"This is a great unit, I installed it in my shop in a couple of hours with my 11 year old son helping me. We suspended it from the ceiling trusses and vented it horizontally out the side of the shed. When it was plumbed with propane, it lit right up. I would highly recommend purchasing this if you have a space to heat this winter."

Great Heater!!!, November 2, 2009
By 24Wins from Edwardsburg, MI

"This is a a great heater! I have a 24x26 finished garage and have had this heater now for two years. It is the most quiet heater I have ever heard and does a great job heating the garage to whatever temp we like. It has no problem heating my garage to over 70 degress in the cold Michigan winters. I have heard many other brands and they are twice as loud as the Mr Heater. Everyone that hears this heater run is very supprised. You can intall this heater upside down if needed like i did. It only needs one inch of clearance on top and I bolted it to the ceiling in the garage with the supplied hangers. Very easy to install. I would recommend this heater to everyone! If your looking for a good quiet heater, buy this one!"

Mr Heater, July 20, 2009
By heaterguy from Edelstein, Illinois

"I received the unit quickly and installed it the same day. Installation was very well detailed in the manual. I ordered all the required accessories, ( vents, gas connector), with the heater to make the installation as easy as possibele. Once in service the heater works flawlessly and keeps my shop (2000SF), plenty warm. I would recomend this heater as a good product at a reasonable price."

Cold Weather Relief, March 23, 2009
By NDCowboy from North Dakota

"I purchased and hung this heater in a 16 x 30 foot well insulated shop area of my garage. Installation was fairly easy. The extra cost for using the appliance has been less than $40 per month in our coldest winter months here in North Dakota where we stay well below zero for weeks at a time. Well worth the investment to keep my shop at about 70 degrees for the winter."
