Burning wood in a Harmon Mark II

Burning wood in a Harmon Mark II

PostBy: jotuler On: Sun Aug 23, 2009 8:01 am

I live in NY and tornados are rare, but the end of July brought an F2 tornado through my property ripping out (by the roots) a number of very large (150+ years) oaks, 2 large maples and a number of ash trees. Luckily, my house was spared any major damage (I guess I'm a better carpender than I thought, either that or it simply missed. I like to thing the former). I am however, now the proud owner of 200+ tons of burnable wood. The question is can I burn this wood in a Harmon Mark II, and what modifications do I have to make to the stove, pipes, damper etc.?
Any discussion would be helpful. Thanks

Just trying to lemonade out of oak leaves.

P.S. Some good fortune; a large number of poison sumac trees were spared. :roll:

You can burn wood in the Mark series stoves, just remember that creosote will build up in the chimney and pipes. Later on the first nice hot coal fire may result in more heat then you expected!

Thanks Wood'ncoal
I understand that I have to remove or cap my barometric damper (I just read that on another thread) but what about the fixed air vent in the door? Do I have to block that or leave it open?

Yes, cover the damper with foil, wood fires need more draft.

Leave the openings around the glass alone, wood needs overfire air. The only negative about burning wood in a Mark stove is the lack of overfire air vents, that will effect the performance somewhat. That said I will say I don't burn wood in mine, only do so when lighting a coal fire. After burning wood as a primary heat source for a long time I'd rather have a coal fire. I do still have a wood-burner in the fireplace, though.

Sell the wood...
Buy coal with the profits.
Build a wood gasifier...
Sell the electricity...
Buy coal...

I did not like the results when I burned wood in my MarkII...
The glass sooted up...
As was mentioned no over fire air intake...
Besides cracking open the door a bit!
The VC Vigilant now that burned the wood nice...
But it was designed as a wood burner!
Use the correct tool for the job.
If you want to burn wood a dedicated wood burner is in order...
But I would always try to find a way to burn coal...
So much easier...
Even in a hand fired...
I just upgraded the Mark II to a DS Machine Basement #4 New Style Champion.

That does have over fire air...
So I may light an occasional wood fire in the spring and fall...

Sell the wood...
Buy Coal

CapeCoal makes a good point. Around here at least wood is bringing premium prices. I'd cut & split the wood & sell it.

Funny how things change.... 3 or 4 years ago I'd never given thought to selling the wood, but now that I've burned some coal....well... selling the wood and buying coal will give you more BTU's with less work. Simple as that.

The firewood business is competing with all the other wood based business...
The wood pellet makers have large volume requirements...
They have used most of the waste sources up...
The lumber mills have slowed a bit...
So the pellet makers start using logs...
The same logs that firewood is made from...
Price of all wood goes up...
Including firewood...
Sell the wood as is...
Or process it into firewood for more value if you have the ability and time...

The rise in the cost of firewood plus the questionable quality I was getting is what "lit" the interest in coal in my mind. I never looked back.

I probably will have to buy a cord or 2 soon for the Fisher, I bought none last year, 2 cords the year before.

Before coal I was burning 6 to 8 cords per winter plus using the oil burner. Needless to say my hillbilly wood guy wasn't too happy...

Sell the wood and buy coal. A check of wood burning websites will convince you that burning wood has far more disadvantages then advantages. That “free” wood is going to cost you in time and energy just to produce an unsatisfactory level of heat. I say that because I believe you will never be satisfied with wood after enjoying the benefits of coal. At its best wood burning is labor intensive and dirty. Just storing that much wood so it doesn’t go bad is going to be space prohibitive. Sell the wood up front, buy coal and be happy! Lisa

Maybe you can even sell it to a mill so they can make planking out of it, if not sell it as is. I am not a fan of doing wood if i dont have too.

This is a great idea. I know a guy who is always on the look out for hardwood trees which he can have milled into planking for cabinets and different pieces of furniture. He pays top money and hires the folks to come get it off your property. Maybe there is such a guy in your neck of the woods. Lisa

I sell log lengths to a buddy with a sawmill on occasion. You will get at least twice what it would be worth as firewood and it saves the cutting and splitting work for you. Don't drag the logs in the dirt though, he won't want them if the bark is loaded up with dirt. It will eat the teeth on his saw.
