So you want to install a swimming pool, but you're worried about the impact on the environment. Or maybe you have a swimming pool already and want to reduce your carbon footprint. All that heating, the tonnes of chemicals, and the wasteful water usage. Well, not to worry, as 2025 is the year that you can make your swimming pool more sustainable. And the best part? It may also save you money!
1. **Low voltage LED lights**
There's nothing better than sitting poolside at night, basking in the soft glow of your swimming pool. And who doesn't love a midnight swim in a stunningly-lit pool? Skinny-dip anyone? Time to go the LED route. LED lights are way more efficient than traditional halogen or incandescent lights. They use a fraction of the energy, yet create the same amount of light. Plus, they last 10 times longer. Don't forget to do the same with your landscape lighting too.
2. **Electric heat pumps**
Although gas pool heaters are cheaper initially and they can heat your swimming pool up faster, they actually consume up to three times more energy. Therefore, over time, they end up costing you more in the long run. In fact, the difference is huge. The price for heating your pool using an electric heat pump could halve your costs. So, although your heat pump may cost more to install, once it's in, it could pay for itself in 2 years, making your pool heating more sustainable and affordable.
3. **Variable speed pumps**
OK, a single speed pump has done the job fine for years. It's cheap and you just switch it on and it runs. Yes, but have you noticed how noisy and inefficient it is? It has one speed and one speed only... high! Never mind that you don't need high. High is what you get. So, although a variable speed pump may cost more upfront, it will be far cheaper to run. You can adjust the speed to the exact flow rate you need. It is far quieter too, stays cooler, and lasts longer. But more importantly, when we are trying to reduce our carbon footprint, it uses far less energy.
4. **Salt chlorine generator**
Saltwater pools are better for the environment and your body. If you are lucky enough to have a saltwater swimming pool, a saltwater generator is a must-have. It uses common table salt to produce the necessary chlorine to keep your pool clean and fresh. No chlorine tablets, liquid, or granules. Lower chlorine use means lower chlorine production. So, you're processing fewer chemicals and using less energy.
5. **Automatic pool covers**
If you want to waste less water, a pool cover is essential. The more your pool is covered, the less water evaporates into thin air. But that's not all a pool cover is good for - they are huge energy-savers. Your pool cover keeps the heat in which, let's face it, is pretty key in the chilly old UK! If you keep the cover on, your heater has less work to do. 80% of the heat is lost at night, so it's crucial to cover up as you head off to bed. During the day, the cover creates a greenhouse effect, helping to reduce heat loss. Installing an automatic cover makes it easier and quicker to cover up, so you're less likely to forget.
6. **Pool automation**
Having an automated system for your pool is the only way to go for 2025. It can save you time and money and it's less hassle. Crucially though, it is great for the environment. The brand new SmartPool 400 EcoSmart has some really cool green features which will transform your swimming pool from gas guzzler to something David Attenborough would be happy to swim in. Simple to install and linked to your WiFi, you will be able to control many of your swimming pool functions from the comfort of your phone. Turning on, and importantly, off the lights, controlling the pump and the heating at the touch of a button.

The coolest green feature of the SmartPool 400 EcoSmart is its ability to link the pool systems to the local weather forecast. Its unique eco-timers can be set to heat your pool at the sunniest or hottest part of the day, so you use the least amount of energy possible. You can also use the Solar forecast to run systems during the sunniest part of the day, useful if you have solar panels. It even has a freeze-protect feature that starts your pump to help avoid freezing pipes. This is the swimming pool eco-gadget of 2025 and is the number one step to owning a sustainable pool.
