I have TRVs on 4 radiators and when the requested room temperature is reduced at bedtime and there is NO heat requested the boiler still fires up. Any ideas??

    Is there a Tado device connected to your boiler, if so what is it and how is it wired up, and do you have a combi or system boiler.

    It’s a system boiler, villainy ecotec plus 630 but I don’t know about the electrics
    There is a smart thermostat, a bridge and extension kit as well as trvs

    Have you checked the valves that send water to the hot water cylinder? Could one of them be stuck?

    If the radiators are coming on when there’s no heat requested, have you checked that the extension kit and trvs are in range of the bridge - you should be able to see if it’s losing contact on the graphs.
