Hi
Our system has started playing up with no hot water even though the radiators are all fine.
We have Potterton boiler with a fully pumped system with a 3way motorised valve and the usual tanks in the loft. Having done some searching on here my first thought was it's the motorised valve that's stuck. We have had it replaced some years ago.
BUT...
WIth the controls set to HW only all the radiators are hot. the pipe from the 3-way valve into the cylinder is hot (as is the one for the heating) which suggests it's going into the tank so why is it not heating it up.
Furthermore if I turn down the thermostat on the tank I can hear the valve motor kicking in.
So is it really the motorise valve?
Many thanks for any help you can offer.
