General Outdoor Furnace Discussion / Re: First boiler install

« on: October 18, 2017, 05:11:57 PM »

Thanks for the info/advice! I think I am slowly getting on track. I have a few more questions. I am looking to get a Grundfos 26-99. It will be about 70 feet from the boiler to the house. It seems that 1 1/4" is the proper size pipe? Do I have to keep everything 1 1/4" on the inside on the main loop? My plate exchanger for DHW would have to have 1 1/4" ports, right? I plan to go through the plate exchanger, then I also will have a 14x18 HX for my upstairs, and a manifold feeding eight 1/2" loops in my basement. Loops are less than 300'. Thanks!

General Outdoor Furnace Discussion / First boiler install

Hello all! Thanks for letting me in!  I just purchased a P&M BL 2840, and this looks like the place to be!  I have a lot of questions.  I was wondering if there was a page somewhere or sticky thread that describes best practices for plumbing things up.  I'm not doing anything too complicated--DHW, radiant basement slab, and HX for upstairs forced air.  I am thinking I will do this off of one loop from the boiler?  I'm just not sure what all components I should have, and how to configure them.  Any advice greatly appreciated!
