Making the connection to LPG

So you’ve decided to make the switch to gas but find out after hours of research that your home cannot be connected to the natural gas network. All is not lost as Liquefied Petroleum Gas (commonly known as LPG) in most cases is still a viable alternative to electricity.    

There are also many misconceptions about connecting to LPG however in the majority of cases the process is relatively straight forward.  As long as you have enough space externally to safely install your LPG cylinders then you should be able to utilise LPG.  There are also a large number of retailers and trade professionals that can assist with getting you up and running.    

Here’s a four step approach of how to get connected to LPG:


Step 1: Decide what appliances you want connected

First off you will need to choose what gas appliances you want to connect up to your LPG supply.  This may include a Rinnai INFINITY® continuous flow gas hot water system, a gas fire, gas heater and/or a gas cooker.  The number of appliances you want connected will affect how many LPG cylinders that you require and in some cases you may need a location test certificate to legally store these on your premises.  An energy retailer should be able to recommend how you can obtain this certification or you can consult Worksafe New Zealand for more information.   

Step 2: Contact a gas fitter

A licensed gasfitter is needed to safely install your LPG cylinders and connect them to your selected appliances.  They can provide a quote to connect your appliances to your LPG cylinders, and can help you choose a compliant location for the LPG cylinders.

Step 3: Set up an account with an LPG supplier

There are lots of options here, from large energy retailers such as Nova, Contact and Genesis Energy to smaller more local providers such as Elgas.  Websites such as can be a useful resource in making your decision.    

You will need an account with that retailer for billing purposes and typically they will ask you the name of your gas fitter.    

You will also need to pick your LPG supplier before the gas fitter starts, as they will need to know who to order the initial gas bottles from.

Lastly you need to decide on the type of gas bottle delivery that you want.  Depending on where you live in New Zealand, there are normally two options to choose from, Automatic Tanker Delivery (your retailer monitors your usage and schedules deliveries) or Bottle Exchange (you will need to monitor and reorder any replacements yourself – sometimes this is as easy as ordering via a mobile app). 

Step 4: Installation

After you’ve sorted the above, your gas fitter makes all the necessary connections around your property and between your appliances.

Once you’re connected, your supply will automatically switch to your next LPG cylinder once you’ve used up your first.  The option you chose for gas bottle delivery then takes care of future supply. 

And there you have it, you’re connected and will soon be enjoying the benefits of LPG.

We are going to be changing to our hot water heated by gas. Our fitter has suggested to also look at a small gas heater for our basement which is being renovated to a studio flat. Do we need to get council consent for this heater and flue as you would for a wood burner?

Hi Karyn

Different councils require different information, you will need to check with them what they require, usually if it is a heater like our EnergySaver range then it is not required, but if it is a Gas flame fire, then some council require consent. We have all the product technical statements on our website for easy of application.
