Drain-water heat recovery
Drain-water heat recovery
Changes are underway to the database that supports this list. As of March 14, 2025, the list has been frozen. Until the updated version is released, an interim version is available at the link below (.xlsx format).
Drain-water heat recovery units found in this database have been tested by a third party accredited by the Standards Council of Canada under CSA B55.1 – Test Method for Measuring Efficiency and Pressure Loss of Drain Water Heat Recovery Units. The Standard specifies requirements for measuring the heat recovery efficiency and pressure loss for drain-water heat recovery units.
The efficiency of a drain-water heat recovery unit is measured by a value called the Heat Recovery Efficiency, which is expressed as a ratio between the actual heat transfer and the theoretical maximum possible heat transfer. After selecting the size required, choose high heat recovery efficiency models, based on the unit’s orientation, as these are the most efficient.
