Potterton Combi E133 boiler too much hot water

Hello All,

Somebody please help as very hot water is coming from my seven years old Potterton combi E133 boiler in taps & showers & because of this problem, I am unable to take shower or wash dishes. Should replacing the boiler will help me in this regard?

Thanks for your kind suggestions and help


Hi Jim,

After reviewing your problem, I would like to say that the thermostat is not working properly.  Nevertheless, the thermostat is always accountable for this issue whenever the central heating system of your Potterton boiler uses a cylinder or even container of the very hot water. It is better to replace the thermostat for rectifying the problem. However, as you said that very hot water is coming in taps & shower, then check the various taped up parts of a shower.
