Thanks Hot Rod. This is what I thought.

    Just want to know if there is a possibility of damaging a flat plate heat exchanger when only one pump is running. That is, the input pump circulates while the output is stopped.

    Thanks,
    Luc

    It is between 140F and 180F on the input side. There is a glycol solution on the output side.

    I don't

    see a problem, check with the manufacturer to be certain. If it is a brazed plate HX it is assembled under much higher temperatures.

    180F is not too high to stress the glycol, either.

    Thanks hot rod. I thought the same thing but I wanted to check out with someone on the Wall.

    Also, I just want to say that I appreciate your articles in Phc News. I am looking forward to your future webcast on solar radiant.

    It may thermo siphon

    also, on the "off" pump side. Unless you have good check valve or flow check protection.
