Energy Calculator

The energy your spa uses depends on a variety of factors. These factors can vary between your spa model, frequency of use, your mean ambient temperature (average temperature), as well as your electricity rate. This can also be offset if you have alternative energy sources such as solar power.

In order to help spa owners estimate their spa costs, we have provided the below energy calculator to estimate the energy consumption of your spa. This calculator will help you to estimate an average monthly cost of your Hot Spring spa.

* 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.
