DUKA One
How much does a DUKA One need to run?
DUKA One is a ventilation solution that must run and ventilate 24 hours a day. For 70 seconds, the unit sucks out used and moist air, storing heat in the unit's ceramic core. After 70 seconds, the unit's blowing direction is reversed and the unit sends in fresh air that is heated by the ceramic core. This constantly changes the air, ventilating away particles and moisture and saving you money on your heating bills as the heat in your home is recycled. DUKA One can be installed directly in the outer wall and can be installed wherever there is a need for ventilation.
How much does it cost to run?
You may think that the unit shouldn't run constantly as you're not in your holiday home every day, but constant operation provides a much better indoor climate, fewer particles, and not least reduces moisture and radon.
