sorry for the double post, but I just realized I should have posted here; admins may delete the original on the main wall
Hello all, it's me again.
I know some of you are probably tired of hearing about my intentions instead of actions, but I am just about to do the install. I have designed my hopeful setup in a 3D modeling software to help me better visualize how it will all be put together and assist with assembly. I have uploaded a video of an overview of the setup (seen here) and added a few of the screen caps to this post, also see this link for better resolution. Due to tight quarters, I had to make the most of what I had and hopefully you friendly and knowledgeable folks can point out a few easier or more efficient way to do this. For clarity, the copper/pink is all 1" copper line, while the blue is either 3/4 or 1/2". Since Burnham supplies the boiler loop pump, I am really only waiting on the sizing of the pump for the HWH and the system pump, but they're very close in physical sizing that I could mock them up in my model. Here's a link to the higher resolution mockups and plans here.
Refresher: replacing oil-fired combi boiler, cast iron recessed rads on main living floor, cast iron bases in basement, currently all on one zone, combined single loop. Installing new Burnham Alpine 080 w/50gal indirect. Currently setup for single zone, I will be adding the indirect tank and eventually another zone or 2. Roughly 72K heat loss calc, with poor shell criteria (slider windows, poor insulation in attic, etc.), hopeful to fix that over time. Northeastern NJ, see floor plans also attached.
I have followed Burnham's "Near Boiler Piping - Heating Plus Indirect Water Heater" schematic from the Alpine manual, and I think I have all of their specified components included in my mockup. In a previous thread, I had used an example that an HVAC specialist and shown me, but using @BadgerBoilerMN's criticism of overpumping, I decided to go with a system circulator with zone valves as opposed to pumps for each zone (especially since I currently will only have a single zone). I've shown a few Webstone flanges and other Webstone valves since I'm tight on space; while they're not price friendly, they do save me on valuable space.
As always, your comments and criticisms are welcome.
