Top of the line oil furnace has plenum on bottom to hook into duct work or you could build a plenum so it could blow hot air into a shop on to the floor.. I had it in a 55 ft. trailer house with duct work. I also have a 275 gallon oval fuel tank and thermostat, oil filter & thermostat wire. For $ 100.00 to go with it. The height is 57 inches but would be taller if a custom plenum had to be used
