Outdoor wood BOILERS are now OUTLAWED in ALL 50 STATES! BUT this is NOT a BOILER!! Because the law only prohibits wood ” BOILERS ” in most states! FYI, People simply hate how hard the EPA models are to start and that it’s a full-time job to keep them running because with them, the wood has to be dried, under cover, for a minimum of two years! NOT THE CASE WITH THESE WATER-LESS FURNACES! These new EPA models have a refractory (much like a jet engine) that must use special fuel remember unleaded gas? Wood MUST have LESS than 20% moisture content; must be dried under cover for a minimum of TWO YEARS Who does that? Just like the cars of the 60s that had lots of power and got great gas mileage, used regular, less expensive gas, had gobs of power and could smoke the tires; then the EPA got involved and cars suddenly had 1/2 the horsepower and only got about about half the gas mileage and became dogs with catalytic converters!

This furnace can go outside and does not have to be bolted or be so very near to the house or go in the basement like every other model out there! Heat is carried to your home through galvanized 12″ ducts OR insulated 12″ ducts, which CAN be buried underground. No more worries about frozen water. NO CHEMICALS or annual water tests! Perfect for folks who have power failures often or those people with cabins or homes that are left unattended. NOW there is no need to put the furnace right next to the house or in the basement!

Reply by aware: We’re glad you like our Outdoor Wood Burning Furnace! As nice, courteous, and helpful a sellers as you will EVER find! Would recommend excellent service thanks guys. Wood Boiler seems like a great unit. Yet to hook it up. We make it simple without a lot of expensive electronics to break. We make it user serviceable. Anyone can maintain our furnace! We give accurate BTU ratings using an established scientific formula. They say what sounds good. We have a 2-light motion detector light on the front (not installed for its protection). We have a forced-air fan; not a dismal damper to fuel the fire with oxygen. Our 75 CFM inducer fan is in the back , at the bottom, where you can’t get shocked AND it blows the air through the grate into the bottom of the fire LIKE A BLACKSMITH’S FORGE – NOT into the side of the fire! Fires burn from the bottom up, right? We have been building fine energy efficient furnaces for 48 years! Our standard grates use super THICK 3/4 Bar Stock! This Model: HyProTherm ThermoWind 4 000 is Rated to Heat up to 10,700 sq. As a test of burn times, the owner of HyProTherm Furnace took the thermostat off his 25 year-old water furnace, so that the fire would rage at maximum burn 24 hours a day. Yet he still only has to load it every 12 hours, at maximum burn – never shutting off! Normally, he goes as long as 24 hours without reloading it. I get a wh o le day with m i ne! A n other customer called and told me he goes 18 hours between loads (1/17/08) I, personally, get 24 hour burn times; loading it just ONCE A DAY! Don’t believe the hype and misinformation about 43-98 hour burn times. This is only true in the summer. Forced-Air furnaces tend to get 20% longer burn times. Smaller model shown; ready to hook up to the OPTIONAL insulated underground ducts. NO risk of water freezing! No chimney fire risk either! No logs to carry in means no messy ashes and bugs in the house! The chance of carbon monoxide build-up in your home is eliminated. Eliminate allergies by getting the smoke outside! The chance of a gas explosion from your furnace in your home is eliminated. Indoor pollutants of harmful gases and fumes are eliminated too. Eliminates the chance of chimney and flu fires from your furnace. If you live in a suburban or rural area near a source of cheap wood, you could heat your home for the entire season for the cost of one month’s electric heat bill. An outdoor furnace requires less tending. No inside oxygen is used to fuel the heat like other wood or gas burning units. Does not cause respiratory problems like burning wood indoors. Instead of 12-18′ wood split, you can put 30 pieces in this one and full rounds. Burning wood, a total renewable resource, is less expensive than other fuels. The cost of electric, gas, oil, or propane can be very erratic. The low cost of wood remains constant – or FREE! The furnace hooks up to any existing gas pack, heat pump or forced air system; even buildings with no ductwork or existing heating system ca use it. Most people pay for their furnace in 1 year or less! Where else can you get that? An outdoor wood burning furnace is the BEST INVESTMENT! A n older water furnace is shown here for color. Get the Bugs, Dirt, Wood and Smoke outside. Your lungs will love you! Many people are getting lower rates because they are getting the fire and related hazard, out of the house! Extra large, 2 foot by 2 foot, waist high loading door. No more bending over, straining your back to load wood! Lever action safety latch! A PROVEN design – since 1972! We feel we build the safest furnace (nothing electrical outside). We have the BEST PRICES and a Very Friendly Staff to help you every step of the way. These furnaces now come with a double flood light on the front, for ease and safety of loading the wood at night. Not only that, it’s