Economizers (US and Oxford spelling), or economisers (UK), are mechanical devices intended to reduce energy consumption, or to perform useful function such as preheating a fluid. The term economizer is used for other purposes as well. Boiler, power plant, heating, refrigeration, ventilating, and air conditioning (HVAC) may all use economizers. In simple terms, an economizer is a heat exchanger.

thumb|400px|Types of recuperator, or cross plate heat exchanger A recuperator is a counter-flow energy recovery heat exchanger that recovers waste heat in the supply and exhaust air streams of an air-handling system or in the exhaust gases of an industrial process. Generally, they extract heat from the exhaust and use it to preheat air entering the combustion system, reducing the need for fuel and boosting the system's energy efficiency.
