I recently had a problem with my potterton puma 80 where the heating was getting hot with the hot water running.
Also the central heating barely got hot and was very slow in operation.
I replaced the wax capsule and now it seems fine the central heating gets nice and hot and the hot water flows without heating up the CH.
The only problem (if it is a problem) is that when you shut the hot water tap off you get a burst of heat shoot up the flow for the central heating and consequentially heats the radiators. Does anyone know whether this is normal or if i have another problem. All help will be greatly appreciated.
