Want to freshen up the heating system in the house, as moved in last year and unsure when it was done last.
Now its a combi, ive never drained a combi before just the normal feed and expansion, i isolated the water feed to the boiler and found two drain plugs under my side door floor mat in the house which must be for the heating and maybe the water pipework for the house, now i open them and nothing , turn the water on and one flows so that must be the water pipework, is there anything at the boiler end you have to open or fiddle with as i've never had a combi before.
thanks in advance.
