With A Lennox HRV Or ERV Ventilation System, You Can Breathe Easy When Your Home's Shut Tight

To keep energy bills down, many homes are shut tight for the winter. There is an unfortunate side effect to shutting up your home, however. The air inside can become polluted and stale, with not enough moisture. This can adversely affect your health. An effective ventilation system will address these issues.

There are two main types of mechanical ventilation, exhaust-only systems and balanced systems. To keep the pressure balanced in your home, you want the second option, which supplies fresh outdoor air as it exhausts stale indoor air. Many ventilation systems come with heat or energy recovery features to reduce the cost of operating the system. Heat recovery ventilation (HRV) transfers heat while energy recovery ventilation (ERV) transfers both heat and moisture.

The incoming air in HRV and ERV systems is tempered in a heat recovery core. The airstreams pass one another but do not mix, which allows the heat from the outgoing air to transfer to the incoming air in the winter and vice versa in the summer.

Choosing an ERV over an HRV makes sense if you're having trouble controlling humidity in your home, with the air too dry in winter and too moist in summer. In an ERV, both heat and humidity are transferred into the incoming air in the heat recovery core, while heat and moisture are transferred to the outgoing air in the summer.

If your home is energy efficient, with tightly sealed walls, windows and doors, the quality of your indoor air could be improved drastically with the addition of a heat or energy recovery ventilation system. Save energy and breathe easier by exploring the possibility of an installation today.
