Mr. Heater 20,000 BTU Propane Blue Flame Heater MHVFB20TBLP
Product Review (submitted on December 13, 2013):
Instant heat comes pouring out as soon as the fire is on. I believe it probably ought not be used in an area less than 200sq. feet. Fan feature is very helpfull for distributing heat especially if you have a low ceiling that could possibly get hot enough to catch fire if left on high without the fan.
**This heater could easilly heat a garage.**
Worth the money for sure.
