Advanced Ventilation with Energy Savings in Mind

At Ventilair Group, we supply high-performance heat recovery ventilators that deliver fresh, filtered air while retaining valuable indoor warmth.

Perfect for both new builds and renovations, our systems support a healthier, more energy-efficient indoor environment in homes, apartments, and commercial properties.We distribute a carefully selected range of units from trusted European manufacturers — including the Pax Eos, which we offer exclusively in Spain and Portugal.

What Is a Heat Recovery Ventilator?

A heat recovery ventilator (HRV) is a mechanical ventilation system that extracts stale indoor air and replaces it with fresh outdoor air — all while retaining up to 80–85% of the heat from the air being expelled.

Instead of wasting energy heating incoming air, an HRV transfers warmth from the outgoing stream to the incoming one. This dramatically reduces heat loss, lowers energy bills, and helps regulate indoor humidity.

Why Install a Heat Recovery Unit?

Whether you’re dealing with poor air circulation, excess moisture, or rising energy costs, a heat recovery ventilator offers a smart, long-term solution:

• Delivers continuous, balanced ventilation with little to no user input
• Improves indoor air quality by removing CO₂, allergens, and odours
• Reduces condensation and damp — especially useful in well-insulated or airtight homes
• Minimizes heat loss with efficiency ratings up to 85%
• Lowers HVAC energy consumption year-round

We offer both centralized and decentralized heat recovery units to suit different property layouts and budgets. Many systems are designed for wireless app control, offer modular expandability, and support quiet, low-energy operation.
