Reader question: How do I classify an announced device exchange to make devices remotely readable and prepare the specific installation appointment?
There is a notice in the building: the heat cost allocators or hot water meters will be converted to remote readability. Before the appointment you need answers about the actual scope of work. A device exchange, a new cost item and a data protection notice are related documents, but they answer different questions.
Exactly what is to be replaced?
Ask for the device type, affected rooms, executing company, planned date and contact person for deviations. Is it about heat cost allocators, heat meters or hot water meters? Cold water meters are not captured by the same heating cost regulation solely because of their name. A announced exchange of other devices requires its own classification.
Within the scope of the Heizkostenverordnung the owners’ side must record the proportional consumption of heat and hot water and equip the rooms accordingly. Users must tolerate the equipment; the choice remains with the owners’ side within the framework of § 5. [HeizkostenV4] Therefore you should clarify any concrete dispute about scope or procedure specifically and not just answer with “the old devices still work”.
What is the significance of the end of 2026?
Remotely readable means according to § 5 HeizkostenV that the equipment can be read without access to individual units. That is a statutory functional description. It does not yet say which transmission procedure your building uses, whether your own WLAN is needed or which user interface is offered. These product characteristics must come from the actual system documents. [HeizkostenV5]
For the existing equipment referred to in § 5 paragraph 3 that has not hitherto been remotely readable, the regulation generally requires retrofitting or replacement by 31 December 2026 according to the requirements stated there. The standard contains special individual exceptions, for example in cases of technical impossibility or disproportionate expense or undue hardship. [HeizkostenV5] A notice with the date proves neither the existence of an exception nor a concrete technical suitability. Older devices that are already remotely readable also have their own transitional rule in paragraph 4. “All meters must be new this year” would be too sweeping.
Practical preparation of the appointment
Confirm a suitable access or report a concrete scheduling problem in good time with reachable feedback. Clarify which areas should be freely accessible and who will move larger items. Ask about any planned supply interruption, its actual period and necessary preparation. These are editorial organisational suggestions, not blanket notification periods asserted here.
At the appointment, date, device designation and a comprehensible replacement receipt are helpful. As far as they can be read and are safely accessible, your own photos before and after the exchange can support the actual assignment. Have them explain which old and new values were documented and how they will be used in the current billing period. Do not change any mounting, seal or device settings yourself.
Examine objections to device rental concretely
If the owners’ side wishes to rent the equipment or procure it by another form of transfer of use, § 4 paragraph 2 HeizkostenV contains a special prior notification including a statement of costs. According to this rule the measure is inadmissible if the majority of users object within one month of receipt of the notification. [HeizkostenV4]
This rule is not a personal choice between arbitrary device manufacturers and not a general one-person veto against every conversion. Present the actual cost notification promptly for review in case of a dispute. From an unclear cost item alone the entire access appointment cannot be conclusively assessed.
Ask data questions as concrete questions
§ 6b HeizkostenV limits collection, storage and use to the owners’ side or an authorised third party and to the extent necessary for cost allocation/billing or the information obligations under § 6a. [HeizkostenV6b] The standard is not a clearance for arbitrary use of consumption data.
Therefore ask for the competent body, the intended reading route and the data protection information actually provided. Do not claim that the system is automatically insecure, nor that the statutory conversion proves complete data security of your particular device. An individual technical or data protection assessment requires the actual documents.
Three final questions in your own case
In the fictional case a female tenant receives an exchange appointment but no understandable description. She first clarifies that only the heat cost allocators are affected. A announced hot water interruption turns out to have been taken over by mistake; the order is corrected. She submits the open question about device rental separately for review with the cost sheet received.
In the end it should be clear: which devices were actually exchanged, which replacement receipt exists and which cost or data question is still open with whom? The monthly information and a later heating cost statement will then be reviewed on the basis of their own requirements.
