Abstract: The invention is directed to a combination heater and electrical generator designed to allow continual use of the heating system in the absence of an external source of electricity. The system shares fuel and electrical inputs and also shares exhaust outputs so to facilitate ease of use installation as well as affording a small installation footprint.

Abstract: The invention is directed to a heat exchange module to help employ usable heat to pre-warm a water supply prior to entry into a tankless water heater. The module comprises an insulated housing having an inner shell having a top end, bottom end and cylindrical middle portion. A first intake attaches to the insulated housing which introduces cooling water from the cogeneration system, while a second intake feeds the water supply coils (positioned within the insulated housing) to effectuate heat exchange with the cooling water. After heat exchange, a first outlet removes cooling water for return to the cogeneration system, while a second outlet removes the water supply from the cooling coils. Upon removal, this water supply may be fed into a tankless water heater. A controller connected to both outlets and inlets optimizes efficient exchange of energy through timing introduction and removal of the water supply from the module.
