40,000 BTU/hr Forsaire Counterflow Direct-Vent Propane Gas Wall Furnace Heater is rated 3.8 out of 5 by 17.

I am the proud owner of a Williams 40,000 BTU/hr propane wall furnace heater. I am a retired electrician and I installed the unit myself. I have pipe cutting and threading tools and a little knowledge. The installation was easy. The unit worked well the first time I fired it up. I really like the air intake and exhaust system which exits the unit from the back and is designed to go though an exterior wall. We primarily heat our home with a wood stove. My wife and I wanted a heating system other than wood heat. Getting fire wood for the winter season has become more difficult as we have aged. This season will be the first season that we will use the furnace. I expect the unit will meet all our expectations. Our living room area is about 700 square feet. The 40,000 BTU/hr furnace is rated to heat 1,400 square feet. We should be cozy warm. With a fan, I think, we can blow warm air into the kitchen and pantry area.

Rated 3 out of 5 by from Dented It's hard to open this at the store. Outside of package looked fine. When we opened it the unit had dents all over it. As if someone dropped it off the truck to move it. We haven't finishing installing and will be seriously bummed if the unit has broken parts inside. We have a highly skilled licensed plumber installing it. He said not the best instructions or access to the piping areas but we are installing in wall which might be why it's harder to reach. Photo is of dent AFTER we tried fixing it. Lucky for us it's the side facing into corner. The vent plates also damaged. Needed to bang those out just to get them on.

Very pleased with the unit, heats our 1200 sq ft basement apartment efficiently. Was not happy that the first one showed up damaged and had to take it to the local Home depot when it was delivered to my house. Home depot should have stepped up and ordered the new one and had it delivered to my house and pick up the damaged one. Luckily I have a minivan and was able to load it up with someones help. So..other then having to pay to have it installed 2 times, I am happy with the unit.
