Energy Efficiency Saves You Money
While the cost of energy is going up, you can be confident the operating cost of your Hot Spring Spa will keep you down to earth.
- Compared with most spas, Hot Spring Spas cost 1/2 to 1/3 less to operate.
- Our 110V models 355 gallons (or less) are documented to cost under $20/month in the coldest winter months including surcharges and winter rates for the largest utilities in the Puget Sound area.
Every Hot Spring Spa has multiple energy saving features built-in to make it the most EnergySmart Spa™ in the industry.
Totally Insulated Construction
Hot Spring Spas use multiple layers of high-density, closed-cell polyurethane foam, like a commercial freezer. Closed-cell foam is water repellent, while less expensive, open-cell foam can absorb water, which reduces its insulating value.
Exclusive Insulated Cover
While many spa manufacturers purchase covers from outside suppliers, Hot Spring makes its own covers for a customized fit. Using an exclusive "shoe" in the cover hinge that forms a tight seal, each cover locks in heat with 1.5 or 2 lb. foam insulation. The covers are made of durable marine-grade vinyl and are tapered for water run-off. They feature child-resistant safety locks and are UL classified in accordance with ASTM safety standards.
Constant Heat
Driving innovation, Hot Spring Spas' energy saving features maintain the water at your desired temperature, eliminating expensive heating, cooling and filtration cycles.
Superior Filtration
Hot Spring Spa’s superior filtration system and optional EverFresh® water care system feature the highly effective FreshWater® III CD ozone generator, reducing the need to refill the spa and heat new water.
Efficient Jet Pump
Unlike oversized, high-horsepower jet pumps used in many other brands, the single-speed Wavemaster® jet pump uses only the energy needed to deliver a powerful hydromassage experience.
Dedicated Circulation Pump
The single-speed Silent Flo 5000® circulation pump ensures 24-hour filtration while using less energy to operate than a 40-watt light bulb.
Warm Air Induction System
A patented pump shroud captures heated air (110° - 130°) generated by the jet pump and directs it into the spa's water, slowing the water's cool-down rate and saving energy.
No-Fault® Heater
The unique, patented design ensures maximum efficiency by transferring over 98% of the heat it produces into the water...minimizing waste and energy cost.
LED Interior Light
Uses far less energy than a standard light bulb. In fact, many cities are converting their traffic signals to low-watt LED lights to conserve energy.
SmartJet® System
This system provides a variety of massage options without oversized or multiple jet pumps. Simply turn on the jet system you want...and nothing more.
Hydraulically Efficient Plumbing
A manifold plumbing system minimizes restrictions in the water flow, so less jet horsepower (and less energy) is required to deliver a strong feel at the jets.
Award-Winning Energy Efficiency
An industry leader in the design, engineering, and manufacturing of energy-efficient hot tubs, Hot Spring is the winner of a 2008 ENVY Award for energy-efficient hot tub design and the 2008 Flex Your Power Award from the State of California for leadership in energy-efficient manufacturing operations.
So relax. Energy efficiency is just one more quality component of a Hot Spring Spa. In the long run, quality always costs less. Can you really afford anything less?
