Before we dive into the specifics, let’s start with a brief definition of balanced ventilation.

Definition of Balanced Ventilation

Balanced ventilation is a system that is designed to ensure a constant supply of fresh air while simultaneously extracting stale air from your home. Unlike natural ventilation, which relies on air leakage through cracks and openings, or mechanical ventilation systems that only introduce or extract air, balanced ventilation systems strive to maintain a balance between the two.

This type of ventilation system typically consists of an intake and an exhaust. The intake brings fresh air from outside into your home, while the exhaust removes stale air from the inside. The key feature of balanced ventilation is that it incorporates a heat recovery or energy recovery mechanism, which allows for the exchange of heat or energy between the incoming and outgoing air streams. This helps to regulate the temperature and humidity levels in your home while maintaining a continuous flow of fresh air.

One of the main purposes of balanced ventilation is to improve indoor air quality. Indoor air can get contaminated with pollutants such as dust, pollen, pet dander, mold spores, and volatile organic compounds (VOCs) from household products. By introducing fresh air and removing stale air, balanced ventilation systems help to reduce the concentration of these pollutants, promoting a healthier living environment.

In addition to improving air quality, balanced ventilation systems also help to control moisture levels in your home. Excess moisture can lead to mold growth, which can cause health issues and damage to your home. With a balanced ventilation system in place, the exchange of air allows for the removal of moisture-laden air and the introduction of drier fresh air, preventing the buildup of humidity and mitigating the risk of mold growth.

Now that we have a clear understanding of what balanced ventilation is, let’s explore how these systems work in more detail.

How Balanced Ventilation Systems Work

Balanced ventilation systems work by creating a controlled and balanced airflow throughout your home. They consist of two main components: the intake and the exhaust.

The intake component is responsible for bringing fresh air from outside into your home. This is typically achieved through vents or ducts that are strategically placed in areas such as the living room, bedrooms, or hallways. The fresh air is filtered to remove any pollutants and then distributed evenly throughout the home.

On the other side, the exhaust component removes stale air from inside your home. This can be achieved using vents or ducts that are strategically placed in areas where stale air tends to accumulate, such as bathrooms, kitchens, or laundry rooms. The stale air is then expelled outside, creating a constant flow of fresh air.

What sets balanced ventilation systems apart is the incorporation of a heat recovery or energy recovery mechanism. This mechanism allows for the transfer of heat or energy between the incoming and outgoing air streams. In cold climates, a heat recovery ventilator (HRV) is used to capture the heat from the outgoing air and transfer it to the incoming fresh air. Similarly, in hot climates, an energy recovery ventilator (ERV) is used to transfer the coolness from the outgoing air to the incoming fresh air.

By recovering heat or energy from the outgoing air, balanced ventilation systems are able to regulate the temperature and humidity levels in your home. This not only provides a comfortable living environment, but it also helps to reduce energy consumption and lower utility bills.

It is important to note that balanced ventilation systems are designed to operate continuously or on a scheduled basis. This ensures a consistent supply of fresh air and efficient removal of stale air. Some systems may also come equipped with sensors that monitor indoor air quality and adjust the ventilation rates accordingly.

Now that we understand how balanced ventilation systems work, let’s explore the numerous benefits they provide for homeowners.
