How to choose a hot water system

Here are some things to consider when looking to upgrade your hot water system.

The size of your home and family

Storage and solar hot water systems are sized according to how many people will be using them, compared to continuous flow hot water systems which are sized according to the number of outlets in the home.

Climate and available energy sources

Electricity, natural gas, LPG or solar? Depending on which water heating energy source is available, you'll need to consider how the cost of these sources might fluctuate throughout the year. 

Installation space

Will the system be installed inside or outside? If you’re moving to a solar hot water system (available at select NSW & QLD stores), will you have appropriate north-facing roof space for solar collectors?


Budget will also influence the system you purchase. Keep in mind that additional charges may occur on the day of installation based on the specific needs and requirements of your hot water system installation.
