Frequently Asked Questions
Common questions about MVHR heat recovery systems in Sussex
What is MVHR and how does it work?
MVHR (Mechanical Ventilation with Heat Recovery) systems extract stale, humid air from kitchens, bathrooms and utilities areas, recovering the heat before expelling it. The system then draws in fresh air from outside, passes it through the heat exchanger to warm it with the recovered heat, and distributes this fresh, filtered air throughout your property. Modern MVHR systems from manufacturers like Zehnder can recover up to 90% of heat that would otherwise be lost, significantly improving energy efficiency while ensuring a constant supply of fresh, filtered air.
Is MVHR suitable for existing homes in Sussex?
Yes, while MVHR is often installed in new builds, we specialize in retrofit installations across Sussex homes. Our team carefully assesses your property to determine the most effective and least disruptive installation approach. We consider factors like property age, construction type, and existing ventilation to design a system that works efficiently. Nuaire offers specific retrofit solutions that are particularly beneficial for homes that have been insulated to modern standards, as these can suffer from poor ventilation and condensation issues that MVHR effectively resolves.
How much does MVHR installation cost in Sussex?
MVHR installation costs in Sussex typically range from £4,000-£8,000 for an average home, depending on property size, system complexity, and whether it's a new build or retrofit. This includes the unit, ducting, vents, controls, and professional installation. While this represents an initial investment, many homeowners see returns through reduced heating bills (typically 15-30% savings), improved air quality, and elimination of condensation-related maintenance costs. Quality systems from Vent-Axia and other manufacturers provide excellent long-term value. We provide detailed, transparent quotes following a thorough on-site assessment of your specific requirements.
Can MVHR be used with air conditioning?
Absolutely. MVHR and air conditioning systems complement each other perfectly. MVHR handles ventilation, ensuring fresh air circulation and recovery of heat, while air conditioning manages temperature control. When integrated professionally, these systems work together to create optimal indoor comfort with maximum energy efficiency. Zehnder's advanced MVHR systems are designed to work seamlessly with modern climate control solutions. We specialize in designing integrated climate solutions where MVHR provides continuous fresh air while reducing the workload on your heating and cooling systems, resulting in better performance, lower running costs, and improved air quality.
How long does MVHR installation take?
A typical MVHR installation in Sussex takes 2-5 days depending on property size and complexity. New builds are generally quicker as the system is installed during construction. Retrofit installations in existing properties may take longer as we work carefully to minimize disruption and ensure discreet integration with your home. Systems from Nuaire and Vent-Axia are designed for efficient installation. Our experienced team works efficiently, keeping you informed throughout the process, and ensuring all work areas are left clean and tidy each day. We provide a specific timeframe for your project after the initial site assessment.

How MVHR Systems Work: Energy-Efficient Home Ventilation
Understanding the mechanics behind energy-efficient heat recovery ventilation technology for improved indoor air quality
The MVHR Process Explained
- 1
Extract Stale Air
The system continuously extracts warm, moist air from kitchens, bathrooms and utility areas, improving indoor air quality. This extraction process helps eliminate excess humidity, cooking odors, and airborne pollutants that can accumulate in enclosed spaces.
- 2
Recover Heat Energy
Before expelling stale air, it passes through a high-efficiency heat exchanger to capture up to 90% of its thermal energy. This process retains valuable heat that would otherwise be lost, significantly reducing energy consumption and heating costs during colder months.
- 3
Filter Fresh Air
Fresh air is drawn from outside and passes through high-grade filters to remove dust, pollen, and airborne pollutants. These specialized filters trap particles as small as 0.3 microns, providing benefits for allergy sufferers.
- 4
Heat Transfer Process
The filtered fresh air is warmed by the recovered heat in the heat exchanger, maximizing energy efficiency. This occurs without airstreams mixing, ensuring only thermal energy is shared while maintaining optimal indoor air quality.
- 5
Distribute Fresh Air
The warmed, filtered fresh air is distributed throughout living spaces via discreet vents for constant healthy ventilation. This ensures every room receives adequate fresh air while preventing condensation and maintaining consistent temperatures.
Key MVHR Components & Manufacturers
MVHR Units
The central unit containing fans, filters and the heat exchanger, usually installed in a loft, utility room or cupboard. Leading manufacturers include Nuaire, Vent-Axia, and Zehnder.
Ducting Networks
Insulated ducts connecting the central unit to extract points and supply vents throughout the property. Nuaire's ducting solutions offer optimal airflow with minimal heat loss.
Extract Valves
Located in "wet" rooms like kitchens and bathrooms to remove humid, stale air. Vent-Axia provides reliable extraction valves with adjustable flow rates.
Supply Valves
Placed in living areas and bedrooms to deliver fresh, filtered, warmed air. Zehnder's supply valves are designed for optimal air distribution.
