CA 2073106
A condensing gas furnace/heat exchange system is provided which includes two subsystems. A first subsystem includes an outdoor coil, an indoor coil, a reversing valve and a compressor, and the heat exchange medium thereof is a liquid refrigerant, such as Freon TM. This subsystem is operative in heating, heat-augmented heating and cooling modes of operation, and in the heat-augmenting mode of operation, gas burners provide additional BTU's to the system. The other system includes an outdoor coil, an indoor coil and a pump, but excludes a compressor or a reversing valve, and utilizes a heat-exchange medium such as water, ethylene glycol, glycol per se or a non-refrigerant. The pump merely pumps the glycol through the system which absorbs heat/BTU's from the flames of the burner which are eventually transferred by the indoor coil to heat an associated dwelling or the like.
