What is Natural Gas?

Gas is commonly referred to as ‘natural gas’ as it’s a naturally occurring gaseous hydrocarbon (a molecule made of hydrogen and carbon atoms). It consists mainly of methane - the simplest hydrocarbon.

Gas can be used for heating, hot water, cooking and outdoor living.

What is the difference between Natural Gas and LPG?

Natural gas cannot be stored and transported as a liquid and therefore is not widely available (only available in the North Island). In addition, LPG produces greater heat due to its higher calorific value.

If I am on the All Energy Plan, is my plan price protected?

Only the electricity portion of your All Energy Plan is protected. If you wish to switch to another electricity retailer, you will need to provide us with 30 days’ notice or a $150 termination fee will apply on your residential electricity account only.

Can I use LPG for Natural gas appliances or vice-versa?

No. It is important to not use LPG for Natural Gas appliances and vice versa, as each type of gas requires different amounts of oxygen to burn properly, so different burners or jets are needed in the appliances.

Is gas safe?

Yes. As long as the installation and appliances are up to standard. Your appliances need to be serviced regularly to ensure maximum performance and safety.

Your safety around gas is very important. If you suspect your gas supply or appliances are faulty or leaking (even if you are not able to smell gas), turn off your gas supply immediately and contact a registered gas fitter.

In the case of an emergency dial 111.

As with electricity, and many other household products such as cleaning chemicals, care should always be taken when using either Natural Gas or LPG. Refer to our Living Safely with Gas section for more information.

How much does it cost to run my appliances?

Appliance costs vary significantly, and usually depend on the brand and features of the appliance. This information can be obtained from your local appliance retailer. Gas appliances are efficient and are usually cheaper to operate in the long term.

For safety reasons, no. If you want to be supplied by Grey Power Electricity LPG you need to rent Grey Power Electricity cylinders. This is because the LPG cylinders we provide are subject to strict maintenance and safety checks as required by law.

What do I do if the gas appliance (heater, stove, etc.) doesn’t work?

Check the regulator on top of the cylinders to see if all parts are red. You may need to order a new cylinder. If both cylinders are empty, and an emergency or urgent delivery is required there may be an extra charge for the unscheduled delivery. If the regulator indicates there’s still gas in a least one of the cylinders, check for basic errors such as a pilot light having gone out. If there’s no obvious explanation, call a registered gasfitter (from the yellow pages) to check your appliances.

If I am organising a new connection, how will this be done?

If you’re adding bottled gas to your home for the first time, you will require a gasfitter to install and connect the system. Safety regulations require that once OnGas has delivered the cylinders, the gasfitter will need to return to the property to connect the installation to the gas supply (cylinders) and turn the gas on.

Apart from the gasfitter’s time and materials (eg. pipework), there are some initial set up costs for your cylinder station which will also be incurred from your gasfitter. These are items such as the concrete pavers to place the cylinders on, chain set, regulator, regulator cover and hoses.
