Pool Heating Options Explained
30th October 2024
Want to extend your swimming season and make the most of your pool There are various options for heating your pool – each offering different levels of energy-efficiency.
When you take a dip in your pool, feeling refreshed is the goal, not shivering from cold water. Ideally, you’d want the water to be a comfortable 25°C, which is perfect for relaxation and enjoyment. However, reaching this ideal temperature is easier said than done in most parts of Australia, where pools typically hover between 18 and 20°C without heating – unless you’re lucky enough to live in a warmer climate like Far North Queensland.
To fully enjoy your pool year-round, finding the right heating solution is essential. Fortunately, there are numerous options available, each suited to different environments, pool sizes and energy requirements. Consulting with a pool specialist can help you determine the best solution for your pool, ensuring optimal swimming temperatures and enjoyment, year-round.
Now let’s dive in and explore the different pool heating options available

What’s the best way to heat a swimming pool?
There’s no one-size-fits-all answer to this question. The best pool heating option for your home will depend on various factors, including the size of the pool, your budget and your preferred energy source. Often, your location comes into play, too – the ambient temperature and amount of sunlight your pool gets each day can influence your choice.
If you’re looking for the cheapest way to heat a pool, then the answer will almost always be a solar pool cover or blanket. After the initial purchase, there’s no ongoing energy cost. Just a little effort on your part to pull it out and cover the pool after each swim.
If you’re looking for something a little less hands-on – and more reliable, temperature-wise – then you should consider either a gas pool heater, an electric heat pump or a solar energy system. Each one has its own pros and cons, which we’ll explore below.
Pairing any of the options below with a pool blanket will help to entrap the heat and make your pool heating even more efficient, ensuring your pool stays warm and enjoyable throughout the year.
Solar pool heating
Solar pool heating stands out as a popular choice among pool owners in Australia. Here are some of its key benefits:
- Low annual operating costs: Solar heating systems have minimal ongoing expenses, helping to keep your overall pool maintenance budget in check.
- Environmentally friendly: Harnessing the sun's energy to heat your pool is an eco-conscious choice, reducing environmental impact.
- Effective in most areas of Australia: Solar heating systems are suitable for use across a wide range of Australian climates, providing efficient heating even in regions with moderate sunlight exposure.
- Low maintenance and a long lifespan: Solar heating systems require minimal upkeep and boast a long operational lifespan, offering reliable performance for years to come.
The potential drawbacks include:
- Limited heat generation on rainy days and at night: Solar heating systems rely on sunlight to generate heat, meaning their effectiveness may be reduced during overcast weather conditions or after sunset.
Gas pool heaters
Gas pool heaters offer a viable heating solution, particularly for smaller pools. These heaters use a gas source to warm up water before it is passed back into the pool. The key benefits of gas heating include:
- Quick heating: Gas pool heaters can rapidly raise the water temperature, providing prompt warmth for your pool whenever needed.
- Affordable installation: Gas heating systems are relatively inexpensive to install compared to some other heating options, making them accessible for pool owners on a budget.
- Consistent performance: Regardless of the outside temperature, gas pool heaters maintain their effectiveness, ensuring your pool remains comfortably warm even in cooler weather conditions.
However, there are some drawbacks to consider:
- High operating costs: Gas pool heaters can be costly to run, especially compared to more energy-efficient alternatives such as solar or heat pump systems.
- Limited lifespan: Gas heating systems typically have a shorter lifespan, lasting around five years on average before requiring replacement or significant maintenance.
Electric heat pump
Electric pool heaters work on the same principle as a reverse-cycle air conditioner. Operating in tandem with your pool pump, they extract warm air from the surrounding environment to heat the water in your pool. The key benefits of an electric heat pump include:
- Energy efficiency: Electric heat pumps are highly efficient in their operation, consuming minimal energy while providing effective heating for your pool.
- Low operating costs: Compared to gas heaters, electric heat pumps typically result in lower ongoing operational expenses, contributing to cost savings over time.
- Longer lifespan of about 10 years: Electric heat pumps boast a longer lifespan, lasting approximately 10 years on average before requiring replacement or significant maintenance.
The potential drawbacks of choosing an electric heat pump as your pool heating option include:
- Slow heating: Electric heat pumps may take longer to raise the temperature of your pool compared to gas heaters, requiring a longer wait time before achieving desired warmth.
- Potentially higher initial cost: While electric heat pumps offer long-term savings, they may involve a higher upfront investment than gas heaters.
- Power requirements: Some electric heat pumps may require three-phase power to operate efficiently, which could necessitate additional electrical infrastructure.
The final word
When choosing a pool heating system, it’s a good idea to think beyond the initial purchase price and consider its ongoing running costs and lifespan, too. Talk to a local pool specialist about your options before diving in and choosing your swimming pool heater.
