What to Note When Using Electric Heating Boilers

When selecting electric boilers, it's crucial to choose one with the appropriate power. The power of an electric boiler is determined by the area of the room to be heated, the room's lighting conditions, and the room's environment. Experts recommend using 13-15 square meters per kilowatt for energy-efficient buildings, 10-11 square meters per kilowatt for standard buildings, and 8-9 square meters per kilowatt for one-story buildings. For rooms with high ceilings or poor insulation, reduce the heating area per kilowatt of the electric boiler to achieve effective heating.

Next, it is essential to adjust the supply and return water temperature difference of the electric hot water boiler. In low-temperature hot water radiators, the ideal supply and return water temperature difference for the electric boiler should be adjusted to 20-25℃; in low-temperature hot water floor radiant heating, the supply and return water temperature difference for the electric boiler should be adjusted to 5-10℃; in fan coil heating systems, the supply and return water temperature difference for the electric boiler should be adjusted to 4-5℃. Properly adjusting the supply and return water temperature difference of the electric boiler helps to improve heat transfer efficiency and reduce the operating costs of the electric hot water boiler.
