Acceptable gas pressure drop between meter and boiler?

Is the drop on the new pipework?? If so then it is not acceptable.

You are allowed 0 on new gas runs.

17 m/bar at boiler i would of thought it is slightly undergassed.

Manufacturers generally state 20 m/bar, does it require 20 m/bar in your manual??

Are the burner operating pressures correct? If not boiler may be undergassed.

This could be due to gas coming in to the house is not suffice or wrongly sized pipework. Has he replaced all of it in 22mm?

You could do with it being checked out!!

Hope that helps.

 

Also how do you know the drop is between boiler and meter, has he capped off other gas legs and re tested to know this is the case?

 

Both mate!!

What area are you in??

There maybe some lads on here that will sort it for you.

 

+ or - 1mbar,with all appliances on. Think others are talking about tightness test,ie carcassing

 

I am presuming he did a tightness test before he started and then after.

If there was no drop before and then 3 afterwards then it's on the new run most likely.

 

Just noticed screwhard post, can you clarify whether it's gas leak or loss of pressure?

 

Aah right i was thinking leak sorry.

Nice one screwhard for clearing it up.

If the governors been changed, and your getting the required pressure coming in, and you still have good pressure at the meter with appliances on it's down to pipe sizing mate.

 

Although the problem should of come to light straight away when commissioning the boiler.

 

You need it checking at the boiler now to make sure.

 

If you can follow the pipework from meter to boiler and check that it is all in big pipe and no small pieces of 15mm etc where it has not been changed.

Good choice of boiler though!!

 

Get the installer to check boiler burner rate when in domestic mode, when other appliances are running.Also you say thegas supply starts at 25mm i think you mean 28mm thats what it should be,do you mean the bends are elbow fittings would be better if they were bends less resistence.
