GREENHOUSE HEATING SYSTEM

摘要

A readiant heating system for a greenhouse (10) utilizing radiator tubing (4 0, 42, 44) formed from substantially gas im- permeable plastic material. The system includes a radiator tube (40) dispose d overhead and formed from light transmitting mate- rial so that sunlight projecting into the greenhouse will be substantially transmitted to the plants grown thereunder and a second radiator tubing (42) disposed proximate the greenhouse floor and formed of similar plastic material. The radiated tubes are inter- connected at one of their ends and a burner (20) communicates through manifo ld connected to the other ends of the radiator tubes to transmit a heated effluent through the tubes. Valve means (34) and exhaust means (82) are associated with the manifold.
