Hi all, I found this great site via another site I frequent. I am an avid DIY'er and have an idea about putting a water loop inside the firebox on an outside hot air wood furnace to supplement heating my house. The wood furnace is 48' from the house, the firebox is aprox. 20" in diameter and 38" deep. I started with a Fawcette hot air wood furnace and built an insulated steel framed box around it and insulated it. I heat my detached garage with it but would like to help heat the house as long as I have it burning. Right now I only run it if I have a project in the garage.
My idea is this: I built a double loop of 3/4" black iron pipe, two 36" lengths and two 30" lengths, I used 2.5" nipples between the elbows, it sort of looks like a trombone...LOL.
I want to put this in the firebox up high and to the right as you open the door (I think it will be the most out of the way place for loading). Then plumb it underground to my basement where I will have a Modine (size is aprox. 12" x 12". I already have the Modine and the circulator (taco 007-f5) I am running 3/4" pex (insulated of course) to the house. One of my questions is should I install a small storage tank, say 30 gal.? or just run the loop as is , firebox loop, Modine and circ. There will be a TEE on the top of the firebox loop so it can be an open system, I will devise some sort of "tank" that will hold a little H2O/Glycol as a reservoir and escape route.
thanks,
dave
If anyone has any questions on my wood burner I will do my best to answer them.
Here are a couple of pics of my wood burner.
This is my second winter with it and it works way better than I ever thought it would.
