The adjusted total consumption of gas heating during the measurement period was 33,542.33 kWh. To allow a comparison with today’s state of heating technology with the use of condensing boilers, the corrected total consumption was calculated by a further 10% down. This corresponds to the consumption value that would be reached by gas heating of condensing boilers in the measured object.
Therefore, the total consumption of gas heating in condensing technology was 30,188.1 kWh in the measurement period.
To have a comparative base of energy consumption, it was referenced to specific residential areas. Accordingly, the following was received:
The total consumption of infrared heating related to the living space was in consequence 7,305.92 kWh/102.6 m2 = 71.21 kWh / m2 at the measurement period.
The adjusted total consumption of gas heating in relation to the residential area was in consequence 33,542.33 kWh/160,7 m2 at the measurement period.
The accounting total consumption of gas heating in heating technology with condensing boilers, based on the residential area, was therefore 30,188.1 kWh/160,7 m2 at the measurement period.
The consumption values related to the residential surface area are presented in Figure 4.8. = 208.73 kWh/m2 = 187.85 kWh / m2
The infrared energy consumption is only 34/1% when compared to low-temperature gas heating, and only 37.9% when compared to gas heating in condensing technology with boilers.
This means that the final energy consumption of gas heating is 2.5 times more than the final energy consumption of infrared heating.
