A METHOD, A HEAT METER AND AN INSTALLATION FOR DISTRIBUTING HEATING COSTS

摘要

Heating costs are calculated on the basis of the difference in temperature between a heat source and the room temperature. According to the present invention a time mean temperature is first determined over a given period of time, which is common to both a heat source meter and a room temperature meter. In principle said meters are structured in the same way and shown by (12) in Figure 3. A temperature sensor (13) is provided that emits signal to a measurement amplifier (14). All measurements are added (15) and divided by the number of measurements (16) since a predetermined starting point. The result may be shown (17) or emitted via wires or wirelessly from an amplifier (18).
