RMH Project in NE Wyoming  RSS feed

Hi,

I'm a rank newbie and I'm starting my own RMH project in my home and have a question to ask:

Is rock veneer (basically painted concrete) a safe bet to use as a heat shield around the RMH's heat riser?


Of course, I won't be putting this inside until after it's made outdoors. Winter is closing in and I want my home to be ready for it. I plan on posting pictures soon as I gather materials. I have the the new videos for wood stoves (great information), the RMH book, and Mr. Wheaton's stuff. I respectfully solicit advice.

Thanks,
Dave

Dave Grim : I re-read this a couple of times and am confused so you get two answers ! If you are talking about attaching something to the walls inside your home to protect the
exposures from radiated heat then I am going to send you to another site ! I want you to hear and see the application from E + Es mouths

Presently, I have to send you to www.youtube.com/villagevideoorg This will give you an idea of how to protect your exposures. I don't like you-tube and rarely recommend going
there for information - A word to the Wise !

If you were simply asking about how to do the finish work on Your R.M.H., then I can promise that you can use anything. Compare the weight of a couple of Rook Veneer pieces
to the weight of a brick The heavier one will hold more heat and radiate it faster, at a Higher Temperature than the lighter one ! Hope this helps ! for the Good of the Craft !

Think like fire, flow like a gas, Don't be the Marshmallow ! As always your questions and comments are Solicited and are Welcome PYRO - Logically BIG AL

Dave,

If you are specifically referring to the heat riser, you want to insulate it because combustion is still taking place inside of it.

Concrete will burn up eventually if subjected to 400 deg continuously.

As far as storing heat, some materials are better than others not related to their weight. Our blog has a chart of the most usual options with notes as to the heat limit. Its under Reference on the blog. Here is the URL: http://blog.dragonheaters.com/category/reference/thermal-mass/

My mistake, I was talking about cladding the walls around the heat riser with a rock veneer. However, Mr Lumley's advice about using real brick or stone has me leaning that way. I have an 8' ceiling and a carpet floor I am going to be ripping out in favor of a future hardwood floor. I'm building my RMH on a suspended wood floor but I'm in the midst of a scramble to do so as winter is fast approaching 'round here.

I don't spend a great deal of time at my home because work is three hour's drive away. My main concern is making sure I have a better heat source than the last winter as I have a disabled family member living in my home and his capabilities are greatly reduced. I'm juggling this amongst other delayed projects that are also of importance.

Many thanks,
Dave

Dave Grim : Mr Lumley, was my father, a member of the 'greatest generation' that survived a depression, fought a world war (2) and came home to raise two generations
who had No idea what the old duffer had done to attempt to promote a De-mock-racy where celebrating will of the public was the primary way to serve !

My generation turned into the sound-bit generation, that had not a clue but marched to the polling box even as polling numbers went strongly against the vote of the
Elect ! Since then things have ' 'went to hell in a hand basket !' '

My best advice is still the same, watch the videos, building over/on a wood floor starts with bracing the floor from below, guarding against radiant (heat ) energy leaking
through the bottom of the rocket mass heater, R.M.H., and protecting your exposures, while you can off-set the barrel (a little ) to protect exposures, this is a crutch
that does not replace careful siting of the feed tube and the barrel relative to any exposures, and should be related to the shape of the ENTIRE TRANSITIONAL AREA !

You have actually described the worst possible use of a R.M.H.. What a proud owner of a 'rocket' faces (at some time) every day is a requirement to start the fire up from
scratch, keep this fire going, working in a minute by minute manner for as long as 1 hour, then some time- within that hour, or hour and 1/2- the internal fire turns into a fire
that has a combusion chamber glowing red hot that can be tended by ear - with frequent feedings, a piece of wood bursts into flame as it is fed through the feed tube !
Following these easy steps with a further 6-8 hrs should generate 20 - 25 hours of stored heat within the thermal mass for later total home heating ! Any thing else
related to cold weather is a fable and not related to actual performance in 'cold weather' ! I hope this helps, for the good of the crafts/permies !

Dave see the E + E DVD on Building over a Wooden floor. If it's dark, pick it up, if its heavy stick it in ! A. L.
