Most of the systems realised at the moment are bi- or multi-valent. For example, the basic load can be covered with wastewater heat, and district heating, gas or/and CHP plants can be used to cover peak loads. Our heat exchanger plants are always aligned to what is called the minimum dry weather flow, i.e. the moment when the least wastewater is flowing through the sewer. This means that the reliable performance of the systems is guaranteed on a highly conservative basis.
Another option is the use of heating networks. Energy from wastewater is a highly attractive green energy source for district or local heating, whether this is a cold or warm network.
