Heat Recovery Ventilation

MVHR (Mechanical Ventilation with Heat Recovery) units that supply filtered fresh air while recovering up to 90% of the energy from extracted stale air.

MVHR is a non-negotiable for tight-built modern homes — Passivhaus, certified high-performance builds, and any home with a high-quality envelope.

We supply Zehnder ComfoAir, Stiebel Eltron LWZ, Mitsubishi Lossnay and Brink Renovent. Sizing is critical — undersized units short-cycle, oversized units waste energy.

Key benefits

  • Up to 90% heat recovery
  • F7 + G4 dual filtration
  • Whisper-quiet — under 25dB
  • Wi-Fi controls
  • Summer bypass mode
  • BAL bushfire-rated options
FAQs

Common questions

Do I need MVHR?

Essential for tight-built modern homes (Passivhaus, certified high-performance), homes with high indoor pollutant levels, asthma/allergy sufferers, and any home in bushfire-prone areas. Older draughty homes can usually skip it.

Which brand to choose?

Zehnder ComfoAir (premium, quietest), Stiebel Eltron LWZ (German), Mitsubishi Lossnay (good value), Brink Renovent (Dutch). We size each unit to your home's air volume — undersized cycles too fast, oversized wastes energy.

How loud are MVHR units?

Whisper-quiet — under 25dB at the diffuser on normal mode. The unit itself is mounted in a service area (laundry, garage, plant room) where you don't notice it. Boost mode (during cooking) is louder but still acceptable.
