What is a Boiler Economizer? (with pictures)

2019-8-16 · Some boilers are designed with economizers built in, while in other cases, an economizer can be fitted on after the fact. Boilers operate by heating water to make steam, and using that steam for heat or energy generation. For the most part, a boiler is fairly efficient, but there is some heat loss when the byproducts of combustion are vented.
