Polyethylene Pipe and Fittings for Water-Based Ground-Source “Geothermal” Heat Pump Systems

inactive
Organization: NSF
Publication Date: 3 February 2014
Status: inactive
Page Count: 20
scope:

The physical and performance requirements in this Standard apply to plastic piping system components as well as non-plastic components of the ground loop heat exchanger including, but not limited to, pipes and fittings used in water-based ground-source heat pump systems. This Standard is intended for ground loop heat exchangers with a maximum temperature and pressure of 140 °F (60 °C) at 100 psi. Waterbased ground-source heat pump systems commonly include the use of anti-freeze, heat transfer fluids or other chemical additives. This Standard does not cover refrigerant based ground loop heat exchangers such as direct expansion (DX) systems. This Standard does not cover hydronic heating or cooling systems within buildings.

Purpose

This Standard establishes the minimum physical and performance requirements for plastic piping system components. These criteria were established for the protection of property, public health and the environment.
