What is the perfect water temperature for a pool?
As a pool heating installer in Sydney, one of the common questions we’re asked by our clients is, what is the perfect water temperature to set my pool heating at? For some of us, as long as the water is not freezing cold or swelteringly hot, we’re quite happy to swim in the pool. We don’t give the temperature much of a thought, because as long as we’re comfortable in the water, why does it matter? However, if you do own your own pool and heating system, this is something you’ll need to consider. You’ll want to set your pool heating to a comfortable temperature that everyone can enjoy. So what is that ideal temperature? Let’s find out.
The average water temperature for an Australian pool
When it comes to pool heating in Sydney, the water temperature is considered optimal between 26 and 28 degrees Celsius. This is warm enough to relax and enjoy the water, but not too warm as to waste electricity or heat you up too much. If you’re planning to use your pool for swimming or exercise purposes, you’ll want to keep the temperature closer to 26 degrees. If you’re just planning to relax and chill out in the pool, set the temperature closer to 28 degrees. So now we’ve discovered the best average temperature for a swimming pool, that’s what we should always set the pool heater to right? Well, not necessarily.
Swimming with seniors
If you live with some older individuals over the age of 60, or you’re planning to have older guests to your house, you may want to reconsider the temperature of your water. As we age, our bodies become more sensitive to temperature. What might feel comfortable for you could feel very uncomfortable for someone older. If the water is too cold, it can become extremely unpleasant. This is especially true for those who may be frail or experiencing arthritis and joint pain. In the same way, a pool that is too hot can cause their body temperature to increase dramatically. This could then lead to fainting or cardio-vascular issues. If you are planning to swim with seniors, the perfect water temperature for the pool is around 30 to 31 degrees Celsius. This is a great temperature for relieving any joint pain, making it perfect for relaxing. It’s also not too hot that it causes any discomfort.

Swimming with children
Some may assume that children will require a lower water temperature. This is due to the amount of activity and movement that is involved with their swimming. Seeing as their body temperature would increase, you may think they require a colder temperature. However, the ideal temperature for children swimming in a pool is around 29 degrees Celsius. This is perfect for loosening their muscles and preventing cramps and injuries. Like seniors, children can also be particularly sensitive to water temperature, especially very young kids. If you do have children, consider upping your water from the average temperature just slightly. It could improve their swimming experience and help them to stay fit and healthy.
Heating considerations
- If you do live with seniors (or you just want to swim in warmer water), it can become extremely expensive to constantly heat the water to 30-31 degrees. If the heat is something you require, you could be better off purchasing a spa which will cost far less to heat.
- Once you start increasing your water temperature beyond the average 26-28 degrees, it can also become a breeding ground for bacteria and algae growth. This will require a more consistent pool cleaning routine in order to keep it well maintained.
- Chlorine and other chemicals also become less effective as the water temperature increases. This means that you will require more chlorine and more consistent chemical maintenance to keep it clean.
Saving money with efficiency
If you’re yet to select a pool heater for your pool, you could save a great deal in operating costs by selecting an efficient pool heat pump in Sydney. Our Madimack Summer Eco Inverter Pool Heat Pump series is built with energy efficiency in mind. This makes it perfect for those looking to save money on their heating bills. Another great way to reduce your heating costs is to purchase a pool blanket. This will help to retain the temperature of your water after it’s been heated. Preventing evaporation, a pool blanket will keep your water significantly warmer for longer.
