Evaporative heat cost allocators have been prohibited for new installations since December 2021. Existing buildings must be retrofitted with electronic wireless heat cost allocators by the end of 2026. This retrofit is essential to comply with current legal requirements and technical specifications and to ensure accurate consumption recording.
Evaporative heat cost allocators were first developed in Germany and Denmark in the 1930s. The relatively simple operating principle remained unchanged for a long time, but refined and more precise designs were continuously developed over the decades. It is undisputed that since the 1990s, electronic heat cost allocators have been considered a more technically sophisticated alternative to this type of device. The last significant advancements in evaporative heat cost allocators by most manufacturers took place in the 1980s. Since then, the technical possibilities have been largely exhausted.
Initial situation: Are evaporative heat cost allocators still permitted?
Evaporative heat cost allocators were long a cost-effective solution for recording consumption. The technology was developed in the 1930s and changed only slightly until the 1980s. Since then, the technology has been considered to have reached its technical limits.
The revised version of Heating Cost Ordinance (HKVO) The regulations of December 2021 stipulate:
- Only electronic heat cost allocators with radio transmission are permitted for new installations.
- Existing buildings must be retrofitted by the end of 2026.
- The aim is to comply with the EU Energy Efficiency Directive (EED) and to achieve greater climate protection.
Why is the conversion to wireless heat cost allocators necessary?
- Evaporative heat cost allocators measure consumption solely through the evaporation of a liquid.
- Electronic radio-based heat cost allocators precisely record temperature data and transmit it automatically.
- Remote meter reading reduces the effort required for annual readings and user changes.
- Interim consumption information is available at any time.
- Mounting the radios is usually straightforward; existing mounting plates can be reused.
This is how the conversion to radio readout works.
After commissioning, the existing Heat cost allocator and water meter through the power of Minol Connect wireless devices Replaced. In most cases, the existing mounting plates of the evaporative heat cost allocators being replaced can be reused for the new electronic wireless heat cost allocators. This eliminates the need for major installation work and prevents unsightly marks on the radiator. After installation, scheduling appointments for annual meter readings is completely eliminated. Time-consuming interim readings are no longer required when tenants change, as precise consumption measurement is always possible. Estimates will also no longer be necessary, since all measuring points are reached for consumption recording via wireless data transmission.
With Minol Connect wireless devices, you meet all the requirements of the new German Heating Costs Ordinance. Consumption data is read remotely throughout the year and securely transmitted to a cloud operated in Germany. There, it is available for various analyses, including the generation of... interim consumption information for the residents of the house.

With the LoRaWAN radio system Brunata Minol Connect, you create the basis for digital heating cost billing.
This is how landlords and property managers can collect consumption data securely, digitally and transparently.
What happens if the system isn't converted?
- After 2026, billing using evaporative heat cost allocators is permitted, but tenants can reduce their heating bill by 3 percent.
- This reduction can lead to significant financial disadvantages for landlords if energy costs rise.
- Timely conversion avoids conflicts and enables modern, convenient consumption recording.
Conclusion: Evaporative heat cost allocators are no longer permitted – act now!
The conversion to electronic wireless heat cost allocators is legally mandated and technically necessary. Landlords and owners should not wait until the last minute, as the conversion affects millions of apartments. Acting early ensures legally compliant and modern consumption recording.
Recommendations for landlords and owners
- Check retrofit offers early and plan the modernization by 2024 at the latest.
- Inform your tenants transparently about the switchover and advantages of wireless meter reading.
- Take advantage of Brunata Minol's equipment rental service for easy and cost-effective upgrades.
- Avoid cost risks due to potential rent reductions.
