I have got a typical gravity fed heating system with cold water and small header tanks in the loft, hot water cylinder, heating control, pump and 2-way valve in airing cupboard and back boiler and fire on chimney breast downstairs.
Today I drained the central heating system by removing a radiator downstairs, a lot of water came out. After capping off the pipes to the radiator that was removed I went back to the loft and to my surprise the header tank was still completely full. I don't think the water level moved one bit.
I want o refill the system but I don't know if it will be possible now. Any advice would be much appreciated. Thank you.
