The object of this study was to compare economically a solar system for greenhouse conditioning in order to maintain the greenhouse air temperature at 12?C at night during the coldest months with a conventional heating system. The solar system consists of a polypropylene capillary heat exchanger; it also has two batteries of plaits respectively suspended in the air and buried into the ground of the greenhouse. This recovered energy is then stored into the greenhouse ground through the buried exchangers. The conventional heating system used in this comparative study is a 15 kW fuel boiler. The results show that the solar system was less powerful than the conventional system.
