I have Glow worm ultimate with megaflo, the water pump was replaced and the pcb in the boiler were replaced as they seem to be faulty it now working ok now with hot and heating. My concern now is that water pump seems to be on all the time even when the thermostat is off for both heating and water, and very hot. I was expecting the water to turn off but it remains on and all pipes on megaflo that return hot water seem to be hot all the time. Should the water not turn off any ideas on how this should be configured to turn off please.
