What is the Difference Between a Condensing and …

A non-condensing tankless water heater vents the scalding byproducts, which cool down outside the unit. This stuff is hot, with temperatures around 150 degrees C, and must be vented through heat resistant, corrosion resistant channels. That means: The materials to build the non-condensing unit are expensive. When heat is vented, energy is wasted.
