Understanding Dryer Vent Heat Exchangers

When I first heard about dryer vent heat exchangers, I was curious about how they worked. Essentially, these devices capture the warm air that would typically escape through the dryer vent and recycle it to help heat my home. By doing this, they not only improve energy efficiency but also reduce my utility bills.

Why Should I Consider One?
