Hyprotherm Manufacturing LLC is one of the leading and IS the oldest manufacturer of outdoor wood furnaces in Canada and the United States. We have been building quality wood burning  furnaces since 1972 - 47 years!

We are a family run business (privately held - no big corporations), located in North Arkansas (10 miles from Missouri) and know all about cold temperatures. We sell many furnaces in Canada, Alaska and Europe in dreadfully cold places like Romania! 

One of the reasons our prices are so low is because we are filling a need; for everyone to have an outdoor furnace, that wants one. 

 - Our labor rates are low, here in Arkansas and we pass those savings on to you!

 - Our advertising is only $300 a month - unlike others who spend tens of thousands of dollars on every full-page color ad. You pay for that!

 - We use all off-the-shelf part where possible. That means that they cost less money. We don't use expensive circuit boards or computerized parts. That means less expense for you (and simpler too).

 - No one is looking to get rich off of these furnaces. In fact some other manufactures put there furnaces on sale, lowering their prices by MORE than we even make on a furnace!

We have a simpler, nicer looking furnace that's made to stand the test of time. We use our own tried and true SIMPLE 47 year old design and based our forced-air furnace on the same firebox design (3/8" thick), energy saving/wood saving chimney design, grates, ash receptacle, draft fan, front safety door and pull-out ash tray designs.  This is the same furnace we were building in 1972 without changing our prices by using cheaper materials or giving sloppy craftsmanship.

We HAVE made improvements to the furnaces over time - and STILL have the lowest prices!

 We believe we have the best outdoor wood furnace - and certainly the best price by far. 

Simply look at the shear weight of our furnaces and you will discover that we use the most metal and have the thickest firebox of all.

What is the Hyprotherm Outdoor Wood Fired Furnace?
It is a safe and efficient way to heat your home with wood. The Hyprotherm outside wood burning furnace is designed to look like an attractive storage building and is installed outside, away from the home or building being heated. 

Having an outdoor wood fired furnace eliminates smoke, pollution, bugs and wood debris within the house. What used to be a water chamber, is now an air chamber, surrounding the huge furnace firebox and the heat is transferred from the wood fire to the air surrounding the firebox. Once the air temperature hits 110F -125F (you set it where you desire), the big furnace 2100+ CFM fan that comes on the our furnace, turn on and blows hot air into your home, into your existing ductwork. The temperature is controlled by a thermostat in your home. We have seen air and vent temperature coming from our furnace at 170 F, very similar to an oil or gas furnace output and MUCH hotter than any heat pump! There is NO NEED for a heat exchanger or piping

 

What kind of heating systems can the Hyprotherm Furnace interface with?

Only a forced air furnace inside your home, can be used. No boilers or radiant floor heating systems can be hooked up. 

However, you can add ductwork to any building (or not even use any ductwork) to heat a building.

We can even help you if you don't have any heating system now!

You can simply run a supply and return into any two rooms of your home (one to each). It is better to use rooms at opposite end or corners of the home for better air flow and more even heat.

 

How can the Hyprotherm Wood Furnace heat my home and water?
Not unless you buy our optional domestic hot water coil option for $489. Otherwise, only the Hyprotherm water BOILER  can heat your domestic hot water which is a Hydronic heating system.
What are the advantages of the Hyprotherm outdoor wood furnace?
  • - All of our parts are off-the-shelf parts. 
  • - The chance of carbon monoxide build-up in your home is eliminated.
  • - Smoke in your home is eliminated.
  • - The chance of a gas explosion from your furnace in your home is eliminated.
  • -  Indoor pollutants of harmful gases and fumes are eliminated.
  • - Asthma and other breathing difficulties are greatly helped by eliminating the dry air, fumes and gases.
  •  - Eliminates the chance of chimney and flu fires from your furnace.
  • - Lower insurance rates are usually PROBABLE!
  • - Put the wood pile beside your outdoor furnace, so you don't have to carry it inside!
  •  

    The Hyprotherm furnace removes the fire hazard from your home or building because all of the burning and stoking takes place outside. Insurance companies love these furnaces. Often lower rates or higher coverage can be had by changing from a fireplace or indoor wood stove to an outside wood furnace.

