A heat transfer apparatus designed to control the temperature of objects placed within the apparatus over a wide temperature range of 42 to 180 degrees F. utilizing as a heating and cooling source a combined heating and air conditioning system of the type which control the temperature of a living space over only a typically narrow temperature range of between 65 and 80 degrees F. While serving as the source for the heat transfer apparatus, the combined heating and air conditioning system can continue to serve its primary function of controlling the temperature of a living space without difficulty. In a preferred embodiment, no internal modification of the heating and air-conditioning system is required for it to operate with the present invention as well as perform its primary function.
