In addition, over time, standards of life are changing, so "Filling" was built 30-50 years ago, the building no longer meets the modern needs of its inhabitants. So, if in former times the total power of all of the apartment appliances do not exceed 2-3 kW, is nowadays insufficient and may be provided by regulations 7 kW. This means that the whole house-grid needs upgrading, as increased by several times the load to be replaced not only the cables, but also counters the whole automation equipment switchboard. Similarly is the case with heat supply. "Fifty years ago, the mere existence of the house central heating system has already been to a lot of happiness, because in some places we used wood furnace, – said Konstantin , director of thermal automatics Danfoss, a leading global manufacturer of energy efficient equipment for heating systems and heating buildings. – Today, people have different requirements: they want to be able at their discretion to regulate the temperature of air in homes, and this requires a comprehensive modernization of the heating system. Thus, installation of radiator thermostats to all heating batteries have significantly increased levels of comfort, because allows you to automatically adjust the temperature of heating devices for changes in the room. However, to get the best effect, it is necessary set in a house heating unit with automatic weather compensator. This will ensure the heating system in unison with the vibrations of the weather: in the freezing cold in the apartments will be warm and comfortable, and in periods of thaw, their inhabitants will be spared the unbearable closeness and the need for continuous ventilation.
