As a property investor, maximising the value and efficiency of your investments is paramount. One often overlooked yet highly impactful upgrade is the installation of mechanical ventilation systems. In this post, we explore three key systems—Positive Input Ventilation (PIV), Mechanical Extract Ventilation (MEV), and Mechanical Ventilation with Heat Recovery (MVHR)—and how they can transform your properties into energy-efficient, high-value assets.

Positive Input Ventilation (PIV)
- Moisture Control: PIV systems are excellent at reducing moisture levels, a common issue in the UK's humid climate. This helps prevent mould growth, safeguarding both the property and tenant health.
- Ease of Installation: PIV units are relatively simple to install, making them suitable for both new builds and retrofits.
- Low Maintenance: With straightforward maintenance requirements, PIV systems offer a cost-effective solution for improving air quality.
Considerations:
-No Heat Recovery: While effective at moisture control, PIV systems do not recover heat, which can impact energy efficiency.
- Limited Control: Typically operates continuously, offering less control over individual room ventilation.

Mechanical Extract Ventilation (MEV)
Advantages:
- Effective Air Removal: MEV systems efficiently remove stale air, maintaining high indoor air quality.
- Room-Specific Control: Offers precise control over ventilation in individual rooms, enhancing comfort.
- Pollution Reduction: Helps reduce indoor air pollutants, benefiting tenant health.
Considerations:
- Installation Costs: MEV systems can be costly to install, particularly in existing buildings.
- No Heat Recovery: Like PIV, MEV does not recover heat, which may lead to higher energy costs.
Mechanical Ventilation with Heat Recovery (MVHR)
Advantages:
- Heat Recovery: MVHR systems recover heat from outgoing air, significantly boosting energy efficiency and reducing heating costs.
- Humidity and Pollution Control: Maintains optimal humidity levels and reduces pollutants, ideal for allergy sufferers.
- Advanced Control: Allows for individual room ventilation control, maximising comfort.
Considerations:
- Higher Initial Costs: MVHR systems require a significant upfront investment and professional installation.
- Maintenance Needs: Regular maintenance is crucial to ensure optimal performance and energy savings.
