The Greentherm 9000 offers an efficiency rating of EF .99, among the highest energy efficiency available on the market today, and innovative features for easy installation, operation and simple maintenance. You will enjoy an industry-leading 15-year warranty on the heat exchanger, and a full 5-year limited warranty on parts.
The Greentherm 9000 series indoor models were specifically designed with top connection 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.
Choose from nine models to ensure a configuration for any need from small home or condo to large commercial applications. Each model offers a simple conversion from natural gas (NG) to liquid propane(LPG), and flexible venting options to keep installation simple.
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 has a unique, stylish glass front and integrated Wi-Fi control (available as options on other models) enabling the homeowner to control the water heater remotely with a free mobile app.
