Optimum makeup water at Skærbæk District Heating

Every year, 27,000 MWh heat is supplied to approximately 1,400 consumers by the district heating plant in Skærbæk, Denmark. Based on the fact, that water quality is crucial for the durability of district heating pipes, installations, and boilers, the utility company has recently improved the quality of the makeup water and circuit water.

Softening, demineralization, and deaeration are the keys to trouble-free operation. The district heating plant has made use of the whole package and fully complies with the current recommendations from the Danish District Heating Association. Download copy here:
