Outdoor Wood Furnace

A Unique Way to Heat Your Home

An outdoor wood furnace is an intriguing way to heat your home with wood without all of the bugs, smoke and trash in your home along with the smell!  All of our outside wood boilers will burn both wood and coal because we have a draft inducer blower, feeding air (oxygen) in from the back and up through the grates, just like a blacksmith's forge.  This is the only way that coal will burn which is why so many wood furnace manufacturers don't say that they will be burn coal.  Not only will they burn coal, they also have cast iron grates that will not burn out with the high heat produced by coal or wood species such as hickory, locust, orange wood.


Huge Savings in Fuel Costs
CUT-COSTS with an outside wood furnace

There are big savings that can be achieved in the cost of heating your home because you can use wood that has been felled or even fallen naturally or become ill due to disease.  All of this is free fuel as opposed to the high cost of electricity, propane, fuel oil or most any other fuel source.  

All it is going to cost you to heat your home is time, sweat and the minute amount of gas that you put in your chainsaw.  You can get away without cutting any wood by buying wood from a local firewood supplier but the cost of the wood will be much less than their normal cost for split and stacked firewood.  All of our boilers burn whole logs and no splitting of the wood is needed as with a fireplace or indoor woodstove.  Another big savings is the amount of time you spend loading a wood stove because our boilers and even our waterless furnaces take very long pieces of wood instead of the normally short, 16 inch split pieces that most indoor woodstoves require PLUS waking up every 6 hours to load your wood stove.  Getting a good night's sleep is virtually impossible when you have to get up at 3AM because you are getting cold!  

Many people seem to gravitate to a central boiler outdoor wood furnace but that is only because of their full-page color ads in every magazine. Guess who pays for that? YOU! THAT is not cutting costs!

 

Loading Your Outside Wood Furnace Once a Day

Yes, It is possible and very doable to load your furnace or boiler just once a day, even with out smaller front loading boilers. 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!"

When I purchased my wood boiler, I bought one that was big enough that I wouldn't have to load it twice a day, which is the norm in the industry.  Many of our furnaces, are only $300-$900 more for a bigger model which will often enable you to load it just once a day.  Going out in a snowstorm or blizzard or even cold blowing wind just once a day, is a pleasure compared to facing the miserable weather twice a day.

Enough BTO output to fill up as little as ONCE a WEEK!

Our top loading boilers will do even better stretching load times to once every 2-3 days or even once a week, depending on what you are heating and buying the right size of furnace.

You Want an Wood Boiler That is Simple

Everyone wants simplicity in their lives and that means no electronics, no computerized parts and no gadgets that are not needed, such as smart-phone monitoring.  

NO SMART PHONE for your wood boiler!

Who needs that when you are just feet away from your boiler or outdoor wood furnace because it can be just outside your door, as close as 5 feet to your building even if it has flammable siding - according to Underwriter Laboratories.  You can also have your wood furnace outside next to your wood pile or out of sight in the trees or behind a barn. 

These wood boilers can typically be 250 feet away from your home.  They can be farther away buy you are typically limited by the amount of insulated underground Pex Pipe that you can buy that is not spliced together.

Wood Boiler Pex Pipe is flexible!

All of our wood furnaces have off-the-shelf parts that are available anywhere and everywhere; locally at plumbing supply houses or often for less money on eBay.  There are no standard parts on our outdoor boilers that are more than $99 purchased from us.  The only thing that might cost more would be if you chose to upgrade your pump to a bigger model because of the distance you are putting your wood furnace away from your home.

 

What Do You Do With Your Ashes?

With the HyproTherm wood furnace you never have to worry about having to open your firebox loading door to clean out your ashes.  Why do I say that?  Most manufacturers tell you to open your door and to push the burning wood to one side in order to scoop out your ashes.  What they don't tell you is that your firebox is going to anywhere from 800F-2000F and you aren't going to get anywhere near it until you leave your door open long enough for the firebox to cool down and there can't be any burning wood in there which many of them make you think you can have.

Outdoor Wood Furnace Ash Pan

In fact, most outdoor wood furnace manufacturers don't even have grates in their furnace to enable you to clean out the ashes easily, much less an easy to remove ash tray which you will find on all HyproTherm units.  I empty the ashes out my wood boiler just once a month at the most because we have such a good hot fire that completely burns all the wood, unlike other models with just a draft door (like a Central Boiler).  The biggest complaint I hear about Central Boiler, other than their pointless warranty, is the fact that there is always unburnt wood left over.

Last But Not Least when looking at an Outdoor Wood Boiler

The most important quality in an outside wood boiler is the thickness of the firebox.  Many fireboxes are as thin as 1/16 inch.  Picture a 1/8 inch drill bit (pretty small) and imagine just half of that as the thickness of your firebox.  This is what most every manufacturer that uses stainless steel employs.  This is because stainless steel is so expensive (but still corrodes even if it technically doesn't rust) they have to make the firebox thin to keep down costs.  They even have warning labels on these furnaces to warn you against throwing wood in the firebox because it might damage it!  

We have replaced many stainless steel boilers from other manufacturers (Hardy, Crown Royal, Heatmaster, Fire Chief and Heatmor, etc that have totally failed within 5-6 years because of cracking that occurs in stainless steel due to the extreme heat.  Every metal gets surface cracks in it but when you have metal that is a mere 1/16 inch thin, the cracks end up going all the way through to the firebox and the next thing you know, you have water rushing in and killing the fire.

Stainless Steel firebox stress cracksin a boiler

The thickness of our wood boilers is a minimum 3/8 inch thick which is SIX TIMES THICKER than stainless steel.  We have an optional 1/2 inch thick firebox that is eight times thicker!  Not only that, we are the only manufacturer in the WORLD that builds their boiler with a water jacket bottom that is the exact same thickness as the firebox - be it 3/8 or 1/2 inch thick!

We even have stout used outdoor wood boilers WITH a WARRANTY! Who else does that!!


What is the heating capability (sq. ft.) of a wood furnace?
