How long for boiler to cool to check pressure

[Robert Anderson]

Hi guys really quick question I’m assuming if I’ve not had my heating on for 24 hrs n the boiler pressure is sitting at 1.4 bar which is what it was topped up to after service 3 weeks ago that’s its pressure at cold as in its resting pressure, suppose what I’m saying is after 24 hrs of no heating on is that a accurate time to check what the resting pressure is at?

I’d say that’s fair

Hi Riley, was just wondering. Just got this paranoia of boiler pressure dropping lol it was serviced 3 weeks ago n topped up to 1.4 after hearings been on say a hour or 2 if I check it 12 hours later it’s at 1.4 last week after 36 hours it was roughly the same n then yesterday heating went off at 6am n wasn’t back on till 5:30am this morning but I checked just before it came on n still at 1.4 so I’m assuming all good, I take it say I was away a few days or a week would I expect it to settle a little lower should no heating hot water being used? In summer like

I generally tell my customers that they should have to top up the pressure a couple of times a year. Usually when the cold kicks in and then subsequently when the hot weather first starts. Some do some don’t but it is all down to expansion and contraction of the system.

Cool thanks again amigo much appreciate I actually did notice when nice weather at Easter it say slightly over the 1.4 but when got cooler again back down, im assuming by topping up you mean if it’s down below one or greater then again in winter then

Also if it was dripping say 0.1 Barr over 2-3 months would that be kind of normal too

Dropping not dripping

 

[Robert Anderson]

Sorry all the questions just so I don’t panic if it does drop a little

 

[Riley]

Dropping a little can just be down to atmospheric change. Dropping to the point when the boiler won’t fire I’d be concerned

Yeh I mean say 0.4-5 bar over 12 months type thing
