In the U.S., our furnaces are for Commercial applications only.

Our traditional outdoor furnaces generate economical,
natural and safe heat.

They are compatible with most existing and new heat systems,
including hot water, forced air, hydronic heat, radiant floors and baseboard heat and more.

They are built to heat buildings, garages, workshops,
commercial and other spaces, plus domestic hot water systems,
pools and hot tubs.


This Model: HyProTherm  COAL Series 185
is Rated to Heat up to 2,500 sq. ft.,
loading it just ONCE A DAY!

2500 SQ. FT. WILL GIVE IT A 24 HOUR BURN TIME,
USING A GOOD HARD WOOD LIKE OAK IN A WELL-INSULATED HOME
AND YOU WILL
LOAD IT JUST once a day!
(Instead of TWO times a day, which is normal in the industry)

FYI:

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!"


NEW FEDERAL EPA LAWS are in effect now!
and you can still purchase these COAL furnaces
for commercial purposes.


HyProTherm Outdoor Outside Wood Burning Furnace Boiler Stove


Outdoor WOOD boilers FOR A RESIDENCE
are now OUTLAWED in ALL 50 STATES!

 

              (A new FEDERAL EPA LAW kicked-in nation-wide on Jan 1, 2016)
                       
                       
              You can only purchase an outdoor WOOD BOILER
for non-residential purposes, in the U.S.
.
 Wood Boilers are still available in Canada,
the U.K., Spain, Europe and other countries overseas!


                       
              That means folks who have a shop (body, wood, auto, etc)
or
commercial business, greenhouse, barn etc.,
can still buy one of these simple and less expensive furnaces.
                       
                                     
                       
              

                                               FYI, the minimum cost is currently $11000 to $18,000 and more,
for a new EPA, smallish, typical front-loader.


People simply hate how hard they are to start
and that it's a full-time job to keep them running
because the wood HAS to be dried, under cover,
for a minimum of two years!

                         
 


Outdoor/Outside Water Boiler

HYPROTHERM COAL BURNING FURNACE

 

Remember, when wood gets too heavy, you  can easily shovel in coal!

 

These will burn wood and coal equally well!
These can save you THOUSANDS!

 


STOP! You've found the BEST! 
NO OTHER MAJOR MANUFACTURER
has a firebox that 1/2 inch thick !

Our standard firebox is 3/8" thick!
That is 50% thicker than most of our competition's 1/4"  firebox!

Many are only .125'' - .1875"

Our closest competitor is only 1/4" thick (.250) 
We're 50% thicker!

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


HyProTherm Furnace is proud to announce that ALL
HyProTherm Pro Series
185, 265, 300 AND 350 furnaces
furnaces have been tested (in their original configuration) and Certified to be 75% efficient or better
and this means that you will burn less wood than others!



~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


Check out the Best Outside Wood Boiler and 
least expensive Coal and Wood Furnace prices!

 

IMPORTANT: The water jacket bottom is THE SAME THICKNESS as the firebox because it is the most vulnerable part; 3/8" standard thickness (already 50% thicker than most) and the 1/2" THICK firebox option gives you a HALF INCH THICK water jacket bottom as well! ...NO ONE ELSE DOES THAT - ANYWHERE!! 


IMPORTANT! READ THIS!

HyProTherm Wood and Coal Boilers and Forced-Air (Water-less) Furnaces

1: We have 20-Year ON-SITE Warranty; VERY IMPORTANT so that you don't have to pay shipping to get it repaired; there AND back, like 86% of the companies require!

20  year warranty wood boiiler

2: It is the best outdoor wood boiler because it has up to a 25% BIGGER FIREBOX giving you more wood capacity which means heating more square feet with LESS LOADING! 

3. This new firebox is formed 
using a 430-ton Brake Press, giving you one piece of metal for three sides; meaning less welds which means less potential for leaks because leaks often start at welds. 

