Box of Heating (Magic Box)

This is a box of gears and cogs, with a crank handle protruding from one side. When the crank is turned, heat emanates from the top of the box, more heat as the crank is turned faster. Through magical means, the energy of motion of the crank is magnified and turned into heat sufficient (with steady cranking) to heat a medium-sized room in winter.
