Should I “Re-do” a Radiantec system
Recently installed a system I bought through Radiantec in a 32x40x12 pole Building. They did a heat calc. I have two insulated 10x10 doors. An 8x8 insulated. Two windows and, a Man door. R19 walls, R25 ceiling with steel ceiling and walls. 2 in foam under slab and 2 in foam on exterior of the slab (except where garage doors are) They sold me on a American standard 160,000 btu tankless hot water heater based on 96% efficiency. Ups26-99fc Circe pump getting 3gpm. 4 loops at 300 ft (two maybe a few feet shorter) I have spent hours reading on here after I already bought their system that I should not be using a tankless heater but a boiler. I like everything, it heats great but seems to be using a lot of propane. Around 20 gallons a week @ 55degree floor temp. Is that high or is that normal? That’s around $200 a month. Should I replumb for primary/secondary before buying a boiler? Mixing valve? Recommendations on a boiler? Supply temp is 100 degrees and return is 69 degrees. I live in northeast Ohio. Any input would be greatly appreciated
