The WoodMaster AFS 1100 furnace uses wood pellets, corn, small grains and other materials to heat multiple buildings, including a home, garage or workshop, pool, spa, greenhouse or commercial structure.
AFS 1100 specifications:
Emissions below U.S. EPA standards
The WoodMaster BioFuel furnace produces average emissions rates below standards set by U.S. Environmental Protection Agency (EPA).1
1EPA’s new emissions test guidelines announced January 29, 2007, as Phase 1 of its Outdoor Wood-fired Hydronic Heater (OWHH) Program to promote manufacturing and sales of cleaner outdoor wood furnaces
No fuels enter the house to limit smoke, soot, fire hazards and the risk of dangerous carbon monoxide buildup
The power of pellets
Wood pellets are 100% sawdust, a by-product from furniture makers, saw, paper and other mills, and otherwise destined for landfills. The sawdust is compressed and formed into 1/4-inch diameter cylinders and packaged in 40 lb. bags.
Heat transfer design draws more heat from burning a comparable amount of corn, small grains or wood pellets than competitive furnaces
Digital Electronic Temperature Control (ETC) is one center for operating temperature settings, blower, reset, water level indicator and nightlight in an easy-to-read display.
We have afs 900, not even 10 years old…lucky if thing runs for a month consistently….constantly has parts going out, wiring doesn’t hold up…insulation cracks off because of heat, always having to repair, overall thing is a giant piece of junk…has had problems since day one. It would be in anyone’s best interest to buy any other brand, woodmaster does not offer any aftermarket replacement parts, very few parts dealers, cannot find parts online unless purchase directly from woodmaster, although parts are made by different companies…but woodmaster offers no specs, so you are forced to buy directly from them. I would give 0 out of 5 stars if it was an option.
I’ve been running an AFS 1100 for close to ten years now. I heat about 2800 square feet plus domestic hot water. I’ve burned corn, pellets, and pellet/cherrypit combination. It’s the only outdoor boiler I’ve ever had so I don’t really have anything to compare it to. While I’ve been happy with it, it’s not for the person who expects it to run in a “set it and forget it” mode. It does take some fussing from a maintenance standpoint. I’ve had to replace the draft motor a couple of times and the main burn tray augers a couple of time as this sucker burns *hot* and eventually breaks the augers down to where they just snap. I’ve also added some tweaks to it myself like a hopper vibrator to shake down the grain as it feeds. With pellets especially the stove would run out of fuel and go out when there was still the equivalent of a bag and a half or so of pellets. The pellets would kind of “stick” to the sides of the hopper and not drop down. The vibrator jiggles them loose as it fed. All in all, I’ve been pretty happy with it. I wish I hadn’t had to install it so far from the house (200 feet of underground PEX) as I get a lot of temperature drop. I think I’m going to try a different heat exchanger too. I went through 20 tons of pellets the winter of 2013-2014, but it was *really* cold in Michigan that season. I figure I still saved at least $2K over the cost of propane for my 100+ year old farmhouse. If anyone has one of these and wants any suggestions, with the time I’ve had this I’ve become pretty knowledgeable.
Bryice what make and model did you install and would you do it again
We purchased a corn/ pellet outdoor furnace 3-1/2 years ago. This was supposed to simplify our heating heating needs unfortunately we are constantly having to replace augers, motors, etc. And yes we do clean it weekly and empty the ash pan daily. While the heat is noce it has been 1 headache after another. The replacement parts are costly and time consuming to install besides the days you go cold replacing them. While this was a nice idea it has turned into a nightmare. At this point I wonder if it would of been easier to keep our indoor wood furnace and put the labor into harvesting wood. I am not exaggerating or being “Over the Top”. Just honest!!!!
