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

  • Air wash system ensures cleaner glass

Customer Questions & Answers

Would I have too hook into my duct work or could I set it up in my basement and allow the heat to rise?

Asked by: Matthew
Duct work will be more efficient and comfortable, but independent will work. If you are running it independently I would run an 8" duct to a vent up stairs.

Could you vent this into your warm air duct work and use the furnace fan, or does it have to be vented into the cold air return?
Asked by: jpit
The ideal is for this to be ducted into the hot air duct.. if I read the manual correctly... and it makes sense this way. You'll have to figure out some way for the stove to get the air though.... either from the return duct opening, or from the house.... I use the stove without a furnace.... duct runs out to to vents.... then there are two more that just open into the room where the stove is and act as the air return.

How long is the max burn time? Will it burn through a night?

What is the max burn time?
Asked by: Don
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. I've had usable coals up to 12 hours. I was impressed. 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.

Does the firebox have grate holes for the ash to fall down to the ash tray or does the ash have to be scooped from the firebox?

Asked by: Lumberjack
Yes it has slots between the firebrick on bottom to fall through

This has been operational inside of our 2100 sq ft greenhouse for about a week. We set it indoors about 25 inches from our metal north wall. Two foot from stove we placed an elbow that runs directly outdoors to a cleanout/vertical pipe. The pipe runs about three foot above the eave of the greenhouse. Thus far it is performing well. We fill it about every 5-6 hours wth locust/hedge wood; although it will provide heat up to 8 hours. Our goal is to maintain gh temps at 55-60 at night, using two of these furnaces, with outdoor temps down to 20 degrees with 20 mph winds or less. Beyond that, I suspect we will need to supplement a bit with propane. (or electric heaters once we have our home-made powerwalls/solar in place) Hope this helps.

Rated 4 out of 5 by from would buy again I load this wood furnace 3 times a day and it keeps my house around 72 degrees. It is very easy to keep clean and did not take long to figure out how to adjust to keep the temperature fairly consistent. The only problem that I have is that the blower isn't as strong as I thought it would be. That could be how I had to hook it into my ductwork. Overall, I'm very satisfied and would buy again.

It is the sole source of heat in my shop. It puts out plenty of heat, and I like the fire-viewing window. I think it will work out nicely. I had some trouble installing the thermostat. There is not enough clearance around the hex-head screws for a socket or a wrench. They need to provide allen head screws or some other type of screw-driver compatible screw. You will need a chimney thermometer to monitor burn temperature and black stove pipe to connect this stove. Home Depot does not stock these items. Lowes does. I have been burning kiln-dried wood scraps, mostly fir and southern yellow pine. A full load of scrap lasts less than an hour at full draft. I hope real firewood will last longer, but I want to use up the scraps anyway. Some of the scraps have been outside and are wet, I have to open the bottom draft to keep the temperautre up when the wood is not fully dry.

Rated 4 out of 5 by from Great stove Bought this stove because a few friends of mine own one ... simple to use and good 8 hour burn time. Only issue I had was 2 weeks into it the thermostat started to stick . Of course it was when the temperatures started to get cold outside. I called the manufacturer directly and try overnights me a new one at no charge and have had no problems since!!!

Rated 5 out of 5 by from The beast Best value for your money!! Really puts the heat out, 25 out 78 in 2200sq foot house. Excellent craftsmanship, look at the weight compared to other stoves about 100 pounds heavier and 1000$ cheaper.
