Bosch Introduces Condensing Tankless Water Heater

High-performance models designed for easy installation and maximum efficiency

The Bosch Greentherm 9000 Series is a new line of tankless gas condensing water heaters that offers nine models for high-efficiency domestic hot water in residential or commercial applications, adding new features for easy installation, operation and maintenance. The series features an energy factor of 0.99 with thermal efficiency of 100 percent. It achieves temperature stability of plus- or minus- 2 F through the active bypass, and its advanced technology controls output capacity, optimizing comfort and efficiency by combining the burner’s pulsating mode with the bypass valve to achieve the desired outlet temperature, even at low flow rates. Its wide operating range — between 9,000 and 199,000 btu — saves energy when hot water demand is low.

Other features include:

  • Industry’s highest Energy Factor of 0.99, Thermal Efficiency of 100 percent
  • Integrated Wi-Fi control enables remote user-control of water heater via free mobile app
  • Built-in recirculation pump allows easy plug-and-play installation of home recirculation system
  • Active bypass provides unparalleled temperature stability and eliminates the need for a buffer tank, even with varying flow rates and supply water temperatures
  • Dedicated commercial and residential models for indoor or outdoor installation

Each model offers simple conversion to LPG using the included manifold injector kit, which eliminates stocking both LP and NG units, thus saving the wholesaler’s inventory cost.

Installation permits up to 60 feet of venting with two-inch pipe, or 280 feet of venting with three-inch pipe, using a wide range of venting material options. It may be used with half-inch or three-quarter-inch gas line with appropriate connection, and a built-in recirculation pump allows for simpler installations. The Greentherm 9000 Series requires no dedicated return line, decreasing wait time for hot water at the tap, thus reducing water waste and saving an estimated 11,000 gallons a year per household.

The commercial Greentherm 9000 models offer heavy-duty primary and secondary heat exchangers for longer lifespan, and deliver water supply temperature to 180 F. Systems also can be cascaded up to 24 units to achieve flow rates of more than 200 gallons per minute – ideal for commercial buildings, schools and hotels.

Residential units offer a standard 15-year limited warranty on the heat exchanger and a five-year limited warranty on parts.
