With the tonnage of solar collectors and air to hot water which power consumption
work efficiently, like the four seasons Mu song launched ultra-low temperature air, at -25 ℃ efficiency will be able to work; the north of the Yellow River, solar collectors hot water project power consumption The amount is smaller.
resulting in no hot water in the rain and snow weather; and air to hot water works relative It is not affected by the sunshine, theoretically can be used throughout the year.
This question relates to what assistance is to be used in the hot water project of the solar collector, as well as the location and duration of the project. If you do not use auxiliary heating equipment, there is no doubt that the solar collector hot water project power consumption is minimal, but due to the uncertainty of the sun
