Replacing a tank?

The Greentherm 9000 series indoor models were specifically designed with top connections for water, integrated drain ports so isolation valves are not needed, and a unique integrated sensor technology that auto-calibrates, making the switch to tankless water heating quick and easy.

The most common model for City Home Comfort customers is the Bosch Greentherm T9800 SE 199. This provides best in class hot water capacity and reliability at an attractive price.

For smaller homes, the Bosch Greentherm T9800 SE 160 is also a popular product.

Beautiful and Hardworking

All Greentherm 9000 Series models feature sleek, rounded corners on the metal cabinet, making these water heaters as beautiful as they are energy-efficient. The premium Greentherm 9900i SE model comes standard with a glass front and integrated Wi-Fi control (available as an option on other models).

Control Remotely from Mobile

The free Greentherm 9000 mobile app allows you to remotely control the water temp, activate the recirculation pump, and monitor usage and sensor values from your cellphone or tablet.

Options for Everyone

Choose from seven models to ensure a configuration for any need from small home or condo to large commercial applications. Indoor models can be converted from natural gas (NG) to liquid propane (LPG), and flexible venting options keep installation simple.
