Discover the Power of MVHR Units for a Fresh Home Atmosphere

Creating a healthy indoor environment is simple with Mechanical Ventilation with Heat Recovery (MVHR) systems. In this comprehensive guide, we'll delve into MVHR units, making them the heart of our discussion.

Understanding MVHR Units

MVHR units are the foundation of effective home ventilation. With over 50 units available, finding the perfect match is easy. Our team can guide you, or you can use our simple product selector tool.

Choosing the Right System

Different manufacturers have unique strengths. Vent Axia offers reliability, Airflow Adroit provides interactive control, Domus gives excellent value, and Nuaire suits straightforward projects.

Understanding Heat Recovery

MVHR systems use Counterflow heat exchangers for energy efficiency and to prevent air streams from mixing. Rotary heat exchangers, better for commercial spaces, add some humidity—less fitting for homes.

Determining Airflow Requirements

Customizing your MVHR system according to the requirements of your home is essential. For smaller homes, ensure the unit can handle the combined airflow of wet rooms. Larger homes should consider ventilation rates based on usable floor area. It might sound technical, but it's essential for effective home ventilation.

Choosing the Right Size

Selecting the right-sized MVHR unit is key for efficiency and noise reduction. Aim for a unit that operates at less than 70% of total output for optimal performance. Running a unit at maximum capacity not only increases noise but also consumes more energy.

Efficiency Matters

Efficiency is crucial for MVHR systems. Search for units with an Energy Performance Rating (EPR) of A or higher. Lower Specific Fan Power (SFP) is better.

Two Units Are Better Than One

For larger properties, consider deploying two MVHR units. This not only enhances system efficiency and heat recovery but also ensures a quieter environment.

Ducting: The Unsung Hero

The success of your MVHR system depends on the quality of the ductwork. We recommend radial ducting for quiet and efficient performance. Don't underestimate the impact of proper ducting on overall system effectiveness.

In Summary

This guide simplifies MVHR units, making them the center of your journey toward a healthier home. With the right MVHR unit, you can achieve optimal ventilation and make it a reality for your needs. MVHR ensures comfort and efficiency for easy breathing.
