Re: [papercreters] off topic???

so many responses sorry haven't replied.  I am still looking for plans but also pondering creating something on my own.  My friend is a union pipefitter and very creative so I am thinking about designing something myself.  The catalitic convertor thing is interesting am wondering if i can just steal one of a diesel pickup(guys cut them off to get more power should be able to get one for free) I am wondering if that is all you have to do is put the convertor in the smoke stack.  I have a 2 burning barrel wood heater for the garage(this is an old school kit that you can buy bottom barrel fire top barrel heat exchange) I am thinking of using this as the base of my unit.  Maybe suspend a water tank in the middle of the top barrel or run the water through the top barrel in a radiator or something.  I figure if I build a structure around it all and cover the inside and outside with papercrete it should be well insulated.  Keep the comments coming e very post helps me form some plan and heck somebody has got to have built one of these and posted plans

With that said, take a minute to look at the combo of cob bench and rocket stoves CobCottage.com is promoting.  If I weren't doing PAHS that's the way I'd be heading.  Very efficient, both in heat recovery and low emissions.

The above link gives emission comparisons for different type heating systems.

There are many commercial outdoor wood burning boilers available but they aren't cheap.

Hasha's were popular about 20 years ago but I haven't found a recent source.

If you want to build your own, the things to remember are a fast hot burn and complete heat recovery.  A forced air draft will give you the heat you need for the cleanest burn. 

HOWEVER

Your money would be best spent on insulation.  This brings us back to papercrete.

I have watched the post for a while now but really haven't posted. Now
I have a question. I know that this group has a varied group of
opinions. Outdoor woodburning boilers. I did a search this morning
hoping to get plans to make my own. Moneys tight and Michigan is
cold. I have not found plans but I have found lots of flaming by govt
organizations. I hate to be the doubting thomas but I can't help but
to believe that some if not all this flaming is indirectly from the
existing fuel industry. But it has raised several questions for me I
am hoping to get answered. Can these be built more effecient it seems
that oxygen starvation is how these units work(leading to smoke)? I
have read a longer chimney is better anybody have an idea on how tall?
Does anyone have plans or know where I can find them? I am genuinly
curious as to everyon es opinion, I personnally live in the country, I
have enough deadfall around my house to heat for years, and thanks to
Michigan icestorms always ad to my supply.
