Customer Questions & Answers

What is the efficiency of the unit?

Asked by: Rich
This is a Williams 3003622 wall furnace and the AFUE rating is 66%, which is pretty low efficiency. However, if you're only using it in the garage when you're working in there it may not matter.

Can I install this furnace in the state of Massachusettes?

Does it comply with Massachusettes regulations?
Asked by: slickster
You need a mass approval product number to see if it's been approved my guess is that it has not since we're moving away from standing pilot

What does elevation have to do with it?

The description says the unit is good up to 4500' elevation. Is this because of expected temperatures above that elevation or does it have to do with the amount of oxygen in the air? I live at 5600' in SE Arizona. Is there a different model that would work better here?
Asked by: Stoderlele
The manufacturer says that you merely have to change the burner orifice size to work properly. El Bujo 2

30,000 BTU/Hr Direct-Vent Furnace Natural Gas Heater with Wall or Cabinet-Mounted Thermostat is rated 4.4 out of 5 by 135.
Rated 5 out of 5 by from Very Nice Heater, Excellent Value I bought this heater to heat my back porch. The area I needed to heat is about 15X10, no heat run and many drafts. The heater does an excellent job of heating the area. The packaging was not the best but I escaped with no damaged parts. Installation was a little challenging but that is probably because I am not a heating and cooling person. All in all I would recommend this heater to anyone who wants to heat a good sized space that a space heater just will not keep up with. I added a programmable thermostat to knock the heat down at night and during the day when we are not around. The price is fair for what this heater is capable of...

Rated 5 out of 5 by from Nice The heater works better than expected. The blower accessory however was poorly designed for this heater. I've rotated the blower 90 degrees and now it blows heat out into the room rather than at the floor. All in all, it was a great purchase.

Rated 5 out of 5 by from A-ok so far I ordered a Williams 30,000 BTU wall heater from Home Depot. I had it delivered for an additional $99. It arrived a few days before the estimated delivery date. It was delivered while I was at work, to my covered front porch. The heater was in perfect condition after taking it out of the box. I had it professionally installed and it works great so far. I purchased it for backup heat encase of a power outage so it’s not been used very much. I have a small 1000 square foot house and it heated it very well when I tested it. It comes with its own thermostat which is nice so it will start up by itself if no one is home.
