Choosing a hot water system in the Top End is different from southern cities. Hot, sunny weather changes what works best. Here is a plain-English comparison to help you decide before you call a plumber. For repairs and replacements, see our hot water systems service.
Electric storage
The simplest and usually the cheapest to buy, but it can cost the most to run because it heats water with electricity all day. A good fit for small households or as a backup.
Gas
Heats water quickly and can run continuously (instantaneous) or from a tank. Needs a gas connection or bottled gas and must be installed by a licensed gas fitter. See when you need a gas plumber.
Solar
Darwin gets plenty of sun, which is why solar hot water has long been popular here. It can cut running costs a lot, usually with an electric or gas booster for cloudy periods. The upfront cost is higher. Older roof-mounted tanks are sometimes lifted off by crane when a system is replaced.
Heat pump
Uses electricity to move heat from the air into your water, so it uses much less power than a standard electric system. A strong option for warm climates. Ask us whether it suits your home.
How to choose
- Household size: larger households need larger tanks or continuous flow.
- Roof and space: solar needs a suitable, sunny roof.
- Running costs vs upfront cost: cheap to buy often means costlier to run.
- Rebates: incentives change, so check current availability before you buy.
