Buying Guide
Key considerations for heat recovery ventilation components
When choosing HRV-related equipment, consider climate, space size, and existing HVAC arrangements. HRV systems focus on recovering heat from outgoing air to pre-warm incoming air, while ERVs add humidity management. For retrofit projects in cold climates, prioritize reliable heat transfer and low energy use. For moderate climates, emphasis on controllable ventilation and filtration becomes important.
How to evaluate specifications
- Airflow capacity (CFM): Match to room size and desired air changes per hour.
- Energy efficiency: Look for inverter-driven components and energy-efficient fans; check noise ratings (dB).
- Controls: Automatic sensing (differential pressure or humidity) reduces manual adjustments and improves comfort.
- Duct compatibility: Confirm diameter, length, insulation, and ease of routing through or around ceilings and walls.
- Filtration and maintenance: Availability of filters, ease of cleaning, and corrosion resistance of components.
- Weather protection: Roof vents should be weatherproof and wind/rain resistant for outdoor use.
- Integration: Assess how components can work with existing HVAC or HRV systems and potential tax credits or rebates for energy efficiency.
