What is Cozy Heat and what are its two variants?

Cozy Heat is Heatizon’s line-voltage electric radiant heating cable for interior floor warming, space heating, and slab heating — available in two configurations. The MI (mineral-insulated) fixed-length variant uses a central copper conductor surrounded by fiberglass insulation compressed inside a copper outer tube with an HDPE jacket, factory-terminated with pre-connected cold leads at both ends. The self-regulating cut-to-length variant automatically adjusts its heat output based on ambient temperature and is cut to length on site. Both variants are ETL listed and operate at line voltage — no step-down transformer required.
