We went house hunting this weekend and saw this house which have a gas stove which I like however it is the first time that I saw were connected to those small bottles like you would normally see used in BBQ. Is this allowed? The other houses we saw have 2 of those big ones which I thought is the norm?

Hi, yes this is allowed, but as with any gas installation it must meet all the installation critera. We had this setup in a past house, a 9kg bottle with a hose through the wall to a 900mm Gas hob/Electric Oven setup. Typically would last 6-8months of normal use, when it ran out I just swapped over to the BBQ bottle and took the other to get filled.

The large pair of 45kg bottles are required if you have heating and an infinity califont also, but just a set of hobs, 9kg is fine

Bear in mind that if you wanted to upgrade to the big bottles (say if other appliances also ran off gas - which is against the rules but does happen) then it can be surprisingly expensive to move the regulator up the wall to accommodate taller bottles and have the system certified - best part of $500 I was advised by a gasfitter

Thanks. Based on the replies so far I think that is exactly why the current owners went with the 9kg ones as it is only the stove that uses gas. The water heater is electric.

If not using big 45kg bottles or mains gas I'd go for a 12kg bottle myself as there's less fuss in having them refilled or swapped less frequently than 9kg bottles require.

Hi, I understand that to have the bottle inside the house (as opposed to outside but behind the stove) is no longer legal, but I have not sited regulations regarding that, only based on what a gas fitter recently advised.

yes i know it's no longer legal, but it was put in like that (very difficult to use the word "install") in the 90s.

Our setup is exactly this, gas stove top, 9kg bottle outside. 6 to 8 months between refills. I keep a spare/BBQ bottle as well as running out when it's 7pm and half way through cooking dinner sucks.
It's a fine setup, no concerns.
Also, having a gas cook top is amazing. Recommended!

The old man's got this as well, installed in the early 90's. He's been advised he'd need to move it outside as and when he sells but he can leave it be for now. I think his plan will be to replace the hobs with electric.

Fond memories growing up of having to turn the gas valve on and off every time the hobs were used and having to do regular leak tests (dad rather paranoid having bottle in the house).

About 10 years ago I put in an oven with a gas hob. It was still legal then to have a 9kg bottle in a cupboard, but there were regulations about how it must be vented to the outside - to meet those regs was more hassle than the better and simpler solution of putting the gas bottle outside. (You'd need to cut holes through interior linings and exterior cladding to fit vents etc - vs running some soft copper gas line which looks like it's about 1/2 " diameter).

IIRC there was a cutoff point which was 15kg maximum storage capacity for a connected system - above that and the regs were far more stringent for placement of the cylinders. Where we've got the bottle installed it wouldn't have been possible to put a 2x45kg system - it's either too close to gully trap, to a sub-floor vent, to a window, or to a door - but no problems with meeting regs in that position for a 9kg bottle.

At that time I was able to get a copy of the regs from the (Chch) council website. Any gasfitter should be able to tell you.

Wow. We must do a lot of cooking. We get 3-4 months on our 9kg bottle connected to the hob (also out the back through the wall).

Same - about 4 months per 9kg. We probably do a lot of cooking (we = "me" - chief cook and bottlewasher). Also use a kettle on the hob rather than an electric kettle, unless the espresso machine is on.
