Associated Heater Solves Frozen Problem of Feed Water Line of Solar Heater

Wang Jun Tianjing University  
The wide utilization of vacuum glass tubes made the application of solar water heater in winter became realizable,but in the winter in Northeast part of China and high-mountain area,the feed water line may be frozen,even though it was insulated.Using an associated electric heater with automatic temperature control,the frozen problem of feed water line can be solved completely.
