Add-on refrigerant boiler for electric heat pump

Claim 1

A method of supplying desired quantities of heat to the refrigerant of an electric heat pump, comprising the steps of a. positioning an electric heat pump to operate in its heating cycle, with the compressor adjusted to function as desired, b. positioning a boiler near the heat pump, c. positioning a liquid storage tank near the boiler, d. installing means of transferring heat from the fired boiler into the liquid storage tank, said means consisting of liquid transfer pipes and coils, e. connecting and adjusting at least one controllable valve to each heat pump pipe line that carries refrigerant to its heating or condensing coils and away from said coils, f. installing refrigerant heat pipe coils inside the hot liquid storage tank and connecting same to the two controllable valves, forming a loop for conveying the refrigerant through the hot liquid storage tank, g. installing a pump in the refrigerant pipe line that connects the controllable valve, installed in the heat pump refrigerant line that carries refrigerant away from its heating or condensing coils, to the refrigerant heat pipe coils located inside the hot liquid tank, said pump positioned to circulate the refrigerant from the heat pump pipe line through said refrigerant heat pipe coils in the liquid storage tank, thus picking up heat produced by the boiler burn, and back up through the loop and the other controllable valve into the heat pump pipe line that carries said hot refrigerant into the heat pump heat or condenser coils, where said heat is released.

Claim 2

A method of supplying desired quantities of heat to the refrigerant of an electric heat pump, comprising the steps of a. positioning an electric heat pump to operate in its heating cycle, with the compressor adjusted to function as desired, b. positioning a boiler near the heat pump, c. positioning a liquid storage tank near the boiler, d. installing means of transferring heat from the fired boiler into the liquid storage tank, said means consisting of liquid transfer pipes and coils, e. connecting and adjusting at least one controllable valve to each heat pump pipe line that carries refrigerant to its heating or condensing coils and away from said coils, f. installing refrigerant heat pipe coils inside the hot liquid storage tank and connecting same to the two controllable valves, forming a loop for conveying the refrigerant through the hot liquid storage tank, g. installing a pump in the refrigerant pipe line that connects the controllable valve, installed in the heat pump refrigerant line that carries refrigerant away from its heating or condensing coils, to the refrigerant heat pipe coils located inside the hot liquid tank, said pump positioned to circulate the refrigerant from the heat pump pipe line through said refrigerant heat pipe coils in the liquid storage tank, thus picking up heat produced by the boiler burn, and back up through the loop and the other controllable valve into the heat pump pipe line that carries said hot refrigerant into the heat pump heat or condenser coils, where said heat is released.

Claim 4

A method of supplying desired quantities of heat to the refrigerant of an electric heat pump, comprising the steps of a. positioning an electric heat pump to operate in its heating cycle, with the compressor adjusted to function as desired, b. positioning a boiler near the heat pump, c. connecting and adjusting at least one controllable valve to each heat pump pipe line that carries refrigerant to its heating or condensing coils and away from said coils, d. installing refrigerant heat pipe coils in the boiler and connecting same to the two controllable valves, forming a loop for conveying the refrigerant, e. installing a pump in the refrigerant pipe line that connects the controllable valve, installed in the heat pump refrigerant line that carries refrigerant away from its heating or condensing coils, to the refrigerant heat pipe coils located in the boiler, said pump positioned to circulate the refrigerant from the heat pump pipe line through said refrigerant heat pipe coils in the boiler, thus picking up heat produced by the boiler burn, and back up through the loop and the other controllable valve into the heat pump pipe line that carries said hot refrigerant into the heat pump heating or condensing coils, where said heat is released.
