Mechanical Ventilation with Heat Recovery

Understanding Mechanical Ventilation with Heat Recovery (MVHR)

Mechanical Ventilation with Heat Recovery (MVHR) is an innovative system designed to provide homes with continuous, fresh air while efficiently recovering heat from the exhaust air. This technology ensures a healthier indoor environment, reduces energy consumption, and enhances overall comfort.

Understanding Mechanical Ventilation with Heat Recovery (MVHR)

How Does MVHR Work?

MVHR systems operate on a simple yet effective principle. The system extracts stale air from wet rooms like kitchens, bathrooms, and utility spaces. Simultaneously, it draws in fresh air from outside. The heat exchanger within the MVHR unit transfers heat from the outgoing stale air to the incoming fresh air. This process ensures that the home remains warm without losing valuable heat, thereby conserving energy.

Key Benefits of MVHR?

Energy Efficiency - MVHR systems significantly reduce the need for additional heating by recycling up to 95% of the heat from the outgoing air.

Improved Air Quality - Regularly filtered fresh air helps reduce indoor pollutants, allergens, and humidity, enhancing indoor air quality.

Cost Saving - By maintaining a consistent indoor temperature and reducing the need for heating, MVHR systems can lower energy bills.

Environmental Impact - Reduced energy consumption translates to a smaller carbon footprint, contributing to a greener environment.

Enhanced Comfort - Consistent and balanced ventilation ensures an even temperature distribution throughout the home, eliminating cold spots.

MVHR System Components

Heat Recovery Unit - The core component that houses the heat exchanger and fans.

Air Ducts - Network of ducts that transport stale air out and bring fresh air in.

Filters - Essential for removing dust, pollen, and other pollutants from the incoming air.

Controllers - Allow homeowners to adjust settings and monitor the system's performance.

Installation & Maintenance

Installation and Maintenance

Professional Installation

For optimal performance, professional installation is crucial. Certified installers will ensure the system is correctly integrated into your home’s structure, effectively balancing airflows and maximizing heat recovery.

Professional Installation

Regular Maintenance

To maintain efficiency, MVHR systems require regular maintenance. This includes:

Regular Maintenance

To maintain efficiency, MVHR systems require regular maintenance. This includes:

Cleaning or replacing filters every six months to a year.

Checking the heat exchanger annually.

Ensuring ducts remain clear of obstructions.

Routine maintenance will prolong the life of your MVHR system and ensure it operates at peak efficiency.

Is MVHR Right for your Home?

MVHR systems are suitable for a wide range of homes, from new builds to retrofits in existing properties. They are particularly beneficial in airtight, well-insulated homes where natural ventilation is minimal. If you are renovating or building a new home, considering an MVHR system could be a smart investment for long-term comfort and savings.
