A condenser heat recovery based distilling process and apparatus is provided in various embodiments of the present invention. The apparatus includes a housing , at least one longitudinal trough connected to a pair of opposite sidewalls of the housing for storing contaminated water, the trough has a channel couplable to a compressor outlet for receiving a high pressure high temperature refrigerant vapor. Heat of the refrigerant vapor is rejected within the contaminated water. A plurality of contacting discs is stacked together on a connected to the pair of opposite sidewalls of the housing . The contacting discs are positioned within the trough in a manner that a portion of each of the contacting disc contacts the contaminated water and a remaining portion of each of the contacting disc being exposed to air.
