Radiant heating of greenhouses using radiant tubes and gas combustion

, : Radiant heating of greenhouses using radiant tubes and gas combustion. Colture Protette 16(1): 57-66

A description is given of an American Co-Ray-Vac gas radiant tube heating system for large greenhouses; it burns methane gas and has an efficiency level of > 90%. The system, with a heating capacity of 80 kW, has been installed in an Italian 1020-msuperscript 2 greenhouse. The advantages of the system include uniform temperature levels throughout the house (depending on the positioning of the burners and heat reflectors) and lower energy costs than traditional heating.
