Abstract
A method and apparatus for heating water in a spa which has a plurality of venturi jets, a hosing which includes a plurality of venturi jets and a high speed pump which circulates water through the housing and the venturi jets in the spa and a water thermostat. The thermostat is positioned in the water of the spa and connected to the high speed pump such that the high speed pump is activated to propel water through the venturi jets at high speed and thus heat it whenever the water temperature falls below a preset level.
Claims2
In combination:
- a spa which has a plurality of venturi jets, a high speed pump which circulates water through the venturi jets, and a water thermostat, the water thermostat being coupled with high speed pump such that the high speed pump is activated whenever the water temperature falls below a preset level;
- a housing having an inlet and an outlet, the inlet communicating with the high speed pump and the outlet communicating with the venturi jets;
- and
- a plurality of venturi jets positioned in the housing between the inlet and the outlet such that water flowing through the hosing must pass through the venturi jets, whereby the water is heated.
A method of heating water in a spa which has a plurality of venturi jets, a high speed pump which circulates water through the venturi jets, and a water thermostat, comprising the steps of:
- connecting an auxiliary unit between the high speed pump and the plurality of venturi jets of the spa, the auxiliary unit being comprises of a housing having an inlet, an outlet and a plurality of venturi jets positioned between the inlet and the outlet such that water flowing through the hosing must pass through the venturi jets;
- and
- connecting the water thermostat positioned in the water of the spa to the high speed pump, such that the high speed pump is activated to propel water through the venturi jets at high speed whenever the water temperature falls below a preset level.
