    This Energy Star approved tankless water can produce enough hot water for 2-3 major applications in most homes. The Bosch Greentherm T9800 SE 199 Tankless Water Heater features top-mounted water connections which lowers labor costs and parts requirements and makes for an easy conversion from an existing tank water heater.

You will enjoy an industry-leading 15-year warranty on the heat exchanger, and a full 5-year limited warranty on all other parts.

    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.

    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.

    Beautiful, 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 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.

    The Bosch Greentherm T9800 SE 199 is Bosch's replacement for the Bosch Greentherm C 1050 ES and the Bosch GWH C 800 ES.

    Bosch Greentherm T 9800 SE 199 NG/ LP Water Heater Install Review by Roman Weisman
    The product was securely packed, with extra cushions, resulting in safe arrival of the product.

    Pro Water Heater Supply was very professional in explaining and selecting the right unit matching my sqft house, water usage and needs.
    Ended up with the T9800 SE 199 NG unit.

    The T9800 SE 199 NG:
    The unit makes sounds which are strange at first, after opening any hot water valve. It seems to me that this is normal, but I would still like to mention it.

    The unit is very quiet, has an awesome slick and futuristic design which reminds me of an iPod.

    The hot water is endless, so unlike tank units, I found myself adding more cold water as it was too hot after some time, unlike tank water heaters where you need to reduce the cold water to have more hot water since the tank has limited amount of hot water.

    I did not experience any kind of sudden pressure drops or any kind of sudden cold / hot water bursts - in other words, the heat is constant.

    Also, I would not try to overload the system by using all the hot water in the house simultaneously and using all the products which consume gas / hot water simultaneously, as this is just not right. Instead, schedule your hot water consumption accordingly.

    Bottom line:
    I would recommend this unit to anyone, and for those wondering about detailed installation process, feel free to check out my installation on youtube: (Posted on 4/12/19)
