It's no wonder we call this the work horse of our stove family. The Add-on Furnace can hook into your home's ductwork to supplement your existing heating system, or you can dump the heat directly into a garage, shop or other large area. The large, 850 CFM blower with thermostat pushes hot air through an 8 in. hot air outlet on the top of the stove, and if this hot air is routed into your homes existing ductwork, it can heat up to 3,000 sq. ft. and we were the first to put a viewing glass on the door of our furnace, which means that you can check on your fire from the top of your stairs if it's in a basement, or from across the room if you place it in a large work area. This furnace burns wood, and was talking about big wood: the firebox accepts logs up to 25 in. L, and a huge ash pan below the firebox means that you will have ample room to collect the ash from those big logs.

  • Steel and cast iron construction offers long-lasting durability
  • Less log cutting, accepts logs up to 25 in. L
  • Heats up to 3,000 sq. ft. when fed into your existing ductwork; supplements existing furnace
  • First add-on furnace with a standard viewing glass (9 in. x 9 in.) check on your fire from across the room or the top of your stairs
  • Extra large ash pan for easy ash removal
  • Thermostat (for blower) included for easy control
  • Vented design ensures safe removal of impurities to keep indoor air clean
  • Large 850 CFM blower aids in whole-house heat circulation
  • 8 in. hot air outlet routes air through existing ductwork

Rated 4.7 out of 5 by 115 reviewers.
Rated 5.0 out of 5.0 by You won't be disappointed! I purchased this unit in July to replace an inefficient wood stove. I installed it myself and found it to be pretty straightforward. I ran the duct work to 3 floor registers that I had in place from my previous wood stove. This thing pumps out heat like crazy. starting a fire was a breeze, the blower is noticeable but it's by no means "loud" as some of the other reviews stated. I've noticed very little smoke coming from my chimney which tells me I'm getting a clean burn. My old stove smoked like a freight train. It's a chilly 43 degrees out as I write this and it's in the 80's in my home! almost time to open up a window! If you want lower heating bills, or no heating bills at all, BUY ONE! October 2, 2015
Rated 5.0 out of 5.0 by So far so good I have only been using the wood furnace for a couple weeks so far and we have not gotten to the really cold weather yet but it is lived up to the hype so far. I have been able to get the house up to 75 starting from 60 with no problems. Pretty easy to install even for someone that does not have the most skills like myself. I was able to do the chimney as well as connecting the furnace to the existing ductwork. October 20, 2015
Rated 5.0 out of 5.0 by Smart purchase for us This is AMERICAN MADE, it doesn't get any better than that folks. This model was so easy to set up, along with the Dura Plus black pipe and the wood stove heat indicator (also sold by Home Depot). We have a five (5) room cape and this baby provides all the warmth we need for New England weather. Just a word of caution - it's heavy, very heavy. You'll need at least three grown men to muscle this beauty into place. Also, the learning curve for using fuel - wood, bio bricks, etc., take a while so you don't go through your fuel supply in a week. Learn how to set the bottom and top dampers along with "banking" your fire. Once you have that under your belt, you're off and running for a nice warm house. Just one more thing - be sure to follow all codes and instructions that come with your unit. The heat given off by this unit shouldn't be a hazard to flammable walls, ceilings and nearby objects. Also be advised that you'll end up cleaning out the ash draw a lot, so have a metal bucket and metal trash can available. Just be mindful of the small burning embers in the ash sometimes.

Rated 5.0 out of 5.0 by Great furnace for the basement! Buy this furnace.... The furnace has exceeded my expectations. I had purchased an epa wood stove first and I could not get the house up even 1 degree because it just did not throw enough heat. But now with this furnace, I can heat us up and sometimes have to crack a window!! It was an awesome purchase. I also added secondary burn tubes to it and it is more efficient. If interested check out the my modification on you tube. Don't go through another cold winter - buy this furnace! The blower is a bit noisy, but in the basement it is quiet enough... may not be great if you have this set up in your living room next to the TV.... not sure what the folks are complaining about... it is no louder than my oil furnace was.

Rated 5.0 out of 5.0 by Englander 28-3500 I purchased this stove for my house that I purchased in April of 2014. This house was only setup with an oil furnace. I have only started it up once, but I was incredibly impressed with how much heat this thing put out. After install, I started a fire to burn off the fumes. This did smoke up the house, but after twenty minutes or so the smoke cleared and the burn was smooth. I put in 2 very small pieces of wood on a recent 37 degree night and it kept my house at 70 until morning. I expect that this stove will be just as impressive as it gets colder. A very cool stove, easy installation, TON of heat output through the blower. Their customer service is terrific, send me 2 shipments of new fire bricks for free because mine were damaged in shipping. I was hesitant about buying such a low priced stove, but these reviews convinced me, and they were true. September 18, 2014
Rated 5.0 out of 5.0 by great furnace works great built well really heats well blower is very powerful. now have plenty of heat at the back of house ,pleased with noise level of blower quieter than my hot air furnace. fire seems to last well havent been able to run a full load hasnt been cold enough this puts out a ton of heat havent used close to as much wood as normal this time of year only reason i rated quality as good is poor fit of smoke pipe in the back fits loose and had to drill holes to be able to secure pipe with screws used high temp sealant to fill void around pipe November 9, 2015
Rated 5.0 out of 5.0 by GREAT HOT AIR FURNACE Finally installed this week with Selkirk double wall pipe, fresh air Supply. First night loaded up with well-seasoned hard maple, after 9 hours had plenty of hot coals in the morning. Not sure how some reviewers cant get an all night out of it. This is one well built furnace, hats off to Englander stove works. I wouldn't modify a thing to this stove. Do burn the stove outside like the other posts say...It smokes like crazy and lighten it by removing doors, brick and grates up before moving.(I did it myself...must be crazy) but do have a walk out basement. I will be using a wye on the 8 in hot air duct and split off to 6 in in lower duct work (which does my family room and lower office) in my central air heat pump system and 6 in into a floor register in my hall floor near bedrooms, this should cover the entire house which is a (Bi-level) with adequate heat. The 850 cfm fan kicks on and off at 125 degrees with amazing air flow. All in a great price too @ $1200 (You cant find one like this at a Fair) November 16, 2014
Rated 5.0 out of 5.0 by Great stove at a great price I've only burned a few fires in the stove, but have no complaints so far. The firebox is big so you can fit a lot of wood in there. The glass door is probably my favorite feature, I like being able to check on the fire without having to open the door. The blower seems to move a lot of air, but I have yet to really test it's ability during really cold times. Mine got a few dents near the top on the side during shipping. This doesn't affect the operation, is only cosmetic, and Home Depot still gave me a discount. October 15, 2015
