The CenFuse geothermal pipes were certified by NSF International, an independent global organization that writes standards, and tests and certifies products for the water, food, health-sciences and consumer-goods markets.
The certification provides engineers, distributors and heat pump contractors assurance that not only the pipe but the entire ground-loop heat pump meet safety and quality levels, according to David Schnase, vice president of sales and marketing for the company in Hastings, Neb.
