Case Study

Maximizing Boiler Efficiency with Hybrid Boilers

A hybrid boiler plant is defined as a hydronic heating plant combining condensing and non-condensing boilers.  This system is designed to take advantage of the best properties of both types.  Through the proper system design, control and boiler selection, we may be able to save the same amount of energy associated with a properly designed full condensing plant at a cost of one third to one half of an all condensing plant.
