Making heat comfortable
Around 80 per cent of a German household's energy requirements are used to heat living spaces and provide hot water. There are various ways of providing the energy required for this. District heating is a particularly sensible option. It offers many advantages over individual heat generation in many individual buildings.
Our heating tariffs
District heating in Giessen means: we generate thermal energy highly efficiently and in many plants distributed throughout the city. We supply this energy in the form of hot water to almost 2,800 buildings - from single-family homes to industrial plants - via an optimally insulated pipe network that is over 200 kilometres long. As with central heating in a typical residential building, there are also two pipes in the district heating network: higher temperatures prevail in the flow pipe. The heat reaches the customers through this pipe. The return pipe collects the water that has cooled down in the many buildings and returns it to a heat generator.
HELLO DISTRICT HEATING
Are you looking for a heating solution that is sustainable, efficient and simple? Then we have good news for you: with the option of connecting to our district heating network, this solution is practically on your doorstep. Get to know the good feeling of a carefree and secure heat supply now and say hello to district heating from your neighbourhood.
Those who say hello to district heating also say yes to efficiency. This starts with the generation of district heating, as it requires much less energy to produce than the many small heating systems in each individual house. District heating also eliminates the need to have your own heating system and worry about buying fuel.
Discover the advantages of heating with district heating from SWG. It offers you many possibilities and is particularly impressive in its practical application.
This brings the warmth to your home.
District heating means that heat is generated in one or more heating (power) plants and transported directly to customers in the form of hot water via a pipework system.
We generate most of our district heating using the principle of combined heat and power (CHP). This means that heat and electricity are generated simultaneously in a single plant. This technology is particularly efficient and environmentally friendly. We now operate more than 167 CHP plants spread throughout the city of Giessen and the surrounding area.
We transport the heat from these many decentralised generation plants to our customers in the form of hot water via a well-insulated pipeline system. There, the house connection links the district heating network with the transfer station in the house. In the transfer station, the hot district heating water heats the heating and service water via a heat exchanger, which is then fed into the existing heating system with the help of a circulation pump. Once the district heating water has cooled down again, it is pumped back to the generation plant, where it is reheated and the cycle begins again.
Primary energy factor
What is that anyway?
The primary energy factor indicates how much primary energy is required for a certain amount of final energy, depending on the energy source. The primary energy factor therefore takes into account the energy loss during the extraction, conversion and distribution of an energy source. The more environmentally friendly an energy source, the lower the primary energy factor and therefore the lower theCO2 emissions.
Permissible replacement measure for the use of renewable energies according to GEG
The new Building Energy Act (GEG) came into force on 1 November 2020. It replaces the previous Energy Saving Act (EnEG), the previous Energy Saving Ordinance (EnEV) and the previous Renewable Energies Heat Act (EEWärmeG) and brings their regulations together in one law. Like the previous Energy Saving Act for Buildings, the new GEG includes requirements for the energy quality of buildings and the use of renewable energies in buildings.
The GEG stipulates that the heating and cooling energy requirements of new buildings must be covered at least in part by the use of renewable energies. Alternatively, climate-friendly alternative measures such as district heating can be used. The prerequisite is that the district heating fulfils certain criteria, for example at least 50% of the heat can come from highly efficient combined heat and power plants. Heat from SWG fully fulfils this criterion. District heating from SWG is therefore considered a substitute measure within the meaning of the GEG.
