Maintaining excellent indoor air quality has recently become an increased focus among homeowners and business owners alike. Decentralised mechanical ventilation with heat recovery (MVHR) is one technology used to achieve cleaner air in buildings. This article will examine this system’s inner workings and benefits.

What Is Decentralised MVHR?

Decentralised MVHR technology enhances indoor air quality by extracting unfiltered, stale air from rooms, recovering its heat for reuse in that room, and then returning fresh, uncontaminated air. Decentralised MVHR units are typically installed in individual rooms to provide precise control.

How Does Decentralised MVHR Work?

Decentralised MVHR systems are compact and simple to set up. Their two primary components – an exhaust fan and an intake fan – work in unison to deliver fresh, clean air as scheduled. As follows:


An exhaust fan draws in air from within a room to capture any heat energy present and move it onto the heat exchanger in the unit for further use.

Heat Exchanger:

A heat exchanger is an indispensable element of MVHR systems, transporting captured heat energy from expelled air back into preheating fresh air entering your facility, thus warming it before entering.


An intake fan brings prewarmed and filtered air back into the room for heating or filtering to maintain fresh and comfortable indoor air quality.

Benefits of Decentralised MVHR

Improvement in Indoor Air Quality: Decentralised MVHR systems continuously supply fresh, filtered air that filters away pollutants, allergens, and humidity, resulting in healthier living spaces indoors.

Energy Efficiency: Decentralised MVHR units can save heating costs and increase energy efficiency by recovering heat from air that has been exhausted through exhaust ducts. They also increase heating performance.

Quiet Operation: These units have been specially engineered to operate quietly and cause no interference with daily activities.

Decentralised MVHR Units: Offer Individual Room Control Unlike centralized systems, Decentralised MVHR units enable individual room control, enabling you to customize ventilation according to your specifications and, more precisely, meet ventilation needs.

Easy Installation: Installation can often be straightforward, making this system attractive for retrofit and new construction projects.

Applications of Decentralised MVHR

Decentralised MVHR units can be applied in many environments:

Residential Buildings

Decentralised MVHR systems in homes ensure fresh air reaches every room for improved indoor air quality and contribute to creating a healthier living space, which is particularly advantageous in houses with compact designs. These MVHR units may help save on costs!

Commеrcial Spacеs:

Decentralised MVHR units can create an ideal working and customer environment in offices, retail stores, and restaurants while maintaining productivity and comfort for employees and customers.

Hospitals and Healthcare Facilities

Clean air is key in healthcare environments, and Decentralised MVHR units can assist in creating safe spaces where it matters most.

Education Institutions

Air circulation can dramatically enhance the educational environments at schools and universities.


Hotel guests want their experience to be enjoyable and healthy; Decentralised MVHR provides the ability to deliver on both fronts.

Choosing the Right Dеcеntralizеd MVHR System

Your goal should be making the smartest possible selection when choosing a decentralized Mechanical Ventilation with Heat Recovery (MVHR) system for home or office use. Hence, this guide provides helpful steps written in simple language that include practical solutions.

1. Analysing Your Needs

Deliberating over your space and needs is the first step toward successful ventilation system installation. This information will determine what size system best meets them, from commercial properties to homes.

2. Explore Your Options:

Research all four Decentralised MVHR system types available – Heat-only (heat-cool), Heat-pump, and Dedicated Outdoor Air Systems (DOAS). Each has unique benefits that best meet your requirements. Choose the system that best matches up with what suits you!

3. Calculate Airflow Requirements:

Determine airflow needs according to room size, number of occupants, and air changes per minute to achieve optimal ventilation conditions in your space. It will guarantee proper ventilation conditions are in place.

4. Budget Considerations

Assemble your budget, including installation and maintenance fees. Although Decentralised MVHR might cost more initially, they’ll save money overall in the long run.

5. Energy Efficiency

To save on heating and cooling bills, opt for products with higher energy recovery rates. This way, you’ll reduce costs.

6. Installation:

Ensuring a swift and cost-efficient installation process is imperative; the complexity of ductwork requirements for certain systems may impact both installation time and costs.

7. Noise Levels:

Inspect the system’s sound levels to assess whether they meet residential setting noise regulations; systems with lower sound output are ideal in these settings.

8. Installation and Placement:

Install the MVHR unit. It should be strategically located to ensure fresh air is distributed effectively.

Follow these steps when selecting Decentralised MVHR systems to help make an informed choice that aligns with your energy goals, budget, and needs. Finding an ideal system is crucial.
