Mechanical ventilation heat recovery systems, or MVHRs, are ventilation systems that reuse and redistribute air. Rigid ducting extracts stale air from sources such as your kitchen, wet rooms, and utility rooms, removing the heat from this extracted air and transferring it to fresh air that has been taken in from outside the property through a heat exchanger. MVHR units have become a popular choice for modern homes due to the continuous supply of fresh air that they are able to provide, whilst also being highly energy efficient and inexpensive to run. If you are considering mechanical ventilation with heat recovery for your property, take a look at some of the benefits you could see.

What benefits do MVHR systems have?

MVHR units have been favoured over traditional heating methods for a number of reasons, including:

Air quality

Because they are constantly taking in fresh air from outside and removing any air from rooms where the indoor air quality will not be as good, you will have consistently clean air flowing throughout your property when you choose an MVHR. Because this used air is constantly being removed, this also removes lingering smells and bad odours so that you are breathing in fresh filtered air all the time in all areas of your property. This can also benefit you if you suffer from allergies, as this filtered air coming in will have all pollen removed. An MVHR unit can also filter out any pollutants or outside smells that you will not want to circulate around your home. Having consistently clean and fresh air circulated around your home can have a positive impact on your general health and wellbeing.

Energy efficiency

Because of their energy efficiency, heat recovery units are the best option for many homeowners and business owners. Most systems are powered by small motors, which use minimal engines and have running costs that are a fraction of what it would cost to use traditional heating methods. This will have a noticeable impact on your energy bill at the end of the month. The fact that these systems retain the existing heat from your home and transfer it into fresh air means that minimal heat is lost and you will not need your radiators turned on constantly to heat each room. The energy savings you will see will be greater than any other method of heating.


In the warmer months of the year, you do not have to worry about leaving windows open to create airflow whilst you are out or asleep. An MVHR works by creating a constant temperature and circulating fresh air to keep your home well ventilated, so you will not need to leave windows and doors open to air out each room.


Because mechanical ventilation heat recovery systems are suitable for both heating and ventilating your home, this eliminates the need for devices that may only do one job. For example, extractor fans in your bathroom or trickle vents on your windows are no longer needed, as the MVHR unit will remove this used air and recirculate fresh air instead.

An MVHR unit is the perfect system to keep your property ventilated and at a comfortable temperature all year round.
