Récupérateur de chaleur des eaux de drainage

The absence of a nationally recognized testing standard for performance verification has been a deterrent to promote Horizontal drain water heat recovery (DWHR) systems as an energy efficient product in the marketplace. Many new and existing buildings are unable to utilize current certified vertical DWHR systems such as: buildings without basements, shallow foundations, homes on permafrost, MURBS. The development of a testing standard for horizontal units would provide additional options to meet the demand of the marketplace with approved and safe low-slope horizontal DWHR systems. Establishing a nationally accepted testing procedure for low-slope Horizontal DWHR devices will provide recognized standards that will increase the confidence of consumers and authorities having jurisdiction in this emerging technology by verifying manufacturer's claims on system performance and provide a level playing field for the various manufacturers to develop and promote their products. Once a testing standard will be established, it will be easier for individual consumer and local authorities to integrate this energy efficient technology and to benefit from the savings generated. The combination of increased consumer confidence with the backing of a utility energy efficiency program to a new technology has been proven to increase market penetration as demonstrated by previous energy efficiency programs.
