What is the difference between basic and consumer components?

The basic component expresses that part of the cost that is not dependent on the behaviour of the service recipients and is allocated to each according to the area of the flat or non-residential space. The costs of heat cover the cost of running the heating system, heat transfer, heat losses and costs of heating the common areas of the house.
The heat consumer component covers the cost of heat supplied to the flat by heating elements, the quantity of which can be influenced by the heat transfer to the radiators. It is split between service recipients according to gauge data using corrections or calculations. The calculation methods take into account the different demands of heated rooms on heat supply due to their location, the size of the radiators, the way of connecting the gauges and the internal temperature.
