    Ive temporarily removed a radiator for decorating.

    The TRV is set to zero. and the central heating switched off.

    The valve at the other end, with the lock shield is dripping slowly ( even though the lock shield is closed)

    I got a couple of these to solve the dripping problem while i decorate.

    If i wanted to switch on the central heating for the rest of the house is it safe to do so with the blanking valves fitted or is best to keep the CH switched off until i refit the rad?

    crack on, its just the same as if you had turned a radiator off,
    the water will still circulate around the rest of the system no bother.

    if you ave a combi boiler or a sealed system then you should have a peek at the pressure gauge and make sure thats ok before turning on.
