>>>>>Cal how would this be on a greenhouse???
granny <<<<<<<
Well, this would only be helpful for a closed in building or house...
Greenhouse does a pretty good job of heating up when there is sunlight. The big problem is to heat it when the sun isn’t shining - (When I was working in my tomato greenhouse, I would often work in tee shirt and shorts when there was snow on the ground...) The problem is to store that day heat for night. If you are trying to keep temps around 55 degrees at night, heat sink helps greatly - Water and rock or concrete hold quite a bit of heat. Water holds 1 btu per degree per pound. So if you are trying to maintain 55 degrees and heat the water to 140 degrees during the day, you have 55 degree spread, 8 pounds per gallon and 680 BTU per gallon that can be given up to heat the house at night. While this helps, it will not completely provide the heat needed within practical limits. I relied on propane but when the price shot way up on that a few years ago, started using a 2 barrel wood stove
If you push it a bit, you can get 400,000 btu an hour out of it. It kind of loafs along at 180,000 and will last all night enough for most any greenhouse - I used to have a Sotz kit stove and just this year I bought 2 Vogelzang double barrel kits and a single one with the stove plate top. Plenty for a 24 X 96 greenhouse. You would have to have 265 gallons of water at 140 degrees for each hour you wanted to heat - 12 hours = 3,176 gallons of water. Then some cloudy days and you are sunk...

I put the Sotz stove in the basement of a two story, 4 br 2 1/2 bath with attached garage house that I built - put a louvered door to the basement and put two cold air return vents on the North side under two windows. (I made the basement 13 blocks high as I hate low ceiling basements.) It worked great - floors were always toasty warm and it heated the whole house very handily - My Ex still uses it.(she had to change the barrels a couple of times over the past 25 years)
You would never guess that my college work was in Ag Engineering... LOL Only thing that was broad enough to contain my varied interests.... Civil, Structural, Electrical & Mechanical Engineering all rolled into one...

That and a strong back sounds good to me.
None of that is possible for me, I can’t even hire a man to patch the metal roof on the trailer, LOL, no way I would think of hiring one to build something.
No, I can’t handle any of that, as I pass out if I wave my arms around, not enough air left in my lungs for moving around much.
You set up does sound good.
