1. A micro-combined heat and power system, comprising:
an exterior liquid cooled genset that is located outside of a building, the genset comprising an engine and a generator and being configured to output an electrical supply of between approximately between 1.2 kW and 4.4 kW;
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 that is 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;
another heat exchanger that is disposed in an intake air flow path of a heating system, the heating system having a blower and a secondary heat exchanger disposed downstream of the blower in a direction of intake air flow, wherein the another heat exchanger is positioned upstream of the blower in the direction of intake air flow; and
a pump that is configured, in response to operation of a thermostat that monitors a temperature within the building, to pump the heated liquid through the another heat exchanger to heat intake air in the intake flow path of the heating system.
