    Hi I have just had a Ideal logic c 30 Combi boiler fitted and I’m having an issue with the radiators going cold after a few hours?
    Yesterday after the boiler was fitted everything was fine but then the radiators went cold after 2-3 hours. today I have had the same issue and they have gone cold after 2 hours.
    The hot water is working at all times even when the radiators to cold. The pressure is just below 2 and is fine.

    im running the boiler in eco mode however even when I take it out of eco mode the radiators still remain cold.

    Any suggestions as to what this could be?

    many thanks

    The trv shut off radiators when the ambience reaches selected temperature.
    Also, in main zone, the thermostat will do the same thing.
    Has the ambience reached the selected temperature?

    If you've just had it fitted I'd suggest you get the fitter back to look at it.

    How do I find the ‘selected temperature’? And how would I judge if the ambience has reached this selected temperature?
    Thanks for the reply btw

    17°! I'd freeze at that temperature! Is there a TRV in the same room as the thermostat?

    Turn all TRVs to max and set the room stat to 22 deg if everything now works it is simply getting used to your controls

    Are TRVS are the valves on the radiators? So set them to max in every room?
    How do I change room stat to 22?

    thanks again

    You can't have a valve like that in the same room as the thermostat. Turn it up to max or take the head off.