    An outdoor wood furnace also helps your indoor air quality and can alleviate respiratory and allergy problems caused by burning wood indoors. No more dark sooty walls and bugs either! Thermostatic control provides your home with even, steady heat.

    The house will be less drafty when heating with the outside forced-air wood furnace, because there is no combustion device operating inside drawing in cold outside air to replace that used in combustion.

    Current owners of the Hyprotherm Furnace are also using up to 25 to 50 percent less wood compared to other heating alternatives. Since the Hyprotherm can burn larger and longer pieces of wood (up to 14 feet on many models!) it will dramatically reduce time spent preparing the wood. NO SPLITTING is needed!

    The FORCED-AIR top loader can be found here.
    It refers to a kiln because that is what a kiln needs HOT AIR and lots of it!

    Costs for large round timbers are also dramatically less than for smaller split wood. You can get this type of wood for $70-90 a cord compared to $120-140 a cord.

    The Hyprotherm Wood Furnace means easy maintenance and few parts requiring service. You don't need costly electrical gadgets, like Smart Phone hook-up and other complications to cause problems down the road. This is a proven design of over 47 years! 

    "KEEP IT SIMPLE and efficient", is our 4 decades-old motto. 

    Can the installation be completed by the homeowner or does professional need to be used?
    Most of our customers (90 - 95%) install our wood burning furnaces themselves. Here is a photo of a lady installing her underground duct work and framing her pad with a friend's help.



    The electrical hookup is simple 110V wiring. All of our furnaces and boilers, from the smallest and least expensive to the biggest and most expensive are PRE-WIRED!

    You MAY want but don't need a heating and air guy to hook up the duct work or install a heat exchanger, but all you really need is an adapter from a round 12" pipe to your rectangle (usually) pipe on our water-less furnaces. (Shown below)

    Everything is very simple and easy to do. There is a comprehensive manual, with lots of pictures and diagrams, that will help you every step of the way. You can also call me, Ben, or the factory for assistance.

    What do the experts say?
    According to the University of Nebraska, "Wood burning stoves may not only save people money on their heating bills this winter, but also are a clean alternative to electric or gas furnaces," Adams said.

    Scott Josiah, state forester with the Nebraska Forest Service at UNL, said "There also are environmental benefits to using wood heat. Wood heat produces little pollution and is environmentally friendly, especially when wood is used in a high-efficiency wood burning stove and where firewood is a readily available resource."

     

    What is the BTU rating of your furnace?
    First of all, we rate our furnaces and boiler quite differently than most manufacturers. 

    It is usually best to look at the square footage rating. For example, we rate our ThermoWind 1000 at almost 4400 square feet. We rate our 185 water model at 5,182 sq. ft. This is for average winter conditions, like in PA and Ohio, heating a well-insulated home, burning a good hardwood like Oak.

    Customers in Wisconsin, Michigan, Minnesota and upstate NY should consider this as heating 1000 less square fee. Folks in TN, NC, Arkansas, etc, can easily heat 1,0000 more sq. feet to that rating

    The BTU ratings and square footages for the ThermoWind water-less furnaces can be found HERE

    BE AWARE that many manufacturers will take a furnace similar in size to our smallest one, will tell you that it will heat 7 or 8 thousand feet. What they DON'T tell you, is that you will have to load it more than twice a day. I've heard from quite a few customers that were sold too small a furnace (just so the company could make a sale) and then they ended up loading it every 6-8 hours. This is not fair to you!

    Please keep in mind that this is for a house is well-insulated, according to today's standards. If you have an older or drafty house, you will have to adjust the size needed.

    There is no negative to getting a bigger furnace because it is not like purchasing an air conditioner where if you get one too big, it becomes inefficient. It is simply like getting a bigger fuel tank so that it will hold more fuel and you will need to fill it less often.

    Your wood source makes a big difference too. While hedge or orange wood HAS 32 Million BTUs per cord, Hickory has almost 28 Million, Red Oak has 24 Million BTUs while Ash and others are in the high teens - so you can see a big difference in the wood you use and load times! You will use 70% more softwood to get the sane heat as oak, however you can almost cut your load times in half using hedge (Osage). Most any hardwood has more BTUs than all species of softwoods. See our BTU list for wood 


    Find out how many BTUs you need HERE or check the label on your current furnace.

