What customers say
Customers appreciate the Bosch tankless heater's premium build quality and compact design, which reflects the brand's reliability. When correctly sized, it provides continuous hot water, a major benefit over traditional tanks. However, a consistent theme involves the substantial electrical requirements. Many users face unexpected costs due to necessary electrical panel upgrades and dedicated circuits. Furthermore, performance consistency varies significantly by climate. While excellent in warmer areas, users in colder regions often find the unit struggles to meet flow rate demands simultaneously. Success hinges on meticulous sizing calculations based on incoming water temperature and ensuring electrical readiness to avoid performance disappointment.
