We installed the Bosch T9800 SE 160 after renovating our 3,100 sq. ft. home and wanted a reliable water heater that could handle a larger household. With four adults living in the house, hot water demand can be high, especially when showers, laundry, and kitchen use overlap. This system has handled our daily needs extremely well.
We noticed the biggest difference in the consistency of the water temperature and how quickly hot water is available throughout the home. The unit operates quietly, has a modern, compact design, and features easy-to-understand controls. The team helped us choose the right equipment for our home and carefully completed the installation. Excellent product and excellent service experience.

We purchased the Bosch T9800 SE 160 because we wanted a reliable tankless water heater that could provide better hot water performance throughout our home. One of the main reasons we chose this model was the ability to handle higher demand without long waits or temperature changes during daily use.
With a flow rate of up to 34 liters per minute, the system easily keeps up when multiple water outlets are used simultaneously. We can run showers, use the kitchen sink, and handle other hot water needs without worrying about inconsistent temperatures or running out of hot water.
After installation, we noticed that hot water reaches our fixtures much faster and the temperature remains stable during use. The unit operates quietly, has a compact design, and the controls are simple to understand. The installation team explained everything clearly and made sure we knew how to use the system properly.
We are very happy with the Bosch T9800 SE 160 and would recommend it to anyone looking for a powerful and dependable tankless water heating solution.

We purchased the Bosch T9800 SE 160 after researching different tankless water heater options for our home. We were looking for a system that could provide reliable hot water throughout the day while also being more efficient and easier to manage than a traditional setup.
The performance has been excellent so far. Hot water is available quickly, the temperature remains steady, and the system handles periods of higher demand without noticeable drops in performance. We especially appreciate that multiple fixtures can be used simultaneously without worrying about inconsistent water temperatures.

There is no crackling sound like other boilers when the water is drawn and heated.
