We've posted below an infographic from our typical Safety Files with practical advice on:
🌳 Passive cooling strategies to reduce overheating.
🪟 When to open (and when to keep closed) your windows.

Disclaimer: This infographic provides general guidance only and should not be considered specific technical advice for your home. Every dwelling, ventilation system and occupancy pattern is different. Always refer to the manufacturer's operating instructions for your MVHR system and seek professional advice where appropriate. During periods of extreme heat, always follow public health guidance and take additional precautions for vulnerable occupants.
