Hi I wonder if anyone can help please.
I'm building a new small house and propose to install a natural gas kiln in an outbuilding.
The new house house will probably have a combi boiler 24-28kw & gas cooker hob (say 8kw).
I have no technical information of my kiln [25 yrs old] - manufacturer can provide NO support.
Looking at similar kilns and some previous experience its burners are rated at around 190,000Btu [55kw I think?] and would require a 7" water column pressure at full tilt.
So by my rough calcs - and I'm not an engineer of any description: kiln + gas combi+cooker= around 80kW- 90kW
The Meter box to be approx. 7m from the highway/gas main [4"main].
Total distance from Highway [via gas meter] to kiln shed approx. 27m
Propose to "t" off after the meter into say 32mm MDPe buried externally around the perimeter of new house to kiln shed - distance from gas meter to kiln shed approx. 20 metres. Is it permitted to use yellow gas mdpe pipe buried externally on the consumer side after gas meter?
Total distance from Highway [via gas meter] to kiln shed approx. 27m
Will probably request a 32mm incoming service from Cadent.
Is it ok for my groundwork contractor to buy & lay 32mm yellow mdpe for the 20metre length from meter to kiln shed? It was ok 30 yrs ago when I last had a gas kiln for builder to lay the yellow dupont (mdpe) pipe but regs may have changed. As said previously all gas connections etc by Registered Gas Engineer - we'd just lay the 20m of pipe & tape up the ends. I do remember that gas kilns need a larger supply pipe not just for demand but to act as a "reservoir" to compensate for a surge when the supply to the gas burners is increased to get the kiln to max. temperature around 1320C.
Thank you. Apologies if there is another post that covers this/similar.
All work would be done by a reg. Registered Gas Engineer - none appointed yet as only at DPC level placing external ducts/drains etc...
My Other option is to find a competent engineer to convert the burners to run off propane bottles and not bother messing with a 20m run of mdpe from meter to shed.
Thank you

- So will probably need a U16 Meter. Does that sound right *** anyone?
- Any thoughts on gas meter box size & suppliers ,ie future proofing for smart meter? [It will need to be a ground mounted box as no space for a recessed wall meter box]
- Does the incoming supply look reasonable or would you reckon I need 50mm mdpe service?
- Am I going to get a decent pressure at the kiln as its a long run at max. 27metres?
- Is the pressure going to be too high for a standard combi say an Ideal Logic+C24 (24Kw) / Viessmann Vitodens 100-W (26 kW )?
- Presume there's a method for the gas engineer to adjust the pressure at boiler to its operable limits?
