No hot water I have a boiler that comes with a cylinder tank in airing cuboard, I’m not getting no hot water whatsoever the heating is working, but unless I turn on the switch in the airing cuboard It will then get hot?
I’m sure I read the switch in the airing cupboard next to the tank is the immersion switch which is used in emegencies but unless it is on I am not getting any hot water and scared of running up a high bill.
