More consumption units on new electronic heat cost allocators do not necessarily mean higher heating costs.
Replacing evaporative heat cost allocators with electronic heat cost allocators often leads to higher consumption units. However, this does not automatically mean higher heating costs. Modern devices precisely record even the smallest heat withdrawals. The improved measurement accuracy ensures fairer billing and lowers the price per unit.

Why do electronic heat cost allocators show more consumption units than evaporative devices?
After replacing evaporative heat cost allocators with electronic ones, consumption readings often increase significantly. Many tenants and landlords are therefore uncertain and fear higher heating costs. This concern is unfounded, because:
- Evaporative meters measure consumption based on the evaporation of a liquid, depending on temperature and time.
- Electronic heat cost allocators use sensors to record the radiator temperature and process the data precisely in the microprocessor.
This leads to better resolution and more accurate consumption measurement, especially with low heat consumption or lower heating surface temperatures.
Advantages of modern electronic heat cost allocators
- Precise detection of even the smallest amounts of heat, which evaporative devices cannot measure.
- More meaningful consumption figures for every season, especially during the transitional seasons.
- Uniform recording in all apartments of a building
The increased consumption units result in a larger total number of recorded heat consumption units in the building. However, since the actual energy consumption remains the same, the price per consumption unit decreases accordingly. The result: The total cost of the heating bill remains stable.
How will the switch affect the heating bill?
- The energy consumption readings of electronic devices can be fifty times higher than those of evaporative meters.
- This applies to all apartments in the building equally.
- The increased overall consumption reduces the price per unit of consumption.
- The heating bill remains at a similar level even with unchanged consumption.
Conclusion: More consumption units due to electronic heat cost allocators are not a disadvantage.
Switching to electronic heat cost allocators significantly improves measurement accuracy. The higher number of consumption units indicates precise recording, not increased energy consumption. Landlords and tenants benefit from fairer billing and reliable consumption data.
