ABSTRACT:
A radiant heating system for a greenhouse utilizing radiator tubing formed from substantially gas impermeable plastic material. The system includes a radiator tube disposed overhead and formed from light transmitting material so that sunlight projecting into the greenhouse will be substantially transmitted to the plants grown thereunder and a second radiator tube disposed proximate the greenhouse floor and formed of similar plastic material. The radiated tubes are interconnected at one of their ends and a burner communicates through a manifold connected to the other ends of the radiator tubes to transmit a heated effluent through the tubes. Valve means and exhaust means are associated with the manifold. The valve means operates to selectively direct the heated effluent from the burner to the overhead radiator tube for subsequent movement through the inner connection and the floor radiator and back to the manifold for discharge from the greenhouse through the exhaust means, or to direct the heated effluent from the burner to the floor radiator tube for subsequent movement through the inner connection and the overhead radiator and back to the manifold for discharge from the greenhouse through the exhaust means. This allows for a primary heating radiator and a secondary or residual radiator in the greenhouse.
