Why buy a wood furnace with no water??

01.

NO WATER!

That means NO RUST EVER,
NO CHEMICALS,
NO WATER TESTS!

02.

TWO 2010 CFM FURNACE FANS

The thee smaller model furnaces have 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.

LOWEST COST TO INSTALL!

SIMPLE TOO! The only things needed are a thermostat wire, a 110V power wire and inexpensive 12" round ductwork.

Hot Air Wood Furnace

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.

12" Ductwork

Simple Install

12" Galvanized Ductwork

This photo shows how many people run their ductwork through a basement window, which happens to be the exact size in many instances and makes installation a breeze!

12" insulated ductwork connected to hot air wood furnace

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!

Hopsco Wadena vs Hyprotherm

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!"

 

 

Wadena / Hopsco Forced Air Furnace vs 
Hyprotherm Forced Air Furnace

Hopsco who
purchased Wadena		 Hyprotherm Manufacturing LLC
Firebox Thickness: only 3/16"
only 24/28" deep		 Firebox Thickness:
33.3% thicker at 1/4"
55" deep!
ODF1500: 780 lb ODF2000: 950 lb TW1000: 1720 lb/2069 crated
TW2000: 2220 lb/2477 crated
TW3000: 2340 lb/2590 crated
TW4000: 3380 lb/3630 crated
Blower: 
Just 1500 CFM 		46.6% larger blower: 2200 CFM
 

Heating area: ODF1500: 2,800 sq. ft.
ODF2000: 4,000 sq. ft.
TW4000: 10,700 sq. ft.

This is loading it twice a day OR ONCE A DAY heating half of that square footage. 
Duct Size 10"
 20% bigger Duct Size; 12" I.D.
Flue must be purchased separately 87.5" Flue included WITH a chimney cap²
Firebrick must be purchased! No Firebrick needed due to thicker firebox!
 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.

Having two loading doors; one on each end, makes it much easier to load a firebox that is almost 6 feet deep.  Simply open one door and load it with logs that are 30" long and do the same thing through the other door and your firebox is full!  Did you notice how you can see right though the firebox with both doors open (above)?

You don't have to handle logs that are 5 1/2" long and weigh 200 lb! 

One ash tray is on each end as well, for easier clean out.

NO SPLITTING NEEDED with all of our models!

20-year ON-SITE WARRANTY

1: 20-year ON-SITE WARRANTY!

- VERY IMPORTANT, with Hyprotherm you won't have to pay shipping back to the factory to get it repaired! We come to you for any major repair. FYI, other manufacturers will charge you to ship it back to your home after it is repaired, as well! (10-years on water jacket)
430-ton Press Brake

2: 430-ton Press Brake

We are the only manufacturer that uses a press brake to form a firebox and air jacket; both are made separately from 1 piece of metal.

Most everyone else uses 6 flat slabs of steel, with no inherent strength and that requires 12 welds and that is bad because welds are the weak spots.

This new firebox and air jacket are formed using a 430-ton Press Brake, meaning far less welds which means less potential for air leaks because leaks often start at welds; Almost as few welds as on a cylinder; Only 4 welds vs. 12 welds on a typical firebox. Three times less! 

Cast Iron Grates

Cast Iron Grates

3: Cast iron grates are a stronger option, resistant to bowing and deformation like you may get with steel grates.  $65 per grate; requiring 1, 2 and 3 grates, depending on model size.

Shaker grates, also cast iron 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.  

75 CFM forced air blower and TWO 2010 CFM furnace fan


4: TWO 2010 CFM 3-speed furnace furnace fans on each end and a 75 CFM forced air blower with damper in the middle.

Blowing oxygen under grate

5: 75 CFM forced-air induction blower, forcing oxygen up through the grate (s), just like a blacksmith's forge!

Pull-out Ash Tray

6: TWO Pull-out Ash Trays

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 trays make it easy.  These trays are 1/2 (half) the firebox depth.

HyproTherm Insulation Information

Wood and Coal Boiler/Furnace Insulation

We now have the proper insulation that the furnace REALLY needs; (we and everyone else have 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 800 degree firebox with up to R-88 equivalent with 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 Thermal Ceramics 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:

...A brave guy!  

K-factor insulation

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.
