Product Overview

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
  • Vented design ensures safe removal of impurities to keep indoor air clean
  • 8 in. hot air outlet routes air through existing ductwork
  • Air wash system ensures cleaner glass
  • Made in USA

Answer: 
After working with this stove, I think that would be fine. However, I think there may be more efficient stand alone fireplaces for this purpose. In addition, the fan is very loud, so unless you need the fan to move the air somewhere, I'd probably go with another option.

When I first placed my unit into service, I installed it in my basement and did not use my duck work but allowed the heat to rise. I left my cellar door open and the heat came up naturally. At first, it was great. But after a while, I found that the rooms in my home were not being heated evenly. I first employed a small fan to push air around, but that proved to be inconvenient as it was bothersome - but it worked fine. Now my home is only 1900 square feet and all on one level. I don't have a two story house, so heating with this unit was just fine the way it was - coming up from the cellar. After a while, I was going to cut vents in my floors to allow the heat to come up that way, but I eventually found that my duck work was 24 ga. steel and could accept the heat demands of this unit, so I'm now using my duck work. But again, coming up from the cellar allowing the heat to rise naturally, leaving the cellar door open worked great for me when I first installed my unit. When installed properly with all the safety guidelines that come with the installation manual , this unit is outstanding when providing heat for you and your family. By the way, Home Depot provides all the add-ons and black pipe and other things that you're going to need for installation. I suggest purchasing the stainless Steel chimney liner sold on line by Home depot, in addition to the top of the line black pipe that Home Depot sells on line, or in their store, called DuraVent DuraBlack, and the DuraPlus Stainless Steel Wall Thimble(s). The pictures below show what I used - however, your requirements my vary from mine, so research your particular needs before any installation. Read Less

You don't have to hook it up to a duct. For the last 3 yrs mine has been free standing with just a 90* elbow to direct the air flow. Nearby I have a floor duct where the heat rises.. During the winter my basement is usually 95+, and keeps the floors of my rancher at a comfortable 75-78.

Every stove will require different air settings dependent on your specific area, chimney, and location in the house. Some people seem to need the bottom vent opened. I do not use my bottom vent at all. Once you figure out what you need to set it at for, a long burn of 9 hours isnt out of the question at all.

Wood types and sizes have a large affect on that as well. Wood cut to all small sizes wont last as long as having some large chunks in there. You need some big ones and some smaller ones. Trial and error is inevitable.
My chimney is triple layer stainless and its 25 feet tall running up through the house. A properly setup chimney is crucial to a good operating stove. My bottom draft is always closed. When I am home I tend to run the top vent at 3/8" from closed. For overnight burns I keep the top slider about 1/4" open, almost all the way to the right.

Answer: 
Burn time is all dependent on the fuel source. If you "bank" your fire at night with split logs, you should tailor your "amount" with the desired heat range that your targeting. On the other hand if your heating during the day time and you're going to the longest burn time, again, you'll have to consider your fuel source and how you regulate your built in dampers - bottom door and top slide vent.

Burn time is all dependent on the fuel source. If you "bank" your fire at night with split logs, you should tailor your "amount" with the desired heat range that your targeting. On the other hand if your heating during the day time and you're going to the longest burn time, again, you'll have to consider your fuel source and how you regulate your built in dampers - bottom door and top slide vent. This process of keeping the firebox going can be labor intensive if you're using scrap wood, pallets and such. This stove will literally EAT fuel if you don't get your air supply right -- too much air through the bottom door will cause over heating and thus eat your fuel supply.... too little with produce smoke and ultimately line your chimney or chimney liner with a thick layer of soot and stuff. For me, this was a labor intensive learning curve on how to maximize the usefulness of my furnace. But, once I got all the bugs worked out and the right fuel source for the moment, this beauty is amazing. I use scrap wood and dried out pallets during the daytime #I'm retired# then bank my firebox at night with seasoned split oak, maple and other logs at night.
I hope this answers some of your questions - but then again, you'll have to experiment with what works best for you... time wise, heat desired - when and how much heat.

There are slots all the way across the fire box from side to side. I bought and installed mine in Oct. 2013. Has saved me wood over what my 30+ year old wood add on was using and the 13/14 14/15 winters were the worst we have had and set a lot of coldest day records.
I am burning 90% Seasoned ash and the ashes burn so fine it is almost like flour in the pan.

