.??? What are you on aboutSo a gas meter only registers legitimate gas usage?
Righto.
If the meter registered a gas leak, the leak would be quite large and there could be a danger of explosion

Righto.
An older boiler like this has the power input set by varying the gas supply pressure to the burner. The installer or servicer checks and if needed resets the pressure on the gas valve. The gas supply pressure from the meter is about 21 mbar and a typical burner pressure about 5 to 12 mbar so little scope for very wide misadjustment.
If the burner pressure is too high and if all the burner is lit then the additional heat is transferred into the system water so the additional power is not lost.
The one potential way for the gas not to be burnt is if part of the burner is not ignited fully. But that is unlikely as unburnt gas usually quickly lights if there is a flame nearby. That is about all the servicer could check and is very unlikely.
Read TFP it is not a modern boiler, it is a fixed rate boilerIs that even possible with modern boilers?
You do know piping can leak from any position in the system?
Who gives a **** if the joints are tight, its a system wide leak you would be looking for.
If you've unexplained gas usage, I'd be doing a system survey with a sniffer
Gas valve passing gas but no ignition.
Of course I do, hence why you would carry out a TIGHTNESS TEST,You do know piping can leak from any position in the system?
Yes, course you do
Give it a rest eh lol.
well how the feck can you test only joints ? you are so completely wrong, please go and bug some other poor people genuinely looking for proper advice rather than your deluded ramblings , this is a site where DIyers ask for advice, not for you to try and be a smart arseOk, well tightness test says to me its a joint test
So how would you approach the problem?And your point was caller ?
I would start with a tightness test, but I am a professional not a google warriorSo how would you approach the problem?
and if it is a top floor flat, do you absail down , or get a very big ladder, or do you follow the correct procedure for testing for gas valve let by ?You would detect the unburned gas coming from the flue, no?
I dont know what a "system wide, point-point test" is, I know what a tightness test is and I know what a let by test is, maybe you can enlighten me, I have been missing out on this point to point test all these yearsThat would be part of a system wide, point-point test wouldn't it?
Dunno, but mods are letting some threads run on and on (like Ariston - I’ll get my coat)Why are the Diyers arguing with Qualified Gas Engineers??
