Many pool owners are looking for smarter, more efficient ways to keep their swimming pool water warm and running costs down. Whether you use a heat pump to extend your swimming season or simply rely on the sun’s warmth, maintaining consistent water temperature can be a challenge, especially during seasonal changes. This is where a solar pool cover can make a big difference. It’s a simple, cost-effective upgrade that not only works together with your heat pump but also offers many benefits that make pool ownership easier, more sustainable and far more affordable.
How Do Solar Pool Covers Work?
Solar pool covers, also known as solar pool blankets, are designed to float on the surface of your pool and help heat your pool using the sun’s energy. Here’s how they work:
- The bubble layer allows the sunlight to pass through and heat the pool water.
- The solar pool cover then holds the heat in the water and insulates the pool during the day.
- As the temperature drops at night, the cover prevents the heat from escaping, keeping your pool warmer for longer.
- At the same time, it acts as a barrier and significantly reduces water loss through evaporation.

In fact, our Neptune solar pool blankets can increase your pool’s temperature by up to 8°C. And that’s where the Neptune difference comes in.
The Neptune Difference
What sets our Neptune solar pool blankets apart is their Ultradome® Technology.
Its unique bubble shape is engineered with added thickness at the points most exposed to heat and chemicals. By adding two-thirds of the material in the lower layer, the blanket offers superior strength and abrasion resistance.

Beyond Heating: Neptune’s Cost-Saving Benefits
Our Neptune solar pool blankets help heat your pool, but their benefits go well beyond heating. Here’s how they help you save even more:
- Minimise Water Loss
Because Neptune solar pool blankets reduce evaporation by up to 97%, you can save as much as 10,000 litres of water per month. - Reduce Chemical Use
Less evaporation means you can maintain chlorine and salt levels for longer and reduce the need for chemical top-ups by up to 50%. - Energy-Efficient Pool Heating
If you use a heat pump to warm your pool, adding a Neptune solar pool blanket helps lock in the warmth and keep your pool at a steady temperature. It reduces how often your heat pump needs to run, saving you energy costs. - Save Time, Clean Less
Pool maintenance will be easier with a pool cover. They help to keep leaves, dust and debris out of your pool. This cuts down the time you spend cleaning your pool.
Why Every Heat Pump Needs a Solar Pool Cover?
- A solar pool cover helps retain the heat your heat pump generates. This means your heat pump doesn’t have to run as often, but keeps your pool warmer for longer at the same time.
- You’ll reach your desired temperature faster, saving you time and energy.
- In many cases, pairing your heat pump with a solar pool cover means you can even opt for a smaller kW system, lowering upfront costs while still achieving great results.
So, Are Solar Pool Covers Worth It?
Absolutely. With a solar pool cover, you can not only swim in cooler weather but also save on maintenance costs and cleaning time. When paired with one of our energy-efficient Neptune heat pumps, it helps create an even more efficient, cost-effective and eco-friendly pool heating solution.
