Swim spa jet propulsion systems and methods

A system for circulating water in a swim spa comprising:

• a recessed chamber formed in a shell of the swim spa, the recessed chamber defining 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 water propulsion device comprising a first water propulsion body, the first water propulsion body being directed in a horizontal direction to create a first, horizontal flow of water having a first turbulence, the first water propulsion body having an inlet end and an outlet end, the outlet end in fluid communication with the recessed chamber, the first water propulsion body having at least one intake opening between the inlet end and the outlet end, the at least one intake opening to allow stagnant water to be pulled into the first water propulsion body through the at least one intake opening and pushed out into the recessed chamber through the outlet end of the first water propulsion body;
• the second, lower vertical water propulsion device comprising a second water propulsion body, the second water propulsion body being directed in a vertical direction to create a second, vertical flow of water having a second turbulence;
• and
• wherein the second, lower vertical water propulsion device is positioned below the first, upper horizontal water propulsion device, such that the second, vertical flow of water combines with the first, horizontal flow of water to create a third, horizontal flow of water having a third turbulence, and wherein the third turbulence is less than the first turbulence and less than the second turbulence.

A method for circulating water in a swim spa comprising:

• providing a recessed chamber formed in a shell of the swim spa, the recessed chamber defining 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;
• creating a first, upper horizontal flow of water having a first turbulence;
• creating a second, lower vertical flow of water having a second turbulence;
• and
• combining the first, upper horizontal flow of water with the second, lower vertical flow of water to create a third, horizontal flow of water having a third turbulence, and wherein the third turbulence is less than the first turbulence and less than the second turbulence.
