Mechanical Ventilation with Heat Recovery (MVHR)
Modern homes are becoming increasingly airtight to improve energy efficiency, but this can trap moisture, pollutants, and stale air inside.
Our Mechanical Ventilation with Heat Recovery (MVHR) systems solve this problem by continuously extracting damp, humid air from kitchens, bathrooms, and utility rooms while supplying fresh, filtered air into living spaces.
The clever part? As stale air is extracted, up to 95% of the heat is recovered and transferred to the incoming fresh air.
This means you enjoy excellent indoor air quality and significantly reduced condensation and mold risk — all while keeping your heating bills low.
Key Benefits:
- Dramatically reduces condensation and mold growth
- Improves indoor air quality by removing pollutants and allergens
- Recovers up to 95% of heat from extracted air
- Helps maintain optimal humidity levels (40-60%)
- Works silently and efficiently in modern airtight homes
- Supports a healthier living environment for the whole family
Mechanical Ventilation with Heat Recovery (MVHR)
In today’s well-insulated and airtight homes, natural airflow is often insufficient to maintain good indoor air quality. This is where Mechanical Ventilation with Heat Recovery (MVHR) makes a significant difference.
MVHR is a whole-house ventilation system that continuously extracts stale, humid air from wet rooms such as kitchens and bathrooms, while simultaneously supplying fresh, filtered air into living areas. As the outgoing air passes through a highly efficient heat exchanger, up to 95% of the heat is recovered and transferred to the incoming fresh air.
Benefits of MVHR:
- Dramatically reduces condensation and the risk of mold growth
- Maintains optimal indoor humidity levels
- Provides continuous fresh, filtered air – removing pollutants, allergens, and CO₂
- Significantly improves energy efficiency by recovering heat
- Creates a healthier, more comfortable living environment
- Operates quietly and efficiently without drafts
- Helps your home comply with Approved Document F, L & O
At Healthy Indoor Air UK, we are fully trained and approved in MVHR systems. We offer expert design, installation, servicing, and commissioning of high-quality MVHR units from leading manufacturers including Vent-Axia, Daikin, and Airflow.
Whether you’re building a new home or retrofitting an existing property, our MVHR solutions deliver long-term protection against damp and mold while ensuring excellent indoor air quality for you and your family.
Modern airtight homes make natural ventilation unreliable.
That’s why mechanical extraction (often integrated with MVHR systems) is now essential to comply with Part F.
It continuously removes stale, moist air at source and replaces it with fresh filtered air — dramatically reducing the risk of damp and mold while keeping your home healthy and energy-efficient.
At Healthy Indoor Air UK, all our MVHR installations and extraction systems are fully designed and commissioned to meet or exceed the requirements of Approved Document Part F.
Approved Document Part F – Ventilation Requirements
Building Regulations Approved Document Part F sets the legal standards for ventilation in all new homes and major renovations in England and Wales.
It ensures that dwellings have adequate means of ventilation to maintain good indoor air quality and control moisture.
One of the most critical aspects of Part F is effective extraction in high-moisture areas such as kitchens, bathrooms, utility rooms, and WCs. Without proper extraction, humid air, cooking fumes, steam, and pollutants can build up, leading to:
- Condensation on walls and windows
- Black spot mold growth
- Poor indoor air quality
- Increased risk of respiratory issues and allergies
- Long-term damage to the fabric of the building
