The FOS/BOS Weilheim will be heated with district heating in the future;
that saves 78 percent CO2.
The district committee unanimously followed the recommendation of the administration in cooperation with the Energiewende Oberland EWO and decided to convert the energy supply to district heating in combination with the existing gas boiler.
Weilheim – The state FOS/BOS Weilheim building is currently heated with natural gas.
Gas consumption is around 1,300 megawatt hours per year, which corresponds to CO2 emissions of around 260 tonnes per year.
For this reason, the school's heat supply should be converted and connected to the city of Weilheim's district heating system.
90 percent of the district heating connection is via renewable heat
In the future, 90 percent of the heat supply and thus base load coverage will come from renewable district heating;
The ten percent peak load is covered with the existing gas boiler.
There were three alternatives to choose from: a pellet heating system to cover the base load combined with a gas boiler for peak load (co-criterion: structural situation on site) - a pure district heating supply (co-criterion: basic fee that is too high) - a heat pump hybrid heating system (co-criterion: basic fee that is too high). -Criteria: excessive power consumption).
Although district heating is currently slightly more expensive, the expected costs are subject to significantly fewer fluctuations than the price of gas, on which an increasing CO2 tax is also due.
By saving over 1,000 megawatt hours of natural gas, the district is also making a significant contribution to climate protection if the renewable energy mix for district heating production comes as planned.
The CO2 emissions were reduced by 78 percent compared to pure gas heating.
Since the district heating pipes are already in place - the connection is planned at the fire station - the FOS/BOS could be heated with district heating as early as next winter.
Now we just have to think about better use of waste heat within the school, where, according to EWO, an additional 15 percent could be saved.
