An air heating apparatus may comprise a housing with a path through an interior of the housing between openings in the housing. An isolating wall may divide the interior into primary and secondary chambers, and may have a transfer opening through which the path extends from the primary to secondary chambers. An air heating assembly may comprise an engine in the primary chamber, a heat generator in the primary chamber and connected to the engine, and a main heat exchanger in the secondary chamber and in fluid communication with the heat generator to transfer heat generated by the heat generator to air flowing along the path. The apparatus may include an air movement assembly configured to move air along the path and comprises a primary fan between the primary and secondary chambers to move air from the primary chamber to the secondary chamber.

A dual heating process is performed in the absence of an open flame. Heat is created by a rotating prime mover(s) driving a fluid shear heater. Heat is also collected from a cooling system of the prime mover, and from any exhaust heat generated by the prime mover. The heat energy collected from all of these sources is transmitted through heat exchangers to a fluid where heat energy is desired. The fluid being heated may be glycol or air, depending on the type of heat desired.

A power control system includes: a power generation device; and a storage battery that receives and stores power from a commercial power system or the power generation device. When power supply from the commercial power system is stopped, constant power is output from the power generation device, and the power is supplied to a first load, and surplus power thereof is supplied to the storage battery, and when a power storage rate of the storage battery is equal to or greater than a predetermined value, the surplus power is supplied to and consumed by a second load.

The present invention provides for a combined heat and power system including at least one engine, operatively coupled to a generator, having at least one first heat source adapted to provide a first thermal energy output at a first temperature range, and at least one second heat source adapted to provide a second thermal energy output at a second temperature range, at least one first heat exchanger, operatively coupled to said at least one engine, and adapted to selectively receive and transfer at least a portion of any one or all of said first thermal energy output and said at least one second thermal energy output; and a dynamically adaptive heat storage system.

A micro-combined heat and power (mCHP) system includes a liquid cooled variable speed genset that is located to the exterior of a building and that is provides heat and power to the interior of the building. The genset may be configured to output an electrical supply of between approximately between 500W and 40 kW. A coolant loop may extend from the exterior genset to the interior of a building and is configured to reclaim heat from one or more sources of waste heat at the engine, generator, oil and/or exhaust. The reclaimed heat is then transferred, directly or indirectly, to the air flow path of a building heating system. In one embodiment, the reclaimed heat is transferred to a liquid circuit via a liquid-to-liquid heat exchanger and thence to the cold air intake of a forced air furnace via a liquid-to-air heat exchanger. A thermostat may control heat transfer from the mCHP to the heating system.
