Turn on Combi Boiler with no Radiators Attached?

Postby grogoreo » Sat Jul 13, 2019 8:16 pm


Is it ok, after draining the system and removing all but one radiator to turn on the combi boiler, in order to get hot water, until new radiators are installed?

I've left the pressure at 0 so haven't filled up the system.

Thanks, Greg
