As a test of burn times, the owner of Shaver Furnace took the thermostat off his 25 year-old furnace, so that the fire would rage at maximum burn 24 hours a day. 

Yet he still only has to load it every 12 hours. Otherwise 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

• No logs 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 and flu 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.
• 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
• Wood is cheaper than buying it for a fireplace. Instead of 12-18' wood split,
  you can put 30" pieces in this one and full rounds. That makes buying wood even cheaper.
• Designed to work with your existing heating system, be it forced air or a boiler. Works 
  excellent with radiant heat!
• 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 heats your home, garage, shop, hot tub and domestic hot water.
• The furnace hooks up to any existing hot water, gas pack, heat pump or forced air system.

Most people 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!

Lights come shipped inside the firebox,
so they don't get broken in shipping.

Get the Bugs, Dirt, Wood and Smoke outside. Your lungs will love you and your
Insurance Company will love you too!

Many people are getting 
lower insurance rates.

No more bending over, straining your back to load wood! Lever action safety latch!

A PROVEN design - since 1972!

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

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 - NO SILICONE

Now with butyl tape and rubber grommets

Think the door's not big enough?
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!

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

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

Having the chimney come down low
and stops the heat, gases and smoke from rushing right out the chimney
AND creates a HUGE 2nd burn chamber
to burn off all the gases from the wood!

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

(Most others are 3/8 - 1/2")

Over 100% thicker!

.469" Thick Steel Firebox - ALMOST HALF OF AN INCH. FREE Upgrade until August 31, 2009. WILL NOT burn through - EVER! 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 .125" and another at .1875" thick. Ours is almost .500"! Over double the thickness!

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 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 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!

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

Firebox size is 36" wide x 50" deep
x 27" high (due to ash pan in bottom). All sizes O.D.

It is totally surrounded with 230 gallons of water, top, sides, bottom, front and back, absorbing the maximum amount of heat possible!

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

The ash receptacle (and hot coals) are surrounded with water too!

The US Made pump, fan and thermostat
included, have a one-year warranty.

All furnaces come with one pump included!
NOT optional, as with others...

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 blocks to railroad ties to support it!

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

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 during the month of August! (Reg. $99)

The ash "pan" area is approx. 16" wide x 32" long and is 8" deep. It is a non-removable ash pan because 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 - 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 front and back of the firebox and the ash pan as well, extracting all the heat from the red hot coals.

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!

230 gallon tank!

Many manufacturers only use 70-125 gallon tanks! The size (water capacity) is critical when heating a larger home. 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 180F. Larger tanks also allow faster recovery and heating - plus a reserve.

Water tank is made from 1/8 thick metal (11 gauge) - 2 times thicker than many others using only 16 gauge.

1/8" is the standard in the water tank industry for any water tank.

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. This takes place of an inefficient manual draft opening.

Our furnace is so strong and well-made,
that the chimney alone is strong enough
to carry even the 2600 lb. weight of
our biggest furnace!

We move them like this every day!

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 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 adapter.

The blower in the back is a great aid
in getting a fire started. It also recovers
the water 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!
 

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 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).

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!
 

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

Kits 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. Heat exchangers are about the $202-295 (varies with size).

The average cost for installation (labor) based on average specs is $437.17

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.

Don't forget a concrete pad, approx 4" thick.

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.

5 more great color combinations (above) to choose from!

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

Start with a small piece of wood.  :o)

Seriously, you can use these bigger, cheaper pieces or smaller ones - whatever you can easily handle. The bigger ones (rounds) require less cutting and 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!

 

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

Shove the logs in on top of each other.

Use the 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!

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 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 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 37 years of experience.

Best regards,

Ben

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 37 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. Shaver 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 Shaver's Hot Water Wood Furnace.

 

We now have a dealer in the UK,
the Ukraine, France and Spain,
who will import the furnace, 
pay all duties and ship it to you!
