Hi Larry,

Cora's doing great.  11 months old now and crawling.  It's kind-of cool because now we know she wants to be around us since she could crawl out the door if she didn't .

I'll look forward to pics.

Havent been on here in awhile, how is the baby? (last time I was around he/she was due any day)

I finally got around to building the "greenhouse" on the south side of our brick house. ( house is solid brick construction with 14" thick  brick walls circa 1850s) Also the cistern ready for service. just now working on setting up the other tanks, grow beds, ect ect. I will take some pictures of what I have so far and see what you think.

I have a similar room to the one Rod has in his drawings on the west side of the "greenhouse" with double  brick construction (it was already there we just expanded farther past it) it also has a full cellar under it as well. somewhere in the 10' x12' size for both of those, and the total size of that room and the rest of the "greenhouse" came out to be 14' x 34'.

Hey Rod, I've been looking for a thermostat like the one you're using, but in Fahrenheit.  I ordered one of these and one of these, from the same person on eBay but both were not working on arrival.  Do you have somewhere you get them so they work?

No it's not in my house, its in the hall next to my breed tanks, and against the partition wall of the greenhouse, so it heats everything , block walls heat up and concrete floor, i have a fan pushing the air into the breeding tank room and intend to do the same for the greenhouse when its complete.  I'll upload a model i did of it, following the plan pretty tight.  if you look at the right side of the photo you can see a thin black wire... thats the temperature probe that i taped to the pex after the copper, and UNDER the fan... so it doesnt heat up from atmospheric, only water temp.  Since its on the cool side of the STC-1000, it kicks on when the water temp in the tubing hits 32C, and so the pump kicks on.  The fish love it, i just noticed that when it kicks on they scurry over to the exchanger at the bottom of the tank to get in the outflow like coeds to a hot tub LOL....  It does not run all night, but keeps up for about 4 hours, and since it heats all that mass of walls and floor, like last night i loaded it at 10pm and at 5 am the room was still at 60 degrees.  Next i intend to design and build a rocket heater with the same coil design, only put the coil INSIDE... and it should kick on a lot more and use less fuel.

Hi Rod,

Your setup is awesome!  I think Jim Fisk has something slightly similar, but I'm not totally sure.  

Is that the stove that you use to heat your house too? Will it heat well all night?

So it comes on when the water in the pipe is 32C?

Jeremiah thanks for the great forum!!  Really excited about it.  I started my operation a few months ago, dead of winter Panhandle Nebraska.  To save money and avoid power outage issues, I designed a wood stove heat exchange system thats working great heating 1,000 gallon tanks... just want to share, took a few tries to get it right, but basically I wired a STC-1000 controller using the cooling side relay, to a hydronic pump (recirculating/open) and run it through a matching copper coil inside the tank to keep from scalding fish.  It comes on at 32C and pumps til it cools down, then repeats.  Works phenomenal and only costs me a tiny amount of electric, and wood.