     

    The ThermoWind wood burning WATER-LESS furnaces are pre-wired and include the BIG 2100 CFM 3-speed furnace fan and a forced-air draft fan that is solenoid activated.

     

    What else will I need to buy?
    Yes, we sell anything and everything needed, for your Hyprotherm Outdoor wood burning furnace.. 

    Here is a list of the parts you need for your water-less furnace:

    1. 12 gauge power wire (usually underground rated)/

    2. Thermostat and wire to outdoor furnace.

    3. 12" round ductwork for the supply and return. You can use standard galvanized or aluminum ductwork that you snap together and insulate or you can use our insulated UNDERGROUND duct work that can be buried and hidden, just like with a water furnace!

    We are the ONLY FORCED-AIR WOOD FURNACE MANUFACTURER that has this!! CALL BEN at 828-683-8055 for pricing and to order.

    - cement for the pad (if you choose to have a pad) or you can use solid concrete pavers.



     

    Can I install the furnace in the middle of winter, so I can start saving money right away?
    You can install the forced-air wood furnace with 12" round ductwork for the supply and return. You can use standard galvanized or aluminum ductwork and install the underground ductwork if you want to later, when you can dig a trench - IF you want the insulated underground ductwork.

     

    Do I need a cement pad?
    No, but a cement pad is always best. It will stop any moisture from permeating out of the ground. If properly sized, it will give you a stable place to set the outdoor furnace or wood boiler. It will give you ample room to stand out of the mud and/or snow.

    Some of our customers use solid concrete blocks (or pavers) and even railroad ties. It is recommended that you thick plastic down before using concrete blocks/pavers or railroad ties.

     

    Is wood burning bad for the environment?
    A wood heating system is the right choice for the increasing number of consumers who are concerned about our environment. Wood is a totally renewable resource, which, when burned, results in no net carbon dioxide increase. Carbon dioxide is a part of the natural plant-growth cycle and occurs naturally when trees are allowed to rot on the forest floor. 

    Burning wood gives off no more carbon than a rotting tree!

    On the other hand, fossil fuels release carbon dioxide when burned which otherwise would stay trapped in the earth. This causes a net increase in carbon dioxide, which is believed to be responsible for the heat-trapping "greenhouse effect." So when heating with wood versus fossil fuels, you actually achieve a net reduction in greenhouse gas emissions. 

    In addition, harvesting firewood has a pruning effect on forests, which allows net growth to flourish. The wood you burn likely comes from your local area -- it's not imported and not subject to price increases due to events outside your control, as is the case with oil.

    Many times the owners have land with fallen trees spread throughout abundantly - which means FREE WOOD!

     

    How long will the furnace last?
    We have a 20-YEAR WARRANTY ON-SITE WARRANTY with an exclusive 100% PAID 5-year ON-SITE parts AND labor warranty on our outdoor wood burning furnace. Electrical components are guaranteed for one year to two years.

    The life of your furnace depends upon proper maintenance. With proper maintenance your outdoor wood-fired furnace will give you many years of dependable service.

    We have Hyprotherm Furnaces in service that are over 30 years old+, with wood siding - the way we used to make them!

    What about Stainless Steel Wood Furnaces?
    Stainless steel may not last longer than mild steel in an outdoor furnace, because all stainless is NOT a “forever” product. There are many grades and some of them are subject to rusting and corrosion. Automobile exhaust systems are made from one of the lower grades; they resist high temperatures but totally corrode in time. 

    Stainless is expensive so the fireboxes are made very thin (1/16"). Stainless gets stress cracks in it which get bigger and bigger until you have a BIG leak (in the case of water furnaces)!

    STAINLESS STEEL OUTSIDE BOILER CRACKS


    STAINLESS STEEL OUTDOOR FURNACE CRACKS

    We have replaced leaking stainless steel furnaces only 5 and 6 years old!

    Most outdoor furnace manufacturers went to stainless steel to get in on the stainless quality image, but since it’s expensive many of them went to a low-cost, cheap-grade stainless - which is still subject to rust and corrosion! During the manufacturing and welding process for stainless steel, IF the proper quantity and blend of corrosion-resistant and stabilizing elements are used, then it does indeed become a “forever” product. This is not normally done and post-weld annealing is needed to restore ductility, formability, toughness and corrosion resistance.

