What is an MVHR System?

MVHR (Mechanical Ventilation with Heat Recovery) systems continuously extract stale, humid air from areas such as kitchens, bathrooms and utility rooms, while supplying fresh, filtered air into living spaces and bedrooms. We install MVHR systems across Bridgend, Port Talbot, Neath, Swansea, and Cardiff, providing a modern ventilation solution for energy-efficient properties.

The system recovers heat from the outgoing air and uses it to warm the incoming air, helping to maintain a consistent indoor temperature without unnecessary heat loss. This makes MVHR systems particularly effective when integrated with central heating systems and modern low-energy designs.

Recent MVHR project: See our MVHR replacement and commissioning case study in Ystradgynlais, where we replaced two failed 26-year-old MVHR units and recommissioned the system properly.

Benefits of MVHR

• Improved indoor air quality
• Reduced condensation and mould
• Lower heat loss compared to traditional ventilation
• Continuous fresh air throughout the property
• Energy-efficient ventilation solution

MVHR systems are particularly effective in modern, well-insulated or airtight homes, as well as extensions and renovation projects where ventilation needs to be carefully managed.
