Abstract
A system for recovery systems improving heat recovery from hot waste water is provided whereby cold feed water is preheated by means of extracting heat from hot waste water by passing said hot waste water and said cold feed water through a heat exchanger. Said preheated feed water is directed simultaneously to the hot water heater and to mixing valves at the point of usage of tepid water. Equal volumes of waste water and cold feed water flow through the system.
