What’s the Difference Between Energy Recovery Ventilation and Heat Recovery Ventilation?

Understanding the difference between Energy Recovery Ventilation (ERV) and Heat Recovery Ventilation (HRV) is crucial for optimizing your home’s indoor air quality and energy efficiency. While both systems improve ventilation and reduce energy costs, they operate differently and offer distinct benefits.
How Energy Recovery Ventilation Works
Energy Recovery Ventilation systems transfer both heat and moisture between incoming and outgoing air streams. During the summer, ERVs capture the coolness and moisture from the exhaust air and transfer it to the incoming warm air, reducing the workload on your cooling system. In winter, they transfer the warmth and humidity from the outgoing air to the incoming cold, dry air, helping to maintain comfortable indoor humidity levels and reduce heating demands. This dual-functionality makes ERVs particularly beneficial in regions with extreme temperatures and humidity levels.
How Heat Recovery Ventilation Works
Heat Recovery Ventilation systems, on the other hand, focus solely on heat transfer. HRVs capture heat from the stale indoor air and transfer it to the fresh, incoming air without mixing the two air streams. This process helps retain the warmth inside your home during colder months while providing fresh air circulation. In warmer months, the system works in reverse, expelling warm indoor air and bringing in cooler outdoor air. HRVs are ideal for climates with moderate humidity levels and significant seasonal temperature variations.
Which System is Right for You?
Choosing between an ERV and HRV depends on your climate, home insulation, and specific needs. ERVs are generally better suited for humid climates or homes with high indoor humidity levels, as they help balance moisture. Conversely, HRVs are often preferred in drier, colder climates where controlling indoor humidity is less of a concern. Consulting with a professional can help you determine which system best meets your home’s requirements.
