About Condensing Water Heaters water heaters
Condensing water heaters extract additional heat from the flue gas before exhausting it — increasing UEF efficiency from typical 0.62–0.67 (atmospheric) up to 0.84–0.97 (condensing). The technology requires sealed-combustion 2-pipe PVC venting and a condensate drain (the recovered heat condenses water vapor from the flue gas, which must drain to a floor drain or condensate pump).
For typical 3–4 person households on natural gas:
- Atmospheric gas tank (0.62 UEF): $280–$380/year operating
- Condensing gas tank (0.84 UEF): $200–$280/year operating
- Condensing gas tankless (0.96 UEF): $180–$260/year operating
Condensing tank vs atmospheric tank: $80–$120/year savings. Over a 12-year...
