Systems and methods utilize a cogeneration system for providing heating, cooling, and/or electricity to an enclosure. The system includes a heat engine for heating and supplying electricity to the enclosure. Coupled to the heat engine is a first conduit configured to transfer fluid from the heat engine to the enclosure to transfer thermal energy from the fluid to the enclosure. The system further includes a heat pump configured to supply at least heating and cooling to the enclosure. Coupled to the heat pump is at least a second conduit. The second conduit is configured to move fluid from the heat pump to the enclosure to transfer thermal energy from the fluid to the enclosure.

The present invention provides an energy storage system (10) for a use with a boiler (20). The energy storage system (10) comprises a plurality of thermal energy storage banks (101, 102, 103, 104). Each thermal energy storage bank (101, 102, 103, 104) comprises phase changeable material having a predetermined phase transformation temperature. The energy storage system (10) also includes an extraction device (105; 1 15) configured to recover waste energy from the boiler (20). The extraction device (105, 1 15) is operable to extract waste energy from the boiler (20) and feed that energy to at least one (101) of the thermal energy storage banks (101, 102, 103, 104). A controller (106) is arranged, in use, to activate the extraction device (105, 115) in response to operation of the boiler (20).

An energy generating system for generating thermal energy and electrical energy for a premises. The system includes an engine that drives an AC power generator to supply supplemental or standby power to the premises. The thermal energy given off by the engine is also coupled to the premises to provide heat thereto. A processor controls the various parameters of both the energy generating system and the premises to coordinate the proper heating and cooling thereof.

Heat transfer systems employing a heat transfer means (e.g., circulating fluid, thermally conductive material, etc.) to transfer heat from the heat source (e.g., fireplace, wood stove or other heat source) to a remote location of a home, residence, building or other structure.

A fluid circulation type heating apparatus includes: a circulation line; a heat radiation member installed on the circulation line; a boiler configured to heat and expand a fluid; a storage tank configured to store the fluid and to supply the fluid to the boiler; a controller configured to control the boiler; and a housing configured to accommodate the boiler and the controller. The apparatus further includes: a backflow prevention means removably installed in the housing and configured to, when mounted to the housing, communicate with the circulation line disposed between the boiler and the storage tank, the backflow prevention means configured to allow the fluid to flow in one direction through the circulation line.

There is described an apparatus for storing heat. The apparatus comprises a thermal mass for storing heat, the thermal mass having a first surface and a second surface. Fins are provided on the first surface and the second surface for accelerating heat transfer to and from the thermal mass. A displacement mechanism is secured to the thermal mass for translating the first surface to a first environment, e.g., a duct, while removing the second surface and its fins from a second environment, e.g., outside, and for translating the second surface to the second environment while removing the first surface and its fins from the first environment.

A system includes: a heat generator obtaining heat from a heat source and having a generator outlet port and a generator return port; a central heating circuit having a heating feed port and a heating return port; a tank having a top portion and a bottom portion, the tank containing a heat storing medium; a first tapping coil immersed in the heat storing medium in the bottom portion of the tank; and a second tapping coil immersed in the heat storing medium in the top portion of the tank The heat generator, second tapping coil, central heating circuit, and first tapping coil are fluidly connected in series to allow fluid to flow from the heat generator via at least one of the second tapping coil, the central heating circuit, and the first tapping coil back to the heat generator The system includes first, second and third three-way valves.
