Why HotSpring® Spas Use Less Energy
The EnergySmart® System
The energy efficiency of a hot tub depends largely on its ability to retain heat and minimise the energy required to maintain the desired water temperature. HotSpring® spas combine several technologies within the Energy Smart® system, including high-performance insulation, an insulated cover, efficient heating and continuous water circulation.
Each component is designed to help reduce heat loss and keep your spa warm and ready to enjoy throughout the year.
High-Performance Insulation
Highlife® Collection spas feature full-foam, high-density polyurethane insulation, a material also used in commercial freezers.
Applied in multiple layers of varying densities, the insulation fills the spaces around the spa shell and helps minimise heat loss.
A Cover Designed to Retain Heat
The surface of a spa is an important source of heat loss. HotSpring covers are therefore custom-fitted to each spa model and feature a high-density insulating foam core.
Highlife® Collection covers also feature an insulating hinge seal designed to help minimise heat loss between the two halves of the cover.
No-Fault™ Heater
The No-Fault™ heater is designed to transfer heat efficiently to the spa water. Its titanium housing and heating element also provide excellent resistance to corrosion.
The No-Fault™ heater is backed by a five-year warranty, regardless of water chemistry.
Continuous, Quiet Circulation
The SilentFlo 5000™ circulation pump continuously circulates the spa water 24 hours a day while using less energy than a 40-watt light bulb.
This dedicated circulation pump eliminates the need to use the powerful jet pumps simply to circulate and filter the water, helping reduce both energy consumption and equipment wear.
Recycled Heat
The spa is also designed to capture some of the heat generated within the equipment compartment and transfer it back towards the water, rather than simply allowing that energy to dissipate into the surrounding environment.
Meeting Stringent Energy-Efficiency Standards
HotSpring spas are designed to meet or exceed the energy-efficiency requirements of the California Energy Commission (CEC) and the APSP 14 standard for portable spas.
How Much Energy Does a HotSpring Spa Use?
Actual energy consumption depends on several factors, including the spa model, water temperature, frequency of use, outdoor temperature and installation conditions.
HotSpring has had spa energy consumption measured by an independent certified laboratory under controlled conditions and at different ambient temperatures.