Almost as few welds as on a cylinder; Only 4
main welds (2 for the end plates and 2 to mount the firebox to the floor vs. 12 welds on a typical firebox. Three times less means less potential failures and leaks!

4: Not only is the firebox thicker than others
 (3/8" and 1/2"); 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 - ANYWHERE!! 

5: It is the best wood boiler because
Our Water-less Furnaces have Pull-out Ash Trays too!

 Ash Tray wood boiiler 

6: It is the best wood boiler because it has ALL Off-the-Shelf PARTS; nothing proprietary that you have to get from us.

7: It is the best wood boiler because it has No electronics; NO circuit boards, NO computerized parts  (like on the Wood Master and Central Boiler and many others)!

8
: It is the best COAL boiler because it has the superior cast iron grates on all but the wood models.

cast iron grates wood / coal boiiler 

9: It is the best wood boiler because it has one pump installed WITH flanges; many others don't even give you one pump PLUS our wood boiler has an extra set of ports for another pump to heat another building, shop, garage, pool, hot tub, driveway, walkway, greenhouse, etc.

wood boiler pump installed

Comes with water level gauge, analog thermometer, PRE-WIRED RANCO thermostat to control temperature swings to within 3 degrees, solenoid activated damper on 75 CFM forced-air induction blower, one pump standard plus an extra pump mount and return for a second pump.

10: It is the best coal and wood boiler because it has a 
nice big blower (75 CFM) in the back, to blow air (oxygen) up through the grates, just like a blacksmith's forge! Absolutely necessary for COAL and the best for wood! 

You get a real nice hot fire so that there are no unburned pieces of wood or coal left over (like on a Central Boiler)

Comes with a simple solenoid activated damper too, (shown below) for less wood consumption!

wood boiiler combustion  fan 

11. 
It is the best wood boiler anywhere because it has a 
BUILT-IN HEAT EXCHANGER to heat your domestic hot water, (below) so you do not need to purchase an external heat exchanger to mount on your hot water heater, such as side-arm or plate exchanger because it is included with your purchase of this boiler and works phenomenally well! This saves you about $300.00 and you don't need an anti-scald valve!

wood boiiler hot water heat exchanger 

This slashed my electric bill by one third instantly, when I hooked up this wood furnace to my hot water heater! 

That is a HUGE savings!


EVERY WATER FURNACE comes with
a built-in heat exchanger  to heat your domestic hot  water
PLUS the cold weather package for FREE (normally $99).

No separate domestic Hot Water heat exchanger is needed
Nor is a tempering or mixing valve needed, to avoid scalding water!!
This saves you almost $300.00!

You also get a thermostat to  control the water temperature in the furnace, automatically -
along with a NOW BIGGER 75 CFM induction blower fan, in the back,
to feed air to the bottom of the  fire, like a blacksmith's forge.

This new 75 CFM fan that comes with an automatic damper -  a simple solenoid activated damper;
to open and close 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!

ALL  the parts are off-the-shelf parts that can be purchased ANYWHERE!
No proprietary parts; you DON'T have to come to us to get a replacement part.

A shaker grate can help get rid of the clinkers.

 

 
                 
For those who are interested: Can burn ALL Grades/Sizes of Coal
                                               
                                                                                                                                                                                                           
Anthracite – this type of coal has the highest percentage of fixed carbon and a lower percentage of volatile material than all other coals, making it harder to ignite. However, when it is ignited, it burns relatively smokeless. 
               
The most well-known anthracite mines in the United States are in western Pennsylvania. 
               
                                    Anthracite Coal
               
Bituminous – Bituminous coal is the most abundant and most widely used coal. This is the type of coal found in the Appalachian region. It has a higher heating potential and is used for making coke. It has a higher  percentage of fixed carbon, greater heat value and better weathering characteristics than lignite and sub-lignite coals.                
               
