Solar collectors and tank water can not cycle what is the reason
pipeline loop problem. If there are other piping behind the pump, pay attention to other pipeline valve opening and closing situation
If the exhaust valve is not installed, theoretically through the collector outlet pipe directly discharged to the tank, the water part of the pipeline gas block the possibility is not large.
air block, including the pump inside the air, and the pipeline part of the air two cases. The pump has a bleed screw, open the deflated and then screw on it, if the pipeline is air block, the general solar energy is installed during the pre-set the exhaust valve, check the exhaust valve is not blocked.
Pipe clogged. If the exclusion of the other two cases, then the possibility of a large pipe block, including the pipeline frozen, debris blockage are possible, if the pump is easier to burn the pump, need special attention.
