This system can be installed down flow, and is designed to operate for decades, provide powerful heating capability, and, best of all, keep your heating bill affordable at the same time. It does the latter via its 80% AFUE energy efficiency rating. That mark of quality ensures 80% of every dollar you spend on heating fuel gets turned into real, effective heat for your home.
