Pool Heat Pump

Thanks. I will try adjusting water flow today and see if that makes a difference.
The water connections are 50mm. The Heat pump is a Temperzone outdoor unit retrofitted with 3 x shell and tube heat exchangers in series.

So it is not a HOT WATER HEAT PUMP LIMITED model, just one that has been Knocked up.

Sorry, yes it is HOT WATER HEAT PUMPS unit. Model 7GP60-3T.
The name plate on electrical panel says it's a Temperzone OSA405RKTV.
You were right about the low water flow. Pool cleaner has noted that water level keeps dropping below skim drains reducing water flow.
Will check later today for an improvement.