a MOTION LIGHT! No forgetting to turn it off. If it’s dark outside and you go near the furnace, it turns on! New, nicer looking furnace – NO SILICONE Now with nice neat looking butyl tape and grommets. These TWO DOORS doors ARE HUGE! Remember, a smaller 15″ round log, 30″ long, will weigh 112 lb – more than most people can ever lift! Trust me, the door is more than big enough for anything you can lift into the furnace AND the thick door frame will take a pounding as you throw them in! 2 4 ” x 2 4 ” – The TOUGHEST door you’ll ever find with TWO 1/4″ solid steel plates separated by a 3″ air shield; filled with the BEST EVER Ceramic Wool Insulation insulation. This inner plate keeps the hot air in and deflects it off the door. With very little metal to transfer heat to the door it does an excellent job of insulating the door. There is also fiberglass insulation BETWEEN the plates now! Very heavy duty hinges! OURS won’t fall off! The chimney is low on the firebox and exits about 1 foot from the bottom, so that the smoke – or more importantly, the gas and heat – is trapped so that it doesn’t quickly escape out the flue. That would be a big loss of efficiency. This way the air has to cool off to find its way down and out the chimney. This is also a better idea since you don’t have hard-to-clean baffles getting a creosote buildup on them. Having the chimney come down low and stops the heat, gases and smoke from rushing right out the chimney AND creates a HUGE Secondary burn chamber to burn off all the gases from the wood – a HUGE source of energy! When wood starts to burn it’s the gas that burns first! Another advantage is that the chimney exits through the air chamber, further heating it up – for free! These are some of the reasons that our water furnace is one of the most efficient on the market. This also means that you will burn less wood than with others and therefore you will use more wood with the other – being less than 75% efficient. That’s proof, not just rhetoric. 125 and another at. Our standard THERMOWIND firebox is 1/4 to produce heat for you FASTER! 3/8 and 1/2 Firebox options. NO ONE ELSE DOES THAT! We have never had a firebox failure, crack, split, rust-through or leak in 48 years of building furnaces. We have a TWO pull-out ash pans! Some other makes don’t even have an ash pan!! That makes it HARD to clean out! You have to let the fire die down or move the burning wood aside to scoop out hot ashes. It WILL NEVER RUST through in a lifetime NO water = NO RUST! Will not get stress cracks like Stainless Steel! We have furnaces OVER 30 years old and more, still in use today! The removable, replaceable grates are made out of THICK 3/4 inch bar stock. Now THAT IS VERY thick! We have NEVER had one burn through! (Most other grates are a thin 3/8 – 1/2). Now available with optional CAST IRON GRATES. A sh pan and door. And you can see the air inducer blower inlet tube (seen in back of this picture). The blower in the back is a great aid in getting a fire started. It also recovers the air temperature much quicker, and burns the wood up more completely because oxygen is being fed to the bottom of the flame – like blacksmith feeds his fire! A clean-burning fire is more efficient than a smoky air-restricted fire. The forced draft will burn hotter and therefore cleaner. Secondary gases burn at 1200 degrees and with our furnace, they are trapped in the firebox so that they are available to be burnt off without escaping out the chimney. The HyProTherm will exceed that temperature in the firebox. The thermostatically controlled, forced air induction blower determines how hot the fire burns and therefore how hot the air in the furnace gets. A thermostat on the back of the furnace tells the blower when to turn on and off (and has a solenoid activated door) , so it doesn’t run all the time and waste wood. This is a LOT more efficient than a manual damper will ever be! The air blows into the bottom of the fire, through the grate – like a blacksmith’s forge. That’s better than blowing in from the front – into the side of the fire, as all others do (if they even have a fan). You get more complete burning from a fire where the oxygen is fed through the bottom as opposed to blowing over the fire from the side, like others that have that big box on the door! Actual photo of a fire inside our firebox, only minutes after reloading with wood! This firebox size is 36″ wide by a whopping 56″ deep; 1/3 BIGGER than the previous model (TWICE as big as the TW1000) All sizes O. The air chamber totally surrounds the firebox, top, bottom, sides, front and back. The chimney is also surrounded by air. The ash receptacle (and hot coals) are surrounded with air too! Full-sized forced air fan for your home or building and a forced air fan for furnace induction, with solenoid activated damper to shut off air supply when the fan turns off; saving you wood! Simple fan(s) temperature controller shown here (Furnace is BLACK ALL OVER). TWO bigger, quieter, smoother 2010+ CFM blower 33% bigger than in most homes! Installed standard – on left above. The fan will not turn on until the air temperature is 125F or higher, so that you don’t have cold air blowing into the house. You get a solenoid activated inducer blower with damper too! All parts