I am German and live now since 2017 permanently in Estonia on a Bio Farm. I lived in France (35 years) and Germany and in both countries the heating costs are the real cost based on the device installed on the Radiator or an energy counter in the hor water pipe from the heating system which is much more precise, because they are methods to fool the device (condensation based) on the radiators. However, measuring the used energy directly on the radiators is standard in Germany for more the 40 years. Please, Milosz Maksimovic, change your petition that it reflect also the concerns of Bogdan Parubok, because they are 100% valid. I will sign the petition.
