I assume the answer is no, but if this fixes the issue I know it will be what my builders sub contractor plumber will do.
Therefore, before he is allowed near the system I would like to either find the issue or eleimnate parts of the system that do nto have an issue.
As you will note from my post I am not a plumber, but I can follow basic to complex instructions. I assume plumber tested system but was not present when he left.
Situation:
New Viessmann Gas Boiler fitted a few months ago to a new build garden house
I turned on the heating for the first time last week. Three days about 3 to 5 hours each day.
Each morning the boiler had lost all pressure and had to be re-pressurised with the valve that loops form pipe D to E - see image
Following guidance from Viessmann (now closed for Christmas) I closed off all valves to the boiler after ensuting pressure was about 1.2 bar and left it overnight. Pressure has not dropped this morning.
Fairly sure that eliminates the boiler - would you agree?
Is there any possible fault other than a leak in the heating pipes?
There is no sign of water damage to any of the plasterboard - (timber frame building)
If there is a leak, will the pressure drop when I open one or more valves - without turning on the boiler.
A Heating Flow
D Cold Water
E Heating return
Will turning on one valve at a time help identify where the issue is?
Which valves? - then leave for a few hours or overnight? I assume A & E and order will make no diference.
As hot water does not have a valve am I right in assuming the leak must be in the radiator system.
Is there any chance of identifying a leak, with the boiler running, pointing a Laser temperature guage at the plasterboard walls?
Any comments of suggestions would be appreciated.
