I have been looking for quite some time for a heater to heat a 350 sq ft room in my garage. My specifications are something that is inexpensive & does not have a blower. Well I found something that may fit the bill but I'm not sure exactly what it is. What is a Radiant Process Heater? This one is 30" long, 2200 watts, & runs on 110v. Is there any reason that I could'nt use 2 of these to heat a room?
