I have a Worcester 28 and need to know if I can drain down the hot water
(and cold supply) and yet still leave the central heating side pressurised
I need to leave it running to try to prevent freezing but would prefer to
turn off at the main stopcock and run off the cold and hot water.
I would hate to damage the boiler though, by it not having water in a
section that gets heated.
Any advice please?
Thanks as always.
