Hot Tub Energy Efficiency Saves You Money

Your Caldera^® spa is always warm and ready to use, while operating costs are surprisingly affordable. Caldera hot tubs are among the first to meet the stringent Title 20 energy standards established by the California Energy Commission (CEC). Making all Caldera hot tubs even more energy efficient is good for you and for the environment.

The components are engineered to work together, providing the soothing benefits you want from a hot tub while minimizing power consumption.

Many other spas rely on the energy inefficient low speed of a large jet pump for water filtration, heating and/or ozone injection. But the highly efficient EnergyPro^® circulation pump operates continually, drawing less than 40 watts. This saves you money in many ways:

• It enables the EnergyPro hot tub heater to maintain a constant water temperature. For those who use their spa regularly, this is far more cost-efficient than allowing the water to cool down between uses.
• It reduces heater usage, because more than 80% of the energy used by the pump is transferred into the water as “heat.”
• On spas equipped with ozone systems, it allows for continuous injection of ozone into the water. Round-the-clock circulation helps the ozone generator provide ongoing protection for hot tub users.

Heat Retention The key to low operating costs is effective heat retention. With a Caldera spa, polyurethane foam completely fills the space between the shell, the ground and the cabinet, making it among the best insulated spas you can own.

Insulating Cover Each Caldera spa comes with a custom–fit hot tub cover to form an effective insulation barrier, keeping heat in and cold out.
