So in you system how did you heat the water? Did it just reach 100°F by being in the greenhouse? Or was there some sort of heater?
I was heating with wood with an experimental wood heater. Its an interesting heater though it destroyed itself from to much internal heat. I have a build thread but I have not yet updated it with the tear down.

Its posted here if you want to check it out. I post on that site as gadget;

I'm building a new design this fall thats not as intense but its not for the greenhouse. I ended up switching over my greenhouse to a geo heater using 52F well water to keep it just above freezing. To much heat loss to do much more then that.
