What’s the best gas water heater?

It depends on the size of your home and how you tend to use hot water. Gas water heaters come in two types:

•Continuous Flow – compact and wall-mounted, this type heats water as you use it, delivering hot water that ‘never runs out’

•Gas Storage – this type heats the water and stores it ready for use, supplying it at mains pressure, so you can run several taps or showers at once without loss of pressure.

Have a look at our Water Heater Selector to find the right AquaMAX hot water system for you.


Can I install a gas water heater if I haven’t had one before?

If you have gas piping in your street, your home can be connected to natural gas. Your local energy provider can advise if gas is available, and arrange connection. If gas is not available, you can install a propane (also known as LPG) gas water heater, which can be run from refillable gas bottles.  A plumber will be able to advice of the work and costs involved.


What is Mains Pressure?

AquaMAX Mains Pressure water heaters heat water and store it so that it's ready for you as soon as you need it. This ensures full pressure to showers, washing machines, dishwashers, baths and basins - all at the same time.

It's important to consider this because everyone loves lots of hot water and no one likes their shower turning to a trickle when another tap is turned on!

I already have natural gas connected for cooking. Can I replace my electric water heater with a gas model and use the existing piping?

It will depend on the size of your existing gas pipe, and the type of gas water heater you want to install. Most gas storage water heaters can be fitted to the gas pipe that already exists in many houses, but a continuous-flow water heater requires a larger diameter pipe to be installed from the gas meter.

What does First Hour Delivery mean?

First Hour Delivery (or sometimes called first hour rating) is a term that describes the performance capability of the water heater. By definition, first hour delivery is the calculated amount of hot water a fully heated water heater can deliver in the first hour period. This means you start with a water heater that has recovered to its’ thermostat setting (fully heated) and someone starts to use hot water such as in a shower.

What is Peak and Off Peak?

Off-peak refers to lower, discounted electricity prices during specific times.  Off-peak times are generally when residential homes and businesses use less electricity.  Off-peak times will vary depending on your location and meter type, but typically are at night and/or weekends. Peak times are normally during the day, from 8am - 8 pm when electricity is used the most. If you have an electric water heater, you can reduce your electricity bills by using hot water at off-peak times whenever possible.

How do I choose the best water heater for me?

When choosing a water heater, you should consider:

·         How many people use hot water in your home

·         How many bathrooms

·         Usage level

·         Electric or Gas/(LPG)

By answering these questions, our Water Heater Selector will help you determine the most suitable water heater.

Can I install an AquaMAX water heater myself?

No. Only suitably qualified plumber/gasfitters are permitted to install gas hot water heaters. The installing plumber/gasfitter is qualified to install and commission gas appliances, and is able to advice on the operations of the gas appliance upon completion of the installation. The installer is authorized to issue a Certificate of Compliance at the completion of the installation. If an AquaMAX water heater is not installed by a licensed plumber, it will not be covered in any way by warranty.


Is a Certificate of Compliance required for all installations of an AquaMAX water heater?

In most situations a Certificate of Compliance is required. The installer will be aware of any additional state- based plumbing regulations which affect the installation.
