Our simplest furnace and the easiest to install; No underground Pex pipe,
No heat exchangers,
No proprietary parts, No water, No rust, No chemicals or water test needed ever.
Warmer than a heat pump by at least 60 F !
Saves you hundreds in fuel or electric costs every month!
The perfect heater for a 20 foot shipping container KILN and less expensive to install than a boiler.
Will also heat a home or shop, up to 8600 sq. ft; well insulated.
Just $7997 and 50% larger than the FLFA-1000 but only $1300 more and will heat one building as warm as you want using our large 2010 CFM blower. The average household furnace fan is 1500 CFM so we are 33% larger for more air volume and heat. Our closest competitor has the smaller 1500 CFM fan and only 10" duct-work. Our ducts are 20% larger than our competition (12") for more air flow. Hyprotherm hot air furnaces weigh about double as the competition because their weight is only 780-950 lb. due to the 1/3 thinner firebox!
Kiln Heater?
This firebox is 42" deep, so you can put slightly over 3 foot logs in it and they do not have to be split! In fact, whole logs burn better and longer due to our 75 CFM forced air induction fan in the back, feeding oxygen in from the bottom, up through the grates just like a blacksmith's forge.
This size will handle a 10 foot container; 8 feet wide. You can divide a standard 20 foot container up to make that size work but most people go to the next larger model, the FLFA-3000 which is only $900 more at $8897 (33 cu, ft, firebox) and will handle a kiln made out of a 20 foot shipping container.

Thermowind Model FLFA-2000
NOT permitted in Washington state.
This is NOT a boiler and most laws speak about Outdoor Wood Boilers. So that MIGHT be your loophole.
Please check with YOUR state, county and town before buying because some states, counties and towns have their own state EPA or other laws!
Tell them that you want to install an outdoor hot air, waterless wood furnace.
If that is a no-go, ask about a COAL furnace, which is virtually the same and will burn wood even better because it has the 75 CFM forced-air induction blower feeding oxygen from the back, up through the grates, just like a Blacksmith's forge; giving you a super hot fire that will burn anything!
That means NO RUST EVER,
NO CHEMICALS,
NO WATER TESTS!
This furnace has two fans; a 75 CFM forced-air induction blower to feed oxygen in from from the bottom though the grate (which most do not have), One 12" supply duct and one return duct, for better air circulation.

Hyprotherm has an on-site warranty, unlike 85% of the manufacturers. Wherever you live, be it the US, Canada, UK or Europe, we will send someone to your location to repair your furnace if anything major* happens,
SIMPLE TOO! The only things needed are a thermostat wire, a 110V power wire and inexpensive snap-together 12" round galvanized ductwork.
We recommend a 4" thick concrete pad to carry the weight of these furnaces because this model weighs 1920 pounds.
You will need a substantial pad so that the boiler does not sink into the ground.
You can also use solid 4" concrete blocks or even pavers. Many people use railroad ties for support. The choice is yours.
This photo is to show how the ductwork comes off the back of this furnace. This example is with the insulated underground ductwork which makes it look like a regular outside water boiler.
This photo shows how many people run their insulated ductwork through a basement window, which happens to be the exact size needed, in many instances and makes installation a breeze!
This customer did a great job, connecting his 12" insulated ductwork to the Hyprotherm Hot Air wood furnace - with a substantial shelter above it, with matching steel!
2: 430-ton Press Brake
We are the only manufacturer that uses a press brake to form a firebox and air jacket; both from 1 piece of metal.
Most everyone else uses 6 flat slabs of steel, with no inherent strength and that requires 12 welds because welds are the weak spots.
This new firebox and air jacket are formed using a 430-ton Press Brake,
1 inch solid steel Grates
3: One inch thick sold steel coal grates do well. Solid Steel grates are much stronger; resistant to bowing and deformation like you may get with other thinner grates. Shaker grates made from cast iron and are available as an option, mostly for those folks burning a lot of coal, where the coal is inclined to have clinkers.
Cast Iron Shaker grates are available as an option, mostly for those folks burning a lot of coal, where the coal is inclined to have clinkers.
Our smallest models have one grate, the next two sizes up have two grates and our largest models typically have three grates.

6: Pull-out Ash Tray
Most manufacturers make you open up the firebox door to clean out the ashes with a shovel. You will quickly find out that you are not going to get anywhere near the firebox because it will be 800 F or more!
They want you to open the firebox door and you will need to leave it open to let the heat out and I call that wasting heat. You will need to kill the fire to be able to shovel out the ashes and then you have to start a fire again, in the dead of winter.
With our furnaces you do it the easy way. Even with a fire raging, you can pull out the ash tray, dump the ashes into a fire proof container and slide the tray back in without missing a lick. Two handles on the ash tray make it easy. Every ash tray is the same length as the firebox.
Hypro Therm Insulation Information
Wood and Coal Boiler/Furnace Insulation
We now have the proper insulation that the furnace REALLY needs; (we and everyone else has been doing it wrong according to the insulation engineers!)
We now have insulation with the equivalent of R-23 in the sides and R-57 in the roof and in the front against the 700 degree firebox with up to R-88 equivalent in the optional EXTREME Cold Weather Package for just $307 on any front-loading model (boiler or water-less hot air)! Available on top loaders for just $443.
The brown insulation you see is the Knauf insulation that is rated for 1000 F without failing. It is perfect for the air jacket because it only reaches 170 F; at those temperatures normal R factor (home type) insulation fails.
The white product on the front is called Superwool from Morgan Thermodynamics and is rated at 1800 F, without failing, which is excellent when insulating a firebox which can easily be 800 F to 1200 F; again where normal residential insulation will always fail!
See how great Superwool is on the video at:
https://www.youtube.com/watch?v=m9gjcnc6IAw
and
In this photo, you see the SolarGuard insulation on top of the Knauf, giving it an extra R-10 value plus it combats the three types of heat loss. This is significant seeing that this product is only 1/4" thick.
See the great video demonstration at:
https://www.youtube.com/watch?v=8D3S9CpOzcc
FYI: If you are heating HALF as many square feet as our rating, you can load it just ONCE a DAY!
REMEMBER! There is no such thing as a furnace that is too big because it is NOT like an air conditioner,
where if you get one too big, it becomes inefficient.
This is like getting a bigger propane or oil tank! You can load it with more wood (full rounds - no splitting!) and it will burn longer and therefore you will load it less often.
No one has ever complained and said that I sold them one too big.
In contrast, many people have said,
"I wished that I listened to you!"

| I
have never heard of this furnace until I saw this post so
I checked out the website. The first thing I noticed was
the tiny air ducts, then I saw only 500 cfm fan?! Those
two items would make me walk away and not look back. See review |
COMPARE to our 20% bigger ducts AND our 46% bigger fan! |
²
OUR Flue drops down into the firebox 14 inches, trapping in the heat and the smoke but more importantly, the gases, due to this huge secondary burn chamber, which will be burnt off; valuable heat energy that would have been otherwise lost, up the flue.
This customer did a great job, connecting his 12" insulated ductwork to the Hyprotherm Hot Air wood furnace - with a substantial shelter above it, with matching steel!
