Hi everyone
Just moved into house. i have a potterton promax SL conventional boiler. Less than 5 years old.
There is an unvented hot water cylinder upstairs.
i have the hot water cycliner coming on between 7 and 730am each day.
i went outside in the garage earlier, around 530pm and heard snd saw the boiler firing up. Checked Gas for today and since around 8am had used 0.4 of a unit. The heating has been off allday?
i suspected it was using gas during the day, even though everything is off. Can’t understand why???
Cheers
Neil
