Hot Spring & Caldera Spas are built with energy-efficiency in mind so that you get maximum performance without a high electric bill!

From features like continually operating circulation pumps that draw less energy than a 40-watt light bulb to Insulating Hot Tub Covers with a high R-value and a dense foam core that forms a tight seal to keep the warm water in & the cold air out!

Our hot tubs are fully-foamed with polyurethane foam completely filling the space between the shell, the ground and the cabinet, making them the best insulated spas you can own.

The pumps and heater maximize performance while minimizing energy use by transferring much of the energy used by the pump into the water as "heat!"

   We Set the Standard

All of our hot tub models have been certified to the California Energy Commission (CEC) in accordance with California law. California sets the standard for energy-efficiency , so you can have peace of mind knowing that your spa is designed to keep operating costs low no matter where you live!
