There are collectors on the roof heating water which heats a tank in the basement full of water which is then pumped through the floor. I use a more or less conventional wood stove as a cloudy weather backup both for the convection and to heat the water to pump through the floor. I've been doing this for about five years now and haven't blown up my house yet. This is because I'm not storing the hot water in the tank. As soon as the water in the tank heats up to about 100f the floor pump turns on and pushes the water through the floor, cooling it to about 75-80f. The floor will warm up to the upper 70's at most and it's just wonderful to walk around on barefoot in the winter.
I've recently been thinking of building a new house and using a rocket stove to heat it. Most installations I've seen discussed use the exhaust pipe to heat the thermal mass. If I wanted to replicate the hydronic radiant floor I have now, but use a rocket stove to heat it, what would be the best way to arrange that? I saw one example with copper pipe coiled around the outside of the barrel. I suppose that's better than inside, since the creosote that accumulates on the stainless steel water pipes inside my current wood stove is really gnarly.
Does anyone have suggestions or ideas?
Thanks,

RE: cool air being sucked upwards into the cavity as the air moves higher and into the open interior window.
What is the principle at play?
Thermo-convection I guess you'd say. The hot air wants to rise and expand, so it's happy to move into the high opening of the interior window.

In the case of no basement and no crawl room under my stumped house, I have pondered this concept before and now wonder the following....
Could I use a hole under the floor of the PASSIVE Solar heated room?
Or does there have to be a greater depth of the cold air draw?
Stumped, like up on legs? You could put a hole under the solar room, and it would still heat the incoming air from the floor. BUT this would only be practical for heating the outside air a few degrees. It would not effectively heat cold winter air and there would be no closed loop to promote flow and heat build.
Now if you ran a duct from the floor in the back of your house to the floor of the solar room, then you'd close the loop and generate heat and flow.

I have a two step drop /split level in my home.
The passive heated sun room is on the higher side of the split level lower room.
I wonder... is there any reason I could not successfully somehow make this happen, after navigating the no crawl room understory for the 5meters between the origins of the drawing cold in and the entry to the passive heated sun room?
The draw level difference would only be 1 ft or does that not matter?
I'm having trouble visualizing the details of this, but as long as you give cold air a path from a low spot in the house into the bottom of the solar room and out the top then you should get some flow.

I'm a bit surprised at how closely he planted his trees in the barn greenhouse. Maybe they're columnar dwarf trees (if that's even a thing).

Dan Hampleman wrote:Has anyone considered running copper pipes threw the heat storage or the cob and then to a storage/expansion tank? I'm wondering if you would always have to have water flowing threw the pipes and what to do to keep it from getting too hot. Another thing I'm dreaming of is having the rest of the floor made out of cob and the PEX tubing running threw that. You could have a separate water pump for each zone or even pump the hot water out to your greenhouse using hot water PVC.

My only worry is that I live in Louisiana. But... I don't live in a swamp or in a place that floods. I do have creeks & rivers nearby, but I live on a huge hill that has pretty good drainage. There are a few spots in my yard that tend to puddle up a little but nothing major.
So my question is this, does anyone have any tips for building with cob in Louisiana? I can't seem to find any info anywhere on building with cob in LA. No workshop nearby, etc.