Most of the non-metallurgical grades of bituminous coal are burned in boilers or furnaces to obtain thermal energy for generating electricity. Because bituminous coal is softer than anthracite, it is often referred to as soft coal.  It does emit smoke as it burns, unlike anthracite.
                 
However, there is a region in Southern West Virginia where the bituminous coal burns relatively smokeless. The Smokeless Coal Fields of Southern West Virginia are unique in the world.
               
                                    Bituminous Coal
                               
Sub-bituminous – A lesser grade of coal, it has more moisture and less carbon than bituminous.

Nut Coal - Very small coal - about 1/4" in size. See important note below.
               
                                

               

 

 
           

                                    You must notify us, if you plan on using "NUT COAL",
            rice coal or pea coal, as they are all very small,
            SO WE CAN GIVE YOU A DIFFERENT GRATE

           

                        You cannot burn "run of the mine" coal, without voiding the warranty
            because it burns way too hot.

           
           

            In the United States, the coal power plants
            generate 50% of the electricity produced.

That's the way we always move and unload them
when we deliver them, every day  :o)

 On-Site 100% paid for 5-years

*20 years on the firebox and 10 years on water jacket. 
     

 

 

Who else offers that,
who has been around 49 years?

NOBODY!

A lot of warranties only cover parts (not even labor)!
OR/and
You have to ship the furnace back to the factory
- at your expense.

Kind of negates the warranty, doesn't it?

 

                 


A gentleman called me and told me his
2-year old C_____l B____r was leaking!
It had rusted right through and they would repair it
"under warranty" for ONLY $3000 - $3500! 

 Another customer paid $700 to  ship his furnace back
and was only allowed $100 towards a new furnace
because  they only cover parts any ways - not labor!

You see, YOU have to ship it to them
and then YOU pay for shipping back to you
AND you are without your furnace for 2-3 weeks.

       

 



(It's easy to ship you a piece of metal and tell you to weld it in
and even EASIER to make YOU pay through the nose!)

Why buy a HyProTherm Outdoor Furnace? HyProTherm The others
We make it simple without expensive electronics to break down NO
We make it user serviceable. Anyone can maintain our furnace! NO
We use a common Ranco thermostat available at almost anywhere. eBay for one; not a $300 electronic circuit board NO
We use a simple mechanical fill valve - not electronic. Just flip it on for 20 seconds, once a week, when you are out there   filling it with wood. NO
We make our firebox to last! Ours is 50% thicker! .3/8   vs 1/4" 
 We have 1/2" option too.
NO
We give accurate BTU ratings using an established scientific formula. They say what sounds good. NO
We have a 2-light motion detector flood light on the front NO
We have an induction fan not a dismal damper to fuel the fire with oxygen. More complete burning! Some
Our fan is in the back, behind a door, 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? Only one other
Customer Easily Replaceable POTABLE Hot water coil. Most others don't even have one; making you buy a $300 heat exchanger to mount on your hot   water heater,! NO
Our pump only runs on demand NOT 24 hours a day as with the others! NO
We have been building fine energy efficient   furnaces for 49 years! NO
Our wood grate uses 3/4" Bar Stock! Our COAL   grates are cast iron. Many others don't even have  any grates. NO

This Model: HyProTherm Coal Series 185
is Rated to Heat up to 5,182 sq. ft.
OR 2600 sq. ft. loading it just ONCE A DAY!

185 gallon tank!

 

$7997

The owner heats his 
Older 5000 sq. ft. home
AND a 500 gallon hot tub
AND his Hot Water
AND a shop

...with a 27 year-old model!
 He is in a  temperate climate (North Arkansas).

Severe climates should rate this at 4500 sq. feet in a well-insulated home.

 

BURN TIMES

As a test of burn times, the owner of 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. Normally, he goes as long as 24 hours without reloading it.

A customer called and told me he goes  18 hours between loads (1/17/08)

Don't believe the hype and misinformation about 42-98 hour burn times. 
 
