StarFin™

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

BioTherm StarFin™ is our high heat output finned pipe commonly used for bench, perimeter, top, and gutter heating. Its tapered six-fin design provides maximum heat output while producing a soft, gentle heat.

StarFin’s large surface area decreases the amount of pipe needed, reducing shadowing, installation time, and labor.

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.

Additional information

StarFin™ can be used in the following applications:

Under-bench heating

Perimeter heating

Gutter/Snowmelt heating

12-foot sections are joined with O-ring fittings: no tools or welding required. New and improved StarFin features a ridged surface, increasing heat performance by up to 10.5%.

A heat source is required for this hydronic heating system.

How it Works

Aluminum Fin Pipes, like StarFin™, DuoFin™, and SunFin™, efficiently transfer heat by circulating warm water through the pipe system, with the aluminum fins providing an extended surface area to radiate heat into the greenhouse environment. This design ensures even and consistent heat distribution, optimizing the growing climate.

Why Aluminum Fin Pipes?

Our Aluminum Fin Pipes, like StarFin™, DuoFin™, and SunFin™, offer efficient, shadow-free heating with versatile applications for under-bench, perimeter, and gutter systems.

Superior Heat Efficiency

StarFin™ radiates significantly more heat than traditional steel heating pipes, thanks to its increased surface area, ensuring optimal greenhouse temperatures

Easy Installation

Requiring no welding, StarFin™ is lightweight and simple to install, saving time and labor compared to heavier steel systems

Enhanced Light Transmission

Unlike steel pipes, StarFin™ doesn’t cast shadows, maximizing natural light for plants and contributing to healthier growth
