I have had to remove a radiator from my central heating system while I
have my kitchen rebuilt. I will not be in a position to reconnect the
radiator for several weeks.

I need to know if I can safely run the heating with the radiator
removed?

I guess it will all depend on the type of system I have and the main
question will be whether I have to connect the two radiator pipes
together to allow the water to flow, or if I can just run the system
safely with the gap in it.

I have a Combination Boiler (a Vaillant TurboMax) and it has
(alongside pipes for gas, mains water in, hot water out) two pipes
labelled:

CHF - I assume this means Central Heating Flow
CHR - Issume this means Central Heating Return

Can anyone give me any advice on what I need to do to run the system?

Thanks

Steve