 This is only true in the summer.

See my eBay report

Why buy a wood or coal furnace?

  • No logs or coal to carry in means no messy ashes and bugs in the house!

  • One of the selling points of an outdoor furnace is the convenience of locating it near the
    wood fuel source
    so you don't have to cart wood all around.

  • Safety

    • 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 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 than a small indoor unit.

  • No inside oxygen is used to fuel the heat like other wood or gas burning units.

  • Water heat does not dry up your sinuses and eliminates respiratory problems caused
    by burning wood indoors

  • Coal  is cheaper than buying any kind of fuel!

  • Designed to work with your existing heating system, be it forced air or a boiler. Works 
    excellent with radiant heat! SEE OUR BOILER INSTALLATION PICTURE below

  • 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!.

  • One unit can heat your home, garage, shop, hot tub, driveway, walkway, pool, hot tub and domestic hot water.

  • The furnace hooks up to ANY existing hot water, gas pack, heat pump or forced air system.  (no steam)

Most people pay  for their furnace in 1-2 years!

Imagine getting a 50% return on your money!

Where else can you get that? An outdoor furnace is the BEST  INVESTMENT!

    We feel we build the safest furnace (nothing electrical outside). We have      the BEST PRICES, the simplest furnace and a Very Friendly Staff to help you every step of the way.

Outdoor Wood Burning Furnace Motion Lights

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 switches. No forgetting to turn it off. If  it's dark outside and you go near the furnace, it turns on!

   

New, nicer looking furnace!

Now with nice neat grommets


Outdoor Wood Burning Boiler Door

TWO FOOT X TWO FOOT
INSULATED DOOR!


Coal can be thrown in easily, without strain, by the shovel load... 

 Using wood for your shop, garage or pool? 
 Just a 15" round log, 
30" long, will weigh 112lb  
- 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!

 

26.5" x 26.5" DOOR with a 24" x 24 Opening

The TOUGHEST door you'll ever find with        TWO 1/4" solid steel plates separated by a 3" air shield.        There is also the astounding Superwool insulation BETWEEN the plates!

This 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 just by itself!  

       Very heavy duty motor mount style hinges!

      OUR DOORS won't fall off, unlike some others out there!

<< STAY COOL HANDLES!

The temperature of the door is only 1ºF with a 700ºF fire inside and an outside temperature of -10ºF, thanks to the SUPERWOOL INSULATION!

     

 


Outdoor Wood  Furnace Firebox
     
     
1/4" thick flue (as thick as most people's fireboxes) 
      will not
get damaged by throwing wood in

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!
     
     
No complexities
or hard starting issues
NO computerized parts. 


      Will burn ANY type of coal.

Cast iron coal  grate

STANDARD Cast Iron Grate

The removable grate ($65 less)
is made out of 3/4" inch bar stock.

Now THAT's thick! (Most others are 3/8" - 1/2")
     

1/2 inch Firebox option 
50% thicker!

.500" Thick Steel Firebox - 5/10th OF AN INCH. WILL NOT burn through - EVER  - even burning red hot coal! Will not crack or split like  stainless steel!

Compare Firebox thickness to  another popular furnace (eBay won't allow us to say their name) at only 0.0625 or 1/16" thin!  This is typical of Stainless Steel.

Others are just .125"  and another at .1875" thick.
Ours is 3/8th inch with an optional 1/2" thick firebox AND water jacket bottom; the most vulnerable part!!

We have a removable ash pan! Some other makes don't even have GRATES or an ash pan at all!! That makes it HARD and dangerous to clean out! You have to let the fire die down  or move the burning wood aside (yea - right) to scoop out the hot ashes. OUCH!

Similar to a cylinder for a firebox. We just have to weld the end plates on because we use ONE PIECE OF STEEL to make the firebox, using a 430-TON press brake! 

