Rated 4 out of 5 by from Warm & Toasty This equipment is very efficient. Not difficult to install. We are using it to heat four rooms downstairs and the two bedrooms upstairs. It is located in the frontroom. It doesn't blow cold air, just warm air. The rooms are seperated by walls and doors, yet there is only a 4 degree difference from one end of the house to the furnace. Very happy with the relatively quiet operation and even heating throughout the house. It has optional front and side venting that I think we will invest in later.

Rated 5 out of 5 by from Just the right size for my basement. This is a furance made by Williams. It replaced one that was the same size and manufacture that I had for 25 years. The blower moter failed and they did not have a replacement. But 25 years of trouble service is great! I think ths one will last just as long.

Rated 5 out of 5 by from Good furnace. Furnace arrived in excellent condition, was exactly as advertised. I have finished installing and testing. All is great so far. Model is standing pilot light version. Pilot is a bigger flame then I think is ideal, but that seems to be the way it is designed. Gas valve is a Honeywell valve, not one of the valves listed in the parts list but similar. Owners/install manual is pretty good. It could use some more detailed information in places. I would recommend this furnace.

Rated 4 out of 5 by from Great unit! Heater showed up and was a little dented at the bottom as other reviews have also complained about, but it wasn't that bad and I was able to bang most of it out with a small hammer. You will want to throw two things away immediately; the thermostat and the directions. It is very easy to install, but the directions make it seem nearly impossible. Thermostat is cheap and doesn't work for very well. The unit itself is fantastic. It heats the space(750 sq ft office trailer-20 degrees f outside now) quickly and efficiently and we are very pleased!

Rated 4 out of 5 by from Forsaire 40,000 BTU/hr Counterflow Heater Heater works great, was easy to install. Had some damage though, one of the fan blades was bent. Did my best to straighten but still out of balance, so probably makes a little more noise than it should.

Rated 2 out of 5 by from It works but It's over priced. It came with dents and creases. Parts were missing. I would have returned it but this is the only unit that would fit in the existing space. The damage is on the back side so it's not visible after installation. There was also a faulty limit switch but I was able to use one from the old unit.
