MVHR (Mechanical Ventilation with Heat Recovery) is a whole-house ventilation system that continuously extracts stale, moist air from inside your home and replaces it with fresh, filtered air from outside—while retaining up to 90% of the heat.

This means you enjoy fresh air year-round without heat loss, making it ideal for well-insulated, airtight homes. A perfect compliment to an air source heat pump
