An ERV fresh air system is a special machine that helps bring fresh air into your home while getting rid of old air. ERV stands for Energy Recovery Ventilator. It helps save energy by transferring heat and moisture between the incoming and outgoing air. This means when it's hot outside, the system cools the fresh air before it enters your home. When it's cold, it warms the air. This makes your home comfortable without using too much energy.
How does it work? The system has two fans: one for the fresh air coming in and one for the stale air going out. As the new air comes in, it passes through a heat exchanger. This part helps to transfer heat from the outgoing air to the incoming air. So, if it’s winter, the warm air leaving your house warms the cold air coming in. In summer, the cooler air coming in gets cooled down by the warmer air going out. This exchange helps save energy, which is good for your wallet. You can learn more about these systems, such as the HP-ERV & AHU, that provide efficient energy recovery.