    If you do purchase one of the lower grade stainless steel furnaces, be sure that exact model has a proven track record of corrosion resistance. The furnace design is every bit as important as the material that it’s made from.

    Our original 30 year-old water furnaces are still in operation today - thanks in part to a STANDARD 4/10th (.380) inch firebox; as thick as .500 or 1/2" Thick Firebox.  

    1/4" is standard on Forced Air models for faster heat transfer = no cold air blowing into your home!

    However, 3/8" and 1/2" fireboxes are available. 

     

     

    How long is the warranty? 20-year Warranty
    We  have a 20-YEAR limited ON-SITE warranty. There is also a 100% PAID 5 year unconditional ON-SITE warranty including parts and labor on the entire structure. The electrical parts such as the aquastat or thermostat and fans have a one to two year manufacturer's warranty.

    We don't have you ship the furnace back, like some companies. What good is a warranty if it's going to cost you a thousand dollars for shipping?

    We also don't send you a roll of 26 gauge metal, like one owner told me, along with a list of local welders! Can you believe that's how some people (dis)honor their warranty?

    We send a man out, to your furnace and it's repaired on the spot should a firebox problem or air chamber problem surface!

     

    What can I expect to pay for an outdoor wood furnace?
    Total prices on an outside wood fired furnace will vary depending on the shipping location but our prices start at a low, low $4897 for the Thermowind 1000 and as low as $3697 for a boiler.

    We also offer financing

     

    How much do I need to pay NOW, to start my custom furnace?
    The deposit is normally a minimum of 50% on any Boiler or Forced-Air wood burning furnace..

    You can pay with credit card, debit card, cash, check by mail, check by phone and PayPal.

    The balance is before it is put on the truck for delivery.

    If shipping by freight, the balance must be paid before the furnace is picked up bu the shipping company

    (You can LOCK-IN Current AND Sale prices with a deposit of $1000).

     

    How heavy is your furnace?
    Our forced-air wood burning furnaces weigh in at a hefty 2069 lb shipped, for the 1000 which is a testimony as to how much steel is really in the furnace. The 4000 weighs in at 3600 lb.  

    The 185 Boiler is 2190 lb and the mid size top-loader is over 3 tons and the biggest (Stump Burner 6x6x6) is 6 TONS!

    By contrast, the Hardy H2 furnace only weighs 650 lb. The Hardy H4 is only 850. Hmmm...

    Won't the firebox burn out eventually?
    The Hyprotherm Outdoor Wood Burning Furnaces are made with heavy gauge 1/4" steel; FOUR TIMES THICKER than stainless steel) and will never rust out, to be sure. Can you imagine a piece of metal 3/8", ever rusting or burning though? What about our HALF INCH OPTION?

    Many stainless-steel boilers out there are only 1/16" thick because stainless-steel is so expensive!!  Picture how thin a 1/8" drill bit is and then half that size!

    We have replaced many Hardy boilers that had water gushing into the firebox, for that reason.

    There are many Hyprotherm Furnaces and Boilers over 30+ years old in service, still going strong.

     

    Why don't you use boiler plate?
    Boiler Plate has a higher tensile strength than mild or regular steel and so it is less prone to rupturing. That is needed in a pressurized unit, like actual boilers and old steam engines.

    The industry has thrown the name around (boiler plate) as if it was needed when it is absolutely not needed. It is of no use in a non-pressurized unit. 

    Our 3/8" fireboxes probably have more tensile strength than the others with their "boiler plate" fireboxes!

    Our half-inch thick fireboxes definitely do!

    Is there a safety latch or anti-blowback latch?
    Door Anti Blowback Catch -- This unique feature on all Hyprotherm outdoor wood fired furnaces assures you that we are thinking about safety first. The latch releases the door in steps, allowing for the gases to escape safely preventing possible blow back and serious injury.

    safety latch

     Note the "Stay Cool" handles

    Is there a lot of heat loss when the unit is outside and it's below 32° F?
    The units are highly insulated to avoid heat loss. In fact the snow doesn't even melt on the outside in the winter. That means that heat is being kept inside.

    With our optional Cold Weather Package you get R56.8 in the walls and an amazing R56.8 in the ceiling!

     

    Can I connect the Hyprotherm to a forced air heating system?
    Yes, more than 95% of all installations are connected to existing forced air heating systems.  

