Recently got my whole central heating system changed (replaced the old boiler to a Potterton Suprima, and repositioned the boiler and changed all the radiators as part of building an extension).
Following this, [b]whenever the hotwater is swiched on the radiators are getting heated.[/b]
My plumber came and changed the 3way valve, but the problem still exits. He too is puzzled by this! Could someone advice could I do?
if you have had the valve changed then you are looking at reverse circulation ,
this occurs when the last heating return tee joins the system after the hot water return tee,the hot water should be the last tee back to the boiler if you have a radiator circuit joining after the hot water you will get reverse circulation,ask the plumber who inmstalled this to check where the COMMON TEE return is if he knows his stuff then he will realise his mistake and try to reconfigure the pipework
