    Radiators off, boiler switched off - can I turn the water on?

    The radiators were taken off and the boiler was switched off as was the water supply. Would switching the water supply back on cause a leak? The only taps are the bathroom and kitchen which have their own stop valves. The toilet has not been removed.

    Plasterer removed Radiators - one pipe has come off

    So the plasterer has removed all the Radiators from the walls. The boiler Vaillant Eco Tec Plus 28 is showing a F22 fault - I assume this is due to the fact there is zero pressure in the CH as its been drained. 1) Do I just leave the boiler as is or switch it off ?- I do not need water as...

    2 radiators on with hot water only

    Can anybody let me know if they've experienced 2 radiators gettng warm upstairs (both above the boiler) when the boiler is only set to hot water. It's a four bed house and the other 4 rads upstairs don't get warm so I'm guessing not divertor valve related which is only a couple of years old. I...

    Removing radiators for decorating

    Looking at redcorating our whole house so was wondering whether it's better for the CH system to do it one by one or remove them all at once and then put them back all at once? Should radiators be removed for decorating room by room and then once the room has been decorated to replace it...

    Hi. I've an oil-fired condensing boiler (11 years old) in the garage which has two external pumps (Wilo RS50s). I decided to flush out the system and after emptying it via the lower ground floor radiator added Fernox F5 to the tank and turned the supply back on. Running the system leads to the...

    Can the rad tails on kudox radiators go far in?

    Hi guys, I have fitted a new radiator and had a few issues working things out once I put it on the bracket. I screwed the tails in until the threads were no longer visible. The tails were too far out of the rad/too long and couldn't align the valves with the pipes. So I twisted them in further...

    Hot water coming out of the hot water storage cylinder into upstairs radiators after heating/HW turns off and running out of hot water in the mornings. I have a Glow Worm 24HX Condensing boiler on the ground floor with a pump in the same cupboard, a hot water storage cylinder in the airing...

    Apologies if something like this already been covered. We have new underfloor heating and new radiators upstairs.
