Well after a long time of thumbing through the thousands of great projects and looking at several posts of ventilation fans, I decided to share my twist on the project. I originally built this box for a belt drive fan which didn’t last long. I replaced it with a direct drive smaller fan taken out of a furnace. I later added a high and low speed switch but I decided it was still missing something. This time I decided to use the extra room inside the box to include a little 1500 watt oil heater that just happened to fit perfectly. I design this type of equipment on a much larger scale for a living but not made of plywood of course. So I decided I might as well make my shop a little heating unit. At least now I don’t have to trip over that little heater anymore. I still need to slap a little paint on it and make it a little prettier but it is functional and that is what matters most.
