Hi All
I am about to start work on my central heating. I currently have a Gloworm Swiftflow 80, (12 years old), combi and a sealed system.
I am changing the rads and then paying a Corgi Plumber to install a new Combi (Vaillent ecoTEC 831).
My original plan was to turn CH off on boiler, drain the system, change all the radiators over the course of a few weeks. Flush the system with Ferox before having the plumber in to change the boiler and finish off.
Is it possible to have the CH side of the combi drained and still get hot water?
If not what would be the best way to do this? I need to keep the house supplied with hot water whilst trying to avoid to much contaminated water from current system being run through the new rads (although not sure if that matters too much as would only be a few weeks).
thanks for any advice
Andy
