The system installs a heat meter or cost allocator on each flat's radiators or heating circuit, recording actual consumption. Part of the heating cost is then settled according to actual individual consumption, the rest in proportion to floor area.
Experience shows the rollout can deliver 10-20 percent heating savings at building level, as owners regulate their consumption more consciously. The effect is strongest when measurement data is fed back regularly, even monthly.
The decision falls to the general meeting and, since it affects every flat, requires thorough prior information: the cost of installing meters, who operates and reads the system, and how the settlement method changes.
The panel renovation subprogramme explicitly supports building such smart metering and control technologies, so it is worth treating this as one project with roof insulation or heating modernisation.
An important practical detail: annual meter readings and preparing the settlement add work for the bookkeeping, so this typically appears as a separate but transparent item in the common cost statement.
Before every rollout Merbo organises an information forum for owners, presenting the expected change in settlement with concrete numbers.
