Heat Recovery Ventilation Systems

Heat recovery ventilation is also known as mechanical ventilation heat recovery (MVHR) or energy recovery ventilation. It is an evolved ventilation system with a heat recovery unit, which recovers energy between two air sources – one incoming and one outgoing – allowing fresh air to be cooled or heated depending on the demands of the building.

As well as actively providing healthier, cleaner air for inhabitants, Installing an MVHR system also combats issues arising from poor air quality. Airtight buildings with little ventilation often experience high condensation levels, mold, dust mites, and unpleasant smells, which can lead to harmful respiratory conditions.

 By replacing moist, stale air with clean filtered air, a mechanical ventilation system with heat recovery creates much safer living conditions without sacrificing warmth as a traditional mechanical ventilation system would.

How do heat recovery ventilation systems work?

MVHR systems work by continually removing polluted air from each wet room, such as the kitchen and bathrooms, through an extractor valve, boosting when necessary. As it does, the extracted air passes through a heat exchanger. This component transfers the recovered heat to the fresh air being drawn in, which is sent to a supply valve in each habitable room through ducting. Since the polluted air and fresh air travel through different pipes, there’s no risk of cross-contamination between the air flows.

What’s the difference between heat recovery ventilation systems and mechanical ventilation systems?

Traditional mechanical ventilation systems remove wet or polluted air from your property and replace it with cleaner fresh air from outside. While this creates a healthier environment in your home, the constant airflow can make it difficult to retain heat.

Mechanical Ventilation with Heat Recovery (MVHR) systems, on the other hand, retrieve heat from expelled air and transfer it to the new air being drawn in. This allows them to recover up to 95% of the heat that would otherwise be wasted, improving energy efficiency and helping you save on your heating bills, whilst still refreshing your home with clean air.

Benefits of a heat recovery ventilation system

• Keeps your home well-ventilated without lowering temperature
• Saves you money by reducing the cost of heating your property
• Improves air quality for a healthier living environment
• Protects your home and furniture against moisture and pollutants
• Can easily be installed in both new and existing properties
