Sorry my hot water is working but my central heating is not, my pressure is fine and I am using a Honeywell thermostat which is set on continuous running for both at the moment
Usually leaked water from the spindle of the hot water proving switch into the microswitch causing a permanent demand for hot water.
Thanks does it mean I would need a callout or is this something I can fix myself?
Ollski how do I fix the constant demand for hot water? Would I need to change my zone valve actuators for the heating?
I changed the valve but still the valve for the heating doesn't open

I thought that he was going to call a pro?
