What customers say
Customers highly value the Bosch TR6100C-18 for its energy efficiency and compact design, noting its reliable performance for point-of-use needs or smaller homes. The space-saving profile is a significant advantage over traditional tanks. The core positive theme centers on delivering continuous hot water efficiently. However, feedback consistently points to flow rate limitations, especially when multiple fixtures run simultaneously, which is typical for electric tankless systems with cold incoming water. While the unit quality is praised, potential buyers must account for necessary electrical infrastructure upgrades. Overall, it is viewed as a smart investment for those prioritizing energy savings and space, provided usage expectations align with its technical capacity.
