An economizer system simply opens/closes a set of shutters to bring in cooler outside air when the outside ambient temperature is below the thermostat set point. It's kind of like free air conditioning :D.

Economiser utilises the heat from hot flue gases(exhaust gases) to heat the temperature of feed water,,
