当前的电锅炉热水采暖系统可分为三种主要形式，其供回水温差如下：在低温热水散热器采暖系统中，理想的电锅炉供回水温差宜采用20－25℃.
Electric boiler heating system the current can be divided into three main forms, the temperature difference between supply and return water are as follows: in the low temperature radiator heating system, the difference is 20 to 25 DEG C for the return water temperature electric boiler is ideal.
在低温热水地板辐射采暖系统中，理想的电锅炉供回水温差宜采用5－10℃；在风机盘管采暖系统中，理想的电锅炉供回水温差宜采用4－5℃。
In the low temperature hot water floor radiant heating system, electric boiler is ideal for temperature difference is 5 to 10 DEG C; the fan coil heating system, the difference is 4 to 5 DEG C for the return water temperature electric boiler is ideal.
适当的调节电锅炉供回水的温差，可以提高传热系数，使电锅炉效率变高，能够大幅度降低整个电锅炉采暖期的运行费用。
Proper regulation of the electric boiler supply and return water temperature, can increase the heat transfer coefficient, the electric boiler efficiency is high, can greatly reduce the operation cost of the whole electric boiler heating period.
电锅炉工作原理是间歇工作，即当供水温度小于上限温度时电锅炉处于加热状态，当供水温度到达上限温度时电锅炉处于停机保温状态。
The working principle of the electric boiler is intermittent operation, 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 stopping heat preservation.
在采暖期*冷的几天，电锅炉提供的热值刚好满足或小于房间需求的热负荷，过高的设置电锅炉的上限温度值，会造成电锅炉实际的供水温度很难达到上限温度，这样电锅炉就会处于24小时加热状态。
In the heating period, the coldest days, caloric value of electric boiler provides just meet or less room needs of heat load, maximum temperature setting value of the electric boiler is too high, will cause the electric boiler actual water temperature is difficult to reach the upper limit temperature, so the electric boiler will be in 24 hours of heated state.
