I've got a Worcester bosch greenstar 30si boiler. For the last 2 mornings a couple of the radiators have been warm(not hot) when the thermostat is turned to zero. Coincidentally the shower was used twice about half an hour before I noticed the warm radiators. Also the flow turned adaptor behind the flow sensor was changed two days ago so it was leaking quite heavily? Anybody got any ideas why the radiators are getting warm. Cheers.
Radiators warm when central heating off.

It might be a pipe connected incorrectly but if it's been working before and has just started causing problems then it's probably a fault with your three port valve. This is the valve that controls where the hot water from the boiler goes. It can send it to the radiators, the hot water tank or to both.
It's either stuck at "both" or the motor that drives it may be dead.
