Hot Tub Energy Efficiency Tips

Invest in a Quality Cover

Your hot tub cover is its first line of defense against energy loss. Up to 60% of heat escapes through the surface when the cover is old, damaged, or poorly fitted. It’s a big number! Look for these signs that it’s time to replace your cover:

• Water-logging (cover becomes too heavy to lift)
• Visible cracks or tears
• Compressed or misshapen foam interior
• Gaps between the cover and tub

A thing to keep in mind—a quality cover typically pays for itself within a year through energy savings alone. It really is one the greatest investments you can make to save hundreds on your hot tub each year.

Optimize Your Temperature Settings

Each degree you lower your hot tub’s temperature translates to energy savings. Consider the following strategies:

• Reduce temperature by 2-3 degrees during periods of infrequent use
• Lower temperature significantly (to around 95°F) during vacations
• Use a floating thermal blanket under the main cover for additional insulation

Bonus pro tip: Find your sweet spot between comfort and efficiency. Most users find 100-102°F perfectly comfortable, rather than the standard 104°F.

Master Your Filtration Cycles

Your hot tub filtration system is designed to keep your water clean and clear, but it doesn’t have to run nonstop to be effective. By programming your filtration cycles efficiently, you can maintain water quality while also saving energy. Here’s how to optimize your system:

Take advantage of off-peak electricity hours: Schedule your filtration cycles during times when electricity rates are lower. This can help reduce your energy costs without compromising the cleanliness of your water.

Adjust filtration time based on the season:

• In warmer months: Run your filtration system for a total of 4-6 hours per day. Warmer temperatures can promote the growth of bacteria and algae, so maintaining regular filtration is crucial, but you don’t need to overdo it.
• In colder months: Increase the total run time to 6-8 hours per day. Cold weather can slow the natural breakdown of contaminants, so extended filtration is beneficial.

Use shorter, more frequent cycles: Instead of running the system for one long, continuous period, split the filtration time into multiple shorter cycles. This approach is more efficient and helps maintain consistent water circulation, which improves filtration performance and keeps the water cleaner.

By programming your hot tub filtration system wisely, you can enjoy clear and safe water while minimizing energy usage and costs.

Maintain All Things Hot Tub

Regular maintenance isn’t just about longevity—it’s also about efficiency. Consider the following for your check list:

• Clean or replace filters monthly
• Check and repair any leaks promptly
• Keep jets and pumps free from debris
• Service your heater annually

But why go through all of this? A well-maintained hot tub uses up to 25% less energy than a neglected one.

Strategic Placement and Protection

Yes, you can put your hot tub just about anywhere, but there are some things to keep in mind for placement as well as some moves to make to keep the elements from tapping into your energy bill. 

• Install wind barriers (privacy screens or landscaping)
• Place the tub in a sheltered area if possible
• Consider adding extra insulation to the cabinet
• Use a thermal pad under the tub to prevent heat loss through the base

Monitor and Track

Keep an eye on your energy bills and usage patterns:

• Record monthly energy costs
• Note temperature settings and usage frequency
• Track maintenance activities
• Adjust habits based on what you learn

The Bottom Line

Implementing these energy-saving strategies can reduce your hot tub’s operating costs by 25-45% annually. For a typical hot tub user, this translates to savings of $200-500 per year! Plus, these practices often extend your tub’s lifespan and reduce the need for repairs.

Remember, the key to maximum savings is consistency. Start implementing these tips today, and you’ll see the difference in your next energy bill. Your wallet—and the environment—will thank you.
