Abstract
Heat losses from electric heating pads, blankets and pillows are reduced by aligning heat reflective strips or coatings over the top of a heating wire arranged inside the pads, blankets and pillows. By reducing heat losses, lower wattage can be applied to the heating wire to transfer the same amount of heat to a user as equivalent higher wattage blankets which do not have the heat reflective strips. By lowering the applied wattage, a more efficient blanket results.
