Patent attributes
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 vapor 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 vapor from the exhaust gas the latent of the adsorption is at least partially transmitted to the medium.
