Condensing Gas Water Heaters - Tankless
This incentive applies to natural gas condensing tankless water heaters for hot water in commercial buildings. Tankless water heaters are also called instantaneous or on-demand water heaters that provide hot water without using a storage tank. Energy savings are achieved by installing a higher efficient condensing unit and the elimination of standby energy losses associated with the storage units.

More Information About Condensing Gas Water Heaters—Tankless
Tankless (also called instantaneous or on-demand) water heaters provide hot water without using a storage tank.
How Condensing Gas Water Heaters (Tankless) Work
Condensing tankless water heaters provide minimal hot water storage in the form of water in the coil, so standby heat and energy losses can be considered negligible. This reduced storage capacity (typically less than two gallons) results in the need for higher capacity burners to generate the flow of hot water necessary to serve equivalent peak loads.
- Higher average thermal efficiency
- Elimination of standby energy losses associated with storage units
- Energy and cost savings
Natural gas-fueled condensing tankless water heaters can be installed in all types of commercial buildings for all or part of their water heating needs. Suitable for new construction or time-of-natural-replacement installation where the pre-existing water heater was a natural gas non-condensing, power-vented storage unit.
