    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.

    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.

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