Choosing the Right Hot Water System: Gas, Electric, Solar or Heat Pump

2026-05-27

Replacing a hot water system is a decision you only make every ten years or so, so it is worth getting right. Each type of system has its own strengths, and the best choice depends on your household size, your budget and the connections already at your home. Here is a straightforward guide to help you weigh up the options.

Gas Hot Water Systems

Gas systems heat water quickly and can be a great fit for families and larger households, particularly where mains gas is already connected. Continuous flow gas units heat water on demand, so you are less likely to run out during back-to-back showers. Where mains gas is not available, LPG bottles are an alternative worth discussing.

Electric Systems

Electric hot water systems are widely used and generally have the lowest upfront cost, which makes them a popular choice. Storage models keep a tank of hot water ready to use, while continuous flow electric units heat water on demand. Running costs can be higher than other options, so it is worth balancing the initial price against ongoing use.

Solar and Heat Pump Options

Solar hot water has a higher upfront cost but can significantly reduce running costs over the long term by harnessing energy from the sun — something our sunny Sunshine Coast climate is well suited to. A booster keeps hot water flowing during cloudy stretches.

Heat pumps are another energy-efficient option, drawing warmth from the surrounding air to heat your water. Both solar and heat pump systems need a little more space, so we will talk you through what fits your home.

How to Choose

Start with your household size and typical hot water use, then consider the connections you already have and how much space is available. A large family on mains gas will have different needs to a small household looking to cut running costs. There is no single right answer — the best system is the one that suits how you actually live.
