Invitation to external partners to be part of a test bed for Low Temperature District Heating

Kraftringen is building a unique low temperature district heating network. We invite external partners to demonstrate various innovative products and practises in this grid. The test bed is under development, but we are open for ideas from external participants. Some of the current ideas regard: Production: Software for heat storage purposes, optimisation of the production […]

System solutions for multifamily houses and tertiary buildings

The pipe heat losses in the circulation of domestic hot water (DHW) can be high in comparison to the demand and use of DHW. Flat stations can be used in order to potentially lower these heat losses. Kraftringen, COWI A/S and Cetetherm have looked closer on solutions with flat stations in buildings with low district […]

Solutions for avoiding risk of Legionella

Low temperatures in domestic hot water systems increases the risk of growth of Legionella bacteria which if inhaled can cause Pontiac fever or Legionnaires’ disease. Lund University, Kraftringen and COWI have worked on a report that investigates solutions for avoiding risk of Legionella when using LTDH. Kerstin Sernhed from Lund University (Dept. of Energy Sciences) introduces the report.