    Any system with ductwork and a fan is considered a forced-air system, including heat pumps, geothermal units, water furnaces,

    Our heating system is MUCH hotter than heat pumps and
    geothermal systems which are often only 110F at the ducts, whereas ours are as hot as 170-180F (homeowner adjustable)!
     
    Most all of our customers install the furnace themselves (95%) and this waterless model is the easiest of all, to install!

    The electrical hookup is simple 110V wiring. Just run a power wire to out junction box and make the simple connection. Connect the thermostat wires and toy are done once you hook up the duct work! 

    You MAY want to use a heating and air guy to help with the ductwork - your call.

    You can pour the concrete pad, if you're going to use one. It only takes about 1/3 to 1/2 yard of concrete.

    You can also use railroad ties and solid concrete 4" thick blocks pavers.

    Everything is very simple and easy to do. There is a 59 page manual that will help you every step of the way. You can also call me or the factory for assistance at 879-895-2688 or Ben at 828-683-8055.

     

    Can I put the forced air furnace in my basement?

    Yes, you can and quite often that is a good idea because you are very close to your ductwork usually.

    You need to keep in mind two things though.

    You need to have a chimney that goes through the roof and quite often that is impossible unless you have an existing chimney (but very often they go into the basement too, for support).

    It can also go through a basement wall and turn up to exhaust the gases but it has to go up quite a ways (normally above the roof line) according o most building codes. If it outside, that is not an issue,

    PLEASE CALL FOR FURTHER INSTRUCTIONS!

    You have the same issue when in a basement as a shop or outbuilding because you when open the door(s), smoke will escape. You need to have a good ventilation system to exhaust any smoke or it will go up through the home.
    Can I connect the forced air furnace to my ductwork in my attic?
    Yes, you can, but it can be quite difficult because the ductwork involves two round ducts that normally have to get up from ground level, up to an attic.

    We have had folks to run ductwork on an outside wall, through a chase that was insulated.

    Again, because of the size, that can be a tough thing to do and will likely not look right.

    This is easier done with a boiler, because now you are dealing with two one inch pipes, instead of 12 inch pipes (ducts).

    It is pretty easy to get the smaller one inch pipes up through a closet or spare room, into the attic!
    Will my existing furnace take over as a backup?
    Lets just imagine that there is a big snow storm and you can't get home to put wood in the fire. Eventually, the fire will die down  and you will no longer have any heat coming into the house.

    The thermostat for your existing furnace would sense the drop in temperature and automatically turn your existing indoor furnace on (without relays, switches or circuit boards).

    Once you feed the outdoor furnace and restore the fire, it would again take over from your existing furnace.

     

    How do I keep my furnace going in the event of a power failure?

    A small generator will do the trick. Use a 4000 watt generator for the ThermoWind models and you will have plenty of extra juice for lights and small appliances.

    Use a smaller 700 Watt generator for a boiler model.

    Most of the power needed is for starting the furnace fan on our outdoor wood fired furnace.

    This is how you become self-sufficient with your outdoor wood burning furnace.
     

     Have heat when no one else does!

     

    I only have baseboard electric heat, how can I use the Hyprotherm? What about NO heat?
    Without a furnace or ductwork, you can  use a Thermowind (water-less) Model and run two ducts (a supply and return to two rooms in your home (one to each), preferably at opposite ends of the house for better air circulation and more even heating) or you can install ductwork in your basement or crawlspace, with smaller distribution ducts (6") to better distribute the heat to each room as needed.

    Only with a boiler can you replace electric baseboard units with Hydronic baseboard heaters.

    With a boiler, in an open area like a shop or garage, you can use hanging heat exchangers, with a fan on them.


     

    Can I heat my domestic water with the Hyprotherm water-less furnace?

    Normally, you will need to purchase a water furnace to do that.

    However we have a new option for $489, whereby a forced hot air furnace can heat your hot water!
     
    Can the Hyprotherm heat my pool and/or spa?

    No, you will need to purchase a water furnace to do that.
     
    Can I heat more than one building?

    Yes, you can purchase a ThermowWind 4000 with 2 sets of ducts; 2 supply and 2 return BUT there is only 1 thermostat hook-up, so you have to control the air supply to the additional building mechanically, with a damper OR we can add another controller

    Otherwise, you will need to purchase a water furnace to do that.
     
