A study was performed in an industrial hall heated by several propane radiant heaters located all around the hall at mid-height. The purpose of the study was to determine the advantages of this system when compared to convective heaters, and to determine its limits of application. For that purpose, a minimum instrumentation was installed in the building. This includes an automatic data logger, recording indoor temperatures, moisture content, and meteorological data on site. The energy consumption was manually recorded each week.
