40,000 BTU/hr Forsaire Counterflow Direct-Vent Propane Gas Wall Furnace Heater is rated 3.5 out of 5 by 22.

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 4 out of 5 by from Ordering and pick-up through Home Depot was easy. Delivery... Ordering and pick-up through Home Depot was easy. Delivery was quite fast. However, furnace installation was complicated, because of the safety issues that are required by the town where I live. It took longer to obtain the required permits than to order and receive the furnace from Home Depot. I was doing my own installation, and permits are a necessity to ensure safe installation and home insurance coverage.

Williams would only replace valve, not the labor to repair it. HVAC installer said it was a terrible design, took several hours to replace the valve. Do not buy, it's junk. Also, impossible to replace the thermocouple when it goes bad.
