Polytubes extrudes its Geothermal pipe from 100% Virgin High Density Polyethylene (H.D.P.E) resin. Our H.D.P.E material is chosen for it excellent combination of toughness, durability, and Environmental stress crack resistance. Our Geothermal resins are listed by the Canadian Standard Association (CSA) and the Plastic Pipe Institute (PPI) as a PE 3608 resin with a hydrostatic design basis (HDB) of 1600psi for water at 23 degrees C and meets the cell classification of PE345464 as defined by ASTM D3350.

Polytubes was the first in the geothermal piping industry to manufacture a Green Geothermal pipe. The first production run of Green Geothermal pipe was done in our Ontairo manufacturing facilty in 2005. Polytubes Green Geothermal pipe has quickly become the standard to which all engineers, well drillers, rely on to guaruntee a quality installation. Polytubes offers Geothermal piping in black and green, sizes from 1/2" to 24" applications. Polytubes geothermal pipes comes in packaging configurations of sticks, coils and large reels.

Geothermal Info: 

A Geothermal Heating/Cooling System, also known as a ground source system, uses the earth as either a heat source, when operating in heating mode, or a heat sink, when operating in cooling mode. All geothermal systems are characterised by an external (ground) loop and an internal (building) loop, each containing refrigerant. These loops can deliver heating and cooling directly to ground or building or, via heat exchangers, through secondary loops containing water (or an antifreeze mixture with water and propylene glycol, denatured alcohol, or methanol). Secondary loops are popular for ground use because they are not pressurized, so High Density Polyetheylene Piping can be used, and because they reduce the amount of expensive refrigerant required.

Geothermal Systems use one of the following types of external loops:

• Open Loop
• Closed Vertical Loop
• Closed Horizontal Loop
