How to heat a swimming pool with solar panels?

Solar Pool heating Melbourne will significantly reduce the cost of heating your swimming pool. Whilst having a low annual operating cost, solar pool heating is one of the most effective ways to keep your pool warm all year round.  

How does it work? 

The solar pool heating system is made up of the following: 

  • Solar Collector – A device used to circulate pool water to be warmed by the sun  
  • Filter – Removal of leaves and debris before water enters the collector 
  • Pump –the pump circulates water from the filter to the collector and back into the pool heated 
  • Flow Control Valve – A device used to divert pool water through to the solar collector  

Pool water is collected and pumped through the filter and then into solar collectors where it is heated. It is then pumped back into the pool. In hot climates where you require your pool to be cooled, the water can also be circulated at night.  

Heat Pumps  

If you think a heat pump may be better suited to you, you can still use solar panels. Many customers that already have solar panels on their roof may use heat pumps to warm their pools. Your heat pump can be run on a timer which ensures it only runs during the day whilst your solar panels are producing free energy.  

Pros and cons  

There are a number of pros and cons to consider when deciding whether solar pool heating is the option for your pool. These include: 

The Pros: 


Depending on your energy usage, solar panels can be a relatively inexpensive. With growing popularity, solar panels have become more affordable than ever before! 

Easy to Install  

Compared to other pool heating solutions, solar pool heating is relatively easy to install. Whilst, other heating solutions require plumbing, solar pool heating doesn’t. Significantly reducing the cost of installing your new heating solution.  


Your new solar pool heater is going to last you for at least 10 – 20 years with minimal issues as long as they are maintained. Despite being made out of durable materials; your solar heating must be maintained to ensure longevity of the system.  

The Cons: 


Your solar pool heating system will be significantly more visible than many of the other heating solutions on the market. However, we find that not many people mind the look of the solar panels!  


Your solar panels will require a sizable area to be installed. This means you need to dedicate a large area of your roof or yard to the solar panels. 

Your Output will vary  

Unlike other traditional heating solutions, energy from your solar panels can be unpredictable! Your solar panels rely on the sun, so if it is a cloudy or rainy day your output will be lower. Fortunately, you aren’t likely to be swimming on cold and rainy days anyway!
