2021 statistics show that  66% of the UK are planning staycations, and so more and more people are looking for homegrown fun and adventures, and perhaps you might be thinking of installing your own swimming pool, or maybe you already have a pool but are looking to reduce running costs and your carbon footprint.

Renewable energy is a surprisingly simple way to heat your pool with clean energy and will help to keep the costs down.

Here are some options


Air Source Heat Pumps and Solar Thermal are the recommended methods for heating outdoor pools in the Summer months because an air source heat pump extracts heat from the outside air in the same way that a fridge extracts heat from its inside. It can get heat from the air even when the temperature is as low as -15° C.  

The heat they extract from the air is constantly being renewed naturally, saving you on fuel costs and reducing harmful CO2 emissions.

If you have an air source heat pump already installed in your home as your main heating source it could double up for your pool, and during the summer, when not used for home heating, you could channel ASHP energy straight into warming your pool water.

Note, you can get the renewable heat incentive for an air source heat pump that you’re using to heat your home and doubling it up for your pool, but you cannot get the RHI for just the pool alone.


Heating an indoor pools is slightly different because they’re in use all year round.  Ground source heat pumps are considered to be the most efficient form of pool heating because they’re able to get the pool to a consistent temperature.

Depending on the space you have ground source heat pumps can be laid vertically or horizontally.


Solar panels are extremely efficient and cheap to run, as well as having no additional costs once installed. Solar panels are known to be low maintenance and extremely durable, they can happily last for up to 20 years!
