13.3 Advanced tank loading commercial hot
The following application outlines an advanced tank loading ap-
plication for commercial hot water systems (e.g. hotels, ﬁ tness
centers). This design allows for complete isolation of the system
for maintenance reasons and gives the ability to bypass certain
system components in case of failure. A second hot water stor-
age tank is shown for additional hot water supply and back up
in case of tank failure.
Applicable models: Bosch 830 ES, 940 ES, 940 ESO,
C 950 ES, C 1050 ES, C 1210 ES, C 1210 ESC.
