Pump Information

Heating Circuit / Boiler Pumps
Viessmann offers a variety of Grundfos heating circuit
/ boiler pumps which meet typical Vitodens system
installation requirements (see "Heating circuit pump
(field supplied)" or "Boiler pump (field supplied)" in the
Installation Examples starting on page 36). See tables
below for recommended pumps. Refer to the graphs
on page 9 for the proper waterside boiler friction loss
calculations. The following pumps have been selected
based on boiler heat exchanger head loss and boiler
piping to a low-loss header.

Vitodens 200-W B2HA 88-150, 311- 530 Technical Data
Before using the following pumps for a DHW tank
application, find out the proper pressure drop through the
tank, the required temperature difference through the coil
and system piping head loss of the domestic hot water.
IMPORTANT
Pump selection must be based on accurate system flow
and pressure drop calculations (incl. DHW sizing).
