  Conventional heating methods for agricultural houses, for example, are mainly operated by a boiler powered by heavy oil by supplying power from a commercial power source, which increases the equipment cost and the running cost. It imposed a heavy burden on the person.

  Patent Document 1 discloses a device for generating hot air for house heating and generating electric power, and is provided with a conventional house heating hot air fan, a Stirling engine, and a generator, and as a heat energy for driving the Stirling engine, for a house. A heater (heat exchanger) is inserted into the combustion chamber of the hot air heater, receives a part of the high-temperature combustion gas in the combustion chamber, and uses this to operate the Stirling engine. There is disclosed a house heater used for heating a greenhouse for plant cultivation used in agriculture, which is configured to rotate the machine to obtain electric power and use the generation loss as heating for the house.

  However, even in the case of the house heater of Patent Document 1, it is configured to operate a boiler and further a Stirling engine, and as in the case described above, the equipment cost is high and the running cost is also large. It is a big burden.
