Potterton Suprima that keeps comimg on

[pdcleeds]

Hello i have a Ptooerton Suprima boiler that fires up every half hour even when we dont have the heating on or hot water its doing my nut in as it wakes me up all the time. Does anyone have any ideas what the cause of this could be. THANX

It's most likely to be a fault with the external controls. What control system and valves have you got?

Do you have a 3 port zone valve ? ('Y' Plan system)
