Hot Tub Energy Use Calculator

Unique features on every HotSpring spa make them energy-efficient so that you can enjoy lower monthly operating costs. The Energy Smart™ Spa HotSpring spas are totally insulated with multiple layers of high density, polyurethane foam, the same material used to insulate commercial freezers. Hot Tub Covers HotSpring Spas pioneered the first rigid, vinyl hot tub cover, creating a higher standard for energy efficiency. The exclusive “shoe” in the cover hinge creates a tight seal that locks in heat. The standard 1.5 lb. and 2.0 lb. foam cores increase the R-factor of the cover, adding to its ability to retain heat.

* Based on a spa set at 39°C used 6 times per week, 15 minutes with the jets on, 15 minutes with the jets off during each use. Testing conducted by an independent third party certified laboratory in a Controlled Environmental Chamber at multiple ambient temperatures using continuous Data Acquisition monitoring of watts, temperature and humidity, with all equipment rigorously calibrated to ensure data accuracy. Testing conducted on representative large, medium and small spa models, with energy values for other models extrapolated from original data. Individual energy consumption will vary depending on water set temperature, actual consumer usage patterns, and actual environmental ambient conditions.
