9-10. (canceled)

12-15. (canceled)

The system of claim 15, wherein said condenser comprises a duplex condenser having a first tube in fluid connection with said refrigerant loop and a second tube including said water inlet and water outlet for flowing water therethrough, said first and second tube being thermally coupled.

The system of claim 15, wherein said at least one condenser comprises a first and second condenser both in fluid connection with said refrigerant loop, said first condenser providing said water inlet and water outlet for flowing water therethrough or proximate thereto and said second condenser having a path for flowing said cooled and dehumidified air therethrough.

21-25. (canceled)

The method of claim 24, further comprising the step of switching between said transferring step and said heating step.

The method of claim 24, further comprising the step of transferring heat from said heated water for heating air to space heat an enclosed volume.

(canceled)

A method of heating water in gas hot water tanks using heat supplied from dehumidifiers, comprising the steps of:

• providing a gas water tank including a central vent pipe and a dehumidifier comprising 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;
• placing said first condenser of said dehumidifier inside said central vent pipe, 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.
