The thermal energy consumed in the building is measured. The parts of the heat meters are the flow sensor, temperature sensors and the heat consumption meter. The flow sensor measures the volume of circulating district heating water. The temperature sensors constantly measure the temperature of water going into and coming out of the building. The heat consumption meter calculates the thermal energy consumed. Consumption is shown in megawatt-hours (MWh). The heat supplier owns the metering equipment..
For example, the following data can be read from the heat meter:
• thermal energy
• volume of circulating district heating water
• momentary cooling of the district heating water
• momentary temperatures of the supply and return water of the district heating water
• momentary power and water flow
The customer sends meter readings to the heat supplier according to instructions, or the heating company reads the meter remotely.
The district heating supplier provides their customers with a follow-up report on heat consumption at least once a year. In many locations, customers can monitor their consumption directly on the heat supplier’s website. The effect of the weather is taken into consideration using the heating degree-day in the comparison of annual consumption figures. The reports usually include adjustment to the weather. If the current consumption differs considerably from the figures for previous years, it is advisable to inspect the adjustments and condition of the equipment.
Your heat supplier will provide additional information on your energy consumption and measurement.
Please inform your district heating supplier if you have carried out any saving measures in your house, if you stop heating your premises for a longer period or if there are any other changes having an effect on energy consumption.
