Water-heating dehumidifier

A water-heating dehumidifier, comprising:

• a gas water tank including a central vent pipe;
• a refrigerant loop including a compressor, a first condenser and a second condenser both in fluid connection with said refrigerant loop, an expansion device and an evaporator including an evaporator fan,
• wherein in a water heating mode air is drawn by said evaporator fan across said evaporator to produce cooled and dehumidified air and heat taken from said air is absorbed by said refrigerant at said evaporator and pumped to said first condenser, said first condenser having a water inlet and a water outlet for flowing water therethrough or proximate thereto to heat said water, said second condenser being an air-cooled condenser having a path for flowing said cooled and dehumidified air therethrough,
• wherein said first condenser has single wall insulating tubing thereon and is affixed to said central vent pine, said insulating tubing together with said central vent pipe providing double wall protection for refrigerant-to-water heat exchange occurring in said water tank.
