Abstract:
1. A system for the space-heating of a building to a desired temperature and generation of electrical power comprising: a fuel-burning electric power generator being electrically connected to the building electrical service, the electric power generator being constructed and arranged to transfer heat produced by an engine of the electric power generator therefrom to a first circulating liquid stream; a heat exchanger for transferring said heat from said first circulating liquid stream into a second circulating liquid stream that delivers heat to different locations within the building an auxiliary heater located in the second circulating liquid stream so as to transfer additional heat to the second circulating liquid stream, the auxiliary heater being heated by an auxiliary heat source separate from and not thermally connected to the electric power generator; and a control module that operates a first circulating pump for driving the first circulating liquid stream and a second circulating pump for driving the second circulating liquid stream, the electric power generator, auxiliary heater, and flow control components in the second circulating liquid stream to maintain the desired building temperature while optimizing the utilization of the electric power generator as a source of heat for the building.
