Rated 4.4 out of 5 by 5 reviewers.
Rated 5.0 out of 5.0 by Excellent Wall Furnace We tried working with local HVAC people put all they wanted to do was sell us a electric fireplace or a hugh wall unit. This one is small and puts out great heat and is very quiet. It does not take up a whole lot of room and so far has been very effiecinet January 13, 2015
Rated 2.0 out of 5.0 by Disappointed.... Had I seen this heater in person I would have passed as it has a "cheap" look to it, but ordering online was the only option. Mounting it with the supplied drywall anchors as instructed, they pulled through as soon as the unit was placed on the bracket. Once it was mounted & the front cover installed, only one of the two locks on the cover would actually hold it. The "built in thermostat" is a dial with numbers 1-6 ; I assumed it was actually going to have temperature settings in degrees. Programable ; on - off only, again my mistake as I thought it would be like a real thermostat and would raise & lower the temp when needed. Humidifier will likely never be used as there is no way of knowing how much water is in it & is near impossible to see while filling.... It does heat, in my space it cycles 5-6 minutes, shuts down and a minute or so later the fan starts? I would think the fan should be running as it is heating? November 1, 2012
Rated 5.0 out of 5.0 by Excellent Heater for my den I know this heater is an expensive option but it works very well in my den. I have an open beam ceiling so in the winter the room can get very cold. This heater really does the job with forced heat and slick thermostat controls. It also is fairly compact for the amount of heat produced. November 30, 2011
Rated 5.0 out of 5.0 by Safe, easy to install mini furnace I was looking for a safe reliable heater for my garage/workshop. I did not want an open flame non vented unit like the "blue flame" style units. While those have a more attractive price I researched these Williams direct vent units and they are the more safe and reliable option. It was very easy to install. Drilling the two inch intake/exhaust would be your most difficult thing to do for the installation if your not a handy man. The mini furnace heats my garage to over 80 degrees in northwestern pa.