Then we weld it the bottom of THE SAME THICK METAL (3/8" OR 1/2" THICK)

It WILL NOT RUST through in a lifetime! Will not  get stress cracks causing a major leak like Stainless Steel!

We have furnaces 30 years old and more, still in use today!

only minutes after reloading with wood!      

 

      Hyprotherm 185 Firebox size is 
      30" wide x 34" high x 34" deep (long)
     
      All other models, except for the Hyprotherm 85 model have the same width and height. Only the lengths change.
     
     
Hyprotherm 265 Firebox size is 50% bigger 
      30" wide x 34" high x 50" deep (long)
     
     
Hyprotherm 300 Firebox size is 
      30" wide x 34" high x 58" deep (long)
     
     
Hyprotherm 350 Firebox size is DOUBLE of the 185 
      30" wide x 34" high x 68" deep (long)
     

      They are all surrounded with 185-350 gallons of water; absorbing the maximum amount of heat possible! Model number is how many gallons the boiler will hold.

The chimney is also surrounded by water, capturing heat that would otherwise be lost!



wood boiler pump installed

 


 
INSTALLED PUMP, with FLANGES.
Two-year warranty! Forced-air fan 
and a Ranco thermostat with display, is included
along with an analog thermometer.
Water level gauge, top left.
All parts are available everywhere.

There are NO proprietary parts or circuit boards!      

 

Comes STANDARD with TRIPLE Hookup for heating a Home AND a shop / garage / apartment AND potable domestic Hot Water too!

NEVER run out of hot water again!

CONSUMER REPLACEABLE  and cleanable Potable Water Coil (50 foot long copper coil) carries hot water, heated by the water reservoir directly to your hot water heater. We show you how! No separate plate or side-arm heat exchanger is needed!! No mixing valve is needed to avoid scalding water on your hot water heater, because ours is thermostat controlled! This saves you  up to $300.00 and is SAFER! 

Again, this is potable (drinkable) water.

Pumps run on demand NOT 24 hours a day like others! 

 


There are legs on the bottom with the siding surrounding the bottom to ground level.

A pad is recommended but you can use solid concrete blocks or railroad ties to support it!

 

We use state-of-the-art Solar Guard insulation all around the water jacket PLUS vinyl-backed fiberglass bats!

Solar Guard is only 1/4" thick but combines a thermal break, reflective insulation and an insulating layer of R11.6! It has backing on both sides and is aluminum foil backed on one side. We then insulate on top of that with R11 vinyl-backed fiberglass in the walls and ceiling! 

TRIPLE INSULATED (R50) ON TOP - like a passive Solar house. You cannot feel the heat when you touch the siding!

That gives you R22.6 in the walls and now R50 in the ceiling!

FREE NOW! (Reg. $99)

Outdoor Wood Burning Stove



The removable ash is approx. 16" wide x 6" deep x 30"to 64' long (varies with firebox size) . It is a removable pull-out ash pan because
it is the easiest way to clean out the ashes!

WARNING! Some other makers don't even have an ash pan OR have grates! 

You have to let the fire die out or shove the hot burning logs aside - then clean it  out while the firebox is 700 plus degrees - and then restart the fire in the dead of winter! Who wants to do that?

Water surrounds the top and both sides of the firebox AND the chimney as well, extracting all the heat possible.

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. 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.

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

Another advantage is that the chimney exits through the water, further heating it up - for free! Nothing does better!

Red Outside Wood Burning Stove

Barn Red or Brick Red with Black Corners

 

185 gallon tank!

Many manufacturers only use 60-125 gallon tanks! The size (water capacity) is  critical when heating a larger building. Too little water means not enough BTU storage for the cold, windy days!

DON'T BELIEVE it when they say they can heat 4,000 sq. ft. and have 300,000 BTU.

That's scientifically impossible without heating the water to over 300 degrees!

We can heat a house with a water temperature as low as 130 degrees as opposed to 160-180 degrees in a competitor's with a smaller tank.

