Where the use of individual meters is not technically feasible or where it is not cost-efficient to measure heating in each building unit, individual heat cost allocators shall be used to measure heat consumption at each radiator unless it is shown by the Member State in question that the installation of such heat cost allocators would not be cost efficient.
Če uporaba individualnih števcev tehnično ni izvedljiva ali merjenje ogrevanja v individualni stavbni enoti ni stroškovno učinkovito, se uporabijo individualni delilniki stroškov ogrevanja na posameznem radiatorju, razen če zadevna država članica izkaže, da namestitev takšnih delilnikov stroškov ogrevanja ne bi bila stroškovno učinkovita.
