Abstract
A water heating system for a domestic hot water tank, the system including: a heat pump adapted to provide heat energy; and a heat exchanger comprising a coil of thermally conductive material arranged such that a diameter of the coil is approximately between five and six times greater than a diameter of the thermally conductive material and the heat exchanger is adapted to be installed in the domestic hot water tank and operationally coupled to the heat pump.
Claims27
A water heating system for a domestic hot water tank, the system comprising:
- (a) a heat pump, said heat pump adapted to provide heat energy;
- and
- (b) a heat exchanger, said heat exchanger comprising a coil of thermally conductive piping, said thermally conductive piping having an outer, cross-sectional diameter of between 9.5 and 22.5 mm and being arranged such that a diameter of said coil is approximately between five and six times greater than said outer, cross-sectional diameter of said thermally conductive piping and said heat exchanger is adapted to be installed in the domestic hot water tank and operationally coupled to said heat pump.
A water heating system for a domestic hot water tank, the system comprising:
- (a) a heat pump, said heat pump adapted to provide heat energy;
- and
- (b) a heat exchanger, said heat exchanger comprising a coil of thermally conductive material arranged to transfer said heat energy from said heat pump to the domestic hot water tank so as to raise a temperature of water in the domestic hot water tank by between about 20° C. and 50° C. in approximately one hour;
- wherein said heat exchanger is a universal heat exchanger adapted to retrofit in a standard hot water tank having an opening between 70 mm and 100 mm.
A water heating system for a domestic hot water tank, the system comprising:
- (a) a heat pump, said heat pump adapted to provide heat energy;
- and
- (b) a heat exchanger, said heat exchanger comprising a coil of thermally conductive piping arranged to transfer said heat energy from said heat pump to the domestic hot water tank so as to maintain a temperature of water in the domestic hot water tank between 40° C. and 60° C. while said water is exiting the domestic hot water tank at a flow rate of between 2 and 5 gallons per minute (gpm);
- wherein said thermally conductive piping has an outer, cross-sectional diameter of between 9.5 and 22.5 mm and is arranged such that a diameter of said coil is approximately between five and six times greater than said outer, cross-sectional diameter of said thermally conductive piping:
- and
- wherein said beat exchanger is a universal heat exchanger adapted to retrofit in a standard hot water tank having an opening between 70 mm and 100 mm.
