Ok, to start with, i know Im trying something that has been BEAT TO DEATH !!, but I'm stuborn I guess. LOL
So I want to "build" a wood fired heater for my 27' round AGB. I live outside any incorporated area, in New Brunswick Canada, so my pool season is way to short! My closest neighbor is 1500 meters away ( and it's my wife’s parents ), other then that it's just me!
My plans are to take a "barrel stove" http://www.vogelzang.com/images/BK150ELRG.gif , and wrap it in 1" soft copper tubing from front to back, input going in on the bottom of a wrap at the front, and ending at the back of the barrel on the top (hoping this will help with the natural movement of hot water). I also plan on wrapping the entire contraption (barrel & pipe) with aluminum insulation, and have considered placing the entire stove in a wood furnace case I have that has had the firebox removed, putting a pitched cover on it and possibly filling the entire case in sand, to aid in heat transfer to the copper first then the water. I know the risks of a "closed" system and a steam explosion, but if this is run with a separate pump, intake and output to the pool, so NO ball valves to accidently create a "closed system", in my mind there is no way to trap the boiling water and steam.
Now this is in its preliminary stages, I am FAR from a engineer, I am actually a paramedic by trade, so I am looking for all you pessimists to tell me why this wont work. I have a few concerns of my own..... A.) will it even make a difference? My original plans were to put the coil INSIDE the fire box, but after further consideration, thought the exterior heat sink might work better. B.) is it dangerous? C.) if it works is there anyway to safely attach it to my existing pump system with a simple bypass valve?
Any comments would be welcomed
