Air circulation between rooms


Transfer heat between rooms

Unnecessarily warm in the kitchen and bedroom? Too cold in the living room and the recreation room? This is a far more common problem than you might think. Far too many buildings are needlessly faced with high energy costs – for both heating and cooling. There is however a solution that is neither overly expensive nor particularly difficult to fix yourself.

We often talk about supply and exhaust air, while sometimes overlooking the air that circulates between rooms. If the air is unable to circulate between rooms your ventilation will not function, sometimes leading to poor air quality in a room despite having installed an air vent or bathroom fan. The problem of poor air circulation can often be solved by installing a duct fan or air transfer unit.


Transfer air between rooms
Increasing numbers of people are installing a stove or heat pump to supplement their heating systems. The problem with this approach is that the heat often remains in one room. One solution is to install a heat transfer unit to distribute excess heat to adjoining rooms.


Distribute excess heat from one room to another.


It is often not a matter of adding more cooling or heating but rather of distributing it in a more efficient manner. Better ventilation is only one way to get more out of every penny you spend on heating. 

By transferring heat between several rooms, you equalise temperature differences and
create a comfortable indoor climate throughout the home.


By installing one of Fresh’s heat transfer units or duct fans you can benefit from the heat in the home before it is extracted and replaced with fresh air. In this way, you can take advantage of up to 70% of the heat. Select the product that best suits your needs from the above selection and learn more about how you can save money and simultaneously improve your indoor climate.

Installation tips
• Use ventilation ducts and duct fans if you need to transfer heat between several spaces in your home.
• Soundproof on both sides of duct fans or at every supply and exhaust vent 
• Always insulate ducts in cold spaces to avoid condensation.
