    Heat Pump no Bypass valve - can damage occur?

    So ....silly question maybe.

    If my Heat Pump has a max recommended flow rate of 55 GPM and it is NOT totally hooked up yet (no power and no bypass valve) some parts are back ordered for a few weeks I am told.

    Is it OK to run my PUMP on HIGH to filter the water (flow rate of 95 GPM) - the water is simply running through the heat pump with no power, etc.

    Hope this makes sense.

    It seems the max flow rate should be 55 GPM. Still, I would contact the manufacturer with this question. You don't want to void your warranty....

    In general, no you shouldn't do that. However if it is only for a couple of days it will probably be alright.

    OK thanks.... just can't imagine what damage could occur....I get at high flow it can't transfer heat of course.

    toofast,

    The normal flow rate through the AquaCal heat pump is 30-70 gpm., 50 gpm being ideal. This is the range of proper efficiency. As you already mentioned, higher flow rates will decrease efficiency. High flow rates will not damage the heat pump on the newer units with the Thermolink Titanium Heat Exchangers. We do mention that the maximum PSI should not exceed 50 psi. though.
