PacTrio 1200w Ceramic Heater with 300 CFM 3-Speed Portable Evaporative Cooler option suitable for 150 sq. ft.

A:  It really depends on the size of the shop and whether or not the door is frequently opened and closed. The heater in this unit can heat and maintain comfort in a space approximately 150 sqft. hence space about 10' x 15'. If the door is frequently opened and closed, that will allow some of the heat to escape, so that door frequency is crucial. I'm afraid this heater might be a little undersized for your application such that without the actual dimensions of your shop, it is hard to determine.

A:  Evaporative coolers are "one pass systems" meaning the air can only be cooled the first time through. Hence the humidity will eventually build up, the space will become humid and the efficiency will plummet if no fresh air is available. On the other hand, since this is a small, single room evaporative cooler, it does not require much fresh air. It is a perfect "spot cooling" alternative to a fan and if you need a small amount of relief in a room that gets too much sun, but you do not want to turn down the A/C in the entire house, this will work perfectly for you. 5 months ago
