Hot water systems
Heating your water can account for up to 30% of your household energy use, so it’s important to make the right choice when looking at gas versus electric hot water systems – and you have more options than you think.
Gas hot water heaters are installed outdoors for efficient venting and generally are built to last between 10 - 20 years.
Half of Australian households have electric hot water systems, and they are usually the cheapest to buy. But, unless you add a solar collector to your hot water system or your system is powered by a solar PV (electric) system, they are more expensive to run.
Another alternative, and possibly the most efficient, is a heat pump water heater. Powered by electricity, heat pumps take warmth from the air to heat your water. Although they may require a more significant investment upfront (but you may be eligible for rebates), they use less electricity than a conventional electric hot water system, saving you significantly in the long run.
