First I'd like to thank you all for educating me on wood boilers. While I bought a Seton W-90 three years ago, I'm just now getting to the "fun" part. Learning how to fire this little girl. The folks at Bethel Engineering thought this boiler was too large for my house, but when I suggested a 500 gal. storage tank they consented to taking my money. I thought, "that's a switch". I've built a 12' X 24 ' shed atop a concrete pad. I set the tank and boiler and started the piping. As I threaded the 1" schedule 80 by hand, I told my wife "this is apprentice work, how bout a hand". You can imagine the response. It was just starting to get cold last winter when I finished the boiler. This spring I repiped the propane unit in the house to tie in the Seton. After 4 days of firing, I think I like it. I'll try to post some pictures a little later.
