7 Energy Saving Tips for Your Hot Tub

Here are some tips on how to save energy and energy costs:


1. Your Spa Cover


In our homes, up to 80% of heat loss is through the roof. Since heat rises the insulation in your roof is important in keeping utility costs down.  The same principle applies to your hot tub.  Even though most hot tubs today have insulated shells, most of the heat loss will still be through the spa cover.

If your cover is in good condition, make sure the tie straps are snug and latched when the spa is not in use.  This will reduce heat leakage. If your cover has deteriorated, heat leaks will occur at the hinge-fold. The spa shell rim is also prone to heat leaks due to improper seating of the cover edges. A good cover will provide a “vacuum heat seal” keeping more heat in your hot tub. Read our blog about replacing your cover here.

If your old cover is heavy, the foam-core insulation has become water-logged. A waterlogged cover will have almost no R-value, wasting your heating dollars. A  high-quality replacement cover will save energy, last longer, and be more resistant to water absorption.
2. Creating Windbreaks

3. Vacation Mode

Turn down the thermostat when you are on vacation. If you will be gone for a week or more during warmer months, you can set it at its lowest level or turn off the heater. In freezing weather, some heating must continue to prevent damage to the pipes. If you are gone a lot during the winter months you can winterize your hot tub. The entails removing the water from the plumbing system.

4. Air Jets, Lights and Blowers

Turn hot tub jets off, when not in use. Air induction jets are wonderful features which provide you with a soothing massage.  But as they induce air into the spa water, they also lower the water temperature.  You will have to replace that heat loss by using the spa heater.

The energy impact will be minimal during use, but remember to shut-off air and water lights when the spa is not in use.
Powered Air Blowers used to be popular, but are being phased out. Not only are they loud (sounding like a vacuum cleaner!) they consume a lot of energy. They actually lower the water temperature by injecting cool air into the water, wasting even more energy to heat it back up.

5. Filter Cartridges and Plumbing System

Clogged or worn-out spa filters reduce the circulation of your spa water. This causes pump motor strain, and your heater element to perform poorly. It’s recommended to rinse off your filter at least every 2 weeks. When you change your water, you should soak your filter with non-foaming filter cleaning compound.  Replace annually to maintain your spa’s peak performance.  The result is both energy savings and cleaner water.

When you change your spa water, it’s also a good idea to flush the heat and plumbing system with a cleaner such as, Spa System Flush from SeaKlear. This helps maintain water flow and removes calcium build up from your heater element.

6. Conserve Water

Avoid wasting water, in which you would have to replace and reheat. Repair any leaks and adjust jets so that you’re not sending streams of hot water on to your deck.

7. Shopping for a New Spa

Sometimes the best approach is to replace an obsolete, energy wasting spa with a new one which can save 50% or more in heating costs.  There are several things to look for in a new spa with regard to efficiency. Don’t overbuy horsepower. Some manufacturers play the jet and horsepower numbers game. They offer more and more jets, which need higher horsepower (or many pumps) to feed the jets.
The design and engineering of a spa is much more important than the number of jets. A well engineered spa does not need a lot of jets to provide a great hydro-massage. Remember, very large pump motors consume large amounts of power to run, and can result in huge power bills.
