This is the wiring block on my Worcester Greenstar 27ri boiler. I just want to check that a dual channel Nest Heat Link will work with it? If it's simple to wire up, a nudge in the right direction would also be massively appreciated. Thanks very much, Simon

I'm thinking of replacing my old digi stat 4 with a more modern (possibly with Alexa controls) thermostat, as I live in rented accommodation I can't do any wiring so just replacing my stat will have to do. Behind my current stat I only have two wires going to the pins on the backplate one red...

I am replacing my old Drayton RTS1 thermostat with the Meross MTS200B and I don't get the heating switching on. I thought it was going to be straightforward but at this point better to ask for help than screwing something. The old thermostat wiring is this one: The new thermostat has this...

Hi, I have an old style back boiler and can't get my ch work. The dial on the thermostat is on maximum but heating comes on only when it's extremely cold. Hot water works ok. I'm thinking the thermostat could get dusty inside as we did some plastering but no changes after I cleaned it. I...

I have a 2.5kw Creda 79351 that looks to have recently burnt out its neutral wire at the 13A wall switch, the fuse looked to be ok. I'm presuming it's an overheating issue of some sort and that the thermostat is at fault but wanted to confirm. The thermal fuselink is intact. The resistance on...

Hi All, We're in an absolute mess. Recently we've had a plumber come out to fix our heating and hot water. Both had stopped working. The first time he came, he changed a pump. This fixed the hot water - but the heating wasn't working. About a month later, he installed two new valves (Drayton &...

Hi, I have a Vokera Easi-Heat Plus which was working perfectly until i had a electrical safety certificate. Now the central heating only works on the timer and not manually on the thermostat. Hot Water also fine. Any assistance gratefully received. Thanks

Good Morning, I replaced all my old unipor mechanical thermostats with the Honeywell DT90E's a few months ago. All was going well until the one in the room that uses the most heat started constantly clicking on off like a clock. I read on here that if a reset doesn't fix it then the thermostat...
