Does Positive Input Ventilation Make Your House Cold?


Positive Input Ventilation (PIV) systems have gained popularity in recent years for their ability to improve indoor air quality and reduce issues like condensation and dampness. However, a common concern among homeowners is whether PIV can make their houses feel colder. In this blog post, we will explore the relationship between PIV systems and temperature and dispel the common misconception that they make your house cold.

Understanding Positive Input Ventilation

Positive Input Ventilation is a ventilation strategy that involves the introduction of fresh, filtered air into a home from outside, typically using a fan and ducting. The main purpose of PIV is to control humidity levels and eliminate condensation problems. PIV systems are commonly installed in areas where excessive moisture and dampness are issues, such as bathrooms, kitchens, and basements.

The Science Behind PIV

To understand whether PIV makes your house colder, it’s essential to grasp the scientific principles at play. PIV systems primarily operate by diluting and replacing stale, humid air with fresh, dry air from outside. However, this fresh air is typically brought in at a controlled rate, which means that the temperature inside your home remains relatively stable.

The Temperature Myth

One common misconception is that PIV systems introduce cold air into your living space, which can lead to a decrease in temperature. In reality, PIV systems do not cause a significant drop in indoor temperature. The fresh air brought in through PIV is typically at a similar temperature to the indoor air, especially in well-insulated homes. The primary function of PIV is to maintain a healthy humidity level, not to cool the house.

Maintaining Comfort

While PIV doesn’t make your house colder, it does contribute to creating a more comfortable living environment. By controlling humidity and reducing condensation, PIV can help prevent cold spots and dampness, making your home feel warmer and cozier. It ensures that the air inside your home is not too moist, which can make it feel colder and uncomfortable, especially during the winter months.

Energy Efficiency

Another important point to consider is the impact on energy efficiency. PIV systems are designed to be energy-efficient, so they don’t significantly increase your heating costs. In fact, by preventing condensation and reducing the need for dehumidifiers or additional heating, they can help you save on energy bills in the long run.

Balancing PIV with Heating

If you’re concerned about the potential for a slightly cooler feel due to PIV, you can easily address this by adjusting your heating system. PIV and heating should work in harmony to maintain a comfortable temperature. If needed, you can set your heating system to a slightly higher temperature to offset any cooling effects from PIV, ensuring that your home remains warm and cozy.

Conclusion regarding the question – Does positive input ventilation make your house cold?

In conclusion, Positive Input Ventilation (PIV) systems do not make your house cold. They are designed to maintain a healthy indoor environment by controlling humidity and preventing issues like condensation and dampness. While PIV may introduce fresh air from outside, it does so at a controlled rate, ensuring that your indoor temperature remains stable. To achieve the ideal comfort level in your home, it’s essential to balance PIV with your heating system. PIV contributes to a healthier, more energy-efficient living environment without making your house feel uncomfortably cold.

We hope this blog post has answered the question for you – Does positive input ventilation make your house cold?
