Claim 17:
18. A micro-combined heat and power system, comprising:
an exterior genset located externally of a building and comprising a variable speed engine and a generator, the variable speed engine being configured to be modulated between a running speed of approximately 500 RPM to 5000 RPM, and the genset being configured to output an electrical supply of between approximately 0.5 kW and 40 kW, the genset having
a coolant loop that is configured to heat coolant from an initial temperature to an elevated temperature via heat transfer from the genset, the coolant loop extending from the exterior genset to an interior of the building;
a coolant-to-liquid heat exchanger disposed within the interior of the building and that is configured to heat liquid disposed within a liquid circuit via heat transfer from the coolant in the coolant loop;
a liquid-to air exchanger that is disposed in an intake air flow path of a forced air furnace system, the forced air furnace system having a blower and a secondary heat exchanger disposed downstream of the blower in a direction of intake air flow, wherein the liquid-to air exchanger is positioned upstream of the blower in the direction of intake air flow; and,
a pump that is configured, is response to operation of a thermostat monitoring a temperature within the building, to pump the heated liquid through the liquid-to-air heat exchanger to provide intake air in the intake flow path of up to 400,000 BTU of heat.
