Mr. Heater 20,000 BTU Vent-Free Blue Flame Propane Heater is rated 4.7 out of 5 by 131.
Rated 5 out of 5 by from Very good and efficient! We were running a similar heater in our home previous to purchasing this one. We use it as a stand-alone heater with a small tank, rather than as wall mounted unit piped into outside propane tanks. The unit gives off great, steady, reliable heat, and is so very easy to use. The only thing that I would want people to be aware of is that this is not a plug and play unit. You must purchase the correct hoses and fittings to use as a stand-alone, as a wall mounted unit, I can't say, but it did come with a fitting that I could not use in my setup. If you are not familiar with propane lines, TAKE IT TO A PROFESSIONAL TO SET IT UP FOR YOU! Once your setup is completed, you will enjoy warmth dwarfed only by the old fashioned fireplace and hearth. I absolutely reccomend this heater. It runs so cheap and efficiently, that I and my wallet couldn't survive without it. It's well worth the purchase price.

Rated 3 out of 5 by from Good price We bought this for our basement. When installing it, one of the pipe connections cracked (not our fault, we were literally hand tightening it and it cracked in two. Obviously there was a manufacturing defect to it) and we had to take it back and exchange it. The new one had no installation problems and it works fine. Only issue is, there seems to have a propane smell to it. We checked for leaks and didn’t find any, so hoping the smell will go away the longer we run it.

Rated 5 out of 5 by from 2nd Heater Purchased! The 1zt one we bought, lasted over 10 years. We recently purchased the 2nd one because we have enjoyed using the 1st one in office and de ided to put on on the "mancave".

Rated 4 out of 5 by from Everything claimed is correct. We had an older Mr. Heater 30000 BTU heater that was too big for our square footage. We opted for the 20000 BTU and we now have a more consistent temp and were saving propane. This is our only source of heat in our tiny house. Our only issue is our older unit had a relatively flat face that fit our mounting area and the new unit has a rounded face area. It looks nicer but does not fit our area as nicely.

Is this 30,000 BTU or 20,000 BTU? Under the Specs it shows: 20,000 BTUs In the name of the product it says 30,000 BTU

Asked by: The German Grappler
All vent free are available in 10, 20, and 30 thousand btu units. The part number is the key to knowing what is in the box or the model number. There will be only a 10 20 30 in the model number. So it sounds like you are getting a 30 btu unit. Call us if you need further help. Rich Mr Heater

Will it operate off of a 250 gallon tank

They will with the right connections. Technically our heaters are designed with 20 and 40 pound containers in mind.

How difficult are they to install for a fairlyvadept layman?

Asked by: Hal51
Pretty much if you can turn a screw you can install a vent free heater for the wall or floor. The "feet" are attached by screws. Rich Mr Heater