However, our thermostat is adjustable up to 180°F but no need to run it over 150°F, unless you have a boiler - SAVING  YOU FUEL (WOOD)!

Larger tanks, like ours, also allow faster recovery and heating - plus a bigger reserve for those really cold days.


Water tank is made from 3/16" walls and 3/8" or 1/2" thick WATER JACKET BOTTOM; the most vulnerable part! MANY time thicker than many others using only 16 gauge.

1/8" is the standard in the water tank industry for any  water tank. We are 50% thicker and tree to four times thicker in the bottom. NO ON ELSE DOES THAT ANYWHERE!

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 to keep the water at a set temperature that you can  adjust.

We have an  automatic fan now, that is 75 CFM versus 50 CFM. It now comes with a  solenoid activated damper, which slams the door 100% closed, when the fan  turns off -  so that no air is bleeding into the firebox.  

 This  totally eliminates any kind of fire or flame smoldering,  so that you burn  less wood (according to our many customers)  and you get better temperature  control because there is no heat coming from the firebox,  that is  otherwise unregulated.

     

 

Water fill valve with overflow tube around the corner and to the left, shown with 3/4" thick heavy duty poker; 3' long plus handle. Easily push 3 foor logs all the way back into our biggest boiler, that has a firebox just shy of 6 feet.

Simply pick one day of the week like Saturday and open the valve until you see water run out of the overflow tube (too left of valve).  You will know that it is full but there is also a water level gauge in the back of the furnace behind the full-sized 4 foot  wide door.

Hanging Outdoor Wood Burning Furnace

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 furnace!

We move them like
this every day!
     

 

ALL FURNACES!

Exterior is made of Heavy Duty Siding - 29 gauge structural quality, full-hard steel. 10 layers of protective coating. It has a
Lifetime film integrity Warranty for walls and roof and a 30-year warranty against fade and chalk. 10 year edge rust warranty against acid rain.

 17 colors to best suit your surroundings! Mix and match the roof, sides and corners.

There are legs on the bottom with the siding surrounding the bottom to ground level.

Concrete pad is recommended but is 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 water. It tops out at about 90" feet above ground. You can EASILY add 6" regular stovepipe extension(s) with our  free adapter. (We will simply trade the standard free chimney  cap for the adapter, since you will be using a different chimney cap, when  you extend your flue pipe.)

View through ash pan door and you can see the air blower inlet (seen  in back of this picture).

 

Blower Inlet Outdoor Wood Burning Boiler

Click on Picture
for a larger image

The blower in the back is a great aid in getting a fire started. It also recovers the water temperature much quicker - just like a blacksmith feeds his fire with oxygen!

 

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.
     

 

The air blower determines how hot the fire burns and therefore how hot the water gets.

A thermostat on the back of the water jacket tells the blower when to turn on and off, so it doesn't run all the time and waste your 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).

COAL MUST have air/oxygen blown in  from the bottom. A fan on the front door (like so may others) will not  work!

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!

     

 

           
     

      Installation Kit      

Items can be purchased locally or supplied by your local plumber. The BEST PRICES are right on eBay though!

Most people will spend an average of only $450 for all of their installation parts including the heat exchanger to heat their home, plus their Pex pipe at $6.15 a foot for FOUR PEX pipes, wrapped with insulation and put into a 4 inch black tile pipe, ready to drop into your trench.

The average cost for installation (labor) based on average specs is $437.17 but a handyman or your  own labor is all that is needed!

If you do some work yourself, it would be a lot less. Many places allow you to be your own contractor.

This will vary depending on your
local rate and location.

Kit costs will vary depending on the number of feet from your house. 

 Other variables include heating your hot water or adding a 2nd heat exchanger for a separate building. This will require more pipe and a separate pump and thermostat in most cases. 

