These units are Mitsubishi mini-split heat pumps. They are very efficient and can run in temperatures down to -20 deg. F without a electric back-up strip. They are great in heat and cool modes. The major benefit is you can connect up to three indoor units to one outdoor condenser. This provides flexibility with differing indoor temperatures. Hope this answers your questions. Thanks for the post.
Radiant heat (low mass). While concrete floors have historically been used for radiant heat because of their high mass, it does take a great deal of energy to bring them up to temperature. Low-mass radiant floors, such as the one seen here, are an efficient alternative. Combining the subfloor and radiant system in one structural panel and facing it with an aluminum skin distributes the heat evenly beneath the finished floor. A low-mass radiant floor comes up to temperature quickly using a lower water temperature than its high-mass or staple-up counterparts. As you’d expect, the panels are more expensive than a traditional subfloor, but the labor savings on the heating side help offset this.
