| 20080223945 | HEAT EXCHANGER - Provided are exemplary embodiments, which may include a heating system with one or more heat exchangers. The heat exchangers may be capable of transferring heat in, to, and/or from the heating system to reduce inefficiencies, and/or allow the heating system to operate in a relatively more efficient manner. | 09-18-2008 |
| 20090242653 | Enviromentally distinctive cabin design and integrated recovery system - An integrated air flow induction system for heating a building is provided, the system comprising a centrally located fireplace hearth assembly and wall and floor beam sections defining hollow channels therethrough. The hollow channels are configured to return air back to the fireplace. The fireplace comprises a fire box, the fire box configured to retain a fire therein and further configured to receive returned air from the hollow channels, such that the returned air is heated. A plenum, located below the fire box, is configured to receive the returned air from the hollow channels. A fan, located between the fire box and the plenum, is configured to direct the returned air received by the plenum through the fire box, such that the air is heated by the fire box and dispersed throughout the building. | 10-01-2009 |
| 20110057046 | HEATING SYSTEM CONTROLLER, A HEATING SYSTEM AND A METHOD OF OPERATING A HEATING SYSTEM - A heating system, a method of operating a heating system and a controller for a heating system are disclosed herein. In one embodiment, the controller includes: (1) a system interface configured to receive thermostat calls from a thermostat, the thermostat calls including a heat pump thermostat call and an electrical heating elements thermostat call and (2) a processor coupled to the system interface and configured to select a starting heat load for the heating system based on the thermostat calls and a selected target discharge air temperature for the heating system. | 03-10-2011 |
| 20110073669 | APPARATUS AND METHOD FOR ENERGY RECOVERY - There is provided a heating system for a building comprising; i) a heater; ii) a media flow passage through which a medium heated by the heater passes in order to distribute heat through the building; and iii) a heat recovery apparatus for recovering latent heat of adsorption from a humid gas. The heat recovery apparatus comprises a) a gas flow passage connected at one end to a source of humid gas; b) a desiccant material provided within the gas flow passage such that the humid gas contacts the desiccant material and water vapour is adsorbed releasing latent heat of adsorption; wherein the media flow passage and gas flow passage are in heat exchanging relationship, such that when the desiccant material adsorbs water vapour from the exhaust gas the latent of the adsorption is at least partially transmitted to the medium. | 03-31-2011 |

| 20100072292 | Indoor Space Heating Apparatus - An indoor space heating apparatus comprising a heat pump including indoor and outdoor heat exchangers in fluid communication with a heat pump compressor. A blower is positioned to blow air over heat rejection coils of the indoor heat exchanger and into an indoor warm air reservoir. A combustion engine drives the heat pump compressor and a furnace transfers combustion heat from the combustion engine to the indoor warm air reservoir. | 03-25-2010 |
| 20110174891 | FURNACE BURNER BOX - An HVAC burner box includes a burner bank, a manifold and an air director located within an enclosure. The burner bank is oriented such that an outlet end of the burner bank is directed toward a first end of the enclosure. The manifold is located within the enclosure and adjacent an inlet end of the burner bank. The air director has a diffuser that is coupled to a side of the enclosure. The diffuser includes a plurality of openings located therethrough. The diffuser is configured to direct a first portion of a received airstream through the opening and toward the burner bank. The diffuser is further configured to send a second portion of the received airstream toward the manifold. | 07-21-2011 |
| 20110079653 | Heated Makeup Air Unit - A heated air makeup unit comprising a heating chamber with a modulated furnace one or more non-modulated furnaces air temperature control and efficient furnace operation over a wide heating rate range. The utilization of indirect fired furnaces in the heated air makeup unit is disclosed. A control system is included to provide control of heated air temperature to within +/−1 F.° using continuous control of the heating rate of the modulated furnace and stepwise activation and de-activation of the non-modulated furnaces in response to heating demand. A programmed combustion air flow controller programmed to provide optimal airflow for any gas flow in a flow range of a modulating gas valve is provided to assure combustion efficiencies of at least | 04-07-2011 |

| 20110057047 | HOT AIR HEATER - A hot air heater has a housing having formed therein an inlet port for sucking room air and an outlet port. A circulation fan, a burner, and a heat exchanger which causes to flow combustion gas from the burner through an inside of the heat exchanger are housed in the housing. The room air sucked by operation of the circulation fan into the inlet port is heated by the heat exchanger for blowing forward as hot air out of the outlet port. A supporting plate is disposed to support the heat exchanger inside the housing. In order to limit the temperature increase in the housing by heat transmission through the supporting plate, and in order to improve the thermal efficiency, the supporting plate is provided with radiating fins. Preferably, the radiating fins are made up of cut-and-raised pieces formed in the supporting plate. | 03-10-2011 |
