DYNAMIC DUCTWORK STORES ENERGY

TECHNOLOGICALLY FOAMED SELF INSULATED AIR DUCT SYSTEMS

 

It is unique to other materials because it is manufactured with food grade plastic that is safe for humans and the environment.
The material is mixed with a foaming additive during manufacturing to achieve the density and performance parameter desired.
The preformed ductwork has the characteristic of a smooth low friction surface that is resistant to mildew, mold, and Radon;
under pressure it will not crack and is non-toxic and recyclable. In addition, the ductwork is self-insulating, adjustable and easy to install.
A thermal efficiency performance of TheBlueDuct™ has a test proven equivalency for delivery effectiveness comparable to underground coated spiral ductwork wrapped in R10.

You can also use standard galvanized pipe with insulation shown below.

Shaver has done it again! Backed by our 40 years of experience, we have developed a FORCED-AIR FURNACE that doesn't need water!

Comes complete with a forced-air draft fan and automatic damper to fuel your fire with oxygen, plus a big, full-size furnace squirrel cage fan (1500 CFM or 2000 CFM, depending on model)

- IDEAL for any home or shop without an existing heating system! No furnace? No ductwork? No radiators? No boiler? No problem!!

- Excellent for those people with cabins or homes that are left unattended because the water won't freeze; there IS NO WATER.

- Use our built-in furnace fan instead of an air handler or using your current furnace fan!

- Before spending thousands of dollars on a new furnace for your garage or shop, plus many more thousands for fuel - choose a ThermoWind  and heat for Virtually FREE!

- Eliminate the threat of a fire, by having the furnace away from the house, just like with our outdoor wood fired WATER furnace (often called a "boiler".

- Do you want an indoor wood burning furnace for your attic or basement? Try our outdoor wood burning furnace instead; No carrying wood into the house, along with the bugs, bark and trash.

- NO SMOKE in the house either!

- Hook up our outside wood fired furnace to your central heating ductwork!

Only a forced air furnace inside your home can be used because ductwork is needed, so an electric, gas, oil. propane furnace, etc, and heat pump or geothermal system can be used.

No boilers or radiant floor heating systems can be hooked up. However, you can add ductwork to any building (or not even use any ductwork) to heat a building.

We can even help you if you don't have any heating system now!

___________________
 

In case of a power failure,
you can still have a nice warn house,
when everyone else is cold!!

ONLY  in the case of power failure and if you want heat, it requires a 2000 Watt Generator for the
ThermoWind 1000 model (only $200 at Walmart)
or a standard size portable 4000 watt generator for the ThermoWind 2000 model, (because of the startup power that the motors take), with plenty of power left over for lights, etc.

ONLY needed in case of a power failure; NOT needed for everyday use.

This furnace can go outside and does not have to be bolted to the house or go in the basement like many other models out there!

Heat is carried to your home through insulated 12" pipes, buried underground or you can use regular and less expensive regular ductwork and insulate yourself.

According to the UL (Underwriters Laboratories) our furnace needs to be 5 feet away from flammables. The ThermoWind units cannot generally be more than 15 feet from your home because the temperature losses and airflow losses but in no case can be more than 30 feet away from your existing ductwork.

You only need ductwork, a thermostat and thermostat wire plus a power wire to install. DO IT YOURSELF!

No more worries about frozen water!

NO CHEMICALS or annual water tests! No pumps!

Also perfect for folks who have power failures often (you would need a generator to get heat but there is no worry about frozen water, etc)

NOW there is no need to put the furnace right next to the house or in the basement with our revolutionary insulated underground pipe!

These air pipes are only 12" in diameter so a standard backhoe with a 24" bucket can easily dig a trench for the two pipes to lay side-by-side.

We are the only manufacturer that has this!

  • Air & Water Tight

  • Foamed Walls on underground pipe.

  • Easy to Install
     

  • Quiet and Efficient

  • PVC FREE ductwork

THE SHAVER OUTDOOR WOOD BURNING FURNACE


How does an outdoor furnace heat my home?

The Shaver Outdoor Wood Furnace is designed to save the absolute most energy and provide the most comfortable heating available; not dry. It heats your home by heating a firebox surrounded by a steel air chamber. When this air chamber reaches a preset temperature a fan controller turns on the main circulation blower (our built-in furnace fan). This blower forces the air into your existing central duct system. Can also be used without any existing ductwork.

How do the Thermostat Controls work?

The only visible addition to the heating system inside your home is a 2nd thermostat, which is located near the existing thermostat, where possible. This thermostat actuates the combustion blower of your outdoor furnace to fuel oxygen into the smoldering fire.. When the air inside the air chamber reaches the optimum temperature, a fan controller turns on the main circulation blower. This blower forces the air into your existing central duct system (if you have any). The original wall thermostat turns on your original furnace, if the outside wood furnace is not in operation. Your existing furnace will take over
automatically, to maintain your household temperature.

