Essentially, the Aprilaire Energy Recovery Ventilator is an efficient, effective way to exchange stale inside air for fresh outdoor air. In winter months, the exclusive EnergyMax Transfer Core uses the heat of indoor air to warm up the incoming cold fresh air, recovering about 77% of the energy. In summer, warm fresh air passes near outgoing conditioned air, cooling it down. The beauty of the EnergyMax Transfer Core is its use of enthalpic technology. This technology enables the transfer of moisture as well as heat.
The popularity of the enthalpic-type ventilator has increased all over the country because of its superior ability to control humidity levels in both winter and summer. The result is greater indoor comfort at the lowest possible cost. Noise is also reduced, since you can enjoy fresh air without leaving windows open. Plus, a fresher, safer home is a home with greater value. While the ideal time to install Aprilaire is during construction, the Energy Recovery Ventilator can be added to any existing heating/cooling system. The climate conditions where you live will determine whether you need a Heat Recovery Ventilator or an Energy Recovery Ventilator. HRV's are usually recommended for colder climates with longer heating seasons. ERV's are used for warmer, more humid climates with long cooling seasons.
