Discover WHY we can say that.


Most important!
We build our firebox 50% thicker
than our nearest competitor. Ours is 
.380" thick - almost 4/10th of an inch!
That's why they don't rust through,
split, crack and warp!

We don't ANY fancy electronics or circuit boards.

ALL of our parts are off-the-shelf parts,
that are available anywhere.
There's nothing proprietary that you have to buy from us.

Many companies don't have a forced air fan.
Others have a fan that blows air through
the front door into the side of the fire.

We took it one step further and have a fan in back,
that blows air up through the grates
and feeds oxygen into the bottom of the fire,
just like a blacksmith's forge!

Our warranty covers parts AND labor!
May warranties only cover parts or
you have to ship the furnace back to the manufacturer!

Rated to Heat up to 4000 sq. ft.

However, the manufacturer heats his 
Older 5000 sq. ft. home
AND a 500 gallon hot tub
AND his Hot Water
AND a shop

...with a 25 year-old model!



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 loading it.

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

Why buy a wood furnace?
  • 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.
    • The chance of a gas explosion from your furnace in your home is eliminated.
    • Indoor pollutants of harmful gases and fumes are eliminated.
    • 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.
  • One unit heats your home, garage, shop, hot tub and domestic hot water.
  • The furnace hooks up to any existing hot water or forced air system.

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

Extra large, waist high loading door.

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

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.


ALL furnaces now come with a double flood light on the front for ease of loading the wood.

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!



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.

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


Click on Pictures for a Larger image

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


.380" Thick Steel Firebox - ALMOST 4/10 OF AN INCH.
WILL NOT burn through - EVER!

Compare Firebox thickness to another popular furnace (eBay won't allow us to say their name) at only .200"
Ours is almost .400" ! 

Some other makes don't even have an ash pan!! It 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.

50% thicker!

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 !

It will not RUST through in a lifetime! Will not split and crack 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 34" wide x 27" high (due to grate in bottom) x 34" deep. 

It is totally surrounded with 170 gallons of water, absorbing the maximum amount of heat possible!

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

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



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


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

CONSUMER REPLACEABLE  Potable Water Coil (50 foot 5/8" OD Copper) carries hot water, heated by the water reservoir directly to your hot water heater. We show you how! No separate heat exchanger is needed!! This saves you $200.00 

Pump runs on demand NOT 24 hours a day like others! 

Again, this is potable (drinkable) water.


Insulated with R11 vinyl backed fiberglass! That's typical of a  house wall.

DOUBLE INSULATED (R21) ON TOP. You cannot feel the heat when you touch the siding!

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

The ash pan (non-removable) is 16" wide x 34" long and is 8" deep. It is easily cleaned at the front through the door with a small shovel.

Some other makers don't even have an ash pan! You have to shove the hot burning wood aside (or let it die) to clean it out!!

Water surrounds 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 heat - is trapped so that it doesn't quickly escape out the flue. That would be a big loss of efficiency. This is also a better idea since you don't have baffles getting a creosote buildup on them.

This also creates a 2nd 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!


170 gallon tank!

Many manufacturers only use 100-125 gallon tanks! The size is critical when heating a larger home. 

DON'T BELIEVE it when they say they can heat 4,000 sq. ft. and have 300,000 BTU. That's impossible without heating the water to over 300 degrees!

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

< 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 a manual draft opening.



Our furnace is so strong and well-made, that the chimney alone is strong enough to carry the 1600 lb. weight of the furnace!

Exterior is made of Heavy Duty Siding - 26 gauge Galvalume which has a 25 year limited warranty.

The chimney is made out of 1/4" wall, schedule 40 pipe and is surrounded by water. It tops out at about 6 feet above ground. You can EASILY add an extension.

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

Extra Large rear access door. All electrical items are in back, safely behind a door! 

Water and electrical hookups. 

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


ALL furnaces come with 2 hookups and 1 pump.
Extra pumps are $99

This is a great aid in getting a fire started, recovers the water temperature much quicker, and burns the wood up more completely.

Ash pan door and air blower inlet
 (seen in back)

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!

The air blows into the bottom of the fire, through the grate! That's better than blowing in from the front - into the side of the fire, as all others do.

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!


For one heat exchanger - 50 ft. from furnace

You will need one in and one return line per heat exchanger or hot water heater plus one run for the water fill.


Outside 3 x 50' = 150' Pex Pipe  $150.00
50' 12/3 wire 36.00
Installation kit includes all fittings, adapters, shut-off valves, etc. 77.00
PVC Pipe and Insulation for Pex pipe 115.00
Inside Heat Exchanger (100,000 Btu) 195.00
1-line Thermostat 19.80
25' 12/2 wire 20.00
110 V 20 Amp breaker 20.00

Sheet metal (Rarely needed, only if a heat exchanger won't fit your plenum) 31.00
4 hrs labor for duct work
(only if needed for heat exchanger to fit)
If heating domestic hot water add $99 for a pump and 50' of Pex at .89 a foot - for a total of 4 Pex lines. $145.00
Total: $632 - $929

Prices will vary depending on supplier and locale

Installation Kit

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 $140 each. Heat exchangers are about the $195 for 165,000 BTU (varies with size, many are less) and there are many being sold here on eBay!

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 yard for a 4'x10' pad (approx 4" thick), giving you a nice place to stand and load wood.

Shove the logs in on top of each other.

Use the poker for safety to push them in.

(That big pile of ashes may make the door seem low - but it isn't!)

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 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!



Thought there wasn't a fire?

Think again!

Within a couple of minutes - literally - 
this fire was roaring!




Great News! We can finally say that our furnace CAN burn coal, for sure.
We have had a customer (Pete) burning coal in his furnace this past winter!
He puts 8-10 shovels in, about to the bottom of the door, heaping in the middle. This little bit will last him 12-16 hours he said!
Pete said that one of the advantages of coal are that it heats up faster. He can come home late to a dead fire and the water cooled off (he's a truck driver) and can have heat in 20 minutes!
The coal also lasts longer than wood. Pete often mixes wood, putting it on top of the coal and it works VERY well, he said.
Pete is heating a 3300 sq. ft house and a 1000 sq ft garage with 12 foot ceilings - so an equivalent of 1500 sq. ft plus 3300 plus his hot water. 4800 sq. ft total.
The garage stays at 70 degrees even when it's below 0 outside!
To top it all off, his furnace is 325 feet from his house!! He's a happy camper...

We can build YOUR furnace in any of these exciting colors or any combination thereof!







We can also build your furnace so that you can apply regular siding,
brick, faux (cultered) stone or almost anything else.

We can also build them without siding and light.
for a savings of $230,
for those who want to put them in an outbuilding
or put another siding on it.




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 firebox is almost .400 inches thick as opposed to .200 in many furnaces. That's almost 1/2 inch!! They never rust through.

We just replaced a Hardy a week or so ago and there are many leaking Central Boilers and Hardys 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 34 years of experience.

Best regards,



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 34 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 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.



About us:

Shaver Furnace is a privately held company and was established in 1972. "

Shaver Heating and Air preceded it and dates back to 50. Gerald Shaver and his Dad 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 Shaver 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. Shaver furnace was indeed the first. The last revision was made in 1978
and the furnace remains unchanged, except for cosmetics, today. Now Gerald's son Billy
heads up the business.



We have been in business for 39 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
hundreds if not thousands of dollars at the same time.
