Enjoy Energy Efficient Hot Water At All Times!

The Greentherm 9000 offers an efficiency rating around 96% and innovative features for easy installation, operation, and simple maintenance. This not only saves you on installation cost but also running cost over the tankless’ lifetime. 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 also specifically designed with top connections for incoming water, this makes changing or removing the tankless much easier. In addition the system includes integrated drain ports so isolation valves are not needed! This alone saves homeowners a couple hundred dollars compared to other tankless systems that require the purchase. The Greentherm model includes unique integrated sensor technology which uses self-calibrating sensors to automatically configure flue length, gas type, and altitude without a gas analyzer. as a result this really helps homeowners making the switch to tankless water heating quick, easy, and cheaper than ever before.

The free Greentherm 9000 mobile app allows you to remotely control the water temp, activate the re-circulation pump, and monitor usage and sensor values from your cellphone or tablet. This is only included on the T9900 SEi model and an upgrade on the T9900 SE and T9800 SE models.

Indoor models can be easily converted from natural gas (NG) to liquid propane (LPG), and flexible venting options keep installation simple and fast.
