Heating on Hot Water only but pump continues to feed heating Help and information on all topics relating to your central heating, air conditioning and ventilation issues.

My boiler is programmed to heat the water only twice a day. During those times the central heating pump comes on as well and pumps water through the rads. The sound of water pumping round the system is very noisy. How do I stop it???

Hi. Itrs a Potterton Suprema 30-80, wall mounted fan assisted balanced flue gas boiler

There'll only be one pump and a 3 port valve, check the 3 port valve and actuator - it's probably the actuator that is faulty.

Hi,

5-1 favourite to be the actuator, it always is.

I might move into research on the production of an infallible actuator, what do you think htg engineer, split the profits, there is bound to be some!?
