Front-end loading is gaining momentum as a boiler system design strategy, as higher-efficiency condensing boilers replace older boiler technology and system control intelligence continues to improve.

Two types of boilers can be better than one—especially when trying to minimize operating costs over the course of a heating season. By combining a large mass, non-condensing boiler with a high ...
