A hybrid heating system is disclosed. The hybrid heating system includes a compressor that is configured to compress refrigerant. The hybrid heating system further includes a first heat exchanger that is configured to adjust a temperature of water by exchanging heat between the water and refrigerant compressed by the compressor. The hybrid heating system further includes a second heat exchanger that is configured to evaporate refrigerant by exchanging heat exchange with exterior air. The hybrid heating system further includes a first boiler heat exchanger that is configured to increase a temperature of water using heat generated by combustion. The hybrid heating system further includes a second boiler heat exchanger that is configured to exchange heat between exhaust gas discharged from the first boiler heat exchanger and refrigerant flowing into the second heat exchanger.

A combination space and water heating apparatus includes a frame enclosing a water heating assembly and an air heating assembly. The water heating assembly is positioned in a top front portion of the frame and supplies hot water in response to a hot water demand. The water heating assembly includes inlet and outlet water connections through a top portion of the water heating assembly. The air heating assembly is positioned in a rear and bottom portion of the frame and supplies heated air in response to a space heating demand. Maintenance access to the air heating assembly is solely through a front section of the bottom portion of the frame.
