Heating airplane hangars and shops or warehouses with floor radiant has gained popularity in the last twenty years for several reasons, it is the most efficient, productive and safest method available. If you try to heat buildings with large overhead doors by heating the air you lose all the heat every time the doors are opened. With a heated floor not only is the space warm as soon as the doors are closed but the area is even warm with the doors open. We have heated very large shops as far north as Fairbanks Alaska with very positive results.
