Thermosyphon Solar Hot Water Heater question about Expansion Tank
Thermosyphon Solar Hot Water Heater question about Expansion Tank
(OP)
In a thermosyphon solar hot water heater, assuming there is a backflow preventor/check valve from the city supply, does it require an expansion tank or does the storage tank above the collectors act as a tank for some expansion as well?
Thanks
Thanks





RE: Thermosyphon Solar Hot Water Heater question about Expansion Tank
Consider the effects to the panel and piping if you don't. Actually, the expanded water should weep out the PRV if you don't have an expansion tank....either that or it will cause pipe/joints to fail in the solar panel.

1) between the backflow preventer (from city supply) and storage tank?
2) or between the storage tank and the solar collector?