This is good if you can't get home to fill the furnace with wood or if you go on vacation. No switched and no relays to make this happen.
 

 



Two buried 12" pipes carry the heat to the house
and the cooler return air comes back.

This is standard steel duct wrapped with insulation.
The insulated underground pipe looks different than this.
 See DUCTWORK below and black pipe kit above.

 

We are the FIRST in the industry to have
special insulated underground ducts!

Why buy an outdoor wood furnace?
  • No logs to carry in = no messy ashes and bugs in the house!
  • You can have your outdoor furnace conveniently located it near the
    wood pile, so you don't have to carry 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.
    • The chance of chimney and flue fires is eliminated, in your home.
  • 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, propane or oil bill. 
  • An outdoor furnace requires less tending than a smaller indoor wood stove or insert.
  • 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. No dry air either.
  • Wood is cheaper than buying it for a fireplace. Instead of 12-18' wood split,
    you can put 26 or 40" pieces in this one and use full rounds.
    No splitting wood; that makes buying wood even cheaper.
  • Burning wood, a total renewable resource, is much 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 in many cases, FREE!.
  • The furnace hooks up to any existing gas pack, heat pump or forced air system
     - or can be used without any exiting heating system or ductwork.

Most people say that they pay for their furnace in 2 years or less! 
Imagine getting a 50% return on your money!
Where else can you get that? An outdoor furnace is the BEST INVESTMENT EVER!

 



You've found the BEST! 

Our standard firebox is 50% thicker
than most of the competition
at 3/8" thick.


Many are only .125'' - .1875"

Our closest competitor is only 1/4" thick (.250)

We have the BEST PRICES 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 (black or white), for ease
and safety when loading your wood at night.

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 looking butyl tape and grommets.


Outdoor Wood Burning Boiler Door

Think the door isn't big enough?
A 15" round oak log, 26" long, will weigh a whopping 97lb
 - 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!

18" x 18"  - The TOUGHEST door you'll ever find with TWO 1/4" solid steel plates separated by a 3" air shield AND insulation. 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.

There is fiberglass insulation BETWEEN the plates now!

Very heavy duty hinges! OURS won't fall off!

 

Shaver Outdoor Wood Burning Furnace Firebox

Click on Pictures for a Larger image
1/4" thick flue pipe - will not get damaged by throwing wood in it.

 

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! Nothing does better!

These are some of the reasons that our water furnace qualifies for the Federal TAX REBATE using the exact same design!  (The forced-air furnace does not qualify for the tax rebate because we have not tested it)

This also means that you will burn less wood than with other manufacturer's furnaces, who don't qualify for the rebate and therefore you will use more wood - being less than 75% efficient. That's proof, not just rhetoric.


Over 50% thicker!

.380" Thick Steel Firebox (3/8") - WILL NOT burn through - EVER! Will not crack or split like stainless steel!

We have never had a firebox failure, crack, split, rust-through or leak in 39 years of making the 3/8" thick firebox. After all, it is 50% thicker (or more) than most of the competition!

Compare Firebox thickness to another popular furnace at only .125" and another at .1875" thick. 

We have an ash pan! 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. OUCH!

Only one factory seam in tube so it doesn't weaken the structure, break or warp. It is made of a solid piece of tubular steel (drill casing)! It is X-rayed before it is shipped.

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

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

 

3/4" grates for Outdoor Wood Burning Furnace

The removable grate is made out of
super thick 3/4" inch bar stock.
We have NEVER had one burn through!

Most grates (if they have them)
are only 3/8" - 1/2")

 

 

Outdoor Wood Burning Furnace Ash Receptacle

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 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 Shaver will exceed that temperature.
 <  View through ash pan door and you can see the fan blower inlet (seen in back of this picture).

The fan 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 off and on (and has a solenoid activated door/damper), so it doesn't run all the time and will not 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 - just like a blacksmith's forge. That's better than blowing in from the front door (very obvious when you see that big box on the door) and into the side of the fire, as all the others do (if they even have a fan).

You get more complete burning fire when the oxygen is fed through the bottom!

 

Outdoor Wood Fired Forced Air Furnace

Actual photo of a fire inside our firebox,
only minutes after reloading with wood!

Firebox size on the Thermowind 1000 is 36" wide x 28" deep x 27" high (due to ash pan in bottom). All sizes O.D.

The air chamber totally surrounds the firebox, top, bottom, sides, front and back - unlike others.

