Are the systems planned and operated on a monovalent or a bi-/multivalent basis?

Most of the systems we realize today are bi- or multivalent. This means, for example, that the base load can be covered with wastewater heat, while peak loads are covered by district heating, gas or/and CHP plants. Our heat exchanger systems are always aligned with the lowest possible dry weather flow, which is the lowest level of wastewater that can flow through the pipeline. This ensures that the systems always perform reliably.
A further possible application of wastewater heat is feeding it into heating networks. Energy from wastewater is an appealing green energy source for district or local heating, whether this is a cold or warm network. We have already realized some projects of that kind.
