Mechanical Ventilation Heat Recovery

 As homes become increasingly airtight through efficiency measures such as insulation, draught-proofing and double-glazed windows, a lack of natural ventilation means that moisture created from everyday activities such as cooking, washing and even breathing remains in the home. With nowhere to go, this moisture collects on cold surfaces such as windows and outside walls and causes condensation, damp and mould growth, all of which contribute to poor indoor air quality.

Benefits of MVHR 

• Eliminates condensation and mould that can cause cosmetic and structural damage
• Significantly improves indoor air quality – extracts moist and polluted air and filters incoming fresh air to eliminate indoor and outdoor pollutants in homes
• Extremely efficient – up to 91% of heat from extracted air can be retained and transferred to incoming fresh air
• Requires minimal maintenance and user control – once installed and calibrated, MVHR units automatically boost when they detect changes in humidity

MVHR can be designed and installed to most new build and some existing properties.

We use PVC and metal rigid duct or a flexible radial ductwork depending on the building construction.

With manufacturers such as Vent Axia, Nuaire and Zehnder we can offer a tailored design with full installation and commissioning.
