Water circulation apparatus for use in a spa or the like utilises a turbine or axial flow pump for pumping the water from a water inlet to the jets or other exhaust openings within the spa and under the water surface. Cooling air from ambient surroundings is used to cool a motor providing power to the pump. The motor and pump are located within a component compartment and exhaust openings exhaust the cooling air passing through the motor where it may be used for heating towels. The component compartment may be sealed thereby to allow heated air to escape only from the exhaust openings.

1. Cooling apparatus for cooling the motor of a water pump within a motor compartment, said motor having windings, said cooling apparatus comprising an air inlet member for obtaining cooling air from a source of relatively cooler air outside said motor compartment and passing said cooling air to said motor through a duct extending from said air inlet member outside said engine compartment to said motor, a fan within said motor to convey said cooling air from said duct through said motor and over said windings, an exhaust outlet from said motor to allow said cooling air to exhaust from said motor and at least one vent member to allow said cooling air conveyed from said exhaust outlet of said motor to exhaust to said ambient surroundings.
