Hi All,
I was away for a week and when I returned the tank upstairs over flooded due to a faulty float operated valve.Plumber changed that now but since the hot water pressure in the shower is low and the radiators don't warm up .I can't see a pressure gauge so not sure why is the heating not turning on although hot water is fine? Any advice is muchly appreciate it. thank you

on the right hand side of the boiler control panel, on the side bit, there is a small nipple , it is an OH stat try pressing that in, if it clicks that is your problem

Hi and thanks for your reply ,I keep seeing ppl say abt that reset button (nipple as u call it ) but I only have a red plastic that looks like an end screw which doesn't get pushed It's very close to the side wall so can't see properly but when u touch it that's what it feels like.I have asked for a plumber to come have a look as it's freezing Appreciate your reply
