FLUX HR Continuous Running Alternate Flow Heat Recovery Fan
FLUX HR Continuous Running Alternate Flow Heat Recovery Fan is a continuously running, low energy, ultra quiet, alternate flow supply and extract fan with heat retention for use in habitable areas such as living rooms, bedrooms, dining rooms, basements and hallways. The unit helps a room “breathe” and reduces indoor air pollutants and humidity levels.
The unit is ideal for tackling problems associated with condensation dampness such as mould growth. The unit is not designed for use in ‘wet areas’ such as bathrooms or kitchens.
Every 70 seconds the unit alternates between supply and extract fan modes. When in extract mode the unit’s high efficiency ceramic heat exchanger collects and retains heat from the extracted air. The majority of this heat is then transferred to the incoming air during supply mode.
This method of operation avoids the short circuiting of air that can often happen with conventional single room heat recovery units, resulting in much more effective room ventilation.
Units can also be set to work in harmony with each other e.g. when a unit in one room is extracting air another unit in another room can be set to supply air. This can greatly enhance cross ventilation and ventilation effectiveness in a home.
The technical team at Alliance Remedial Supplies feel the main benefits to the FLUX HR100 Continuous Running Alternate Flow Heat Recovery Fan are its neat and discreet internal panel. It’s ultra low running sound which we can vouch is imperceptible. The ease of installation with no requirement to install a separate humidity sensor box and its annual running cost of only £3.15 a year*.
However, its limitations are; it cannot be ducted more than a meter away and no bends can be introduced. Not suitable for bigger volume areas such as Kitchen/Dining rooms or wet rooms such as bathrooms and utility rooms.
The FLUX HR 100 is ideal for small to mid size bedrooms and living rooms with a cubic volume of up to 40m³ which typically would be a footprint of around 4.5mtrs x 4mtrs with a ceiling height of 2.2mtrs. If you want to ventilate a room with a bigger footprint we recommend the FLUX HR-150 which will ventilate up to 70m³.
If you install two fans in one property we recommend the installation of a Controller to select on/off, speed selection and extract or supply modes.
