交換機構を用いても良い。In FIG. 1, the hot water that has been heat-exchanged by the bubbling device 2 is introduced into the greenhouse 10 through a pipe and used to raise the temperature of the greenhouse air and plants. It is said that the rate of photosynthesis of plants and the respiration rate at night depend greatly on the temperature together with CO 2 gas, and the rate has a peak at a greenhouse temperature of 25 to 40 ° C. Therefore, when the temperature in the greenhouse is lower than the optimum temperature for plant growth (25 to 40 ° C.) as in the winter season, the horticultural plants are poorly grown, and many harvests cannot be expected, and when they are severe, they die. Therefore, the temperature control (heating cost) in winter is a great economic burden for the horticulturist, but in the present embodiment, by using the hot water at the time of bubbling as the heat source for heating, the heating cost in winter can be saved. . A heat exchange mechanism using cooling fins or tap water may be used as the exhaust gas cooling means instead of the bubbling.
