The possibilities

Water that costs you less but is always hot

For most of us, hot water is the number one reason to get gas. It’s a really effective way to heat water for your home and could cost you less than heating it with electricity – especially if you have an old, inefficient cylinder or if you’re already using natural gas at home.  

Many people choose continuous flow hot water so the shower will always be hot when it’s your turn. But more than that, the performance is outstanding and the efficiency, high. Some appliances promote 95% efficiency with 7 star rating, so they’ll cost less to run. Interested in gas-powered hot water systems to complement your bathroom set up? Head over to our appliance gallery and get inspired.

Love endless hot water

Natural gas-powered continuous flow hot water is efficient and affordable, and the water is heated as you use it so you pay for what you use. It’s ready on-demand right when you need it and never runs out, unlike a cylinder. That means there’s always enough water for everyone to enjoy a long, hot shower or a soak in the bath. 

Often called ‘instant hot water’ or ‘infinity hot water’, a continuous flow gas hot water system is a powerful and practical home improvement option that does not require a big budget. Expect to pay around $2,300-$3,800 for the system installed and ready to go (costs indicative and dependent on appliance choice and home layout). A gasfitter can give you a free quote for the ideal hot water system and installation at your home.

Great benefits of continuous hot water for the family include being able to control the temperature of your hot water and set it – with the push of a button on your deluxe controller – to a temperature that’s safe and comfortable. Switching to continuous is very practical choice for saving space because the unit is compact, and generally is mounted externally outside your house. This frees up valuable space inside.

Stylish, modern bathroom

Great gas cylinders

You’ll love your bathroom more with gas hot water heating. The main benefit of choosing a gas hot water cylinder is that some models will still work in the middle of a power cut. 

Natural gas cylinders come with different storage capacity, allowing you to get a size appropriate for your household. Cylinders can be flexible to suit both mains and low pressure water, and there are models that can be installed internally and externally. Let the experts determine what size cylinder is best for your household. Rheem is a major manufacturer of natural gas hot water cylinders in New Zealand. 

Rooftop solar panel

Gas and solar together

With solar, sadly your energy source disappears with the setting sun, and batteries to store solar power are still fairly expensive. It’s worth thinking about your household situation when sizing up hot water systems. 

If you have a busy household with heavy hot water demand, solar works well with a secondary power source like natural gas. Natural gas to boost your solar system is a great back up option and many gas continuous hot water systems are solar-compatible, so you can ensure when the sun loses its heat your hot water won’t.
