New Install

[jefaz]

Evening folks,
Just a quick one. I've been asked about installing a boiler into a church hall,the room has a floor standing domestic boiler and a main water heater,both are to be pulled out and replaced with a combi.
i believe the gas meter however is commercial as there is a commercial boiler that runs the church part
sp my question is am i able to install this boiler or do i need to get someone with a commercial ticket to do the gas and i can do the rest?
any help appreciated!!

Does this not depend on the size of the gas pipe...

 

[southcoastboile]

Wont you have to tap into the existing commercial pipework to run the new boiler pipework?

 

[grahamgas]

What size is the meter at the moment?

 

[hammers4spanner]

What size is pipework coming off the meter as it is now?

 

[jefaz]

thanks for the replies ......... meter is maybe a g25 or summit although i could have dreamed this up!
off the gas meter im not sure either but its bigger than 28.
the feed to the boiler in hall is 22mm

 

[hammers4spanner]

domestic is 35 mm i think

 

[grahamgas]

Domestic is:
up to 35mm pipework
up to 70kw
U16 meter max
Pipe volume no greater than 0.0035m3

A u16 meter has avolume of 0.0025m3.

So going from what you are saying then it does sound commercial territory.

cheers for the replies guys, i know the maximum pipe is around 35......so saying its 35 and the meter is this g25 or whatever am i able to cut in and work on it?

No as a g25 meter is 40 m3 an hour, way out of scope for domestic.

No but what you could do is to get someone to run the gas to the appliances, with an iso valve and test point, then you can work from that point on.

 

[jefaz]

not 100% if it is G25 but if it is ill leave well alone!
So are these domestic appliances classesd as commercial installs becasuse of this gas meter?

 

[jefaz]

an idea yes so assusme i got someone to do that how would i go about registering the install with gas safe? with the gas being commercial! its annoyong that these pipes are 22mm too

 

[grahamgas]

Had a debate with a gas safe inspector recently.
He said if mis refer to British standrads for domestic flueing and ventilation, then obviously domestic, if it refers to bs for commercial flue and vent, then obviously commercial.

I used to maintain a site a few years ago. It was a care facility with individual 6 person properties each with its own boiler. Everything was domestic except for the communal gas meter that was the size of a small planet. Every property had an ECV and test point at entry so I was able to treat each property as an individual domestic installation.
