Task

• In 2010, this farmhouse was converted into a luxury residential villa. The 2,300m3 building has a low-temperature system with 1,600 m of underfloor heating. The system has two heat pumps and two underfloor heating manifolds with eight groups each. The system is used for both heating and cooling.

• Originally, in cold periods (< 5°C), a number of rooms did not heat up; one room in particular was affected. To enable this room to be heated, an additional electric radiator was installed in it.
