MVHR (Mechanical Ventilation with Heat Recovery)
✔
Lower energy bills:
Recovers ~70–90% of heat from exhaust air, reducing heating demand—useful in London’s mild but long heating season.
✔
Better air quality:
Constant fresh, filtered air helps remove pollutants, allergens, and traffic-related NO₂ common in London.
✔
Moisture & mould control:
Balanced ventilation reduces condensation—ideal for larger, well-insulated homes.
✔
Comfort & consistency:
Even temperatures, fewer draughts than window ventilation.
✔
Quiet & secure:
Less need to open windows (noise, security, pollution).
✔
Future-proofing:
Works well with airtight builds, heat pumps, and helps meet Part F/L compliance.
Real-world performance example
A recent client installation in a
mid-terrace house with an L-shaped loft conversion and side return extension
combined:
- MVHR system
- Air source heat pump
- Upgraded insulation to the existing house floor and external walls
The property now operates without any gas connection, and the
total annual cost for electricity, heating, and hot water is approximately £1,300 per year
— around £108 per month. The home has also been future-proofed for a 6kW solar PV installation; if installed, this could generate around £1,500 per year, meaning the home may not only eliminate energy bills but potentially produce a net annual saving.
This shows how MVHR, when integrated with good insulation and a heat pump, can deliver
low running costs, excellent comfort, and a fully electric, future-ready home.
