Hi all,
Really hoping someone can provide some suggestions.
We have an Ideal Logic Heat 15 boiler and a Range Tribune HW cylinder all on a sealed heating system. The pressure gauge is up in the airing cupboard with the cylinder and the boiler is downstairs.
When I first turned the heating on one radiator was full of air so I bled it and topped up the system to 1 bar. Six weeks ago the pressure had dropped a bit and there was more air so I did the same.
I found a radiator where the bleed valve was loose so I tightened that up.
Since then the pressure dropped to 0.8 bar, but all radiators were roasting hot so I don't think they had air in.
Last weekend (without bleeding anything) I topped the pressure back up to 1.0 bar, but this weekend it is back down to 0.9.
So to summarise:
I'm losing about 0.1 bar a week.
I have no visible leaks.
I don't seem to have air in the radiators
Nothing is dripping from the tundish
The pressure never seems to go lower than 0.8 bar
One interesting thing Is regardless of whether the pressure is 0.8 or 1.0 cold it never gets above 1.3 when hot.
Does anyone have any suggestions before I get the professionals in? Or is this just normal?
Many thanks.
