In Vedbæk, in the north of Denmark, where elegant private villas meet the chilly sea breeze, the owner of a coastal residence was searching for a way to modernise his home’s heating system. The building is heated by radiators that require a stable water temperature of up to 65 °C. The existing system could no longer deliver the required reliability or energy efficiency, and the biggest challenge was finding a technological upgrade that would not compromise the architecture or visual identity of the estate. The investor’s wish: a heating system that operates discreetly — both in terms of noise and visual impact.
