Common Mistakes That Increase Hot Tub Energy Consumption

Hot tubs are a luxurious addition to any home, providing relaxation and therapeutic benefits. However, without proper maintenance and energy-saving strategies, your hot tub can become a significant drain on your electricity bill. To help you save money while enjoying your spa, here are the common mistakes that increase hot tub energy consumption—and how you can avoid them.

1. Neglecting the Hot Tub Cover

A damaged or poorly fitted hot tub cover can lead to significant heat loss, forcing the heater to work overtime. This is one of the most common reasons for high energy consumption.

How to Fix It:

• Ensure your cover fits snugly and seals tightly.
• Replace old or waterlogged covers with energy-efficient, insulated ones.
• Use a thermal blanket under the cover for additional insulation.

2. Setting the Temperature Too High

Keeping your hot tub at a consistently high temperature can drastically increase energy usage. Many owners set the thermostat higher than necessary, especially when the spa isn’t in use.

How to Fix It:

• Lower the temperature by a few degrees when the hot tub isn’t in use.
• Use programmable timers or energy-saving modes if your hot tub has these features.

3. Running the Jets Continuously

Hot tub jets enhance the spa experience but require energy to operate. Running them for long periods can lead to unnecessary energy consumption.

How to Fix It:

• Use the jets sparingly, especially if you’re not in the tub.
• Turn off the jets after each use.

4. Poor Maintenance of Filters

Dirty or clogged filters force the hot tub’s pump to work harder, which increases energy consumption. This also reduces the overall efficiency of your spa.

How to Fix It:

• Clean filters every 2-4 weeks, depending on usage.
• Replace filters every 12-18 months, or as recommended by the manufacturer.

5. Ignoring Water Chemistry

Unbalanced water chemistry can lead to buildup and scaling, which affects the efficiency of the heater and pump. This, in turn, increases energy consumption.

How to Fix It:

• Regularly test and balance the pH, alkalinity, and sanitizer levels in your hot tub.
• Use water treatments designed to prevent scaling and buildup.

6. Not Utilizing Energy-Efficient Equipment

Older hot tubs or those with outdated equipment are often less energy-efficient. Pumps, heaters, and control systems that are past their prime may consume more power than necessary.

How to Fix It:

• Upgrade to energy-efficient pumps and heaters.
• Look for hot tubs with ENERGY STAR certifications or similar energy-saving features.

7. Overfilling the Hot Tub

An overfilled hot tub can strain the pump and require more energy to heat the excess water.

How to Fix It:

• Only fill the tub to the recommended level.
• Regularly check the water level to ensure it stays consistent.

8. Lack of Routine Maintenance

Failing to perform routine maintenance on your hot tub can lead to inefficiencies, increasing energy use over time.

How to Fix It:

• Schedule regular maintenance checks to ensure all components are in good working order.
• Address issues like leaks or damaged seals promptly.

Enjoy Relaxation While Saving Energy

By addressing these common mistakes, you can ensure your hot tub remains a relaxing and energy-efficient haven. Small changes in maintenance and usage can lead to significant savings while extending the lifespan of your spa.