    I have two heat pumps or furnaces. Would I need two outdoor furnaces?
    NO, that is easily done with the ThermowWind 4000 because it has FOUR ducts, @ supply and 2 return - or a boiler because you can put as many as 4 heat exchangers in series, with 2 water lines. 
     
    Can I use an outdoor wood furnace if I live in town?
    Outdoor Wood furnaces may not be the best fuel choice in densely populated urban areas where neighbors could be annoyed  complain. Smoke can also overwhelm your neighbors if the wind blows the wrong way. Remember, automobile exhaust and other pollution already puts excessive strains on air quality. 

    However, in suburban, small town, and rural areas, wood makes good sense. If you choose to install your Hyprotherm furnace in a densely populated area the stack height should exceed the rooflines of existing homes within 200 feet. Some states have their own laws and ordinances.

     

    How often do I have to fill it up?
    Many of our customers put wood in their furnace at 8 AM and 8 PM (or other times 12 hours apart) in the dead of winter, with plenty of wood still left over. 

    So 2 times a day max normally, using a good dry hardwood like oak. Some people do it just once a day, depending on the size of their home, how cold it is outside and the type of wood they are burning. i.e Oak had 24,000,000 BTU per full cord, while Pine only has 14,000,000 BTU per cord and Hickory, Locust or Hedge has over 30,000,000 BTU per cord!

    Or you can do as I did and buy a bigger furnace, so that I only fill mine ONCE a day, which is real nice is the freezing cold, freezing rain, windy or even the blistering COLD!

    There is no negative to getting a bigger furnace because it is not like purchasing an air conditioner where if you get one too big, it becomes inefficient. It is simply like getting a bigger fuel tank so that it will hold more fuel and you will need to fill it less often.

    Does the furnace come fully assembled?
    Yes. Like most major appliances the unit is delivered to you ready to install.

    Just like a dishwasher; all you have to add is power and ducts or water lines with a boiler!

     

    Does your furnace burn continuously or does it shut off and on according to if the furnace is operating or some other method?
    All forced-air furnaces cycle off and on (even the one in your home) as demanded by the indoor air temperature (and thermostat) - so the fire is NOT burning all the time.

    The big 2000+CFM blower only comes on when the indoor air temperature drops and well exceeds that of a heat pump or whatever you set it at. 

     

    Can I extend the chimney of flue pipe?

    YES, you can add standard 6" flue pipe using our flue adapter. Double wall pipe is ALWAYS recommended when going extending the chimney as it will greatly reduce creosote buildup!

    We have folks with 20 and 30 foot chimneys and they all draft well because of the 75 CFM forced-air induction fan.

    Do these furnaces need to be near the house?
    UL says that our furnace and boiler should not be within 5 feet of flammables. 

    Some people have the right outside the door, as these people do (photo above) so they can run out and throw some wood in fast.

    I have my boiler 60 feet away, which is nice.

    Normally a boiler is no more than 250-275 feet away because that is the longest piece of un-spliced Pex pipe that you can buy and most people don't want to walk that far in the snow anyways!

    We recommend that the Hyprotherm Outdoor Forced-Air (water-less) Furnace be within 40 feet of your home. Longer distance are possible but will diminish air flow and heat output due to turbulence and heat losses.


     

    Is there an elevation concern for the placement of the furnace?  

    No concern with a forced-air furnace.

     

    Do you offer financing?

    YES!
    Our simplest option is an in-house layaway program and there is no interest!

    However, as with any layaway, it must be totally paid for before it is shipped.

    WHY OUR FURNACE IS THE ABSOLUTE BEST!
    SIMPLE! We make our furnace simple, so anyone can work on it.

    First and foremost the firebox thickness is the most important factor. We have a standard 3/8" thick firebox on our boilers and 1/4" on our hot air furnaces - the same as boilers from our nearest competitor. 

    WE have an optional 3/8" thick firebox and a super thick 1/2 inch Thick firebox option; FOUR TIMES thicker than most!

    We have a 20 year parts AND labor warranty. Most others just cover parts or their warranty is much shorter - read the fine print!! (Fans and electrical parts have a 1, 2 or 3-year warranty.

