Hi all,

I will soon be detailing out my greenhouse. Inside the greenhouse I wish to 
have a back up heat source that both back up my domestic hot water with a 
heat exchanger and I would like to transfer heat preferably directly into 
either a water wall or earthen wall.
I have been thinking about the rocket stove and sending the exhaust pipe 
into the wall before heading outside. I am wondering if anyone knows of 
anyone who has put in a heat exchange loop in this type of similar 
situation. Or do you have a reccomendation of a commercial burner that might 
do the job? I am wondering if having a non-certified burner will exclude me 
from being able to get insurance? Anyone have to deal with this insurance 
issue yet?
