Swim spas can solve many problems faced by potential owners of full-sized swimming pools, smaller lap pools, and hot tubs. A swim spa gives the user the benefit of all these different types of water tanks while still being versatile and practical. The water temperature can be increased to a point where it acts like a hot tub or brought down to a level where it’s comfortable for a swimming workout. This may make you wonder how are swim spas heated, so we’ve come up with an article that covers the elements of operating a swim spa and how to heat the water efficiently.
The Ideal Water Temperature
The ideal water temperature of your swim spa really depends on how you’re going to be using it. For a swimming workout, the water should be around 27 to 30 degrees Celsius. This is a comfortable temperature range that will prevent you from overheating during an intense session. For those who are looking for a hot tub experience, you can raise the water temperature to as high as 40 degrees Celsius. It does take some time to raise the water temperature, so keep this in mind if you’re planning a hot tub party. To speed up the heating process it helps to put the cover on the swim spa.
Water Temperature Maintenance
Maintaining a consistent water temperature is much more energy-efficient than allowing it to return to ambient temperatures after each use. Therefore, you should keep the water heater running even when your swim spa is not in use. The exception to this is if you don’t plan on using your swim spa for several weeks. If you won’t be using your swim spa for short periods of time, it’s more efficient to simply turn down the temperature by a few degrees rather than turning off the heater altogether.
Insulation and Covers
The amount of insulation that your swim spa has will determine how energy efficient it is. Inground swim spas can benefit from the natural insulating properties of the ground. If you have an above-ground model and you plan on using your swim spa during the colder months, it’ll be cheaper to invest in extra insulation upfront rather than pay for the electricity needed to keep the water warm. A well-fitting, highly insulated swim spa cover will also go a long way in reducing the amount of heat loss the water experiences when the swim spa isn’t in use.
One of the benefits of a swim spa compared to a lap pool or full-sized swimming pool is that you can run it during the winter. Due to the reduced water volume, you’ll still be able to practice your stroke or relax in a hot tub style environment even if the outdoor temperatures drop below zero. If you don’t plan to use your swim spa over the winter, you’ll need to empty the tub completely. Failure to do so could allow the water to freeze which can cause damage to the tank, plumbing, and other components.
If you’re concerned about energy efficiency, it pays to shop around when deciding on a swim spa. Certain models are designed to be more energy-efficient than others. Some have more insulation whereas others are manufactured for those in warmer climates. If you think you’d like to use your swim spa for swimming and hot tub soaking, you might want to look into models which have separate tanks to allow both activities to take place at the same time. This would also reduce the need to be constantly adjusting the water temperature.
