HEAT RECOVERY

Mechanical Ventilation Heat Recovery

How It Works

An MVHR system is a whole-house ventilation solution that works quietly in the background. It extracts warm, moist air from “wet” rooms such as kitchens, bathrooms & utility areas. This stale air is passed through a high-efficiency heat exchanger before being exhausted outside. Simultaneously, fresh outdoor air is drawn in, filtered & warmed by the heat recovered from the outgoing air. This pre-warmed fresh air is then supplied to your living rooms & bedrooms, creating a balanced, comfortable & energy-efficient environment.

HEAT RECOVERY

Why Your Project Needs MVHR

As modern Donegal homes become more airtight to meet energy efficiency standards, proper ventilation is no longer optional. Our MVHR solutions provide a continuous supply of fresh, filtered air while recovering up to 95% of the heat normally lost through traditional extractors & vents.

Eco-Friendly

By reusing the heat already generated within your home, an MVHR system significantly reduces your heating demand. It is the most effective way to maintain a high BER rating & lower your annual fuel costs in a modern airtight building.

Indoor Air Quality

Our systems feature advanced filtration that removes pollen, dust & fine particulate matter before it enters your living space. This provides a massive health benefit for family members with asthma, hay fever or other respiratory conditions.

As modern Donegal homes become more airtight to meet energy efficiency standards, proper ventilation is no longer optional. Our MVHR solutions provide a continuous supply of fresh, filtered air while recovering up to 95% of the heat normally lost through traditional extractors & vents.

Moisture Control

Donegal’s high humidity levels can lead to condensation & mould growth in energy-efficient homes. MVHR constantly monitors & manages moisture levels, protecting the fabric of your building & ensuring a dry, healthy atmosphere year-round.

Comfort & Security

With a professionally installed MVHR system, there is no need to open windows for ventilation. This keeps your home quiet from outdoor noise & improves security, while the system itself operates at whisper-quiet decibel levels.
