Benefits of High-Efficiency Gas Tank Water Heaters

How it Works
What is a high-efficiency condensing gas tank water heater?
A. O. Smith high-efficiency condensing gas tank water heaters operate using the same technology as a standard gas storage water heater and are just as easy to install. The water heater maintains a tank of hot water available for immediate use. As hot water is drawn out of the tank, it is refilled with cold water. The electronic controls monitor the water temperature and reheat the tank when necessary.
The primary difference is that the high-efficiency condensing gas tank water heaters are designed to transfer and retain more heat into the water than a standard gas water heater. This reduces the amount of wasted heat and reduces total energy use.
