BioTherm® StarFin’s™ tapered six-fin design has three times the surface area of two-fin designs or 51mm thin-wall steel tubing.

This increased surface area produces BioTherm StarFin’s high heat output, allowing lower water temperatures to be used while producing soft, gentle greenhouse heat.

High heat output cuts installation time and labor because fewer pipes are required to meet the heat load. Our large I.D. allows long loops with generous flow rates, resulting in greater evenness.
