BETTER than Scratch and Dent!! (Because these don’t have dents or scratches, just low , low prices). In over 4 years we have never had a sale as good as this! The last time we had any was 4 years ago and we have limited supplies of these USED furnaces, just the way we have made them until a couple of months ago. All furnaces have been completely factory refurbished! ALL refurbished LOOK LIKE NEW and all furnaces have 100% new tin and insulation! New grates, new door seals; on firebox and ash receptacle doors! Built-in domestic hot water heat exchanger! All have a thermostat and chimney cap! All have TWO sets of ports to heat an additional building. Pumps supplied at cost according to your needs/distance/elevation change. 75 CFM forced-air induction air blower included, and auto damper, which saves a lot of wood! Please allow 2 weeks for completion because we completely refurbish each furnace for you, the customer; custom rebuilt with your choice of available colors. All furnaces have been updated with the new hot water coil cover which puts the water level at the very top of the water jacket! No separate domestic Hot Water plate or side-arm heat exchanger is needed Nor is a tempering or mixing valve needed, to avoid scalding water!! You also get a thermostat to control the water temperature in the furnace, automatically – along with a 75 CFM induction blower fan, in the back, to feed air to the bottom of the fire, like a blacksmith’s forge. The automatic damper is a simple solenoid activated damper; that opens and closes the door on the side of the fan, so instead of it being a manual adjustment, it will open and close that door 100%, which will stop the air from drafting into the firebox when the fan turns off. According to our customers, this saves a tremendous amount of wood and gives you better temperature control in the furnace. There aren’t any circuit boards to fail or fancy electronics to give any problem! No proprietary parts; you DON’T have to come to us to get any replacement part. Our boilers are so strong that we can hang and move them from the chimney because it is 1/4″ thick steel welded into our super strong ROUND 3/8″ THICK firebox. The chimney drops down into the firebox trapping the heat in the firebox to heat the water and not the outside air – but more importantly, it traps the gases from the wood in the huge secondary burn chamber that we created in the top of the firebox. As soon as there is a flame, all of the gases bet burnt, extracting that much more energy from your wood that would otherwise be wasted! We custom refurbish every furnace for you , so when you order, you can specify. Choice of 20 great. C o l o r s , while in stock; limited availability. Roof, sides, corners and roof trim and even the front can be a different color with over. We have been in business for 44 years, in the same factory location 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 thousands of dollars on these refurbished furnaces, at the same time.

A WORK IN PROGRESS. More photos just added! See photo of man at furnace, for a more realistic idea of its actual size and how easily it can be loaded! Look at Our Newly Designed Fireboxes When we decided to reinvent the wheel we knew that we had to start at the beginning and to us that meant the firebox. That is why at the heart of every HyProTherm furnace is a firebox unlike any other in the industry. Based on the knowledge that fire naturally rises and as it does it creates currents of air, we designed our HyProTherm fireboxes to maximize this potential. By utilizing the upwards drafting, funnel shape of a tornado, we have created a furnace that will burn coal or wood with almost no assistance from a combustion blower. Not only that, but our design will burn green sawdust, shavings, pellets, corn, or virtually any biomass that you choose, and due to its shape it will burn more evenly, completely, and with less stirring of coals. It is also the only firebox that allows for the use of the entire firebox. Because there is no flue pipe in the way and by utilizing our top loading feed door our fireboxes hold more than a comparably sized horizontal firebox (as shown below). Standard Furnace (horizontal fire box). 13.00 CF (useable). 16.15 CF (total, non useable). 15.31 CF (total, non useable). Standard HyProTherm (VERTICAL FIREBOX). 12.48 CF (useable). 12.48 (total useable). 125 gallon water cap. North American Insulation Manufacturers Association. To Hyprotherm Manufacturing: Points of interest 1-4. In reviewing your request on your Forced Air Models and your commercial Hydronic models. We know you feel a need for a desired product. There are a number of materials that would work for your commercial hydronic and forced air stove. The high temperature fiberglass you cite below is one; there are also fiberglass and rock wool (which has a higher melting temperature) and the ceramic fiber materials (very high temp). In our opinion you will need. For the project youre looking at I think max operating temperature and corrosion resistance would be important as well as workability. Blanket materials are more flexible than boards and blocks. There are products you should not use for a thermal cycling unit. Do not use a standard fiberglass insulation meaning the standard fiberglass your using is just metal building insulation with an R factor on it tested at 75 degrees, exceeding that perimeter heat factor the R factor drops dramatically. Results to following proper recommendations. Based on our knowledge and the understanding of your needs, by using our recommendations and HVAC normal codes per efficiency, you should get the results you desire.
