Heating homes sustainably

 

The heat is supplied to the homes of the end customers for heating and hot water through district heating pipelines. This takes place primarily via underground pipe systems. The water in the pipes is heated and isolated until it reaches the space to be heated. The heat is not produced on-site at the end customer through oil heating or heat pumps, but, in general, by burning wood (e.g. pellets or wood chips) in a central furnace. The heat is thus generated exclusively from domestic, renewable, CO2-neutral raw materials. Waste heat, e.g. from factories and sewage treatment plants, can also be used. Since mainly renewable energy sources are used and the waste heat is often a by-product, district heating is ecological and sustainable.
