EasyHeat SR Self Regulating Heater Cable

EasyHeat SR Self Regulating Heater Cable

EasyHeat SR trace heating cables are used in frost protection and de-icing applications to prevent costly damage to residential and commercial guttering and roofs.

This could be caused by ice formation or accumulation of snow in roof valleys, gutters which are prone to ice-damming and dangerous icicles and also downspouts that freeze and clog.  The self-regulating heater cable automatically varies its heat output as the surrounding temperature changes.

self-regulating core

The self-regulating core at the centre of the EasyHeat SR trace heating cable is conductive and adjusts according to the surrounding temperature. When it is cold, the heating cable’s core has  many conductive paths that generate enough heat to keep water flowing from the roof to the ground. When the surrounding temperature rises, there are fewer conductive paths, therefore generating less heat.
