Where the money goes
Estimated breakdown for your configuration
An undersized heater never quite gets the pool warm and runs constantly. Size it to the pool and your climate, and always pair it with a blanket to keep the heat in.
Ways to save
- A pool blanket lets you run a smaller, cheaper heater and slashes running cost.
- Heat pumps cost more upfront than gas but far less to run for regular use.
How we estimate this
Most Australian pools need a 9kW to 18kW heater in 2026, costing roughly $3,000 to $12,000 supplied and installed depending on pool size and heater type. Bigger pools and year-round use need more output.

What a pool heater size costs in Adelaide
Sizing an Adelaide pool heater starts from the pool's surface area and volume, the temperature rise wanted above the ambient, and whether a cover is fitted, because most heat is lost from the surface, so a larger pool and a bigger rise need a bigger heater, and a cover cuts the loss. The heater type is the big choice: gas heats fast, a heat pump is cheaper to run regularly, and solar is cheapest but weather-dependent. The affordable labour that marks the city out keeps the install the cheapest of any mainland capital.
Adelaide's dry Mediterranean summers are hot and sunny, so solar heating is efficient and extends the shoulder seasons, while the cooler winters need a bigger rise for a winter swim. A cover holds heat against the cool nights and cuts evaporation in the dry climate. A stone cottage with a newer pool is a common install. The cheap local labour makes the install more affordable than in the dearer capitals. A gas heater is connected by a licensed gas fitter, a heat pump by a licensed electrician with a refrigeration technician, and solar by an accredited installer, in South Australia.
A pool heater is sized by the pool and the climate, and installed by the relevant licensed trade — a licensed gas fitter for a gas heater, a licensed electrician and refrigeration technician for a heat pump, or an accredited installer for solar, in South Australia under Consumer and Business Services. For an Adelaide pool, the clearest way to size a heater is by the surface area and volume, the temperature rise wanted, and whether a cover is used, with cheap labour keeping the install affordable.
