What is MVHR and Why Does Your Home Need It?

Understanding Mechanical Ventilation with Heat Recovery from Clear Skies Energy

As we move toward more energy-efficient, airtight homes, indoor air quality becomes increasingly important. Mechanical Ventilation with Heat Recovery (MVHR) is a smart, sustainable solution that helps homes stay fresh, comfortable and energy-efficient — all year round.

What is MVHR?

MVHR 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. But it doesn’t stop there — the real benefit lies in its ability to recover heat from the outgoing air and use it to warm the incoming air.

This means your home stays ventilated without the need to open windows, keeping heat in during the winter and improving overall energy efficiency.

How Does It Work?

  1. Warm, stale air is extracted from ‘wet’ rooms like kitchens, bathrooms and utility rooms.
  2. This air passes through a heat exchanger, transferring its warmth to the fresh air drawn in from outside.
  3. The filtered, pre-warmed air is then distributed to living areas and bedrooms.
  4. Stale air is expelled, but the heat is retained — saving energy and money.

Benefits of MVHR

  • Energy Efficiency: Reduce heat loss and lower your heating bills.
  • Healthier Air: Constant fresh air supply, filtered to remove dust, pollen, and pollutants.
  • Moisture Control: Prevents condensation, damp, and mould growth.
  • Comfort: Balanced ventilation without cold draughts or stuffy rooms.
  • Quiet Operation: Discreet, low-noise systems designed for modern homes.

MVHR is ideal for new builds and well-insulated renovation projects. The system works best in airtight homes where natural ventilation is limited.
