Fig. 47: Measuring the surface loss
How to measure the surface loss:
Enter the nominal power of the burner.
Pess "Proceed"
Enter the surface temperature T
S
of the single
area and its dimensions (width x height).
Measure the average surface temperatures
with the Special Wall Temperature Probe con-
nected to the Wöhler DC 410
FLOW
and save it
by pressing the
“Accept” key.
Do this for every partial surface
Fig. 48: Converting the surface loss in
potential improvement points
The meter will calculate the surface loss q
r
(r:
radiation). The surface loss will be referred to the
heat emission and then converted into improve-
ment potential points according to the DIN EN
15378, national appendix. The conversion into
improvement potential points is done according to
the graphic in Fig. 48: Converting the surface loss
in potential improvement points
After the measurement of the surface loss has
been completed, "Surface loss" will be marked by
a tick mark in the "Energy Utilization Check"
screen.
Evaluation
Fig. 49: Evaluation of the Energy Utili-
zation Check
The menu item "Evaluation" presents all results
and the corresponding improvement potential
points according to DIN EN 15378. These have to
be registered in the Energy Utilization Check cer-
tificate.
