Hi,
I have a oil combi central heating system with a indirect cylinder. The heating system works fine. With just the water turned on the top feed pipe into the cylinder gets really hot quick enough but the bottom pipe is cold. I have to bleed through the pump around every 20mins and after 3hrs I might get look warm water. I cannot turn the heating on at same time or I won't get any warm water as it seems to take pressure away, as it won't bleed out pump and top feed pipe goes from really hot to warm. Some air gets into the radiators as I need to bleed the bathroom every fortnight. Suspect as its a combi system then air getting into heating system from water system. This has been like this for years. Suspect either internal leak in cylinder but water out taps not dirty. Or underground leak but thought I would still see leak after all this time. Any suggestions
Thanks
