heating.To date, there are electric heaters, induction heaters and electrode.

first found in the windows more often.They can be as floor and wall (hinged).Equipment with Taine inside is less likely and can be used both in private homes and in the apartments with a voltage of 220V or 380V.The disadvantage of this type of electric boilers - the scaling of the tubular heaters.In addition, the power of the electric boiler may not be enough for a two-storey house, and set the number of heaters is not always possible due to their size.

In this regard, the choice of induction boiler - a more reasonable solution.Because of their small size (seen in the photo below), these heaters can be connected in a single heating system, which will increase its capacity up to the required value.The only obstacle - the higher the price of the equipment.Induction electric boiler heating can be selected for an impressive garden area.A very important advantage of induction tools - they are the most cost-effective, which is especially important when installing heating in large buildings.

And the last type of heater - electrode.Such devices are the most secure, but at the same time and in the most intricate heat carrier - water.At a cost not much of a difference you can feel, but still most often the choice of an electric boiler with ion heating method is carried out for private houses and holiday facilities.

From my own experience I would say that 4 years ago I was advised to choose an electric double-boiler Protherm company.During this time, the device never failed, and at the same time the price was one of the cheapest in the store, so my review - "Proterm" is the best manufacturer of household heating units.

Additional features

If you decide to choose a good electric boiler for heating private houses or apartments, then look for the presence of several very important functions:

1. presence of multifunctional control systems, which clearly displayed.Your unit should be equipped with temperature and pressure sensors, as well as the possibility of fine adjustment of water temperature.If the system pressure drops, you may notice in a timely manner and as soon as possible to rectify the situation.
2. ability to automatically select the power for heating operation.To save electricity, the boiler can independently modify the heating power during operation.
3. ability to use the electric boiler for hot water at home.Most modern techniques can be used not only as heating equipment, but also as a boiler.Very convenient, but the power consumption, as you know, is increasing.

This is done by parameters independent choice of electric boilers.We hope that you now know how to choose the right electric boiler for heating homes, apartments or cottages and last but not least - how better to give preference to firms!
