Sample of a schematic drawing of Stack Economizer Installation: This schematic drawing provides the layout of a sample stack economizer/boiler combination service water pre-heating system. The system piping shows how the cold intake water for the service hot water is channelled through a boiler's stack economizer heat exchanger to be pre-heated by recovered boiler flue-gas waste heat. The diagram also shows the indirect heating of the service hot water storage tank via a separate boiler loop.
