Does a Swim Spa Use More Energy than a Hot Tub?

In short, yes a swim spa does use more energy than a hot tub mainly because it is larger. But there are some factors that will impact how much energy is used. These include how much you use your swim spa, where you live, how cold your winters are, the temperature, jets, and so on. 

In the summer, however, the energy usage of a swim spa is likely comparable to that of a hot tub.
