Vitodens 200-W, B2HA 19 to 80 Technical Data

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 35). See tables
below for recommended pumps. Refer to the graphs on
page 10 and 11 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.

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 (includes DHW sizing).
