What is a condensing water heater?
Condensing water heaters capture and recirculate what would otherwise be wasted energy in order to increase the units’ overall efficiency. Unlike standard (non-condensing) gas water heaters, which route hot water vapor through a flue and vent it out of the house, condensing units, such as the AO Smith 50-Gallon Power Vent Gas Water Heater , collect and recycle the water vapor. Of course, there are pros and cons to these units:
