    30 years and counting

Good topic! I have been heating with wood in Minnesota for about 30 years but the last 7 years are the only years we cut the wood ourselves when we bought a farm.

The farm house presently has a Blaze King 100,000btu in the basement, a Sheffield Lopi and a Vermont Casting Defiant. It's a 1,800 sqFt house and to keep up heating the place in -35 F temps is a lesson in futility. I go through about 6 cords (not truck loads) a year but could easily burn twice that to keep the place toasty.

After studying Rocket Mass Heater Designs, I have decided to remove the present stoves (they are for sale if anyone is interested). As pretty as they are, I am all jazzed about getting more heat from less wood concept and have collected all the parts I need for the RMH, except the refractory cement.

Anyone else leaning toward RMH? I

 Also see people are including Peltier Modules for electrical generation in their Woodstove and RMH designs so- any other forward thinkers here doing similar stuff?

    Considering It

I have been considering going that way as well MBA,

We have been heating with wood for over 7 years, but I cheat by having one of our local loggers bring us two truck loads every so many years.  I go through two truckloads in about three Winters or so.  Depends on the Winter.  This year I didn't have enough cut, split and stacked wood.  So I've been working outside cutting and splitting add'l wood since January.  Of course, that does mean I have lost some of my Winter weight, which my better half and doctor were happy with.  Pros and Cons.  But I digress.

I've consider both the rocket stove and the Russian/Swedish Stove designs in lieu of our current Hearthstone wood stove in the family room.  The lure of less wood with more heat over time is quite attractive to me.  Not so much to the wife, but she isn't one working outside in the weather and let's face it; this Winter was colder than most in the past decade.

My wife doesn't like the thought of having a 55 gal drum in the family room, so the Russian Stove is probably the way to go.  I have no problem working with refractory and other clay in building that beast.  We are lucky in that we have a central chimney with two flu's for wood burning stoves that I can leverage for both heating and cooking.  My brother-in-law is a mason so he'll probably work with me on the build after I put together the design.  That chimney I mentioned runs right past the upstairs bathroom.  We capture heat from the chimney brick to heat the bathroom during Fall, Winter, and Spring.  It works great!  We just created a 'window' in the wall to allow the heat fo flow into the bathroom and trimmed it out and painted it white.  The bathroom averages 65 F to 70 F depending on the weather outside..

For what it's worth, our home dates back to the early 1800s, has terrible wall insulation (working on it) and is approx 2000 sq ft.

I like the way you think…  😉

    Rocket conversion

Heating with wood for 15 years now. Cooking for 2 years. Both wood burner and range cooker have a batch rocket conversion. Results in a very clean burn. Noisy though. I have never swept both chimneys, but they do get an annual inspection. Note that I only use very dry wood.

We still have central heating for the bathroom, waterbed and domestic hot water. I hope to have the water also heated on wood next winter, so the central heating can function as a backup.

Annual wood consumption about 10 m3. Small living quarters.

A hint when building a RMH indoors: do not use the common open fire chamber. Smoke, or worse: carbonmonoxide can blow back. Better to build the so called batch rocket. On this forum it can be found: http://donkey32.proboards.com/

Regards, DJ

    Good to know

Thanks for the input. 

This farmhouse is also build 1800s on one section, 1930'ish on another and 1970 addition. 

Insulation has been an ongoing project and windows aren't in the budget.

i agree with your wife on the appearance of a barrel in my media room so it's gotta be hidden as well as accessible. 

The final stages of the RMH are to use Peltier pieces for some small electrical generation to move the heat around. I'll keep posting the progress and the results on the first one to go in.

    Anticipation…

I can't wait MyBackAchers!

We already did the windows and the French Doors leading to the back deck.  The insulation and siding are now in progress as we get the best return from good insulation and Tyvek as a barrier.  The attic insulation was put in first as that was pretty lame (about 6" deep as I recall).  We had some areas where wind would penetrate the house from under the front porch.  I addressed those this past Summer with spray-in foam and fiberglass batts/flexible foam for some of the cracks.  I should probably have created a blog just to walk all the flipping repair I've made over the past decades.

I really wish you well on the RMH.  That should solve a lot of heat issues.  I warned the wife, 'One more Winter like this and I am putting in that Russian/Swedish Stove.  I really want to capture all that heat!

This coming Summer I am putting in one or two solar batch heaters so that I can use them in the other three seasons for hot water pre-heating and even hot water if they are efficient enough.  

Cheers!!

    Comes in 3s!

The chances are high we have more winters like this as the Old Wives Tale says:

Three years Hot then Three Years Cold –Three Years Wet and Three Years Dry.

its more like a total of 6.75 years according to old farmers, but we can expect a few more cold ones, which just followed 3 hot n dry years.

What gets me is everyone talks about Climate Change and I think I am in agreement that the extremes are tending to get more extreme, but then it could just be me getting older.

    Rocket Conversion Help?

Hi DJ,

We are interested in converting a beautiful old-style wood burning cookstove so that it uses a rocket instead of a smokey traditonal fire.  Can you share how you converted your cooker with us?

Thank you!

Elsur
