EvoFlat leads to huge energy savings in housing association
"Alternative system solutions were evaluated, but flat stations was the best solution in this project, where an old district heating system needed to be modernized and where there was a demand for individual meters in each apartment."
A recently installed EvoFlat heating and hot water system in 324 apartments belonging to SAB, a co-operative housing association in the southern Danish town of Sønderborg, has led to average annual energy savings of an estimated 30% per apartment.
The result has mainly been achieved by installing a two-pipe system with Danfoss flat stations – EvoFlat – for district heating. In the original one-pipe system, installed in 1964, water was heated in central substations placed in a boiler room under the block of apartments. Today, water is heated locally in each of the flat stations and residents can see exactly how much energy they spend.