are available everywhere. OPTIONAL INSULATION SHOWN Most common method: The Army Corps of Engineers built a chase around the ductwork and filled It with standard fiberglass insulation to keep the ducts warm and dry. They used the same material as was on the side of their building to give it a uniform appearance and you can do the same. NOW there is no need to put the furnace right next to the house or have unsightly ductwork going across the yard! The two connectors in the back hook up to the INSULATED blue pipes which are buried in the ground, either with standard 12 inch galvanized ductwork, that you would insulate yourself or you can use the black pipe shown at the top of this ad. This is the same as the blue duct work and is specially designed and made for our furnaces. These pipes are only 12″ in diameter so a standard backhoe with a 24″ bucket can easily dig a trench for the pipes to lay side-by-side. Ideal for new construction under a slab or basement, as you can see here but you would just need two pipes running to the house in an existing structure to connect to your ductwork. Our new firebox is made utilizing a 430-ton press brake to form one piece of metal into the shape of the firebox. We also do the same with the air jacket. It also has two end-plates that are welded and we weld it to the floor, which is also the water jacket bottom and is the SAME thickness as the firebox. No one else in the world does this! Instead of 12 welds to weld 6 flat slabs of steel together, we have just 4; two-thirds less! Our new removable ash pan is easily cleaned at the front! Some other makers don’t even have an ash pan! You have to let the fire die out or shove the hot burning logs aside – then clean it out while the firebox is 800 to 2000F degrees – and then restart the fire in the dead of winter! Who wants to do that? Air surrounds the front and back of the firebox and the ash pan as well. Heat from the red hot coals. The much smaller TW1000 is shown to the right >>. There is an air handler/blower that feeds air into the firebox, below the grate, to feed oxygen to the fire. It is thermostatically controlled and solenoid activated for greater efficiency, to keep the air temperature in the furnace between certain parameters. This is far better than an inefficient manual or natural draft opening. Black door on Blac k steel. Our furnace is so strong and well-made, that the chimney alone is strong enough to carry even the 3680 lb. Weight of our biggest water furnace! We move them like this every day! Exterior is made of Heavy Duty Siding – 29 gauge structural quality, full-hard steel. 10 layers of protective coating. 1 7 c o l o r s to best suit your surroundings! Mix and match the roof, roof trim, sides and corners and even the front can be a different / darker color so it doesn’t show the smoke stains as much! There are legs on the bottom, that you can’t see, with the siding surrounding the bottom to ground level. Concrete pad is recommended but not necessary. Use railroad ties, solid concrete blocks or? The chimney is made out of 1/4 thick, solid steel pipe and is surrounded by the air chamber, to extract more heat. It tops out at about 90 feet above ground. You can EASILY add standard 6 stove pipe extension(s) with our FREE adapter (ask for it when ordering). Some other manufacturers have to have the whole hull removed by 2-3 people! Extra Large rear access hinged door. All electrical items are in back, safely behind the door/lid! Easy pipe (air) and electrical hookups (simple 110V wiring). No special tools needed. The easiest furnace for the self-installer to put in! 95% of our customers install our furnaces themselves! We help you every step of the way! Many people can pay for their furnace in a year and a half OR LESS of oil or propane bills! Start with a small piece of wood. Seriously, you can use these bigger, cheaper pieces or smaller ones – whatever you can easily handle. ANY wood is cheaper than oil, gas and electricity! One person said that they have never used their propane heater after propane prices tripled! Whole rounds burn longer and cleaner and it’s SO NICE not having to split the wood! Shove the logs in on top of each other. Use the big, thick poker (provided) for safety to push them in. That big THICK 5/8 poker comes with the furnace – for FREE! Thought there wasn’t a fire? It can look as dark as night in the firebox, but within a couple of minutes – literally – this fire was roaring! This is our original style of firebox which we loved because there were no welds to make the firebox except for two to weld the end-plates on. Our new firebox is much the same because utilize a 430-ton press brake to form one piece of metal into the shape of the firebox. It also has two end-plates that are welded and we weld it to the floor, which is also the water jacket bottom and is the same thickness as the firebox. Instead of 12 welds to weld 6 flat slabs of steel together; we have just 4 welds; two-thirds less! K-Factor 1800F Ceramic Insulation. NOW FREE with THIS AD! COMBINED with Ceramic Superwool on the front (white – at the firebox) where temperatures can be 800F and Knauf insulation blanket (brown) on the side, insulating the air jacket, which is below 200F – for superior performance all around!

