Government legislation and building requirements require that new homes are built with very low leakage rates, making them more energy-efficient. These air-tight construction methods can result in poor indoor air quality as condensation and pollutants remain trapped inside the home.
The MVHR systems combine supply and extract ventilation in one balanced system with high efficiency and heat recovery, recovering up to 95% heat from your home.

Why Choose a MVHR System
MVHR systems are a year-round, whole-home ventilation solution. They are a proven low-energy and highly efficient ventilation method, typically installed in a utility room.
MVHR is fast becoming the most common method of whole home ventilation for new build properties. Our MRXBOX systems work by combining supply and extract in one unit, moisture-laden, stale air is extracted from ‘wet’ areas, such as kitchens and bathrooms. The heat from this stale air is recovered via a heat exchanger, and this tempered air delivered into the living areas of the home.
The MVHR unit recovers heat with up to 95% efficiency, making it the most effective range currently available. In warmer months when cooling is required to maintain comfort levels, Nuaire’s MVHR Eco range offers 100% automatic bypass with no reduction of airflow. What’s more, MVHR systems provide continuous trickle ventilation to ensure a consistent level of fresh filtered air into the property to maintain adequate indoor air quality.

MVHR Frequently Asked Questions
MVHR systems are the most efficient way of distributing heat and ventilating homes. The system is a much eco-friendlier alternative to intermittent or continuous extract fans, which extract air and heat from the building, potentially wasting energy generated from within the space as air is thrown outside.
With Nuaire MVHR systems, up to 95% of energy is reused and not wasted because the heat exchanger pre-warms fresh air before it enters the space.
MVHR is recommended for all new-build and self-build properties with high air tightness ratings and are the ideal solutions for meeting efficiency and air quality targets.
Nuaire’s MVHR units have been specifically designed with noise and efficiency in mind - and this is essential, as MVHR systems are constantly running, providing filtered air 24 hours a day.
Our MVHR units provide the home with fresh, filtered air all year-round while being as unobtrusive as possible - giving you peace of mind that the air you breathe is as free from dust and allergens.
If you are a consultant looking for MVHR solutions for residential new-build apartments, then Nuaire’s MVHR range includes options that are suitable for wall and ceiling-void installation.
Different system sizes are available that have been designed to ventilate all types of properties sizes and protect against harmful outdoor pollutants.
When you are building a property or changing an existing dwelling, you should comply with building requirements to ensure that the installation of a ventilation system is compliant with the regulations.
All residential buildings throughout the UK and Ireland must conform to the relevant Building Regulations regarding ventilation to reduce excess condensation and damage to structures, as well as ensure indoor pollutants do not build up to harmful levels.
Installing an MVHR system will help you to achieve a high score in SAP, and to comply with Building Regulations Part F & L. Our MVHR systems come with a comprehensive installation guide and our team are also on hand to offer any guidance and advice on installing an MVHR system in your property.
Nuaire’s MVHR systems are designed for straight forward professional installation within UK homes. Installation engineers must be trained and registered to test and commission ventilation systems on new build homes.
It is recommended, wherever possible, that your MVHR unit should be installed in a utility room, close to an external wall on the north elevation, keeping it front-of-mind with good access points. This is generally the cooler part of the home, even during the hotter summer months.
Wherever your MVHR unit is installed, humidity is the most important consideration to bear in mind. A dry room that maintains a fairly consistent temperature throughout the year is ideal, and colder rooms should be avoided. If you are uncertain about where best to position an MVHR system within your home, we recommend that you seek the advice from our sales department.
