Our gas cooktop started playing up the other day. The thing lights as per usual but then the flames get smaller and smaller until it dies out. It does it on all elements. Its run from a 9Kg bottle outside the house piped in and has worked well since its install a couple of years a go. To me it looks like a regulator problem, even though it was new on install. Anything else it may be?

I agree. Enough gas left in the bottle to "pump up" the system and light the hob but not enough to keep gas flowing past the regulator.

This is what I am installing now. 4 burner with wok burner and a 9kg bottle. I envisioned a refill in around 3 / 4 months.

If the gas bottle is outside in the cold weather and frosts, the liquid can freeze in the cylinder and not evaporate into gas. Drawing gas from a cylinder will further chill it so it will light but slowly reduce in performance until the gas flow stops completely. Bring the cylinder into the warmth of the house between uses, build a heated cabinet around the cylinder, Get gas with a winter mix of less butane and more propane.

Butane and propane freeze at -140°C & -188°C respectively. This winter hasn't been that cold. :-)
I think what you are talking about is their boiling points which are -1°C & -42°C for butane and propane.
So if you have a frost outside the butane component of your LPG will cease to evaporate.

OK, we are in Auckland so its not that cold and the first thing i did when it played up was get the bottle filled. Tried another bottle too so its not the bottle.

We refill about every 5-6 months, only two of us here though.

It still could be the "new" bottle that has been filled, try purging the bottle, sometimes the bottle is not purged enough when it is filled

Have you thought about getting the gas guy or a plumber who does gas in to look at it?

It was the regulator as i thought. Took it to a combustion control and the guy took it out the back and gave it a quick test, then supplied me a new one that i fitted. Case closed.

Same here, we have gas in the motorhome and the wife loves it. So changing our home solid element hob to gas.

Very dangerous and illegal to enclose a gas bottle in a cabinet ,any cabinet must be well ventilated to the outside air . Thats why the bottle in a kitchen cupboard is now illegal unless the cupboard is well vented to the outside and has no electrical points in the cupboard .

an electric induction hob is as efficient as gas but you can not be killed by accidental leakage, best to do some homework before gas install as costs can be crippling. Lpg needs copper from bottle outside and natural gas will cost a dollar a day whether you use it or not for supply charge - go figure

What makes you think an LPG piping carcass need to be in copper?
Perhaps the user has a pacemaker and shouldn't be going near an induction hob.
