ABSTRACT:
A system for providing heating air bubbles to a heated tub or spa positioned within a heated water circuit having heater and pump means. Included is an ambient air input conduit including a blower. Also included is a heat exchanger positioned within a fluid integral closet, the heat exchanger having a central fluid transfer coil and heat sink in thermal communication. The heat sink projects outwardly within the interior of the air closet, the air closet having as its input an output of said ambient air input conduit, the fluid transfer coil having as its input and output a by-pass of the hot water circuit. Further included in the system is an internal air conduit having as its input the output of said air closet and, as its output, the heated spa or tub. As such, the passage of heated water through the fluid transfer coil of heat exchanger will heat the heat sink means of exchanger to, in turn, communicate heat to the ambient air furnished to the air closet which, in turn, through the internal air conduit provides a heated air bubble input to the heated spa or tub.
