More than an extractor fan! Intelligent ventilation with heat recovery

The ideal enhancement to your energy-saving measures around the house

Regular ventilation keeps you and your building healthy. It is particularly important that you consider this aspect in heat-insulated houses with well-sealed windows and doors. However: Heat and expensive thermal energy are lost when the windows are open. The solution: Dorset Insulation offers fresh air heat exchanger for innovative ventilation. In this system, the waste air from the room warms the incoming fresh air as it flows out.



Keeps heat in the house


  • Continuous basic ventilation
    in the living room, bedroom and bathroom, etc.
  • Keeps you and your building healthy:
    no damp, no mould
  • Easy to install 
  • Reduces condensation
  • Helps prevent moulding




How does it work?

The system will extract the warm, moist air from rooms such as kitchens and bathrooms etc. This is done through a concealed duct system.air-ventilation-home-office

The air is passed through a heat exchanger then ducted outside. Fresh air from outside is drawn in and passed through the heat exchanger, which warms it, and it’s then ducted to the living rooms and bedrooms.
