Check water flow
The water flow through the boiler can
be checked with two different methods
shown below.
∆
T measurement
Check the temperature difference over
the boiler (
∆
T flow-return) when the
boiler is running on 100% load. The
nominal
∆
T is 20K and must be at least
between 15K and 25K for secure boiler
operation. An indication of the actual
flow rate can be found with the follo-
wing calculation (see table below for
nominal data):
∆
p measurement
Check the pressure difference over the
boiler (
∆
p flow-return) when the boiler
pump is running (burner on is not requi-
red). The nominal
∆
p for each boiler
type can be found in the table below,
actual
∆
p must be within:

cation of the actual flow rate can be
