Swim spa jet propulsion systems and methods
A system and method for circulating water in a swim spa. A recessed chamber formed in the shell of the spa defines a space to hold at least a portion of a first, upper horizontal water propulsion device and at least a portion of a second, lower vertical water propulsion device. The first, upper horizontal flow of water is combined with the second, lower vertical flow of water to create a third, horizontal flow of water. The resulting turbulence is lower, creating a more laminar flow and better user swimming experience. Jet bodies with side intakes may maximize capacity of the water propulsion devices.
