Information about the district heating network

If the heating and/or hot water supply of a property is connected to a district heating network, the annual greenhouse gas emissions and the primary energy factor of the district heating network must also be stated in the heating cost statement in accordance with Section 6a of the Heating Costs Ordinance. The data is provided by the district heating supplier.

Immodio asks for the information on the district heating network in the operating cost statement if you have stored "district heating" as an energy source in the property or unit under "Equipment" for heating and/or hot water supply.

Where does this information come from?

The greenhouse gas emissions and the primary energy factor of the district heating network are provided by the respective district heating supplier and do not have to be calculated by the district heating supplier itself.

You can usually find the values:

• on the annual statement of the district heating supplier

• on the website of the district heating supplier

If you do not have the information, you can request it directly from the supplier.

What do these terms mean?

Greenhouse gas emissions

Greenhouse gas emissions indicate how many greenhouse gases are produced when generating one kilowatt hour of district heating. The specification is usually given in grams of CO₂ equivalent per kilowatt hour (g CO₂e/kWh). The lower the value, the more climate-friendly the district heating is generated.

Example:

• District heating network A: 45 g CO₂e/kWh

• District heating network B: 180 g CO₂e/kWh

Primary energy factor

The primary energy factor (PEF) describes how much primary energy is needed to provide one kilowatt hour of district heating. Among other things, the extraction of energy sources, transport, conversion and distribution losses are taken into account. The lower the primary energy factor, the more efficiently the district heating network works. Example:

• District heating network A: 0.35 – A low primary energy factor shows that district heating is generated particularly efficiently. The heat comes mainly from renewable energies or waste heat, so that only little primary energy is required and there are few line losses.

• District heating network B: 1.10 – A high primary energy factor means that more primary energy must be used to provide district heating. This is often the case with district heating networks with a higher proportion of fossil fuels or greater energy losses.
