Information & Tips
ENERGY STAR® certified gas condensing water heaters use similar technology as gas storage water heaters, but they condense water vapor in exhaust gasses and recover heat that would normally be lost as the exhaust is vented outside your house. By holding onto this heat, they can achieve an efficiency of 90 percent or higher. (Source: ENERGY STAR®)
High-efficiency gas condensing storage water heaters employ the same technology as standard gas storage water heaters: a glass-lined steel tank is heated by a burner located at the bottom of the tank. But a few basic changes make them operate more efficiently. Efficient models simply have better insulation, heat traps, and more efficient burners, improvements that have a modest impact on price lead to 8% less energy use.
Some very high efficiency models use a secondary heat exchanger that extracts more heat from the combustion gas, cooling it to the point where there is condensation– hence these types of heaters are called “gas condensing.” These gas condensing water heaters, like gas condensing furnaces, require venting through a vertical PVC pipe and a condensate drain.
The Connecticut Energy Efficiency Fund allows you to install high-performance gas heating and gas condensing water heating equipment without paying a premium price.
Pre-approval and a post-inspection from the participating utility are required if the rebate total exceeds $7,500.
Natural gas condensing water heaters require venting to expel the fumes created by their combustion processes, like other kinds of gas water heaters. With this type of model, you can vent fumes through a vertical PVC pipe and condensate drain. (Source: ENERGY STAR®)
High-efficiency condensing gas tank water heaters are designed with a helical internal heat exchanger rather than a straight pipe. This design reduces wasted heat and allows for more heat to be transferred into the water, which decreases energy use by 29% or more compared to a standard gas tank water heater.

The amount of hot water a natural gas water heater can deliver is determined by two things: its capacity (in gallons) and its first-hour rating. If your current water heater meets your needs, you can probably replace it with one the same size. But also look at its first-hour rating, which measures how much hot water it can deliver during a busy hour. The better the first-hour performance the more likely you can get efficient performance without buying a larger water heater. (Source: ENERGY STAR®)

Alert:
In line with the Department of Energy and Environmental Protection (DEEP) Final Determination of the 2022 – 2024 Plan, the Sponsors of Energize ConnecticutSM are discontinuing rebates and incentives for natural gas equipment as of December 31, 2024. Customers currently working with contractors to replace their natural gas equipment have until December 31, 2024 to complete the installation of measures to be eligible for applicable rebates. All natural gas equipment sales must take place on or before December 31, 2024 to be eligible for point of sale (midstream) incentives.
