Three years ago I purchased an outdoor wood boiler. It was a start up company out of Grand Rapids MI, and I'm now having regrets.
Could you tell us who that company was/is? I didn't realize there was one in GR besides the one that makes HUGE commercial type log boi... uh, I mean big ones! Being in Kalamazoo, I'm curious who is around this area.
To answer your question; Central Boiler makes a good unit. I dislike them myself, but that's because I'm an old, stuck in my ways welder and I don't like some of the things they do. That said, I have several friends who have them and love them. They've had no issues with them even tho one of them is pushing 20 years old. Portage and Main is an excellent unit too. Unfortunately, the rep in this area of Michigan is a ... well, he could be more attentive. Ridgewood is another good unit, made here in Michigan. I might have one of them if they made one big enough for my application. Heatmaster is also good, despite their use of stainless steel in the firebox. Again, it's that old welder thing!
I have a Hawken. So far, I like it. The main reasons I bought it were, 1) it was big enough, 2) it was ultra simple - no electronics, 3) I was able to meet the owners of the company and they answered ALL of my questions, (even tho it might not have been in their best interests on a couple of them), and they allowed me to have free run of their manufacturing facility for a couple hours talking to their employees and watch their processes, and finally, 4) if this thing ain't all they said it was, and they won't MAKE it all they said it was, I can take an hour trip and back it thru their front office window!
If I had it to do all over again, I might do a little business with one of the fine people right here on this forum!
