Heat pump is more efficient. If you use electric heaters, 1 joule of electric energy will produce 1 joule of heat energy. If you use heat pumps, 1 joule of electric energy can pump several joules - perhaps up to 5 or 6, depending on the outside temperature, and the efficiency of the heat pump - of heat, from the outside to the inside.
