I am in the rough in stages of having our new home built. It is a 2 story with full basement. We've opted for the Hi-Velocity system. In order to keep the basement enjoyable, we chose to go with a small HV-50 fancoil supplying 23,200 BTU @ 110F supply (20,000 requirement) and a HV-70 fancoil supplying 55,000 BTU @ 150F supply (50,000 requirement) for the 2nd/main floors.
My question is these fancoils can be supplied between 110F and 200F based on the BTU output you require. What kind of comfort is compromised throughout this range? I am suspecting that 110F over the coil is going to feel alot less hot than 200F over the coil. I would also suspect that 200F supply would create a hot supply surge to the home under call for heat and a lesser temp would be a more subtle heat supply which to me would seem more comfortable and favourable.
Does anyone have experience with the various temperatures?
