Top 5 Hot Tub Energy Saving Tips

Hot tubs are a perfect way to relax, but they can come with high energy costs if not properly maintained. Fortunately, there are several strategies to help you save energy and lower your monthly bills without compromising your enjoyment. Below, we share our top 5 hot tub energy saving tips to keep your spa experience stress-free and budget friendly.

1. Use a hot tub thermal blanket

A hot tub thermal blanket is one of the simplest and most effective tools for saving energy. This lightweight, floating cover adds an extra layer of insulation by sitting directly on the water’s surface, reducing heat loss and evaporation. When used alongside a standard hot tub cover, a thermal blanket can significantly lower the workload on your heater, translating to noticeable energy savings. Additionally, it helps maintain water levels, so you’ll spend less time refilling and reheating your hot tub.

2. Invest in a high-quality hot tub cover

A well-insulated hot tub cover is essential for minimising heat loss and it’s at the top of our hot tub energy saving tips. Over time, hot tub covers can degrade, losing their ability to retain heat effectively. Regularly check for cracks, tears, or waterlogging—issues that can compromise the cover’s efficiency. Look for a cover with a thick foam core and ensure a snug fit for maximum insulation. Pairing your hot tub cover with a thermal blanket creates a double barrier against heat loss, giving you even greater energy savings.

3. Install a heat pump

Switching to a heat pump is a game-changer for energy efficiency. Unlike traditional electric heaters, heat pumps use ambient air to heat the water, consuming significantly less electricity. While the upfront cost may be higher, the long-term savings make it a worthwhile investment. Heat pumps are especially effective in mild climates where they can draw heat from the surrounding air year-round, so they’re perfect for the UK. Modern heat pumps are also designed to operate quietly, ensuring your spa experience remains peaceful.

4. Optimise your hot tub temperature

Keeping your hot tub at a consistent temperature, rather than letting it cool down completely between uses, can save energy in the long run. Lowering the temperature slightly when the hot tub is not in use can further reduce energy consumption without requiring a full reheat every time you want to soak. Many hot tubs also come with programmable timers, allowing you to set temperature schedules that align with your usage patterns. There are also apps which allow you to control your hot tub remotely, so it can be ready for when you want to use it.

5. Maintain your hot tub regularly

Proper maintenance plays a key role in energy efficiency. Dirty filters force the pump and heater to work harder, consuming more energy. Clean or replace filters as recommended by the manufacturer to keep your system running smoothly. Additionally, inspect your hot tub for leaks or damaged components that could lead to heat and energy loss. Regular water balancing also ensures optimal performance and reduces strain on the heating system.

By following these hot tub energy saving tips, you can enjoy your spa while minimising its impact on your energy bills. Whether you invest in a hot tub thermal blanket, upgrade to a heat pump, or simply stay on top of regular maintenance, small changes can lead to significant savings. Start implementing these strategies today and relax knowing you’ve made your hot tub more energy efficient.
