thanks, yeah, my shop is too small as it is so this worked out nicely.  Plus I don't have to keep it burning full time.

I am not a boiler expert but I do know a lot about them and what works.  You have to get the boiler shutdown quickly but snuffing out all the air.  I have a flapper connect to a solenoid that is wired to the aquastat so if closes off the air to the blower so it doesn't keep feeding the fire.  I did a ton of research and put in a handmade 20 ft. steel coil that my return water runs through before dumping into my tank.  I burn over half of the amount of wood that I use to.  It acts as an on demand hot water heater and have it perfected to where I get super heat of approximately 70 degrees hotter than what the water enters at.  It's all about regulation, style, and length.  It is a true wood saver and know noone that does it.

I don't want to hijack this thread but could you provide some more details? Maybe some pics?
thanks,
dave

Home Made / My hot air outside unit

« on: October 09, 2012, 05:40:54 AM »

Hi all, I just wanted to share a few pics of the unit I put together a couple of years ago. It has been working like a charm. I have built a water loop to put in the firebox but haven't gotten around to installing it yet. Right now I only use it to heat my garage when I'm working in there. My goal is to install the loop and run it 40' to the house with insulated pex (I have that already) and through a modine which I scavenged off a demo job a few years back. I also have a Taco pump. It will be an open system with a small tank for storage. Anyway, on with the pics.

I'm no expert but won't that exhaust pipe running through the water that long cool the smoke too much and cause creosote build up and other problems?
Other than that I like it
