Abstract: A system for killing pests in an affected area of a structure comprises a heat exchanger unit placed within an affected area, and a thermostatic control. The heat exchanger unit is configured to receive a flow of water from a faucet, and generate heated air by transferring heat from the flow of water received from the faucet to air flowing through the heat exchanger unit. The thermostatic control is configured to monitor a temperature of the flow of water as it is received by the heat exchanger unit, monitor a temperature of the air as it is received at an inlet of the heat exchanger unit, and automatically cease the flow of water to the heat exchanger unit when the temperature of the air received by the heat exchanger unit is greater than the temperature of the flow of water.

Abstract: A method for killing pests in an affected area of a structure, comprises positioning a heat pump unit within an affected area of the structure, coupling a first end of an inlet hose to a faucet, and coupling a second end of the inlet hose to an inlet port of the heat pump unit.

Abstract: A method for killing pests in an affected area of a structure includes receiving a flow of water from a faucet, wherein the faucet comprises one of a shower faucet and a sink faucet and the temperature of the flow of water is at least 45 degrees Fahrenheit. The method continues by generating heated air using a heat pump by transferring heat from the flow of water to air, and emitting the heated air into an affected area in order to raise the temperature of the affected area to a target temperature greater than 120 degrees Fahrenheit. The method concludes by monitoring a temperature of a flow of water as it is received and, automatically ceasing operation of the heat pump when the temperature of the flow of water is above a predefined limit.
