Pool Heating

When you've invested in a swimming pool, you should be able to enjoy it beyond summer, or even all year long.

The ideal swimming pool temperature is 25 to 26°C but without additional heating, it usually stays between 18 and 20°C. Even when your swimming pool absorbs heat during the day, the temperature drops at night, making it difficult to keep your pool warm naturally.

At AstralPool, we offer a range of affordable heating options to help you get more use out of your swimming pool.


Gas Heaters Vs Heat pumps

Gas Heaters are generally available in larger sizes with much faster heating times than heat pumps.  What does this mean?   You can turn on your gas heater on Friday or even Saturday morning and be swimming Saturday afternoon.   Gas Pool heaters are generally available with heating outputs of 14kW to 100 kW.

Heat Pumps are typically restricted in their heating capacity because there is a limit to how much electricity is available to your home.  Typically, residential heat pumps will range between 7kW and 25 kW.  To put it in perspective, your electric kettle is probably 2 kW so a 7 kW will not heat a whole swimming pool up very much.

 

Gas heating

A gas heater is a cost-effective way to heat your swimming pool to a comfortable swimming temperature all year round. It can provide on-demand heating, which means your pool will be at the perfect temperature when you want it, regardless of the weather conditions.

When you're choosing a gas heater for your pool, you should consider these factors:

  • Swimming pool size
  • Maximum temperature
  • Heating time
  • Your swimming season

Heat pumps

A heat pump is a very energy-efficient heating option for your pool and a great alternative for areas that don't have a natural gas connection. It uses the same technology as reverse-cycle air conditioners, extracting heat from the air and transferring it to water through a series of processes.

When choosing a heat pump, you should consider the following factors:

  • Geographic location and climate*
  • Maximum temperature
  • Swimming pool size
  • Indoor/outdoor location
  • Your swimming season

*Heat pumps are ideal for warmer, tropical climates.

Solar heating

A solar heating system of the right size can keep your pool at a comfortable swimming temperature and extend your swimming season.

Solar pool heaters use energy and heat from the sun, so they're best suited to sunny areas. They're one of the most economical and environmentally-friendly heating options and, when combined with a gas booster, provide the most efficient temperature control, regardless of the sun.

Here's what you should consider when choosing a solar heating system:

  • Swimming pool size
  • Roof orientation and shade
  • Pool and roof colour
  • Amount of shade and wind
  • Your desired swimming season

Energy Prices

Energy prices have changed dramatically over the last 10 years.   In general, a heat pump is cheaper to operate because they use the ambient air temperature to create the heat for your pool.   For every 1 kW of electricity used, a heat pump will generate between 3.5kW to 5 kW of heating for your pool (depending on air temperature, humidity and water temperature).

A gas heater however, operates at between 80 and 95% efficiency. This means for every 1 unit of gas used, between 80% and 95% is converted into heat energy for your pool.

HOWEVER, the heat pump will generally be left operating every day, all summer long.  Remember the heat pump is limited in size, so it will take days to heat the pool, and once heated, it is left on to maintain the heat.

The Gas Heater however, will take between 4 hours and 24 hours to heat the pool (depending on the size and model chosen). Therefore, the pool can be heated for the weekend or just over the school holidays and then turned off.   The heat pump meanwhile will still be operating everyday just in case you want to swim.

Remember, the gas heater can be turned on Saturday morning and everyone will be enjoying a beautiful warm pool Saturday arvo.

 

As a rule of thumb...

Natural Gas is readily available in Sydney, Melbourne, Adelaide and Perth and their surrounding areas and it very often makes sense to install a gas heater.   In these areas, the flexibility to heat “on demand” makes gas heating convenient and very economical.

North of Sydney, Brisbane and most of Queensland and Northern Territory has a warmer climate and the heating requirements of a pool are less.  Heat Pumps are often ideal for these areas.

If you only want to take the chill off the water and have the kids enjoy the pool during school holidays a small heat pump is often a very economical and convenient heating system.  A BPA 400 or BPA 600 will only require readily available power supply and so are economical to install and will heat your pool (depending on pool size) the 5 or 6 degrees necessary to turn the pool into a warm oasis.
