- AHRI 1060: North American rating method for air-to-air heat exchangers. EN 308: European test method for heat transfer in recovery components. ISO 16494: International method for rotary exchangers. ASHRAE 84: General method for energy recovery devices.
- Eurovent certification: Independent verification of rated efficiency in Europe. ErP (EcoDesign): EU minimum efficiency thresholds for energy-related products. Passive House Component criteria: Strict effectiveness and leakage limits for PH-certified units. ENERGY STAR / local codes: Regional thresholds for ventilation equipment.
- Which standard was used for the rated effectiveness? Is the unit third-party certified (Eurovent, Passive House)? Does it meet local ErP or code minimums? Are leakage and pressure-drop measured at the same airflow?
- Are all efficiency numbers comparable? Only when tested to the same standard at the same airflow and conditions; always check the basis. Does certification matter for small units? Yes - it protects you from overstated claims and supports code compliance and rebates.
When you specify or buy a heat recovery unit, third-party standards tell you the numbers are comparable and real. Knowing the key marks helps avoid inflated claims.
