Check water flow
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):
q
= (∆T
/ ∆T
) * q

∆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:
0.35*Δp
≤ ∆P ≤ 1.75*∆p

indication of the actual flow rate can be
found with the following calculation (see
table below for nominal data):
