  • Apparatus and method for heating using microwave energy
    Patent number: 5512734
    Abstract: A heating apparatus having features of the present invention comprises a microwave energy source, a reservoir, and a heat exchanger. The reservoir is adapted to contain a flowable medium such as a liquid and is positioned so that the liquid may be heated by the microwave energy source. The heat exchanger is adapted to receive the liquid and is in communication with or coupled to the reservoir. The present invention may further include a pump for circulating the liquid between the reservoir and the heat exchanger. The liquid may be circulated using a conduit. Preferably, the heat exchanger is adapted to use at least some of the liquid heated by the microwave energy source to heat air in proximity to the heat exchanger. Also, a blower positioned near the heat exchanger may be used to direct the air heated by the heat exchanger to a desired space to be heated.
