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.
