Leading Energy Efficiency
The Hot Spring® Energy Smart™ system ensures that your spa will be hot and ready when you are while keeping energy costs low.
Energy Features
High-Density Foam
Insulation
Multiple layers of the same, high-density polyurethane foam used in commercial freezers insulate the spa shell to help lock in heat.
Available on – Highlife Collection spas.
FIBERCOR INSULATION
This exclusive insulation fills the cabinet completely with a density four times greater than the 8 kg/m
Available on – Limelight Collection spas and HotSpot Collection spas.
HotSpring Spa Covers
Custom-fit covers ensure a tight seal to lock in heat. Dense foam cores and an exclusive hinge seal increase insulating ability for additional energy efficiency.
Insulated Base Pan
Structural ribbing on the bottom of Highlife Collection spas increases energy efficiency by creating insulating air space and minimising contact with cold ground.
No-Fault Heater
This patented heater uses a unique housing and heater element that maximises heat transfer.

1: Assumes standby-only use for one week, maintaining a water temperature of 38 °C.
2: Assumes four days of use and three days with standby-only operation for one week, maintaining a water temperature of 38 °C. “Usage” is defined as a 20-minute session in the hot tub—10 minutes with all jets on and 10 minutes without jets.
Testing was performed in October 2022 in a ULcertified chamber per the ANSI/APSP/ICC-14 2019.
Individual energy consumption will vary depending on your specific model, set water temperature, consumer usage patterns, and environmental ambient conditions.
