System pressure loss

Mods, I didn't realise CHK was a forum sponsor or can we all freely advertise our wares so openly? Well ok then, maybe Yorky Dave was allowed with his magic tap dancing shoes.

Key word temporary

How many are getting left on / in and no ones finding the leak / problem

Agree with this statement mate.

Just thought I would post an outcome.
I was worried about running the boiler with the system valves closed so just disconnected condensate drain, connected it to a receptacle and left the boiler pressurised to 2.5 atmospheres. Over 6 hours there was a tiny pressure drop and a small drain of water. Repeated the process and this time no drop, no leak. I still felt it was likely the HE was leaking, probably most noticeable when hot, so from advice here thought I would give Ideal a try.
I don't quite understand the system, but with 300 quid over 6 months through domestic and general they would repair any fault on the boiler and guarantee it for the 6 months.
So decided to go with this. Engineer sent next day, stripped boiler, to my relief showed me the knackered HE and replaced it, with a general clean. Apparently the 300 quid is the cost of repair whatever it is, minor or major, so I presume d&g hope we will forget to cancel at 6 months and carry on with some exorbitant contract, note to diary.
In all I am very happy to have the 300 quid fix on an 8 year old boiler which in other respects has functioned well.

Lastly, sorry to have stimulated some flaming over the leak replenishment system: from an amateur viewpoint I would only like one fitted if it was able to give some indication of excessive replenishment or there could be masking of a fault and possible dilution of inhibitor

Glad you had it fixed and thanks for the update

As above, glad you have it fixed, if the expansion vessel pre charge and filling pressures have been done properly by the installer then you will have indication of any leakage.