Yes it does have grate holes for ash to fall down into the ash tray. In fact, the firebox has a floor that has elongated spaces for firebricks that strides the elongated slots, and ash will neatly fall through when using a scraper, when gently drawn back and forth. The floor of the firebox does not have a floor that acts like a grate "shaker", similar to the old pot belly stoves. You have to reach into the firebox and use a scraper to gently work the ash down through the slots - and that's rather easy to do. The ash pan is slightly smaller than the elongated slotted spaces and some ash will miss the sides of the ash pan and accumulated on the holding floor of the pan itself. But this is not a big deal and that ash can be brought out by using the same scraper. I want to include in my remarks that if your burning wood with nails and similar things, these slots in the firebox floor are big enough to accommodate them falling through along with the ash. I live n Western Massachusetts and we can get some really bitter cold sometimes. This add-on wood burning furnace is amazing. You don't have to keep a blazing fire going all the time, just hot enough to compliment the size of you home and keep the firebox hot. The heat retention is very good and your family will stay warm. We found that balancing our utility heat with the add-on wood burning furnace is great. Although, if your not burning split logs, and just scraps of wood, keeping the fire going can be labor intensive. One last note - if you plan to burn bio-bricks, that ash doesn't fall through the grates very well. That ash is very fluffy and accumulates on the floor of the firebox, and there's a lot of it.

Answer: 
The research I did, with the same question in mind, including ask the manufacturer tech I was talking with about something else... you can run it without the fan. Keeping the doors closed keeps the oxygen flow low enough for the fire not to get too hot for the stove.

Rated 4.7 out of 5 by 131 reviewers.
Rated 4.0 out of 5.0 by This stove works great, and Englander has great support This stove is not the most efficient, and sometimes it takes a bit to get started. Also, the blower fan is very loud. However, for my purposes, it is perfect. I needed a way to heat an addition from the garage, without taking up floor space or having to haul firewood up the stairs. This stove sits just a few feet from the wood pile, and the fan moves the heater over and throughout the whole house. Also, the support from Englander was excellent. I had stove drafting issues, and Mike at their customer support taught me more about how stoves work on a half hour phone call than I could ever have learned researching it myself. October 1, 2016
Rated 5.0 out of 5.0 by England 3000 wood burning stove The stove is very well made. Good steel and I like the grate /brick layout. When moving it downstairs I was able to get a lot of the weight off the stove by easily removing the doors, bricks, grates and blower. I love the way the stove heats and the blower pushes out a lot of warmth. I like the glass front so far to see how low the wood has burned. Overall this is an exellent stove for my needs...perfect height and length for my area. Very happy with the purchase October 22, 2016
Rated 5.0 out of 5.0 by Unbeatable in the price range We recently bought this add on wood furnace. It works so well I could seriously get rid of my gas furnace. Now, they rate is for 3000 square feet. I would not say it would do an average 3000 square foot house. Maybe if your house was built within the last 10 years and is very well insulated. I am heating 1250 square feet upstairs. The furnace is downstairs and ties right into the ducting very easily. It also heats my basement too so I guess its about 2500 square feet overall. The blower pushes air through the ducting upstairs, and the basement is heated by the left over radiant heat. So happy about that, no more freezing basement. This stove weighs a lot because its built strong. We looked at the Hot Blast units from tractor supply. Those are a definite step down from what we have now. Obviously the $3000 units are probably going to be more efficient, but I am very please so far. I foresee 20 years of usage from this, and no doubt I will probably have to replace the blower and some firebrick in that time but that's understandable. March 19, 2016
Rated 5.0 out of 5.0 by I love it !!! 1 shipping on time 2 reasonable price 3 easy to install 3 keep the house warm (my house 3000 sq) 4 easy to pull out the box full of ashes. 5 enjoy watching the fire thru window . 6 i cant wait for next winter. March 19, 2016
Rated 5.0 out of 5.0 by No complaints at all! this is a very good furnace. Simple to operate and heats our 2800 ft house very easily. We've always heated with wood and have some experience in that area. We lived in Maine thru some pretty wicked weather and I wish we had had this furnace there. This is the easiest furnace ( or freestanding stove) to start a fire and keep it burning that we've ever had. It burns well and holds coals about 8 hours. I would recommend this furnace to anyone. The service department at Englander was very helpful when we called for questions January 2, 2016
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 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 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