The chimney is also surrounded by air, drawinf off heat.

The ash receptacle (and hot coals) are surrounded with air too, in the bottom!

 



Forced air fan for home (left) and forced air fan for furnace with solenoid activated damper fan. 

 

 

Forced-Air Damper and fan

The fans and thermostat
included, have a one-year warranty.

1500 CFM blower on left above.
2000 CFM on the ThermoWind 2000

You get a solenoid activated damper too, INCLUDED!

Most parts are available everywhere.

There are NO proprietary circuit boards!

In case of a power failure, you can still have a nice warn house, when everyone else is cold!!

Requires a 2000 Watt Generator for the ThermoWind 1000 model
and a standard portable 4000 watt generator for the 2,000 model,
(this is because of the startup power that the motors take),
but you will have plenty of power left over for lights, small appliances, etc.



You MAY need an heating and air guy to hook up the duct work, but all you really need is an adapter from a round 12" pipe to your rectangle (usually) pipe..

Flanges to connect outside duct to indoor furnace

Everything is very simple and easy to do. There is a comprehensive manual, with lots of pictures and diagrams, that will help you every step of the way. You can also call me or the factory for assistance.

 

 

Outside Forced Air Wood Fired Furnace NOW there is no need to put the furnace right next to the house, with our exclusive insulated underground duct!!

Eliminate the threat of fire by having the furnace well away from the house just like with our outdoor wood fired WATER furnace.

We are the only manufacturer that is doing this!

Perfect for folks who often have power failures or those people with cabins, shops or homes that are unattended.

The two connectors in the back hook up to the
blue pipes which are buried in the ground. 

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.

  • Air & Water Tight

  • Foamed Walls

  • Easy to Install

  • Quiet and Efficient

  • PVC FREE

  • GREEN BUILDING Approved Adhesives

 



Ideal for new construction, as you can see here
 but you will just need two pipes running to the house
in an existing structure to connect to your ductwork;
one supply and one return.



Outdoor Forced Air Wood Burning Stove


The ash "pan" area is approx. 16" wide x 32" long and is 8" deep. It is a non-removable ash pan and it is easily cleaned at the front, through the door with a small shovel or hoe.

WARNING! 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 (yeah, right!), then clean it out while the firebox is 700 plus degrees - and then restart the fire in the dead of winter! Do you want to do that?

Air surrounds the front and back of the firebox and the ash pan as well, extracting all the heat from the red hot coals.

 

There is an fan/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 draft opening.

 

Fored-Air Outside Wood Burning Furnace

 

Hanging Outdoor Wood Burning Furnace

Our furnace is so strong and well-made,
that the chimney alone is strong enough
to carry even the 2000 lb. weight of
our biggest forced-air furnace!

We move them like this every day!

The 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.

 20 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 not necessary.

Use railroad ties, solid concrete blocks/pavers.
 

The chimney is made out of Schedule 40, 1/4" thick, solid steel pipe and is surrounded by air as well. It tops out at about 90" feet above ground. You can EASILY add standard 6" stove pipe extension(s) using our adapter.
Chimney/Flue Adapter


Solenoid activated damper

Super easy access!! 

Some other manufacturers have to
have the whole hull removed by 2-3 people
to access these components!!

There is an extra large rear access hinged door. All electrical items are in back, safely behind the door/lid! 

Shaver has easy pipe (air duct) hookup and electrical hookups (simple 110V wiring). 

No special tools needed.

The easiest furnace for the self-installer to put in!

We help you every step of the way!

 

Carrying log of firewood

Many people can say that they can pay for their
Shaver forced-air wood furnace in
2 years or less of propane bills!
 

Start with a small chunk of wood.  :o)

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

ANY wood 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 to have to split the wood!!

Shove the logs in on top of each other.

Use the 6 foot poker (provided) for safety to push them in.

That big 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!

 

 

 

Outdoor Forced-Air Wood Burning Furnace

We use state-of-the-art Solar Guard insulation all around!

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 in Northern U.S. states and in Canada and Alaska.

Questions about stainless steel answered


Do you build with stainless steel?

Hi! 

No, we don't build stainless for several really good reasons.

Our furnaces last longer than most stainless furnaces, with MANY of our water 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 (which will rot and fall off).

There are many cheap grades of stainless out there.

3. Since stainless is so expensive, the fireboxes are made really thin. Some are no thicker than the metal of a trailer fender!! That's why you see so many split and broken apart.

Our firebox is almost 4/10th of an inch thick, as opposed to .200 in many furnaces. They never rust through.

We replaced several stainless steel Hardys and there are many leaking Central Boilers and Hardys on eBay for sale.

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 40 years of experience.

Best regards,

Ben
