Choosing an MCS-certified installer guarantees a high-quality renewable energy system. MCS certification signifies adherence to stringent performance and safety standards, verifying both equipment quality and installer competence. This rigorous vetting process ensures installers demonstrate proven compliance with MCS standards, providing assurance in their technical expertise and the reliability of your installation.
MECHANICAL VENTILATION & HEAT RECOVERY
Fresh, Clean, Healthy air for Comfortable Living
The Smarter Way to Ventilate a Building
Modern homes are built to be increasingly airtight, improving energy efficiency but reducing natural ventilation.
Without adequate ventilation, moisture, pollutants and stale air can build up indoors, leading to condensation, poor air quality and discomfort.
Mechanical Ventilation with Heat Recovery (MVHR) provides a continuous supply of fresh, filtered air while extracting moisture and pollutants from wet rooms. At the same time, heat from outgoing air is recovered and transferred to the incoming air supply.
Fresh air without wasting heat.
Fresh, Filtered Air
Continuously supplies fresh outdoor air while filtering out dust, pollen and airborne pollutants, helping create a healthier indoor environment.
Heat Recovery & Energy Savings
Recovers heat from outgoing stale air and transfers it to incoming fresh air, reducing ventilation heat losses and supporting lower energy consumption.
Moisture & Condensation Control
Removes excess moisture from kitchens, bathrooms and living spaces, helping to reduce condensation, damp and mould growth.
Why MVHR Feels Different
Traditional Ventilation
Warm stale air leaves the building.
Cold fresh air entering the building.
Mechanical Ventilation and Heat Recovery (MVHR)
Stale air extracted from wet rooms.
Fresh filtered air supplied to living spaces.
Frequently Asked Questions (FAQ's)
How does MVHR work?
MVHR extracts stale air from kitchens, bathrooms and utility rooms while supplying fresh, filtered air to living rooms and bedrooms. Heat from the outgoing air is transferred to the incoming air through a highly efficient heat exchanger.
Does MVHR save energy?
Yes. By recovering heat that would otherwise be lost through ventilation, MVHR systems can significantly reduce ventilation heat losses.
Does MVHR help with condensation?
Yes. Continuous extraction of moist air helps reduce condensation, damp and mould growth.
Is MVHR suitable for existing homes?
MVHR works best in airtight properties but can also be incorporated into renovation projects where appropriate duct routes can be installed.
Does MVHR remove pollen and pollutants?
Yes. Filters within the system help remove dust, pollen and airborne pollutants from incoming air.
How often do filters need changing?
Typically every 6–12 months, depending on the property location and manufacturer recommendations.
Is MVHR noisy?
A properly designed and commissioned MVHR system operates very quietly and is often barely noticeable.
Can MVHR work with heat pumps?
Absolutely. MVHR complements heat pump installations by reducing heat losses and improving overall building efficiency.
Do I still need to open windows if I have MVHR?
No. An MVHR system is designed to provide continuous fresh air throughout the building without relying on open windows. While windows can still be opened whenever desired, they are generally not needed for day-to-day ventilation.
How efficient are modern MVHR systems?
Modern MVHR units can typically recover between 80% and 95% of the heat from extracted air, helping to reduce ventilation heat losses while maintaining a constant supply of fresh air.
