It’s more important than ever to save energy, not just to lower your utility bills but also to help the environment. There are many ways to make your hot tub, whether it’s portable, inflatable, or in the ground, use less energy in 2025.
1. Keep the Heat — This Is the Most Important Rule for Saving Energy
The most important thing you can do to save energy in any hot tub is to keep the heat in.
The spa cover should be your main concern because most modern hot tubs already have well-insulated shells.
- Pick a cover core with a lot of density: Dense foam insulation keeps heat inside.
- Make sure it fits perfectly: The cover should fit snugly over the tub, with the straps and latches properly fastened.
- Fix small tears right away: Even small holes or tears let heat escape.
Keep in mind that heat rises. Your first line of defence against losing energy is a high-quality, well-sealed spa cover.
2. Put in an Extra Layer of Insulation
Think about using a floating insulation blanket for more protection.
It sits right on the water’s surface, which keeps moisture from getting into your cover and makes it last longer and lose less heat.
Turn off the heater in your hot tub completely if you will be gone for more than a few days. There’s no need to waste energy keeping a temperature you won’t use.
You should also know that most hot tubs come from the factory set to 104°F (40°C).
If you lower it to 100–102°F, you can save a lot of energy without making it less comfortable.
3. Keep the Wind Away from Your Hot Tub
Wind can quickly take heat away from the surface of your hot tub.
To stop this from happening, make wind barriers like:
- Fences for privacy
- Landscaping elements
- Enclosures for spas or gazebos
These barriers help keep the water at a certain temperature and cut down on the time the heater needs to run.
If your hot tub has a timer or thermostat that you can program, try using it during off-peak hours (usually before 6 a.m. or after 9 p.m.) to save even more money on your electricity bill.
4. Use the Jet and Filter Wisely
In fact, hot tub jets can waste energy. When jets blow air bubbles into the water, it cools down faster, which makes the heater work harder. When you’re not soaking, don’t use the jets too much.
Also, make sure your filters are clean. A filter that is clogged slows down circulation, which makes the pump work harder and use more power.
For the best performance and water clarity:
- Clean the filters every month
- Change them every year
5. Get Models That Use Less Energy
Look for hot tubs that are made to be energy-efficient if you’re going to buy one in 2025.
Now there are modern options like:
- Variable-speed pumps that change the flow on their own to save energy
- Low-jet designs that let less air in and lose less heat
- Solar-powered heating systems that use the sun’s heat to warm your water naturally
Solar models are becoming more popular, especially because they use panels on roofs or the ground to collect sunlight and move the heat through water pipes without using a lot of electricity.
6. Save Water (and Energy, Too)
Another important part of making a hot tub work better is saving water.
Refilling and reheating your tub uses up both water and electricity. To cut down on waste:
- Fix leaks right away, even small ones, because they add up over time.
- Set the jets so that they don’t splash water outside of the tub.
- Only drain when you have to, which is usually every three to four months for tubs that are used often.
You can use drained water again by watering your lawn or garden, or by sending it to a sanitary sewer if it hasn’t had chemicals added to it in the last 48 to 72 hours.
Last Thoughts
In 2025, saving energy in hot tubs isn’t just about saving money; it’s also about being environmentally friendly.
You can enjoy all the relaxation your hot tub offers while keeping your impact on the environment low by using the right insulation, doing regular maintenance, using smart controls, and using modern technology.
You can save money and help the planet by taking small steps like lowering the temperature, keeping your cover in good shape, and cleaning your filters often.
