Considering mechanical heat recovery ventilation in older homes? Installing a Mechanical Ventilation with Heat Recovery (MVHR) system in an older home can bring many benefits, but it also comes with some challenges. MVHR systems help improve indoor air quality while recovering heat, making your home more energy efficient.
However, older homes might need additional work to accommodate the system, like improving insulation or finding space for the ductwork. The good news is that with the right approach, it’s possible to enjoy the advantages of MVHR even in older buildings.
In this blog, we will help you explore the benefits and installation considerations of MHRV for older homes.
Let’s explore how suitable MVHR systems are for older homes and what you should consider before installation!
What Are the Key Considerations for Older Homes Related to MVHR?
Older homes can benefit greatly from MVHR systems, but it’s important to address these challenges before installation.
1. Insulation and airtightness
Older homes often have poor insulation and are less airtight compared to newer buildings. This can affect the efficiency of a Mechanical Ventilation with Heat Recovery (MVHR) system, which works best in well-insulated, airtight spaces.
Before installing an MVHR, you might need to upgrade your home’s insulation to ensure the system operates efficiently and delivers the expected energy savings.
2. Space for ductwork and equipment
MVHR systems require space for ductwork, vents, and a central unit, which can be challenging to accommodate in older homes with limited or unconventional layouts.
It’s essential to plan where the system will fit without causing significant disruption to the structure or appearance of the house. Sometimes, minor renovations or creative solutions may be needed to integrate the system smoothly.
3. Structural assessment
Older homes might have different layouts or structural constraints that can affect the installation.
A professional installer should assess the house to determine the best way to integrate the MVHR system without affecting the building’s integrity. This step ensures that the installation is both safe and effective.
4. Professional installation
Installing an MVHR system in an older home requires expertise. It’s not a DIY project, as the system needs to be carefully balanced to ensure proper ventilation and heat recovery.
A professional will evaluate the house’s requirements, design the system layout, and ensure proper installation for optimal performance.
By carefully considering these factors, you can successfully install an MVHR system in an older home.
What Are the Benefits of Retrofitting MVHR in Older Homes?
1. Improved indoor air quality
One of the biggest advantages of retrofitting an MVHR system in older homes is the significant improvement in air quality. Older homes often suffer from poor ventilation, which can lead to issues like excess humidity, stale air, and even mould growth.
MVHR systems continuously bring in fresh air from outside while filtering out pollutants and allergens, ensuring a healthier living environment for you and your family.
2. Energy efficiency and cost savings
Retrofitting an MVHR system not only enhances air quality but also makes your home more energy-efficient. By recovering heat from the outgoing air and using it to warm incoming fresh air, MVHR systems help reduce the demand on your heating system.
This means lower energy bills over time, making the system a smart investment for long-term savings, even in older, less energy-efficient homes.
3. Reduced Condensation and Moisture Control
Older homes are more prone to issues like condensation and moisture buildup due to outdated or ineffective ventilation systems. MVHR systems help regulate moisture levels by consistently expelling humid air and replacing it with fresh, dry air.
This can prevent common problems like dampness and condensation, which can damage your home’s structure and lead to costly repairs.
Installing an MVHR system offers clear benefits for older homes, but it’s important to ensure your home is prepared for the installation.
Conclusion
While installing a Mechanical Heat Recovery Ventilation (MVHR) system in an older home can present challenges, such as ensuring proper insulation and accommodating ductwork, the benefits are worth the effort.
MVHR systems improve indoor air quality and energy efficiency, making your home more comfortable and cost-effective in the long run. With the right professional guidance, older homes can successfully integrate these systems for modern ventilation.
