How Heat Recovery Ventilation works

Have you ever wondered how to keep your home well-ventilated without losing heat during the colder months? Heat Recovery Ventilation (HRV) is an effective solution to this problem. In this article, we will explain how HRV works and its benefits.

What is Heat Recovery Ventilation?

Heat Recovery Ventilation is a ventilation system that provides fresh air to your home while also recovering heat from the air that is being expelled. The system does this by utilizing two separate airflows. One airflow brings fresh air into your home, while the other airflow expels stale air from your home. The two airflows pass through a heat exchanger, which transfers heat from the outgoing air to the incoming air, resulting in a more energy-efficient and comfortable living space.

How HRV works

HRV works by using two duct systems, one for the incoming air and another for the outgoing air. The two ducts are connected by a heat exchanger that transfers heat from the outgoing air to the incoming air. The incoming air is filtered to remove any pollutants or allergens before being circulated into your home. The outgoing air is expelled outside, along with any moisture or pollutants that may have accumulated in your home.

Benefits of HRV

1. Improved Indoor Air Quality: HRV helps to improve indoor air quality by filtering out pollutants, allergens, and other harmful particles from the incoming air. This is especially important for people with respiratory issues or allergies.

2. Energy Efficiency: HRV helps to reduce energy consumption by recovering heat from the outgoing air and using it to warm the incoming air. This means that your heating system doesn’t have to work as hard to maintain a comfortable temperature in your home, resulting in lower energy bills.

3. Comfort: HRV helps to maintain a comfortable living space by providing a constant supply of fresh air while also preventing heat loss.


In conclusion, Heat Recovery Ventilation is an excellent solution for anyone looking to improve their indoor air quality, reduce energy costs, and live more sustainably. By extracting stale air and replacing it with fresh outdoor air, HRV systems provide a constant supply of fresh air while also recovering the heat from the outgoing air. So, if you’re looking for an energy-efficient and environmentally friendly way to ventilate your home or office, Heat Recovery Ventilation is definitely worth considering.
