13.3 Advanced tank loading commercial hot
water system
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.
See Chapter 5.2 for recirculation pump parameters
System parameters:
f Maintain a 20 degree difference between tankless
set-point and desired tank temperature.