    There is a forced-air induction blower in back that feeds air into the firebox, below the grate, to feed oxygen into the bottom of the fire. Feeding the fire from the bottom (just like a blacksmith's forge) is the best way to get complete combustion from the wood. 

    This is infinitely better than a fan on the front door blowing air into the front of the fire - or a manual draft. Our fan has a simple solenoid activated damper so that you don't use any extra wood unnecessarily!

    The grate is made out of 3/4 inch steel bar stock OR you can get an optional Cast Iron at $65 per grate). We have NEVER had one burn through! Most furnaces don't even have grates; forcing you to kill the fire, open the firebox door (letting out all of your precious heat), clean out the ashes and then restart a fire in the dead of winter!

    The Legacy (original) firebox is round and is 36" wide x 26" high (due to the grate and ash pan in the bottom) x 34" deep. It is made from almost 4/10th of an inch of solid steel. We've never had one rust through! Square fireboxes take 12 or more welds to put it together. Every weld is a potential leak. A round firebox only takes two continuous weld on each end for the end plates! A tube is MUCH stronger than flab slabs of steel that can bend and warp.

    It is totally surrounded by the water jacket or air chamber; top, bottom, front, back and both sides, so that it absorbs the maximum amount of heat possible!

    Our new model (starting in Fall 2017) has a firebox that is formed with a 430-ton press brake, instead of welding flat slabs of steel together, with so many welds and their inherent leaks.

    It is surrounded by the water jacket or air chamber; top, front, back and both sides, so that it absorbs the maximum amount of heat possible!

    Almost as few welds as on a cylinder; Only 4 welds vs. 12 welds on a typical firebox. Three times less!

    Not only is the firebox thicker; the water jacket bottom is THE SAME THICKNESS as the firebox because it is the most vulnerable part); 3/8" standard and the 1/2" THICK firebox option gives you a HALF INCH THICK water jacket bottom as well! NO ONE ELSE DOES THAT!! 

    The chimney is made out of 5 inch schedule 40 pipe (1/4" thick) and heats up the air in the chamber as well. It tops out at about 90" above ground. You can EASILY add extensions with standard 6" stovepipe. See photos above) Smaller diameter flus mean much less heat loss.

    The chimney is low in the firebox and exits about 1 foot from the bottom shelf, so that the smoke - or more importantly, the heat - is trapped so that it doesn't quickly escape out the flue. That would be a big loss of efficiency. This is also a better idea since you don't have baffles creating a lot of smoke and getting a creosote buildup on them that's hard to clean.

    This also creates a huge secondary burn chamber, to more completely burn the gases and wood! When wood starts to burn it's the escaping gas that burns first, then the wood!

    The water surrounds the ash one as well. As anyone with a woodstove or furnace knows, ashes put out a lot of heat!

    There is a full-size rear door approx 40 x 48 inches. This makes it VERY easy to make connections and to service it. There is no need to pull the whole shell off as with other furnaces!

    We have an extra large, waist-high loading door 26.5" x 26.5" with a 24" x 24" inside (loading) dimensions, suitable for putting really BIG pieces of wood in! 

    Remember, a 30" log, 15" in diameter weighs 115 lb! 

    The door material is 165 lb with motor mount style hinges and the best K-Factor insulation.

    These furnaces now come with a double flood light on the front for safety and ease of loading the wood. Not only that, it's a MOTION LIGHT! No switches. No forgetting to turn it off. If it's dark outside and you go near the furnace, it turns on!

    There are legs on the bottom with a skirt surrounding the bottom to ground level to keep it warm and dry.

    The exterior is made of Heavy Duty Siding - 29 gauge with 10 coatings and it has a Lifetime film integrity warranty and 30 years against fade and chalk

    We can build just about anything. Billy did one recently that was 8 feet long and another that had a 10 feet long firebox, with sizes up to 14 feet!!!

    Can I get the furnace without siding for use in an outbuilding or if I want to put on my own siding?
    Yes, you can get the furnace without siding for $300 less. It is normally shipped without insulation.

    You can also add other types of siding or concrete board and lathe to the frame in order to add brick, stone, etc.

     

    Do I have a choice of colors?
    The Hyprotherm Furnace is available in TWENTY-ONE different colors, (17 are free) to be sure it will compliment the exterior of your home or match other buildings.. Currently available colors are shown below:
