HOUSTON — The new Essency EXR water heater offers tankless advantages, such as hot water on demand, in a conventional tank water heater. The EXR installs like any other conventional tank water heater while delivering tankless-type performance. With its 80-gallon first-hour rating, the EXR outperforms all tank and tankless competitors in its class.
Water in the 55-gallon tank stays put, never entering the household system, so the tank requires no anodes and scale buildup is minimized. The stored water acts as a thermal heat source, heating incoming tap water as it passes through an oversized heat exchanger in response to household demand.
