A detachable heat bonnet for mounting over and around a conventional heat pump which confines and electrically heats air confined in spaced areas between the enclosure means and the exterior surfaces of the heat pump. This supplementary heat supplied by a small, high capacity electrical heater, prevents the actuating of the auxiliary heat strips of the heat pump, when the coolness of the inside air calls for the heating cycle.

A heat bonnet, for providing a supplementary source of heat for a conventional heat pump having an exterior casing exposed to outside air and an inside air coil and an outside air coil mounted within said exterior casing, which comprises: an enclosure means for confining air between said enclosure means and said heat pump exterior casing while allowing outside air to flow to said outside air coil and inside air to flow to said inside air coil, and a heating means, mounted inside said enclosure means, for heating said confined air and thereby warming said heat pump exterior casing, supplementing the heat otherwise available to said outside air coil of said heat pump during heating cycles.
