Hello again everyone, I have a second problem with our heating (The 1st one was for my daughter) The boiler is an old Potterton RS 50/15 conventional boiler.Same age as the house we're in (at least 30 + years old !) guilty of not having regular servicing done. Since saturday we have no heat in the downstairs radiators.Upstairs are all ok as is the hot water. When thermostat is turned up the boiler fires up ok but no heat downstairs ? we have bled the radiators and they are fine. Is it the pump at fault or something more serious? the expansion tank in the loft was a bit low but held the arm up to fill up a bit more. Any suggestions ?
