A water cooler is provided having a cabinet with water spigots and a door for accessing a refrigeration unit. The refrigeration unit includes a freezer compartment and may also include an icemaker. The cabinet interior contains a water reservoir which is supplied with water from a water bottle inverted in the top of the cabinet. Alternatively, the reservoir may be provided with an external source of water. In such case, an E-Coli sanitization module and a particulate water filter are provided. Cooling is effected with a compressor unit, condenser unit, an expansion valve and the refrigeration unit--all of which are interconnected with a closed loop coolant line. Predetermined segments of the coolant line are used to create freezing temperatures in the freezer compartment and non-freezing temperatures in a storage area, selected water lines and the reservoir. The condenser unit includes a condenser coil section which may be wrapped with ambient water for producing a supply of hot water. The coil section may also function to preheat ambient water that is moved to a hot water tank. The cabinet may include a pull-out section for placement of a water bottle in a lower chamber. In this case, a pump or air pressure is used to move water from the bottle into the interior heating and cooling system.
