FAQ • Frequently Asked Questions for LPG Gas
How do I operate a home LPG gas system?
Please see information you need to know if you are a New User of Home LPG
How do I add LPG to my all-electric NZ home?
To add LPG to your home, you engage a licensed gas fitter to install the gas regulator, changeover valve and the “pigtails”.
The gas fitter also connects the gas line from the regulator to your appliance(s).
These components and the appliances are your property.
Please see How To Add LPG Gas to Your Home for more details
The cost of the installation includes regulator, valve, pigtails, the gas line to the appliances and the cost of the gas fitter's labour.
The cost will vary by the length of the gas line required between the regulator and the appliances and the individual gas fitter.
You do not need to buy the gas bottles.
Elgas owns and provides the gas bottles.

How is my home LPG delivered?
Elgas has two methods of delivering LPG to your home:
1. Automatic Tanker Delivery: Exclusive to Elgas, EasyGas™ automatic tanker delivery involves delivery via state of the art tankers, which refill your cylinders on site.
You won't have to remember to order LPG and there's no more replacement of cylinders.
Elgas monitors your usage and schedules regular tanker deliveries to suit your needs.
2. Cylinder Exchange Delivery: In cases where we are unable to deliver via tanker, we deliver cylinders to your home.
Ideally, with two cylinders connected, we're able to replace one, when empty, ensuring you always have enough supply.

Is LPG dangerous?
If used and handled in accordance with prescribed procedures LPG is safe.
As with electricity, natural gas, petroleum and other household chemicals, care should always be taken when using LPG.
Elgas has established an unrivalled reputation for safety, from regular compliance checks of your cylinders to the comprehensive safety and maintenance schedule of our tankers.
Why do gas bottles have to remain upright?
Gas bottles must be used and stored upright for safety reasons.
All home and BBQ gas bottles are fitted with pressure relief valves, which are designed to safely release gas in the event that the gas bottle becomes hot and the pressure becomes too great.
The pressure relief valves are incorporated into the main valve, which is at the top of the bottle.
Inside the bottle, the LPG exists as liquid at the bottom and gas vapour at the top.
Keeping the bottle upright ensures that the safety valve is not immersed in the liquid and is located in the vapour space, as it is not designed to vent liquid.
Where do I find an MSDS for LPG?
Why is the price of LPG Autogas lower than my LPG for my home?
The pricing is mainly based on the volume used.
Service stations purchase their LPG in large volumes, storing up to 65,000 litres at a time and refilling frequently.
The cost of delivery is also VERY different.
With Autogas, we can deliver an entire tanker full of gas within a couple of hours.
With home delivery, that same amount of gas could take many days to deliver.
Also, remember that with Autogas, you go to the gas and you provide the labour to fill your tank instead of having the gas brought to your home and having someone else do the filling.
Why does the price of LPG vary from time to time?
The price of LPG varies on a monthly basis based on a range of international and local market factors.

What is LPG?
What is the difference between LPG and natural gas?
They are similar in terms of usage.
However, LPG produces greater heat due to its higher calorific value.
Is LPG used to fuel motor vehicles?
Yes, but it's a blend of Propane and Butane commonly known as LPG Autogas.
Is LPG the gas used in NZ barbecues?
Yes. It's also used in space heaters, water heating systems, cookers and other applications.
Can I use LPG in natural gas appliances or vice-versa?
No. Each type of gas requires different amounts of oxygen to burn properly, so different burners are needed in the appliances.
All gas installations and conversions must be carried out by a licensed gasfitter.
