How can we use electric boilers to save money for electric boilers?

First, rationally select the power of electric boilers.

The choice of electric boiler power must be calculated according to the heat load of the boiler in the heating room. The thermal load of different housing structure, room height, lighting area and room location is different. We suggest that energy saving building electric boilers can take 13-15m2/KW; ordinary building electric boilers can take 10-11m2/KW; villa and flat house electric boilers can take 8-9m2/KW; sealed conditions are not good, room height is greater than 2.7 meters, or houses with frequent access to people should be properly reduced the heating area per kilowatt of electric cooker.

Many electric boiler users believe that the smaller the power of the electric boiler, the lower the heating cost. In fact, on the contrary, the power of designing the electric boiler is not to increase the running cost of the heating period, but to save the running cost of the electric cooker during the heating period. The power of electric boilers used by electric boilers often fail to meet the heat load requirements of the room, which not only causes the electric cooker to be shut down or the electric boiler seldom stops, but also fails to achieve the ideal heating temperature.

Two, rationally adjust the temperature difference between the supply and return water of the electric boiler.

The current hot water heating system of electric cooker can be divided into three main forms. The temperature difference between supply and return water is as follows: in the low temperature hot water radiator heating system, the ideal temperature difference between the water supply and the return of the electric boiler is suitable for 20-25 degrees. In the low temperature hot water floor radiant heating system, the ideal temperature difference between the water supply and the return of the electric boiler should be 5-10 degrees. In the fan coil heating system, the ideal temperature difference between the water supply and the return of the boiler is 4-5 degrees. Proper adjustment of the temperature difference between the feed and return water of the electric boiler can increase the heat transfer coefficient, increase the efficiency of the electric boiler, and greatly reduce the running cost of the whole electric boiler heating period.

Three. Set the upper limit temperature of electric boilers reasonably.

The working principle of the electric boiler is intermittent work, that is, when the water supply temperature is less than the upper limit temperature, the electric boiler is in the heating state. When the water supply temperature reaches the upper limit temperature, the electric boiler is in the state of shutdown and heat preservation. On the coldest days of heating season, the calorific value provided by the electric boiler is just to meet or less than the heat load required by the room. Too high setting of the upper limit temperature of the electric boiler will cause the actual temperature of the water supply of the electric boiler to reach the upper limit temperature, so that the electric boiler will be in a state of heating for 24 hours.
