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.<\/p>\n
Reading a test report is a skill worth having. Confirm the rating method, the airflow at which effectiveness was measured, and whether the condition was dry or wet, because all three move the number. A Eurovent or Passive House listing tells you the figure was reproduced by a third party, not just claimed. Match the standard to your market: AHRI 1060 and ASHRAE 84 in North America, EN 308 and ISO 16494 in Europe and internationally. Then check the leakage and pressure-drop basis, since a high-effectiveness core with poor seals or a steep curve can under-deliver in the field.
