MVHR System
(Mechanical Ventilation with Heat Recovery)
An MVHR system is a whole-house ventilation system that continuously extracts stale air and supplies fresh, filtered air — while recovering heat that would otherwise be lost.
It is commonly installed in new builds, low-energy homes, and airtight properties.
A professionally installed
Mechanical Ventilation with Heat Recovery (MVHR) system delivers continuous fresh air while recovering up to 96% of the heat that would otherwise be lost.
How it works:
1. Stale Air Is Extracted
Warm, moisture-laden air is continuously removed from:
- Bathrooms
- Kitchens
- Utility rooms
This removes humidity, odours, and airborne pollutants.
2. Fresh Air Is Drawn In
At the same time, the system pulls fresh air from outside your home.
Before entering the property, the air passes through filters to remove:
- Dust
- Pollen
- Insects
- Outdoor pollutants
3. Heat Is Recovered (Without Mixing Air)
Inside the MVHR unit is a heat exchanger.
The outgoing warm air passes through one side of the heat exchanger.
The incoming fresh air passes through the other side.
The heat transfers across the exchanger — but the air streams never mix.
This means:
- Fresh air is warmed using recovered heat
- You don’t lose valuable heating energy
- Indoor air stays clean and filtered
Modern systems can recover up to 70–96% of heat.
4. Fresh, Warmed Air Is Supplied to Living Spaces
The pre-warmed, filtered air is then distributed to:
- Living rooms
- Bedrooms
- Home offices
This creates balanced airflow throughout the property.
It works 24/7 to keep your home:
✔ Fresh
✔ Comfortable
✔ Energy-efficient
✔ Condensation-free
All without opening windows or losing valuable heat.
The Perfect Partnership: Heat Pumps & MVHR
Lower Bills. Better Comfort. Smarter Heating.
When installed together, they create a highly efficient, low-carbon heating and ventilation solution.
Together, they create a home that is:
✔ Warmer in winter
✔ Cooler in summer
✔ Healthier to live in
✔ Cheaper to run
Here are the key benefits when installed together:
Lower Energy Bills
A heat pump, such as an air source heat pump, works most efficiently at lower, steady temperatures.
An MVHR system recovers heat from outgoing air and reuses it — meaning your heat pump doesn’t need to work as hard.
Result: Reduced electricity use and lower running costs.
Consistent, Even Comfort
Heat pumps deliver steady warmth rather than intense bursts of heat.
MVHR eliminates cold draughts and distributes pre-warmed fresh air throughout the property.
No temperature swings. No cold spots. No wasted heat.
Designed for Modern Airtight Homes
Today’s homes are built to be highly insulated and airtight.
- The heat pump provides efficient, low-carbon heating
- The MVHR supplies constant fresh air without losing heat
Without MVHR, airtight homes can suffer from condensation, stale air, and mould risk.
Together, they create a perfectly balanced indoor environment.
Healthier Indoor Air Quality
While the heat pump manages temperature, MVHR:
- Removes moisture
- Filters dust and pollen
- Reduces allergens
- Prevents condensation
Your home feels fresher, cleaner, and more comfortable all year round.
Future-Proof & Low Carbon
Combining heat pump technology with MVHR:
- Reduces carbon emissions
- Supports higher EPC ratings
- Meets modern building standards
- Increases property appeal and value
It’s the complete heating and ventilation solution for forward-thinking homeowners.

Is MVHR suitable for all homes?
MVHR works best in:
-New build properties
-Airtight, well-insulated homes
-Deep renovation projects
-In older, draughty homes, airtightness improvements are usually required for MVHR to be effective.
Does MVHR replace heating?
No.
MVHR is a ventilation system, not a heating system. It reduces heat loss but does not replace radiators, underfloor heating, or heat pumps.
Will MVHR reduce condensation and mould?
Yes.
By continuously removing moisture from bathrooms and kitchens, MVHR helps control humidity levels, reducing condensation and mould risk.
Is an MVHR system noisy?
No.
When professionally designed and installed, MVHR systems operate quietly and run continuously at low speed. Boost modes are available for cooking or showering.
What maintenance does MVHR require?
Maintenance is simple:
Filters should be replaced every 6–12 months
The unit should be serviced periodically
Ductwork may require occasional inspection
Regular maintenance ensures efficiency and long system life.
Can MVHR be retrofitted?
Yes, but it is easier and more cost-effective during new builds or major renovations, as ducting must be installed throughout the property.
Does MVHR improve EPC ratings?
Yes.
Because it reduces heat loss and improves energy efficiency, MVHR can contribute positively toward a better EPC rating.
