A key aspect of a well planned, low energy MVHR system is the ducting type, design and the quality of installation.
- Best practice is to use larger diameter, 125mm diameter branch lines and up to 250mm diameter main lines, which can carry the necessary high volumes of air at low velocity (depending on size of system).
- Rigid, large diameter ducting is the preferred choice to provide a smooth flow of air, causing less noise (from both fans and air turbulence) and costs less to run. Foil backed insulated ducting in a cold space is essential to retain high heat efficiency.
- Carefully considering the design and choice of installation materials ensures your MVHR system delivers the correct ventilation rate and heat efficiency to your home.
- Manufactured in high quality steel our modern Supply & Extract Valves are designed to not produce down draft, ensuring a comfortable indoor climate.
