Heating Edge™ perimeter heating equipment is available for residential, commercial, and institutional applications, and is available in three styles — oval (HE1), perforated (HE2), and slotted (HE3). It comes with a patented coil and fin design. These components are mechanically bonded together to form a coil block, which retains convective airflow patterns as it enhances output by providing a radiant surface, the company says. According to the manufacturer, the Heating Edge’s twin pipe design enables the installer to choose a variety of piping methods, including supply and return, parallel supply, or using either tube as a single supply.