 Pumps are $99 each; std size. 
 Heat exchangers average $169 ($136-200 - varies with size)
.


Don't forget a concrete pad, if possible, approx 4" thick. However, you can also use sold 4" blocks or pavers instead and even railroad ties. We just need to distribute the weight because front-loaders can weigh over 3 TONS when full of water! 

 

It will take only ½ yard for a 4'x10' pad
(approx 4" thick), giving you a nice place to stand pile wood and load it.

      Many people can pay for their furnace in
      a year and a half of oil or propane bills!
 
     

Start with a small piece of wood.  :o) 
BUT you CAN burn whole rounds, with NO SPLITTING needed!

Seriously, you can use these bigger, cheaper pieces or smaller ones - whatever you can easily handle. The bigger ones (rounds) require less  or NO cutting and splitting so they cost less - about 80-90 a cord in most areas.

ANY wood or coal is cheaper than oil, gas and electricity!

One person said that they have never used their propane heater after propane prices tripled!

 

            A fire in minutes!            

Whole rounds burn longer and cleaner and it's
SO NICE not having to split the wood!!
     

 

     

You can burn ANY coal, regardless of size.

Shove the logs in on top of each other or shovel  the coal onto the grate.

Burning coal and wood together works extremely well according to our customers  but
remember, you cannot use wood in a coal furnace for  residential purposed, in the U.S.

Use the poker (provided) for safety to push the logs in.

That big thick strong poker comes with the furnace - for FREE!


Thought there wasn't a fire?

Think again!

Within a couple of minutes - literally - this fire was roaring, thanks to our forced induction  fan that comes free with every furnace!      

 

 

This new design of hot water coil cover
allows the water level to be much higher allowing rust protection
even to the top plate PLUS more water = more BTU storage.

The old design (top) was about 2 inches lower,  leaving an air gap
and less water/BTU storage to heat your home,
even if the fire goes out.

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 furnaces still in use after 30 years plus!!

1. Mild steel transfers heat better than stainless does.

2. 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.

3. 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 is almost .500 inches thick (HALF INCH) as opposed to .200 in many furnaces. Just 31 thousandths shy of 1/2 inch!! They never rust through.

We just replaced a H_rdy a week or so ago and there are many leaking Ce___al Boilers and H_rdys on eBay for sale, that are leaking.

4. Stainless is more prone to stress cracks, so why use it?

5. Unless the stainless is retreated after welding, you've lost all of it's 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 43 years of experience.

 


.
SAFETY!

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., on the outside. 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 38 years of use.

We do not have complicated self-fill, or water level indicators on our furnaces. They are simply things to wear out or malfunction requiring costly service and repairs. We install a simple manual valve which you turn on until water runs out the overflow, and flip back off. SIMPLE! (This takes about 10-20 seconds.)

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. HyProTherm has sold several thousand in their county alone! We are sure that if you purchase one of our stoves you will be completely satisfied with our stove throughout its long service life which you will enjoy.

Hot Water Wood Furnaces are indeed the very best heating choice. We are positive that a few years down the road when others are making costly repairs to the overly complex system they purchased from our competitors, you will be quite comfortable and enjoying your new cost effective,  economical HyProTherm Hot Water Wood Furnace.


 

 


About us:

HyProTherm Furnace is a privately held company and was established in 1972. a Heating and Air company preceded it and dates back to 1950.  Billy 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 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! Stick something like a heater core from a car in the plenum and it  would radiate heat - and the hot water could be pumped from the outside. He developed a model for himself and continued to improve on it over the years. In  1972 he decided to start selling the furnaces and an industry was born. Our wood furnace (now HyProTherm) was indeed the first. The last revision was made in 2017 and the furnace  remains a leader in the industry with amazing innovations, today. Now Gerald's son Billy heads up the  business.

 

We have been in building boilers in the same factory for 49 years and we are a family run business.

We have sold THOUSANDS of furnaces across the country. 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.
