Abstract

An electric heating mat may include an outer sleeve having an interior, and an end with an opening to the interior. The end may be folded upon itself into a closed condition, and unfolded into an opened condition. When the end is closed, the interior of the outer sleeve may provide a sealed enclosure. The sealed enclosure may accommodate and protect internal components, such as heating elements, a power source, and associated controls. The heating elements, associated wiring, and an insulation layer may be provided in an inner sleeve, which may be insertable into the outer sleeve as a unit. When the end is opened, the opening provides access to the internal components. Such access allows the power source to be turned on to supply power to the heating elements.
