Description of the Related Art In a building with a large number of gas appliances such as a building in which many restaurants are housed, an apartment house, or a hotel, etc., a large amount of gas is installed by using the gas appliances installed in the kitchen. Exhaust heat is generated. These exhaust heats are generally collected by an exhaust hood installed on the upper part of each gas device, and are exhausted to the outside as they are through an exhaust duct by an exhaust fan. Moreover, even if a small amount of heat is generated from each gas appliance, these waste heat becomes a large amount of heat by collecting, and since it is heat that is constantly generated on a daily basis, it has high utility value. Even though it is conceivable, it is currently discarded without being used.
