Owning a hot tub is one of the best ways to relax and unwind—but when temperatures rise, so can your energy bill. The good news? With a few smart adjustments, you can enjoy your spa all summer long without breaking the bank.
Here’s how to improve hot tub energy efficiency during the warmer months, saving money while keeping your backyard retreat running smoothly.
Tips to Improve Hot Tub Energy Efficiency
1. Lower the Temperature
You don’t need a 104°F soak in July. In warmer weather, dropping your hot tub’s set temperature to 95–98°F (or even lower for a cool plunge) can dramatically reduce energy usage.
Lower temps = less heat loss and less work for your heater.
2. Use a High-Quality, Insulated Cover
A tight-fitting, insulated cover prevents heat from escaping and blocks UV rays. In hot climates, look for covers with reflective tops to block sunlight and reduce internal heating when not in use.
Tip: Always secure the cover after each use and inspect for rips or worn-out seals that could leak heat (or let it in).
3. Optimize Your Filtration Schedule
Your hot tub doesn’t need to run filtration cycles as frequently during the summer. Adjust the schedule in your control panel to run during cooler parts of the day (early morning or evening) when energy demand is lower.
This keeps your water clean while reducing energy strain.
4. Shade Your Spa
Just like parking in the shade keeps your car cooler, placing your spa under a pergola, awning, or umbrella can help regulate internal temperatures and minimize heat gain from the sun.
Less heat gain = less energy needed to maintain your preferred temp.
5. Keep Up with Routine Maintenance
Dirty filters, clogged jets, or unbalanced water force your spa to work harder, consuming more power.
For peak hot tub energy efficiency, be sure to:
- Clean filters monthly (or as needed)
- Maintain proper water chemistry
- Check that jets and plumbing lines are clear
A well-maintained spa is not only safer—it’s also more efficient.
6. Consider Energy-Efficient Upgrades
If your spa is more than 5–10 years old, ask your dealer about:
- High-efficiency circulation pumps
- Smart control systems
- Better-insulated cabinet panels or base upgrades
Many newer spas, like those offered by South East Spas, are designed with built-in energy-saving features that automatically adjust to climate changes.
7. Use Eco Mode or Vacation Settings
Planning to be away or not using your spa every day? Switch to Eco or Economy Mode if your system has it. These modes keep water at a lower holding temp and only heat before scheduled use times—saving significant energy.
Smart Soaking = Summer Savings
You don’t have to choose between enjoying your hot tub and saving on your electric bill. With a few tweaks to your routine and setup, you’ll improve hot tub energy efficiency and still soak in comfort—no matter how hot the weather gets.
