What Goes Into An Energy-Efficient Swim Spa?

How Do Swim Spas Use Energy?

To understand energy efficiency in swimming spas, you must first know how the energy is used. Your spa will use energy when heating the water as well as continuously circulating the water, and a small amount of energy for the lights.

Most of the time your hot tub remains covered and unused, but while in use this is when the majority of electric energy will be consumed.



A well-made model that will help keep your energy costs low will have proper insulation. Not all spas are made equal, and if they are not insulated at an optimum level a significant amount of heat loss can occur.

Perimeter insulation made with high-density polyurethane foam will not only prevent heat loss but will also contribute to the physical stability of your spa. High-quality insulation done in this manner will also allow for easy access and maintenance saving you even more on additional costs.

A spa’s attic – or rather its cover – will prevent heat from escaping through the top. This is a significant part of the insulation. Just as you wouldn’t own a house that did not have a properly insulated roof, you wouldn’t want to own a tub that did not have a superior cover. A well-made cover should be 3″-5″ thick and made of high-quality materials.



In order to improve energy efficiency you will want to ensure that you have high-efficiency pumps. You will want to find a reputable company that allows you to still enjoy those relaxing massages from your spa jets while drawing minimal amperage.

Pumps that produce a high amount of water flow do a much better job of pulling contaminants from your water into the filter media. Swim spas that contain high-efficiency pumps will not only provide the finest massage as well as proper filtration, but they won’t break the bank!


Built to Last

Choosing a swimming spa that is durable and made with superior products is especially critical if you live in a harsh climate. Finding a spa that is specifically engineered for these conditions means that it will last longer, cost less to operate, and will be easier to maintain.

The shell of your spa should be durable, so you know it will last a lifetime. A well-built swim spa that is well-maintained can last as long as 20+ years. On the other hand, a spa built with poor-quality products will have to be replaced and disposed of, causing negative impacts on our planet’s sustainability.

Throughout this article, we have uncovered how a backyard spa uses energy, and how proper insulation and high-efficiency pumps can help you remain energy conscious. A well-made model with durable and superior products can last you a lifetime and help you keep those energy bills down!
