    Hi,

    I can't seem to get the central heating to switch on. The hot water works fine and I recently bled the radiators which made the pressure drop to 0.6 bars. I've re-pressurised the boiler to read 1.0 bars but it doesn't seem to make a difference. It's a glow worm betacom 24 boiler.

    Any suggestions would be great.

    Do you have a built in timer ,or external programmer . Do you have a wall thermostat ?
    Are all of the above calling for heat ?
    Does boiler fire up for central heating ,but extinguish quickly , or not firing up at all ?

    Thank you for your reply, it has a built in timer and I've switched it onto the continuous setting to check the heating and I can't hear it firing up at all but it seems to have no issue firing up for the hot water. The wall thermostat is definitely working as it had ran out of battery but replaced it with new ones.

    Has the heating worked since you changed batteries ? What stat is it ?

    It's not worked since I changed the battery and shows a temperature of 16°C with a bit of fluctuation.

    Looks like a problem with the stat. Try raising the temperature. Or it's not communicating with receiver.

    After changing the batteries, is there a reset button to press?
    Batteries fitted AOK ?

    I've raised the thermostat to 24°C and left it and the temperature stayed the same.

    I'm assuming the batteries are fine because the digital screen is on

    Thanks for the help, might just need to call someone to come take a look

    Check the reciever ,it may need re set. Failing that call in a pro.
