As for last week, the energy system’s peak load reached 1358 MW at 19:00 o’clock, 13th of February while it had risen by 46MW from the same period last year, and imported energy increased by 40MW.
Thermal conductivity of aluminum compared to pig iron is more efficient by 40-50 percent. So replacing pig iron radiators with aluminum radiators will increase the thermal conductivity by this amount.
