radiators get hot downstairs also and we only noticed it this year when we have turned off the central heating but we don`t think it was like this last summer when we moved here. And I have taken the motorised bit off and moved the spindle by hand and the rads still get hot.
Help!! When I turn on the boiler to get hot water I also get the radiators getting hot. I thought it may be the motorised and diverter valve but it still does the same after changing these. Has anybody got any ideas as to what I can do.
