The thing's a monster. This build was designed with efficiency in mind, but I question the lack of catalyst. It allows you to basically reburn the volatiles as a secondary fuel, instead of going up the stovepipe and condensing as solid creosote. If you stick a catalyst before the heat exchanger section you'll drastically reduce the creosote accumulation and you can get an extra 30% BTUs out of your firewood. For such an efficiency focused design I'm wondering why there's no provision for a catalyst. I think they might even be mandated in some areas now.

Just my 2 cents on this....he will have trouble with creosote build up in the chimney piping & smoke back drafting when the door is opened to add more wood. Removing too much heat from the chimney will be the cause. I have an almost identical build with 40" dia. x 5' long burner & heat exchanger with only 6 pipes & box fan removing the heat. I had to lessen the amount of heat removed & also added another 5' of insulated chimney to keep the draft upwards & the chimney hot enough to not have as much creosote build up and back draft.

I built a similar stove from a Sotz kit back in 1986. Lower chamber was a 30 gallon water heater tank and the top chamber a 30 gallon drum with a removable lid. I also had the Sotz catalyst kit between the two chambers. Heated my house with it for five years. I could load it up Friday morning and come back Sunday night and still have coals left over. I did put a refrigerator door on the wall to protect the wall from the stove's heat.

Take care, Carl.

Nice job! I would get into variable speed fan controls and or thermostats, they can be had fixed or variable. I had to slow the fans down as the air speed felt cool but it did make the garage temp required in my hot water system, just felt cold if you were working directly in front of the air path. Being a Toolmaker and not much HVAC at all so didn't really know what I was doing but fiddled around and got to where I wanted to be. I put an hour meter to tell run time so can keep track of performance

Hello Seb:
My brother-in-law had the sweetest solar set up: Big box of water ( 2 tonnes ) with two pumps. Pump 1 would pump the water to the solar collectors when they were hot, other wise they would drain so no freezing problems. Pump 2 would pump water to the floor pipes when the house thermostat asked for heat. The one thing I would add was an underwater Snorkel stove to heat the water on sunless days. I have a snorkel stove in my hot tub and it works great!

This is a picture where I was replacing a rotten end.
