Pool heating keeps your pool at a comfortable swimming temperature beyond the hottest months. We supply and install solar, electric heat-pump and gas pool heating across Adelaide, typically $3,500 – $9,000 for solar, $5,500 – $12,000 for a heat pump and $6,500 – $15,000+ for gas.

Pool heating cost in Adelaide
Adelaide pool heating typically comes back in three price tiers. The right option for you depends on your pool’s size and exposure, your roof, your power or gas supply and how much of the year you want to swim. Your written quote breaks the cost down line by line.
Solar (rooftop) — $3,500 – $9,000
Roof-mounted solar collectors, a controller and valves. The lowest running cost because the heat comes from the sun, but it needs a suitable, sunny roof and gives less heat on cloudy days and in winter.
Typical scope: collectors, plumbing, controller, install.
Electric heat pump — $5,500 – $12,000
An air-source heat pump sized to your pool. It runs on electricity but moves heat from the air efficiently, so it’s a reliable choice for spring and autumn swimming. Pairs well with rooftop solar panels.
Typical scope: heat pump unit, install, plumbing, controller.
Gas / hybrid — $6,500 – $15,000+
A gas heater (natural gas or LPG), on its own or paired with solar or a heat pump. The fastest heat-up, useful for occasional use or a quick boost, but usually the most expensive to run.
Typical scope: gas heater, install, plumbing, controller.
Solar vs heat pump vs gas
| Solar | Heat pump | Gas | |
|---|---|---|---|
| Install cost | Lowest to mid | Mid | Mid to high |
| Running cost | Lowest | Moderate | Highest |
| Heat-up speed | Slow, weather dependent | Steady | Fast |
| Needs | A suitable sunny roof | Space and a power supply | Gas supply or LPG bottles |
| Best for | A longer warm-weather season | Consistent spring and autumn swimming | Boosting on demand |
Hybrid set-ups, such as solar with a heat pump or gas boost, work well for keen swimmers. Our solar vs heat pump comparison goes into more detail.
Sizing the system to your pool
The right size depends on the pool’s volume and surface area, how exposed it is to wind and shade, the temperature you want and the months you want to swim. An undersized system struggles in the shoulder seasons; an oversized one costs more than it needs to. Your written quote is sized for your actual pool, not a generic recommendation.
Why a pool cover matters
A pool loses much of its heat through evaporation from the surface, especially overnight. A thermal cover keeps far more of that heat in, which makes any heating system work better and cost less to run. We quote heating with a cover, because running heating without one wastes energy.

Frequently asked questions
What is the cheapest way to heat a pool in Adelaide?
Solar heating usually has the lowest running cost because the heat comes from the sun, provided you have a suitable roof. A heat pump costs more to run but gives more consistent heat in spring and autumn. Gas is usually the most expensive to run.
Can I add heating to an existing pool?
Yes. Solar, heat pump and gas systems can all be added to an existing pool. We check your pump, plumbing, roof, power or gas supply and equipment space before quoting.
Do I need a pool cover with heating?
We strongly recommend one. Without a cover, much of the heat is lost overnight. A thermal cover is one of the most effective ways to cut heating running costs.
How much warmer will heating make my pool?
It depends on the system size, your pool, the weather and whether you use a cover. Your quote will set out what the recommended system is sized to achieve for your pool.
