Hello, I have an open vented boiler with a gravity hot water circuit and a pumped central heating circuit.
I want to drain the central heating system to remove a radiator and give the system a flush.
Will the gravity hot water part of the boiler still work as I intend to leave the central heating side unfilled for a few weeks.
