Increased water temperatures

Investigations on the causes of increased water temperatures in the drinking water network and identification of countermeasures

Visualisation of water temperatures in a network area

Increased water temperatures in the drinking water network already pose a challenge for water supply companies. The objective of the research project is to develop the basis for various fields of action for dealing with the problem of increased water temperatures in the distribution system on the basis of extensive investigations.

Increased water temperatures in the drinking water network are already a reality, although further increase is expected in the future. This results in questions such as:

Under which boundary conditions is the occurrence of increased water temperatures in the supply system to be expected?

Which measures are basically suitable for stabilising or reducing the water temperature in the supply system?

Which tools can be used to model the water temperature in the distribution system?

Which effect can be achieved by which measures to avoid increased temperatures under practical conditions?

What effect do temporarily increased temperatures have on the service life and function of components of the drinking water supply system?

How will temperature problems develop in the future and what are the consequences?

Within the scope of the DVGW research project, the complex processes of drinking water heating are to be deciphered and the future development predicted so that consequences for fields of action such as network operation, network planning, regulation, public relations work etc. can be derived.
