How do I check how much gas is left in my LPG bottle?

When your LPG appliances are operating, a line of condensation should appear at the level of the remaining gas. If no line is apparent, run your hand down the bottle and it will feel cold at the level of gas.

Why do I have more than one 45kg LPG bottle?

One bottle provides the main supply and the other provides extra gas when needed due to increased demand from your appliances. It’s important that all cylinders are left turned on for your appliances to work efficiently.

Even though both bottles are turned on, you will not run out of gas any quicker, as your appliance will not continuously draw gas from both bottles.

What do I do if an LPG appliance doesn’t work?

Firstly, check the regulator on top of the bottles to see if your bottles are empty. If there’s still gas in at least one of the bottles, check your appliances for basic errors such as a pilot light having gone off. If there’s no obvious explanation, call your gas fitter.


How do I know when to re-order bottles?

The regulator on top of your bottles will have a red indicator or red flag when a bottle has become empty.


Autochange regulator

Autochange regulators use a visual indicator to advise you when a bottle has become empty and has switched over to draw gas from the other bottle.

While some indicators start off green and others clear, they all turn red when the bottle is empty. Do not touch or turn the dial. When you see it turn red, that’s your signal to call Genesis Energy for a refill delivery. We will pick up the empty bottle and replace it with a full one, and reset the regulator.

Manual regulator

If your bottle station has a “manual” regulator, you will need to turn on the valve on your reserve bottle once the first bottle is empty. Gas is then drawn from the reserve bottle.

How do I order bottles?

You can order refill bottles by calling 0800 300 400 or requesting a refill online at genesisenergy.co.nz/lpg. A full bottle will be delivered within six working days. Make sure you have your LPG consumer number handy when you place the order. If you require an urgent delivery, an extra fee is payable in addition to the standard delivery charge. Please contact us to confirm time and costs for urgent delivery.

How do I avoid problems with LPG delivery?

Please make sure trees are trimmed for the delivery truck, the access way is clear, and the ground is firm and non-slippery as the bottles are heavy. You don’t need to be at home for the delivery but if you have any potential delivery issues like dogs or locked gates, please provide us with this information. Deliveries will not be made if there is a health and safety risk to the delivery drivers.

How do I know that my LPG bottle has been delivered?

When a bottle has been delivered there will be a delivery card left in your letterbox or on your bottles telling you when and home many bottles have been delivered.

For any other LPG questions, please call 0800 300 400.
