<p>I have been enjoying lurking around this discussion immensely.</p>
<p>I started designing wood gasification stoves back in the 70's because I couldn't afford an Ashley which was the stove of that time. Basically the Ashley was a tin box but it had a bi-metallic coil thermostat and that made it way ahead of the curve, as it would shut down and control the burn on it's own which was a big safety factor.</p>

<p>I started reading everything I could get my hands on (oh for the internet back then) and came to realize that Ben Franklin was a wood burning genius with many patents that he gave to the world for free and most modern gasification wood stoves are based upon his work even though they never give him credit. Well I will and I designed my home made stoves based upon his work and I have sold plans all over the world. The Rocket stove is based upon the exact principles old Ben came up with. Once you understand those concepts you can have a ball designing your own stove and make it from cheap scrap items. My design heats the water as well as the air and holds a good 12 hrs of wood at one time.</p>
<p>Vlad made one from my plans and a slide show of my latest GH heater design and he loves it. He grasped the concept and made his from what he had available in Serbia as have others in GB and India, etc. Here are a couple of pics of mine and his and an interior shot of the gas burner chamber as well as the ss water coil in mine:<a target="_self" href="http://storage.ning.com/topology/rest/1.0/file/get/2772236683?profile=original"><img width="721" class="align-full" src="http://storage.ning.com/topology/rest/1.0/file/get/2772236683?profile=RESIZE_1024x1024" width="721"/></a><a target="_self" href="http://storage.ning.com/topology/rest/1.0/file/get/2772237155?profile=original"><img class="align-full" src="http://storage.ning.com/topology/rest/1.0/file/get/2772237155?profile=original" width="518"/></a></p>

<p>I now use a blower and thermostat rather than the bi-metallic coil t-stat of old. Works fantastic. My blower came out of an old dishwasher<a target="_self" href="http://storage.ning.com/topology/rest/1.0/file/get/2772230030?profile=original"><img class="align-full" src="http://storage.ning.com/topology/rest/1.0/file/get/2772230030?profile=original" width="640"/></a> and Vlad is using a hair dryer for now. I haven't done a write up on the GH heater yet but I can supply 60 still shots which are on Youtube under "fiskfarm" if you are interested in building one as well as my original set of plans on Ebay under "fiskfarm store" as well.</p>

<p>I'm also going to use a solar air and water heater this winter. Since I have a low polytunnel, I can possibly get about as many BTUs from my solar heater as I get in solar gain to the greenhouse itself. I look forward to posting my results.</p>

<p>Sorry Matthew, but I have to disagree with using compost heat for the following reasons: 1) Even though it produces heat, it's not a high density heat. If you try to heat a greenhouse with something that's only 160, it will quickly loose its thermal mass of heat... Those little bacteria just can't keep up with the demand. 2) You need a LOT of compost to keep up with the heating, I would rather use that space to grow plants. 3) You can't regulate the heat (turn it on and off). If you have a warm spell, you'll have to vent the building. At least with a RMH, you can shut it down if there's going to warm up. 4) Compost invites fungus/bugs/mice/rats. I think it's best to keep the compost pile outside and away from the greenhouse.</p>
<p></p>
<p>I also feel the same about putting livestock in the building. They don't produce enough BTUs to heat a building, consume large amounts of food (hopefully scraps), and you increase the risk of having warm-blooded pathogens getting into your system.</p>
<p></p>

<p>I estimated that it would take hours feeding the stove in my greenhouse while I was NOT in my home feeding the woodstove and working on other projects.</p>
<p>I abandoned the idea of a rocket mass heater in the greenhouse: to much space devoted to mass, to much time to keep heat up and was hoping a creative idea would present itself. And it did, Rick Stillwagon has a non-electric pellet stove that is amazing. I think the cost is about a dollar a day and will only take a few minutes to feed the hopper. see it @ <a href="http://www.zephyrgreenhousesystems.com/pb/wp_9e4a4a4c/wp_9e4a4a4c.html">http://www.zephyrgreenhousesystems.com/pb/wp_9e4a4a4c/wp_9e4a4a4c.html</a></p>
<p>saves space and perhaps more important to me is the time it will save.</p>
<p>I love the rocket stove and think they have a place in the world. The RMH have a place, and I might build on in the house to heat living space yet I have not seen the practical use in an AP Controlled environment. I welcome any comments, disagreements and advice.</p>
