I have provided two personal photos to show size. I am satisfied with this heater but beware that most states, including mine (MA), prohibits vent-less heaters as primary sources of heat and should only be used as supplemental.

With that said, please be aware that although this product is 99.9% efficient, the unit does give off a smell. The gas by-products that are burning off into the air make the .1% and it is important to keep one window cracked 1 inch.

I have a 1000 square foot apartment, and this year (December 2012) temperatures have dropped below 32 degrees a couple of times and this heater has more than done its job. It is extremely warm and very nice to look at with the blue flame and compact size.

This model does NOT have a digital reading of the temperature despite the product image description. I did purchase an indoor digital thermometer along with a carbon monoxide detector for safety, it has not detected any levels of carbon monoxide. It does come with a kit to either mount it to the wall or have it free standing.

I spent over 5 months researching gas heaters before buying this one, and am overall very satisfied with the physical and mechanical performance.

I did have to call customer serviced a couple of times with questions and they were not only helpful but there weren't any wait times.

Great heater! We had a Williams brand wall heater that failed on us. If we were to fix it , it would have cost us around $150 just to buy the pilot for the old heater SO we decided to try this product. Note that the one we bought does not require vent, blue flame, natural gas. The blower fan blows the heat from the unit towards the room it helps make the room heat quicker and it helps keeps the unit and the things close to it reasonably cool. Also we got the blue flame coz we read somewhere that the yellow flame gives out radiant heat (not sure). The 20k btu heats up a 20-30 degrees 700 sqm (approx) fairly quick. I would buy this product as a gift or recommend it to others.

I mounted this on the wall of my basement shop and I set it and forget it. I have an old thermostat that I use to monitor the temperature and it stays a constant 72F. The flame modulation feature works very well. The 2012 winter is very mild, but I am still glad I got it. This is a quality unit.

Honest reviews on Mr. Heater 20,000 BTU Natural Gas Blue Flame Vent Free Heater

I am pretty happy with the heater, but I have run several tests on the blower fan ... and I can't even tell a 1 inch difference in whether the fan is on or off.

I hear the fan running, (and I can see the blades moving) but it does not blow into the room (not even one inch more than if the fan is not on) I am beginning to think the fan blades have no significant pitch to them ie they just spin but do not move any air forward.

Installation was simple. This unit may be small but very powerful AND efficient. It heats not only my basement, but the heat rises and also heats my large kitchen. Love it!
