One by-product of the boiler is CO 2. This gas can be trapped and delivered into the greenhouse to help the plants in the photosynthesis process. The warm water or steam must be transported in pipes throughout the greenhouse. The water temperature for overhead systems can be up to 200F (94C) while the water under the benches can be up to 104F (40C). Floor heating is another method to heat the greenhouse with hot water.