As a test of burn times, the owner of HyProTherm Furnace took the thermostat off his 25 year-old furnace, so that the fire would rage at maximum burn 24 hours a day. Yet at MAX burn, he still only has to load it every 12 hours. A customer called and told me he goes 18 hours between loads (1/17/08) Others have reported 24 hour burn times! I GET 24 hours out of mine! We will always size the furnace for you to achieve once a day loading (24 hour burn), if you want it! There is no negative to getting a bigger furnace, like this one 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. Don’t believe the hype and misinformation about 42-98 hour burn times.

Questions about stainless steel answered. Do you build with stainless steel? No, we don’t build stainless for several really good reasons. Our furnaces last longer than stainless with MANY of our water furnaces still in use after 30 years plus!! Mild steel transfers heat better than stainless does. Stainless is a great sales feature, but little else, since most companies use cheap stainless, like a car’s exhaust system. There are many grades of stainless out there. Since stainless is so expensive, the fireboxes are made really thin. Some are no thicker than the metal in a 55 gallon barrel or the thickness of a trailer fender!! That’s why you see so many split and broken apart. Our optional firebox on water-less furnaces, is 1/4 thick – normally found on traditional boilers, giving faster heat transfer! Our optional firebox on boilers, is almost. 500 inches thick (HALF INCH) as opposed to as thin as. 125 in many furnaces. Stainless is more prone to stress cracks, so why use it? Unless the stainless is retreated after welding, you’ve lost all of it’s great properties through the heating of the metal. And it’s being welded to mild steel anyway, so what’s the use? Like I said, it’s a great sales feature but our super thick mild steel furnace heats better, doesn’t crack and split – and last longer! If stainless was better, we’d surely be using it after 47 years of experience. The potential for electrical shock is something we have tried to totally eliminate. That is why unlike our competitor’s stoves, our stoves do not have electrical control boxes, draft fans, etc. We believe these impose too much risk should a problem ever arise. We also believe that to have anything too complicated on a wood furnace is unnecessary. We have made our furnaces to be simple, and reliable and we have proven that with 47 years of use. We do not have complicated self-fill, bladders or water level indicators on our furnaces. You don’t need them with Forced-Air! These stoves were developed by us, for our own use. We started making them for others slowly and now our stoves are well known locally for their simplicity, and their maintenance-free operation. Forced-Air Wood Furnaces are indeed an excellent, almost zero-maintenance heating choice. HyProTherm Furnace is a privately held company and was established in 1972. Heating and Air company preceded it and dates back to. Billy (the son) and his Dad (Gerald) were in the heating and air business for decades. They began to develop their first prototype. For their own home. In the 60’s. Gerald Shaver knew there had to be a better way than to pay for oil, even though it was cheap back then. His main concern however, was to get rid of the smoke and ashes in the house. It was obvious it could cause serious health problems. Besides the soot all over the place was a chore to clean. Having the wood outside already, made the plan simple. Put the wood stove outside! He developed a model for himself and continued to improve on it over the years. Our furnace was indeed the first. The last revision was made in 2009 and the furnace remains unchanged, except for cosmetics, today. Now Gerald’s son, Billy heads up the business. Billy and Ray developed this. NEW Forced-Air Wood Furnace. We have been in business for 48 years and we are a family run business. We are a brick and mortar business in Salem Arkansas – and we are here to stay. We stand behind the quality of our furnaces 100%. We believe that we can give you a quality furnace and save you hundreds if not thousands of dollars at the same time.
