Topic: How to bleed heating system
July 24, 2019 / By Brutus Question:
I drained down my central heating to change the TRV's. When I refilled it the boiler will not come on. It is the type with a primary and secondary circuit that also heats my water. There is still a lot of air in the system and I have been constantly bleeding each radiator in turn. It is because there is still too much air in the system or should I be looking for something else?
