Hi everyone I am at the end of my tether. I knew I had a problem with the three-way valve (Honeywell) because I could only get central heating if I turned the HW button on too on the control panel - I have separate buttons for HW & CH. A plumber came out on Wednesday and replaced the motorised...

The outlet pipe on my hot water cylinder is constantly cold to the touch, the water in the tank doesn't last the day. I have bled the pipe and the hot comes through eventually. When bleeding, the outlet pipe becomes hot again but is cold almost as soon as I close it back up. Attached pic with...
