The BEST OUTDOOR WOOD FURNACE!

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.

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

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.

These 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 (4 bolts) to transfer heat to the door it does an excellent job of insulating the door.

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 door frame
will take a pounding as you throw them in!

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

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

Compare Firebox thickness to another popular furnace at only .200"
Ours is almost .400" ! 

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!

Only 3 welds to make the whole firebox - instead of 12 in a rectangular box!

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!

only minutes after reloading with wood!

Firebox size is 36" 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 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 

Again, this is potable (drinkable) water.

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

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!

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

Many furnaces don't even have an ash pan, so you have to let the fire die down or shove the burning wood aside to clean them 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 75-100 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 (less wasted wood) 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; the standard in the industry for water tanks) - 2 times thicker than many others using only 16 gauge.

< There is a 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 the 1600 lb. weight of the furnace!

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.

Having the blower in the back, feeding air/oxygen into the bottom of the fire, is a great aid in getting a fire started. The water temperature recovers much quicker, and burns the wood up more completely.

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 damper!

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.

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 on eBay though!

I can send you a link to those sellers.

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 $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. Most people can do at least 90% of the installation themselves.

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 and load wood.

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.

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!)

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!

We can build YOUR furnace in any of 20 exciting colors
or any combination thereof!

EXAMPLES:

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 for a savings of $200,
for those who want to put them in an outbuilding

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 .400 inches thick as opposed to .200 in many furnaces. The Heatmor furnace is only .102" thin. Ours is 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,

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 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 one of our competitors, you will be quite comfortable and enjoying your new cost effective Shaver's Hot Water Wood Furnace.
