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
  • Air wash system ensures cleaner glass

Rated 4.7 out of 5 by 105 reviewers.
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 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 4.0 out of 5.0 by Great price Received shipment of this wood furnace on Friday afternoon October 11th. Off loaded it to my small flatbed trailer to uncover and inspect before the trucker left. It was in good condition, the trucker told of one he had delivered on Thursday that was pretty beat up. I took it to where I had a brush pile, added a bit of stove pipe to the flue system then built a nice fire in the furnace. I let it burn all night Friday and almost all day Saturday to burn off any oils and paint so the fumes would not be in the house. The owners manual says to open the windows to allow the home to air out while it is burning the first time. I am glad I took that step as I had black smoke rolling out the air draft vents and white smoke come out around the fuel fill door. I spent Saturday removing my old 28 year old wood furnace which was a lot heavier than the England. I got the England in the basement Saturday afternoon late. Monday I got new flue/stove pipe to hook it up to my chimney. I also at that time bought some 8 inch pipe to hook up to my heating ducts, the old furnace had a 12 inch transfer pipe. First fire in the home went well with just a little bit of fumes from the new flue/stove pipe, smoking around the doors was gone too. Starting a fire in this furnace is strange to me as I am not used to leaving the fuel door open for a ½ inch up to 20 minutes. I do it as the owner’s manual says to. Is going to take some getting used to. I was worried about this furnace not having a shaker grate as my old one didn’t either. For 28 years I have let the fire burn out then used a round shovel to take the ashes out the fuel input door as trying to poke them thru the grates was a royal pain in the kister. The grate is so much better in the Englander the ashes just about all fall thru when they have been burnt to dust quality. I do wish the ash pan had a center fold down handle to ease the removal till you can get to the handle in the rear of the pan. I will probably make one for it. So far after having a fire in it for over two weeks I am happy with the unit. I haven't even ran the fan except to make sure it worked. It is supposed to heat an area much greater than units costing 2 to 3 hundred dollars more. I can’t wait to get some real winter weather to see if it lives up to the 3000 sq. ft. heating capability. I have been getting by with loading it twice a day at this time with well-seasoned Ash. I would rate this at a 5 except for the opening windows in the house part in the owner’s manual. They should tell people to fire it up outside for the first time I believe. I also wish it had a optional stand or legs of some sort. At just 6 foot I find it lower than my liking to fill with wood and take the ash pan out. I think putting it on concrete blocks even in a basement furnace room tacky. As for the window in the door, At first My wife had to keep checking to make sure there was no fire outside the stove as the old one didn't have a window. I can take it or leave it. November 4, 2013
Rated 5.0 out of 5.0 by A great furnace at a great price The wood furnace works very well and was easy to install. I hooked it into my existing hot air plenum and it took me about 4 hours total to install. I've been using it for 3 years now and have been very happy with it. It is a bit noisy so I wouldn't install one in your living space but the basement is fine. October 9, 2012
Rated 5.0 out of 5.0 by Great buy! I bought this stove a month ago. I am new to the wood burning life, so I cant compare it to anything but this stove is everything I was expecting. Took the advice of some other reviews and made my first fire outside. That was some great advice, it smoked like crazy for about 20 mins. I let it burn out and cool down then took it all apart to make it easier to get into my basement. Hooked it up to my old duct work. Got a fire going, and then had to open all the windows in the house because it was 80 degrees. My house is 1500sqft and this stove heats it with out even trying. I am going to run a new duct to the garage soon that is why I went with a big stove. Overall I love this stove so far. October 14, 2014
Rated 5.0 out of 5.0 by dont believe the lower reviews!! this stove heats like none other!! I have had this stove for 4 years and it heats my 3500sqr ft house with ease.I just read some of the low rating comments and clearly those people are doing something wrong.This stove cranks out heat!! I have mine set up as a stand alone stove not added to my ductwork.I put an elbow on the blower out vent and have the blower plugged into a variable rate switch wich allows me to adjust the blower from half speed to full blast.My furnace has been disconnected for years and this is my sole source of heat,thats how good this thing is.I burn pallet wood when Im home and cordwood at night,stove will run for 8 hours easy!!Just like any wood stove you need to learn all its habbits.I also installed a damper in the outlet black stove pipe before the chimney to add more burn control.If you want real awesome heat,this stove has it and its got good old steel reflector inside,nun of that epa cataletic tubes that robs all your heat burn.

Rated 5.0 out of 5.0 by good investment We have a 2600 sq ft house with a full basement on wooded mountains in VA. We routinely have power outages during winter. We purchased this furnace to be the main source of heat for winter. It was easy to install, and so far has worked better than expected. I tested it on a cold snap of 35 degree weather, and with only a single blower it took several hours to warm the house but soon we were at a very comfortable 72 degrees and had to dampen it back to keep it manageable. Both the house and basement approx. 5200 sq ft were maintained at 70 plus with the furnace at half damper. The added advantage was it dropped the humidity level to a dry 45 percent in the basement. It also uses less wood than the fireplace insert we had been using and the blower runs with no problem on our limited solar back up system. The only negative is the strong industrial coating smell that burns off after the first several burnings. If you have access to wood this is a no brainer. After a full winter I'll write another review. October 7, 2014
