Energy efficient swim spas: Save money while you swim

Whether you are dedicated to reducing your impact on the environment, are looking to reduce your costs and maintenance associated with your swim spa, or both, energy efficient swim spas offer a variety of benefits.

This article will delve into the topic of energy efficient swim spas, including what they are, the benefits of energy efficient swim spas, how you can save money while you swim, and what factors determine a swim spa’s energy efficiency. You will also learn about some of the energy efficient aspects featured in Sundance® Spas, which takes pride in its swim spa models that are highly energy efficient.

What is an energy efficient swim spa?
An energy efficient swim spa can be known by many names, including an eco-friendly swim spa, a low energy spa, or a green swim spa. All of these refer to the fact that the swim spa uses materials and innovations that are designed to help preserve energy, reduce your carbon footprint, and ultimately keep your utility and maintenance costs down.

The energy efficiency of any given swim spa will vary based on a few key factors, such as the materials used, insulation quality, effectiveness of the swim spa cover, electrical configuration of the swim spa, and smart technology that can help you track and monitor your usage.

Benefits of an energy efficient swim spa
There are many perks of having an energy efficient swim spa. Here are just a few:

Lower monthly energy bills—Thanks to superior materials, great insulation, smart technology, and an excellent swim spa cover, you can actively retain your swim spa water’s heat while also keeping your utility costs down. That is really a win-win while you swim.

Reduce your environmental impact—Preservation of our planet is a global issue, and everyone’s contributions matter, no matter how big or small. Doing your part by consciously choosing a highly energy efficient swim spa is not only good for your bottom line, but it’s also good for a worldwide cause, and that feels good, too.

Lower maintenance costs—The durable build and sustainable materials of a luxury energy efficient swim spa will likely equate to lower maintenance costs in the long run. This is another way you will save money while you swim when you choose an energy efficient swim spa.

Water conservation—If you protect your swim spa with a well-made, tight-fitting cover and maintain it well, you should be able to go up to six months between water changes, with normal usage. Over the course of the lifespan of your swim spa, this can equate to thousands of gallons of water saved, all while keeping your water fresh and ready for swimming and soaking.

What factors impact your swim spa’s energy efficiency?
There are a number of factors that can impact the energy efficiency of your swim spa. These can include:

Sustainable materials—Look for a swim spa shell made with long-lasting acrylic or composite layers that are rated for 15 years or more.

Superior insulation—Proper insulation cannot be underestimated when it comes to sustainability. Seek a swim spa with high-density full-foam insulation that surrounds the shell and cabinet to minimize heat loss.

High-quality swim spa cover—Make sure to preserve your swim spa with a well-fitting cover to lock in your water’s heat and reduce evaporation, which is a major contributor to heat loss.

Size and volume of your swim spa—Naturally, the larger and deeper your swim spa is, the more water will be required to fill it and heat it, which uses more energy. When shopping for a swim spa, keep size in mind. What size do you actually need, and will you actually use it? Could you potentially size down for the sake of conservation?

Usage and temperature setting—The more you use your swim spa and the higher the temperature, the more energy it will require.

Climate—If you live in a cold region of the world or one with extreme temperatures, it will take more energy to adjust and retain the temperature of your swim spa. Some manufacturers, such as Sundance® Spas, may offer an additional layer of protection by way of added factory-installed insulation between the frame and siding to enhance heat retention and energy efficiency.

Electrical configuration—Typically, 240VAC models are more energy efficient for heating than 120VAC models.

Pumps and heaters—Look for variable-speed pumps and energy-efficient heaters, which only use the required energy, unlike traditional single-speed pumps.

Tips for buying and using energy efficient swim spas

• Search swim spa lines that exceed California Energy Commission standards with factors such as full-foam insulation, sustainable materials, efficient motors, and integrated energy-smart controls and technology like the Sundance® Spas SmartTub® system, for example.
• If you are already a swim spa owner looking to upgrade to a more energy efficient model, look into the trade-in programs of your swim spa’s brand or dealer. Some offer you the ability to upgrade to a more efficient model, while your old model can be refurbished or the components of it can be recycled.
• Use your swim spa during off-peak hours of your local electric company. Even slightly adjusting the temperature of your swim spa water by just one or two degrees when not in use can make a difference in your usage and potentially lower your bills.
• Always use your swim spa cover when you’re not swimming or soaking. An excellent swim spa cover will efficiently preserve your water’s heat until you are ready to use it next.
• Buy a high-quality swim spa that is built to last between 15 and 20 years. Replaceable pumps, heaters, and controls have a lesser environmental footprint than a subpar swim spa that may only last five to seven years before it’s no longer usable.
• Ask about your swim spa’s water care. Oftentimes, swim spas that feature lower-chemical water care systems are more eco-friendly. Review your options with your swim spa dealer before making your final purchase.
