Is a Swim Spa Heated?

Swim spas offer the best of both worlds – a fantastic way to work out and stay in shape as well as a spa area to relax and unwind. As swim spas are different from hot tubs, often people will ask if a swim spa is heated and what the average temperature is.

Swim spas are in fact heated, making them an excellent choice for the Canadian climate. Unlike a regular backyard swimming pool where usage is limited to only the warmer months in the year (usually under 6 months), a swim spa can be used 365 days a year, maximizing your return on investment.

As swim spas are frequently used for exercise, their temperature is usually kept around 84 degrees, however for those that want a warm spa-like soak, the temperature can be raised to the level of what a hot tub would be – around 100 plus degrees.

One important thing to know about heating a swim spa is that with a quality model, such as Hydropool, it is very cost effective and the temperature can be maintained year-round for usually less than what it costs to buy a cup of coffee each day. Below, we will look at the factors that contribute to a swim spas energy efficiency.


Hydropool industry leading insulation ensures that their swim spas are energy efficient and cost just a few cents a day to run. Designed with cutting-edge Thermal Shield Technology, the swim spa’s hardcover will trap the heat from the water surface when not in use and reuse it. Furthermore, the interior shell is insulated as well as the inner cabinet which contains a Thermal Shield blanket. Both of these features trap and reuse heat produced by the motor.

Thermal Vents

Another energy efficient advantage of a Hydropool swim spa is the thermal vent system. This is designed to regulate the temperature in your swim spa year-round by trapping heat in colder months and allowing heat to escape as needed in the summer.

Energy Efficiency

Not all swim spa models are created equal when it comes to energy efficiency. Hydropool is an industry leader in this field and is recognized for producing some of the most energy efficient swim spa models on the market – which save you substantial money on your monthly utility bills. As an example, a Hydropool swim spa can filter all of the water in the unit in under 40 minutes, while other brands can take up to 8 hours.

Should You Always Keep Your Swim Spa Heated?

The decision whether or not to always keep your swim spa heated largely depends on your usage patterns. If you use your swim spa daily, it is best to keep the spa at your ideal temperature and allow the cover and insulation to maximize energy efficiency. If you only use your swim spa occasionally, you may prefer to turn off the heater in between uses and allow it enough time to heat up before you take a swim. For winter months, however, if you are not planning on using your swim spa, you should drain the water instead of switching off the heat. If the water is left unheated in the swim spa during cold months, you can risk freezing and damaging the spa.
