Our builders have installed a 250L horizontal Everflo cylinder with a thermostat that shuts off the hot water when the cylinder is up to temperature.

Hi All, I've got a Worcester Bosch Greenstar 30Si combi boiler and I'm trying to replace the room thermostat which has a faulty display. The faulty thermostat is a DT10RF optimiser which is discontinued so I purchased a Comfort 2 RF which is supposed to be the equivalent replacement. It...

Hi About 2 months ago we had a neat fitted and UFH with its own thermostat. The CH did work when it was first installed but with it being summer it was left unused. Now the Nest does not appear to be firing up the boiler. The green dot is on the heat link which means they're connected. The UFH...

I've got a what I think is called a multi zone heating system in my home, one for the main bedroom, and one for the remainder of the house, each with a wired in Honeywell thermostat. I've recently had a little one and will be looking to heat their bedroom at night while the rest of that system...

Morning all I'm walking through moving to a nest e from a neomitis and I was hoping someone could let me know if I've made the right assumptions about the wiring please? On the photos below am I right in thinking I need the brown live as the C wire on the nest and the black as the NO?

I'm replacing my thermostat with a digital one as the old one always overheats the house. The old one has three wires: The new Honeywell has a few options for wiring in the manual: I connected live (brown) to A and 3 (grey) to B, leaving the other two wires unconnected. When doing this...
