Draining radiators - Combi boiler
I am about to drain my Dads central heating radiators (to move pipes to
build a cupboard). I've drained rads before with conventional systems
with header tank, and refilled with inhibitor. Can anyone advise me
what to do with a combi boiler. My Dad says theres no header tank, so
does the system use inhibitor? Where do you put it in? And do you have
to isolate/drain the boiler to drain the Rads?
Any help would be much appreciated
