Customer Question

Hi Andrew. My boiler's coming on for the hot water but not the heating. I've replaced the programmer but it's made no difference. I'm an electrician, by the way. Any ideas?

A standard system with a cylinder?

Do you have a motorised valve?

Customer: replied 12 months ago.
Two. It looks to be an S-Plan system. I shut it off to check the connections in the wiring centre and the heating came back up when I restored the power.

Ok, turn the hot water on and check which one moves for the hot water. Then turn on the heating and see if the other valve opens?
