Stack economizers are specially fitted to install onto a boiler's stack, as close as possible to the flue exhaust. They capture otherwise-wasted heat and, by means of a water to air heat exchanger, utilize it pre-heat water before it enters the boiler for full heating.
A non-condensing boiler with a stack economizer on top essentially functions much like a condensing boiler. Thus, you get higher thermal efficiency (often raised from 80% to 90%), but at a much lower cost than replacing your existing boiler. As energy expenses continue to rise and stack economizers continue to improve in compactness, durability, and efficiency, they are an ever more attractive option.
For a boiler to safely and cost-effectively take a stack economizer, it must have a forced draft burner and should have an HP of at least 60. The economizer itself needs to be made of high-quality materials, like stainless steel, that will not rust, and its inner surface must be easily accessible to facilitate maintenance.
