Potterton Netaheat 10-16 Problem?

Theres a valve - often in the airing cupboard close to the water tank that directs the pumped water to either radiators or hot water tank - or both. Your motorised valve may be stuck in the CH position. You can sometimes move them manually with a little lever - do not worry if you think you're fighting against the little electric motor inside it.

Good luck...
