What are the Benefits of Gas?
Who’d have thought a small, pure blue flame could have such a positive impact on our lives? Yet that’s the very beauty of gas. Gas is energy in an instant. Instant heat to warm your home, copious hot water, more efficient cooking and extended use of your outdoor entertainment areas.

If you want to cook like a chef, there’s no substitute for the intense, controllable heat of gas. If you want to enjoy more warmth and luxury in your home, gas is the answer.

Is gas a smarter choice for home heating than electrical heat pumps?
Many people are promoting electrical heat pump units, however with simple mathematics it can be shown that utilising natural gas as a source of home heating can be far more economical, this can be done by comparing electricity and gas prices/kw. Currently gas prices are around 7 cents/kw and electricity prices vary but are about 27 cent/kw.  This means a heat pump would have to be operating at about 385% efficiency at all times, with the majority of heat pumps this is not possible. (especially as the outside temperature decreases)

Even taking into account that some gas heaters operate at about 80% effficiency an electrical heat pum would still have to attain a constant 308% efficiency which is not realistic for the majority of heat pumps (especially below 15degrees which is when heating is generally required.

With the introduction of the electric smart meter it is also expected that home electrical costs will rise, a further incentive to utilise gas as a source for home heating + hot water.

We are currently planning to build a house, should we be planning gas with this process?
Yes, This is the best time to get gas installed.

How long does it take to connect to gas?
LPG This is the quickest form of connection, the only delays being, LPG cylinder & appliance delivery and gas fitter availability.Natural Gas – From the time you’ve signed up, connection usually takes 4-6 weeks

If I connect to natural Gas, won’t my driveway or section be dug up?
To connect the gas from the street to your house, usually an underground thrusting or drilling machine is used, or a small trench may be dug and then backfilled ensuring that every effort is taken to restore your property to its previous state.

Is Gas Cheaper or more expensive than electricity?
It all depends on what gas and electric appliances you use and how efficient they are. In general, however, a dual fuel household (combination of gas & electricity) is more energy efficient than a household using only electricity.

Should I worry that there’ll be no gas for my home when the Maui gas field runs out?
No, there is nothing to worry about. The domestic load is relatively small, so there will be plenty of gas for the domestic market for the foreseeable future. There are new gas streams coming on line that will assure the continuation of the supply to the domestic market

One of the selling points of gas is that it’s cheaper than electricity. Will gas become more expensive than electricity?
Unlikely. It’s more likely that gas will continue to be cheaper than electricity. Gas used to heat directly is more efficient than gas-fired electricity, so gas has the advantage of producing more heat at less cost compared with electricity. Some people say they pay more for their gas-heated hot water but that’s because the water’s always hot, so they stay in the shower for longer. With instantaneous gas water heating everyone in the family can take a 10-minute – or longer – shower. If they tried that with water from an electric hot water cylinder, they’d be out of the shower sooner because the water would start running cold. If the gas bill is higher that’s because you’re using more gas to enjoy the luxury of hot water that’s always on tap. A fair comparison would be if both families stayed in the shower for the same amount of time – and in that case the gas bill would be a lot cheaper.

Can I be sure that switching to gas can be justified long term?
Of course you can. As mentioned above, there is sufficient gas now and new finds coming on stream will ensure that switching to gas is a good way to go. Gas is an environmentally good choice and is being seen as the fuel of the future.

Gas labels and marks

When used for a gas appliance, this label/mark is called the Gas Safety Compliance label, and when used for gas installation work it is called the Gas Authentication Mark. The Regulations require all gas appliances to be labelled with this gas safety compliance label.
