Improve Your Home's Air Quality and Energy Efficiency

In the pursuit of creating a comfortable and energy-efficient home, indoor air quality often gets overlooked. Yet, it’s a crucial factor that significantly affects both our health and the efficiency of our living spaces. One of the most effective ways to enhance indoor air quality while also improving energy efficiency is through Positive Input Ventilation (PIV). At Save Energy Insulation, we understand the importance of maintaining a healthy and energy-efficient home, and we’re here to guide you through the benefits of PIV and how it can transform your living environment.

    What is Positive Input Ventilation (PIV)?

    Positive Input Ventilation is a ventilation system designed to improve indoor air quality by reducing humidity and pollutants. It works by gently introducing fresh, filtered air into your home, typically through a unit installed in the loft. This fresh air disperses throughout the house, pushing out stale, moist air and replacing it with clean, dry air.

    PIV systems are particularly beneficial in homes that suffer from condensation, dampness, and mould issues. By ensuring a continuous supply of fresh air, PIV helps to regulate humidity levels, making your home healthier and more comfortable.

    Humidity Pollutants Filtered Air


    This incoming air is filtered to remove pollutants, dust, and allergens, ensuring that only clean air enters your home.

    Air Distribution

    The filtered air is then gently pushed into your living space through a central diffuser, usually located in the ceiling of the hallway or landing.

    Positive Pressure

    As the clean air is introduced, it creates a slight positive pressure within the house. This positive pressure forces out the stale, humid air through natural leakage points such as window vents and gaps in the building fabric.

    Continuous Cycle

    This process is continuous, ensuring a constant supply of fresh air while expelling the old, polluted air.

    Improved Indoor Air Quality

    One of the most immediate benefits of PIV is the significant improvement in indoor air quality. By introducing a constant flow of fresh air and expelling pollutants, PIV systems help to reduce the concentration of harmful substances such as carbon dioxide, volatile organic compounds (VOCs), and indoor allergens. This is particularly beneficial for individuals with respiratory conditions or allergies.

    Reduction in Condensation and Mould

    Condensation and mould are common problems in many homes, often resulting from poor ventilation. PIV systems help to regulate humidity levels, reducing the likelihood of condensation forming on walls and windows. This, in turn, helps to prevent the growth of mould, which can cause structural damage and pose serious health risks.

    Energy Efficiency

    While it might seem counterintuitive that a ventilation system could improve energy efficiency, PIV can actually help to reduce heating costs. By maintaining a consistent airflow and balanced humidity levels, PIV systems can make your home feel warmer and more comfortable without the need to crank up the heating. Additionally, many modern PIV units come with heat recovery features that further enhance energy savings.

    Easy Installation

    Installing a PIV system is a straightforward process that can be completed with minimal disruption to your home. The unit is typically installed in the loft, and the diffuser can be placed in a central location such as the landing or hallway. Professional installation ensures that the system operates efficiently and effectively.

    Positive Input Ventilation vs. Traditional Ventilation Systems

    It’s important to understand how PIV compares to other traditional ventilation systems, such as extract fans and passive vents. Here are a few key differences:

    • Extract Fans: Extract fans work by removing air from specific areas, such as kitchens and bathrooms, and expelling it outside. While effective at removing moisture and odours, they can create negative pressure, drawing in unfiltered air from outside or other parts of the house. PIV, on the other hand, creates positive pressure, ensuring that all incoming air is filtered and fresh.
    • Passive Vents: Passive vents allow for natural airflow based on pressure differences inside and outside the home. However, they are less effective at controlling air quality and humidity levels compared to PIV systems, which actively manage these factors.

    Mechanical Ventilation with Heat Recovery (MVHR): MVHR systems provide a balanced ventilation approach with heat recovery, similar to advanced PIV units. However, MVHR systems are generally more complex and expensive to install. PIV offers a simpler and more cost-effective solution with comparable benefits.
