We will be installing the radiant tubing in the 1st floor joist bays in a few weeks using heat transfer plates and R19 fiberglass insulation below (pushed loosely up against the plates.) I have designed the tubing layout with 8 loops, approximately 195-205' each. LoopCAD seems to calculate an output of 13,400 BTU/Hr 100° supply temp and 1.5 GPM (for a 20° delta.) In the basement slab, we have 4 loops of 1/2" pex (250', 250', 230' and 230') laid on top of ~2 1/2" Creatherm insulation panels (R10 according to spec sheet).
#Can loopcad do a piping diagram manual#
I am unsure whether I should pipe the boiler direct, or with P/S piping.The boiler manual shows it being piped in either fashion, but I am not sure that my flowrates support this (or that it would be the best way to go considering we may add fintube in the future.)
I have been researching everything and seem to have narrowed down my design to use an HTP UFT-80W boiler and a SSP-40 indirect HW tank for DHW. We are utilizing in-floor radiant to heat the building (with provisions for adding a low temp fin tube loop to the 2nd floor loft if needed.) The building will have a wood stove in it for supplemental heat, but I don't want to factor that into the design and be forced to use it. I am currently building a cabin in NY near the Adirondacks.
Feel free to skip to the bold part for my actual question. Hey guys, I am going to apologize in advance for the long post, but I know people hate when threads don't include enough information.
