Introduction
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.
MVHR (Mechanical Ventilation Heat Recovery) offers year-round ventilation that will improve indoor air quality whilst recovering the heat that would otherwise be lost outside.

How Does MVHR Work
A proven low-energy and highly efficient ventilation method, MVHR is fast becoming the most common method of whole home ventilation for new build properties.
MVHR 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. Nuaire’s MVHR range recovers heat at 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% bypass with no loss of resistance.
