Patent ID: 8572769

Claim:
A spa for use in cold weather and hot weather conditions comprising: a spa cabinet; a water containment vessel adapted to contain water, the water containment vessel being manufactured from a heat-conducting material, the water containment vessel being supported in the spa cabinet such that an air space is formed therebetween; and a thermoelectric apparatus connected to the air space around the water containment vessel wherein the thermoelectric apparatus further comprises inner and outer thermal sides capable of heat absorption and heat dissipation, wherein when a current is applied to the thermoelectric apparatus with a normal polarity, the inner thermal side extracts heat for cooling the air in the air space and the outer side dissipates the heat outside the spa cabinet, wherein the heat is extracted from at least the heat-conducting material of the water containment vessel and the water contained therein for cooling the water to the desired temperature; and wherein when the current is applied to the apparatus with the reverse polarity, the outer side extracts heat from the environment outside the spa cabinet and the inner side dissipates heat for heating air in the air space for transferring the heat from the heated air to at least the heat-conducting material of the water containment vessel for conducting heat therefrom to the water contained therein for heating the water to a desired temperature.
