Heat recovery can refer to:
Cogeneration or combined heat and power (CHP), use of a heat engine or power station to generate electricity and useful heat at the same time Energy recovery, any technique or method of minimizing the input of energy to an overall system by the exchange of energy from one sub-system Energy recycling, process of using energy that would normally be wasted Exhaust heat recovery system, conversion of waste heat energy in exhaust gases into electric or mechanical energy reintroduced on the crankshaft MGU-H, an electrically assisted turbocharger and electric turbo-compound used in Formula One cars from 2014 to 2025 Goodsprings Waste Heat Recovery Station, Heat recovery steam generator, a heat exchanger that recovers heat from a hot gas stream Heat recovery ventilation or mechanical ventilation heat recovery, ventilation system that recovers energy by operating between two air sources at different temperatures to reduce heating and cooling demands of a building Waste heat recovery unit, an energy recovery heat exchanger that transfers heat from process outputs at high temperature to another part of the process for some purpose, usually increased efficiency Water heat recycling, use of a heat exchanger to recover energy and reuse heat from drain water
