Guide to Buying Heating: Part 2 Choose the Best Heater

Choose the Best Heater for You

If you’re struggling to choose heating for your home, you’re not alone. Most people understand that choosing a system to suit their home and lifestyle will be more cost effective, but what they often don’t know is how to evaluate which is best. Part 1  of the Heating Buying Guide gave an overview of the types of heaters in Australia and their prices. This second and final part looks at important considerations when buying a heater, so you can choose the best heater for you.

Installation and Flues

Depending on where you buy your heater, installation and flues (if applicable) may or may not be included in the price. Since these items can add significantly to the purchase price, we recommend you have them priced before you buy the heater.


Australia has stringent safety regulations on all heaters sold and their installation. It is important that you comply with safety instructions in the manual provided with your heater and hire a licensed professional to install your system properly.

Using Gas as a Heating Source

Mains gas (natural gas) is generally cheaper than electricity. Since this price can vary, you should check the providers’ pricing in your area.

The prices in Part 1 assume you have mains gas of sufficient pressure to operate the heater. If you don’t, a licensed gas plumber will need to install suitable pipework. The cost of installing pipework can be significant, so make sure you get a quote for this work before you buy your heater.

Mains gas is not available to all homes, but that doesn’t mean you can’t have a gas heater. If your home doesn’t have mains gas you can opt for bottled liquid petroleum gas (LPG) instead. Generally, we don’t advise using LPG as a primary heat source because it is relatively expensive and you have to deal with the hassle of running out of gas frequently. Talk to your local supplier if you have any questions about installing a gas heater in your home.

Radiant vs Convector Heaters

Convector gas heater

Most heaters on the market are either radiant or convector (convection) heaters.

The advantages of a gas convector over a radiant (space) heater are that it:

The disadvantages are that convectors cost more to buy than radiant heaters and also require an electrical outlet to power the fan.

Radiant convectors are a hybrid between radiant and convector heaters and are priced in between the two models. The disadvantages of this type include traditional styling, the need for an electric outlet and not having as many features as a convector.

Running Cost and Efficiency

Heaters run for extended periods so it is important to keep your running cost low by choosing a heater with a high efficiency rate. There is usually a trade off between low running cost and higher purchase price because of the more complex design in highly efficient heaters. To find out the running cost of a particular model ask your local retailer.

Other important efficiency factors to keep in mind:

Popular Features

Timers are very popular because they let you set and forget. Who doesn’t want to wake up to a warmed room on a cold winter morning? Multiple fan speeds, a child lock and remote controller are also popular.
Some air conditioning controllers, such as iZone and SKYFi, let you use your smart phone or tablet operate your air conditioner.

If you are paying extra for features be certain you are going to make good use of them.

Heater Life and Warranty

Buying a cheap heater may be a false economy if it needs replacing after only a few years. Undersizing your heater will mean it will have to work harder and generally won’t last as long as it should.

Invest in a quality heater that lasts longer and costs a lot less to run. A good indication of system quality is warranty coverage, claims frequency and waiting periods. Also ask the supplier for details of the installation warranty (installers and gas plumbers who are sourced independently may not warrant their work).

Environmental Efficiency

Environmental efficiency is about reducing emissions and environmental impact in order to protect and sustain our environment. The Australian government provides an overview of the environmental efficiency of heaters on their energy efficient home design website. According to their data, gas is a more environmentally efficient heat source than electricity generated from coal power stations.

We hope this guide has given you a better understanding of your heating options and helps you find a suitable choice that will last.
