Ensuring the Correct Water Flow Rate for Your Heat Pump

Most of our pool heat pumps state the required water flow rate on their specifications table. If the water flow rate is too low, then the water in the heat pump will overheat and the heat pump will switch off. Check the water flow rate from your pool pump and through your filter to ensure that it is high enough for your pool heat pump. Note that there is a maximum possible flow through each size of pool pipe regardless of the power of your pump. For larger heat pumps it may not be possible to achieve sufficient water flow through small pipes (eg 1.5″ pipes). Please contact us for advice on this. We sell water flow meters that will show you the flow rate through your pipes. See our “Accessories” section You should also regularly backwash your pool filter to ensure that the water flow rate remains at an adequate level.
