As above, with an unvented hot water system, I thought the hot water pressure should be the same mains pressure as the cold. It’s not - I’d say it was about 75% of the pressure. Can it be adjusted anywhere?
Yes, sorry. I think I meant flow rate. Can anything be adjusted or shall I just leave it alone - it’s not a major problem, I think I’ve just noticed it because I’ve changed my bath and basin taps.Do you actually mean pressure or do you mean flow rate ? they are not the same thing
Air is released from the water easyer when its hot, see it on combis all the time between it being hot and having went through a turbulent flow. its nothing to worry about, its in the cold too just dissolved so you cant see itJust another question: When filling a glass of water from the cold tap in my basin, it’s gin clear. When filling a glass from the hot tap, it looks chalky but on closer inspection it’s tiny air bubbles that clear in about a minute. Any idea what’s causing this?
If the cold is running higher than the hot unvented then the cold supply probably hasn't been piped from the combi valve, it'll be fed directly from the incoming mains (Before the reducing valve)
Sorry, no idea on that.Do you know what your cold mains dynamic pressure and flow is?
