Analysis shows that reducing the heat carrier temperature boosts efficiency in apartment buildings, highlighting potential modernization methods.

Reducing heat transfer temperature significantly impacts heating efficiency, particularly with low-temperature district heating networks.
Modifying heating systems without architectural changes limits temperature reductions—achieving ultra-low parameters requires more radiators.
Incorporating existing heating devices post-renovation allows lowering temperatures to 60/40/20 °C but not to ultra-low levels without additional modifications.
Analysis conducted on hourly data for two typical heating months underlines the importance of appropriate radiator sizing for effective heating.

Streckienė et al. (2025) studied this question.
