Is pool heating worth it in Sydney?

Cooling down in the swimming pool on a hot day is the ultimate summer’s pleasure. However, in Sydney, summer can be short-lived and the weather only allows the pool to be used for a few warm months. This renders your swimming pool an expensive luxury feature to maintain unless it’s heated for more than just the summer months.

There are two popular methods of heating residential swimming pools to extend the time your family can enjoy it, particularly in areas of Australia that are cooler. One is through solar panels and the other is through a heat pump.

Below is a comparison of both to evaluate which is a better choice.


Using solar to provide power to heat your pool through a clean and genuine renewable energy source that does not deplete the earth’s natural resources. Solar heating works by direct sunlight heating solar panels installed on your roof that in turn circulates hot water into the swimming pool to warm it up.
Other advantages of solar panels include, they are cost-effective and over a period have a financial return on investment (ROI) reducing gas and electricity bills significantly. Especially given a pool temperature can be programmed to be set to a level of your choice and can be controlled to switch on and off.

Advantages and Disadvantages

  • Solar pool heating is dependant on the weather
  • Environmentally friendly however inconsistent water temperature production can be annoying
  • Solar pool heating can be high maintenance, due to bird attacks
  • Solar pool heaters also may need electric or gas booster in bad weather.

While a solar pool heating system does have some compelling benefits such as being environmentally friendly, cost savings when it’s hot and sunny, however, these are not always compensated by its disadvantages.

Heat Pumps

Heat pumps work in a similar manner to a reverse cycle air conditioning . It draws in the surrounding air and humidity and transforms it into gas. The gas passes through the heat exchanger condenser.

The pool pump circulates the swimming pool water drawn from the pool, it then passes through a filter and to the heat pump water heater. Because the liquid refrigerant gas and water from the pool is pumped through the warmth exchanger at the identical time, the hot gas transfers its heat to the water.

The water is heated to about 3-5 degrees as it passes through and then the warmer water flows back into the pool.

The heat pump method of heating the swimming pool has several advantages and takes the enjoyment of a family swimming pool to a whole new level.

Advantages and Disadvantages

  • Extends the swim season
  • Consistently warm water is more enjoyable to swim in
  • Can be used for therapy
  • Warm water is healthy for stress relief
  • Great for muscles and joints
  • Increases property value
  • Social fun for outdoor entertaining
  • Impressive cost savings and (ROI) when drawing small amounts of power of the grid
  • Even bigger power savings if you have solar power!
  • Cost effective with an attractive ROI due to their longevity
  • If the climate is too cold then the heat pump will have to work harder to heat the water.

We recommend that a heat pump is the most efficient and effective way to warm up a swimming pool with solar panels a close second. The key differentiator between them is the weather. To ensure consistent warm water even in the cooler months, the heat pump is the way to go. It is not reliant on direct sunlight and it can continue to heat the pool even with a few days of bad weather and for that reason, several months of the year. You will get far more use and enjoyment from your pool making the entire investment worthwhile.

Regardless of the heating method you choose, don’t forget a pool cover. Not only will it retain the heat inside the swimming pool, it will slow down the evaporation process and stop debris soiling the pool.
