Option Heating Check - Ecom EN3 Instruction Manual

6.3 Option Heating Check

The heating check is a simple, expressive process to evaluate a complete
heating plant (heat production, distribution and transfer) from the energetic
point of view. Hereby the single plant components get inspected by the
heating engineer in a combination of measurements and visual assessment
and valued in regards of their energetic quality acc. to a negative point
system of maximum 100 points. The higher the score, the farer the current
plant is away from the desirable energetic stand and the higher the energy
saving potential would be if modernization measures are conducted. In
combination with the special probes required hereto, the ecom-EN3 is able
to perform the measurement of the heating check parameters: gas losses,
ventilation losses and surface losses. Out of the main menu point
"Diagnostics", select the sub-menu "Heating Check" and confirm with
<Enter>.

Once the menu point is called up, the boiler performance must be inputted.
To easy the measurement width, depth and height of the boiler can also be
entered (dimensions will be memorized for surface calculation). Please pro-
ceed as follows:
• activate respective input window with <Enter>
• inputs values using the keys numerical function
• confirm input with <Enter> or
• adjust values using the cursor keys <Right / Left>

The gas losses measurement is to be per-
formed with the instrument´s sampling probe in
the gas core stream after menu call up. Once
the measurement is recorded with <Save>
(disk symbol) the conversion of the measure-
ment results in negative points is available un-
der the menu point „Results".
The surface losses measurement is performed
0 ppm
by a temperature sensor specific for surfaces.
The temperature difference between boiler sur-
face and room temperature (air temperature
20 °C
sensor) is determined and the percentage loss
is calculated.
