In New Zealand, we tend to rely on two types of gas for our household energy needs: natural gas and liquid petroleum gas (LPG).
If you are interested in bottled gas but are unsure whether it is right for you, read on.
What is LPG Bottled Gas?
‘LPG' is actually a catch-all term for a number of different types of gas. The common characteristic of these gases is that they can be compressed into liquid. Butane and Propane are the two most common types of gas in the LPG category.
Bottled vs. Natural Gas
Bottled and Natural gas generally satisfy many of the same household energy requirements but there are differences between the two.
Most homes in NZ that use bottled gas use a Propane-Butane mix.
This type of gas is supplied in gas bottles and goes by many names: LPG, LPG gas, LP Gas, BBQ Gas and bottled gas. Regardless of the name it goes by, it's all the same gas.
For the most part, people opt for bottled gas in the home when natural gas is unavailable or too difficult or uneconomical to install.
- A cost-effective gas solution for households without access to natural gas.
- Available in more areas than natural gas.
- Whilst easy to manage, gas bottles still need to be monitored and refilled/exchanged.
Natural gas differs from bottled gas in that it is piped direct to the home via gas mains.
Natural gas is primarily Methane and is often referred to as "Mains gas" or "Piped gas". This is the method by which most NZ households receive their gas.
- Gas is via the mains so you don't need to manage your supply.
- Not available in all areas of New Zealand.
What size gas bottle do I need?
Gas bottles come in a variety of sizes based on their weight. The heavier the bottle, the higher volume of gas bottle.
Generally, gas bottle sizes are:
* At Genesis Energy, we only provide 45kg gas bottles to bottled gas customers.
How long does a 45kg LPG gas bottle last?

|Home heating only||6-9|
|Hot water 2 people||4-6|
|Hot water 4 people||6-9|
|Hot water 6 people||9-12|
How to tell if your gas bottle is empty?
Most households will run off two gas bottles at at time so you have a backup when one runs empty offering an uninterrupted supply.
You need to check the indicator on a regular basis to see if it is empty.
TIP 1: If you use your bottled gas for heating, make sure you check every second day during winter.
TIP 2: Sometimes, the indicator will dip into the red but then go back to green or black usually when there are a lot of appliances drawing from the bottle at the same time. So, check the indicator without any appliances on 12 hrs after it turned red.
If it's still red after then you need to order a refill.
How to refill your gas bottle
Gas bottles for household use are too large to take to a refilling station (unlike 9kg bottles used for barbecues etc.) When your gas bottle is empty, you will need to arrange for your bottled gas provider to refill it for you.
Genesis Energy customers can order bottle refills online, via the Genesis Energy Mobile App or by phone. We'll deliver a full bottle in around four working days, excluding weekends and public holidays.
