Well, it has been awhile since I posted. In fact, I couldn't find my original thread without searching under my previous posts. For some reason, it was removed from the list of posts on this forum?? Work on the boiler pretty much came to a halt as summer got here and I always found other things to do with my time. True to form, I am back to racing the clock to get this boiler done before winter gets here. I poured two 8" thick concrete slabs to set the boiler skids on and placed it where I wanted it to sit. I got the door figured out and finished (the latch is removed in the photos below) and painted it with high-temp paint. I insulated the door with fire bricks and expanded metal tacked over it. Time will tell if that helps keep the door from warping. I started welding together the frame to hang the sheet metal on a couple of days ago, and I'm a little disappointed that I didn't make the frame for the door deeper so that I could have left some room for firebox insulation. Instead, I have my doghouse frame sitting right up next to the front plate of the boiler. Live and learn I suppose. I had to leave clearance to be able to adjust my latch and hinges if/when the time arises to do so. I am doing basically a flat roof with a 1” per foot rise over the length of it (to shed water) because I didn’t want a roof peak with the chimney and vent pipe sticking out—I figured it would be too hard to fab up the frame and make it look right and be functional. I had the only local wood boiler guy I could find come out to quote me some prices for installing the duct coil and plate heat exchanger, but I think, after our conversation, that our philosophical differences on design are going to prevent him from doing the work. I am looking for someone to install what I want, not what they think I should have. An example of this is how his underground line-set he builds himself has one-piece pipe insulation around both pipes together, and shoved into corrugated pipe. No separation of the lines from one another, and he insisted that the largest lines he installs are 3/4” pex. I told him I wanted 1” true ID pipe, so I wanted 1” pex-al-pex at a minimum. He tried to convince me that he puts 5/8” lines in most of his installs and pushes 11 GPM through it. (I tried to not roll my eyes as he was explaining this to me.) I tried to tell him I wasn’t interested in going that route, but he insisted he had the experience to tell me what I needed. I guess I’ll continue looking for someone to do it the way I want it done. I can’t afford Logstor, so I contacted a foam contractor about foaming in the trench and foaming the boiler water jacket. The price I was quoted was $800 to do the job. Still not sure what I’m going to do about this yet. He also told me that a 5x12” 20 plate was way overkill for my domestic water. He wanted to install a 3x8” 10 plate, even though I told him I was running it in series to my duct coil and didn’t want to obstruct flow. I guess I’m just a little frustrated and needed to vent some. Sorry to ramble so long. On to the pictures:
