6.3 Heating Check (option)
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>.
The gas losses measurement is to be performed 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 measurement
results in negative points is available under the menu
point „Results“.
The surface losses measurement is performed by a temperature sensor specific for surfaces.
The temperature difference between boiler surface and room temperature (air temperature
sensor) is determined and the percentage loss is calculated. 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 proceed 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>
