The Most Energy Efficient Hot Tubs

Lower Cost to Own and Operate

Everyone says it, but data actually shows that Bullfrog Spa models are the most energy efficient hot tubs in their class.* Bullfrog Spas are the only hot tubs that utilize our patented JetPak Therapy System. This technologically advanced and ultra-efficient water delivery system is designed with up to 90% less plumbing. This system, in conjunction with full foam and more efficient equipment, helps you save energy and ensures that you can relax without worrying about your energy bill.

*Energy calculations based on data compiled by the California Energy Commision and US Energy Information Administration.

Relax, you are saving energy & money…

Bullfrog Spas, the most energy efficient hot tubs in their class.

"I have owned my Bullfrog R7 for a month now, using it 1 hour per day, with a temp of 102 and water cycles 4 hours a day. I was suprised to get my electric bill...only an $18 increase. Good job Bullfrog!"

The JetPak Therapy System Saves Energy

Because Bullfrog Spas are built completely differently, they utilize about 90% less plumbing than conventional hot tubs. Less plumbing equals less friction and less energy used to get water to the jets. In addition, most of the water delivery system in a Bullfrog Spa is inside of the proprietary H2Air Manifold on the JetPak and is submerged in the hot water. Any heat from water in the JetPak manifold transfers directly to the spa water rather than being lost to the cold outside environment. This unique and patented energy-saving feature will keep monthly power bills surprisingly low and will keep you relaxed and worry free!

Engineered to save energy…

Full Foam Insulated Hot Tubs

Bullfrog's full-foam design insulates the spa completely to prevent heat escape. Every single Bullfrog Spa model meets or exceeds the stringent energy guidelines of the California Energy Commission (CEC). With the superior energy efficiency, you will enjoy keeping extra money each month almost as much as you will enjoy relaxing in your spa.

Bullfrog Spas utilize an ultra energy-efficient foam throughout the interior of the spa structure to lock in more heat. Infrared heat mapping shows the difference that full foam insulation makes. A full foam insulated Bullfrog Spa locks in the heat and very little escapes to the outside air. In a poorly insulated conventional hot tub you can see that more heat is lost to the outside environment, requiring the hot tub to use more energy to keep the water warm.

Built to save energy, even in the coldest climates…
