Toronto – A new video has been created by the CSA Group on the standard for the design and installation of ground source heat pump systems for use in the United States and Canada.

CSA-448 is a joint effort of the CSA Group; NGWA; the American Society of Heating, Refrigerating, and Air-Conditioning Engineers; and the International Ground Source Heat Pump Association.

Mark Metzner, chair of the technical committee on the standard, talks about the process and intention behind it. Metzner is president of the International Ground Source Heat Pump Association of Canada and president of GeoCoax for the North American region.


The CSA Group is an internationally accredited standards development, and testing and certification organization.
