# Gas Pipe

#### buildersbutt

Hi, have gas through 15mm pipe from meter to existing hob, the run from the meter to hob is about 5 meters, my question is we are buying a range double oven cooker with four rings, will the gas supply of 15mm be big enough. I also have a boiler and gas fire. Thanks for your time.

No.

Your RGI will be able to calculate the required pipe.

Your installation will require a pipe sizing calculation. From the limited info supplied though, it would seem to be already undersized.

A 6m length of 15mm copper pipe can deliver 1.9m3 of gas/hour.
Or enough for a 21kw cooker.
If you have a run straight for the meter to the cooker then
it can easily handle it assuming no other devices on that length of pipe.

Don't forget bends. Meter along from hob would have say 3 bends.... minimum.

Had a gas guy round and he said he would upgrade the exposed 15mm to the cooker to 22mm (about 2mtrs). So the boiler would stay on 15mm which is about 1.5 mtrs from meter, the fire is appro 4mtrs from meter. and the cooker is about 5mtrs from meter with about six bends on it!!

If you mean your point A to B offtake from the meter is 15mm, then your gas guy doesn't know how to do his job or the post is a wind up.

No it's not a wind up, I wasn't happy with what he said that's why I posted, he came recommended, LOL!!

post a little diagram of the piping and the kw of the appliances and we can calculate.

Where does your gas boiler fit in?
