Controlled Energy Corp. (CEC) has introduced the Pro Tankless by Bosch 635 ES gas water heater. The model's design combines tankless water heating with an elegant simplicity. The 635 ES incorporates direct vent room-sealed combustion technology, which, along with its ability to hang on a wall, allows the water heater to be installed in small spaces. It can be vented horizontally or vertically, making installation easier. And, the unit is powerful enough to supply hot water to two showers running simultaneously.
