Established in 1980 as BioTherm Engineering, we created the first commercialized root zone heating (RZH) systems for commercial horticulture. BioTherm's legacy product, all-aluminum SunFin, was developed in the 1950s and is considered the gold standard (performance rated by AHRI) for institutional greenhouse heating. Our BioTherm MicroClimate system was introduced in 1980, followed by a constant string of durable heating solutions like StarFin, DuoFin, MegaTube, and GreenPex.
