    Nest v3 - heating not switching off

    Can't find an identical problem, so here goes. Nest v3 installed in the summer, by my local gas engineer. Don't want to bother him again as he took pity on us and charged us an unbelievably low price to sort out many issues left by a previous cowboy. Heating and hot water are on a Y plan...

    Advice on wiring Nest Thermostat E to Alpha Eco Combi Boiler

    Hi, I.m looking to add a Nest Thermostat E to my Alpha Eco Boiler. The boiler has no room stat but just a timer. My understanding is that I should leave the timer in and set it to always on. I should then remove the link connecting 1 and 2 and run instead two wires from 1 to NO/Call for heat...

    Replace Drayton with Nest - wiring?

    Hi, I'm not sure if my programmer can be replaced with a 3rd gen Nest? Google website says my wiring means no, but I don't believe that's true. Do I need to modify any wires or add anything? I know there's threads discussing similar, but I'm still not sure. I have a Drayton (British Gas UP2)...

    Which smart thermostat for Vaillant Ecotec 831 plus?

    I’ll try to keep this as short as possible! Basically the timer has died on my Ecotec plus 831 combi and rather than just replace it with similar I was thinking now maybe the time to go smart and get something that can help my heating system run more economically as we’re off grid so run off...
