Line voltage products like Heatizon lines of MI Cables, Heatwave floor warming mats, and Self Regulating Cables are fed by a typical 120V, 208V, 240V, 277V, 480V and in some cases for MI Cables up to 600V AC power.  These products are either constant wattage single conductor or dual conductor or dual conductor self regulating.  High voltage products do not require a transformer and are an economical solution for many projects.  Typical high voltage products offer a lower warranty than low voltage products and more expensive circuit breaker components for outdoor applications than low voltage systems.  Low voltage products use a step down transformer to convert high voltage to low voltage. These systems are very easy to repair compared to high voltage products while using a safe low voltage power source.  Low voltage systems offer a higher warranty than their line voltage counterparts.  Heatizon offers such a wide range of product choices because each and every one has an application where they fit best offering our customers a choice for the best product to fit their budget and application.
