Geothermal Pipe
High-Density Polyethylene (HDPE) is the gold standard for ground source heat pump systems, thanks to its exceptional durability, flexibility, and resistance to corrosion. At Encoma, we manufacture premium geothermal pipe from virgin PE-4710 resin, meeting or exceeding ASTM D3350, delivering unmatched performance in harsh underground environments.
Key Features and Benefits:
- 50 year guarantee against rot, rust, electrolytic corrosion, and material/workmanship defects.
- Diameters from 3/4″ to 6″, with multiple wall thicknesses (DR options) to suit residential, commercial, agricultural, and directional drilling projects.
- NSF Geo certified to ASTM D3035, ASTM F714, CSA B137.1, and CSA C448.
- Superior thermal conductivity, pressure resistance, and long-term reliability — helping reduce energy costs and maintenance in ground-source systems.
- Proudly manufactured here in Manitoba, supporting local projects and Canada’s push toward sustainable heating/cooling.
Prefabricated Geo Loops
In addition to our high-performance geothermal pipe, we offer fully prefabricated Geo Loops for even greater installation efficiency.
Streamline your geothermal installations with Encoma’s prefabricated Geo Loops, engineered for vertical boreholes and directional drilling applications. These pre-assembled closed-loop systems eliminate onsite cutting and fusing hassles, reducing labor time, potential errors, and project delays.
Key Features and Benefits:
- Custom-fabricated using our premium PE-4710 geothermal pipe, cut to your exact length requirements.
- Securely fused to high-quality butt fusion U-bends for reliable, leak-proof performance.
- Fully capped and pressure-tested by our certified technicians — arrives at your site ready for immediate installation.
- Backed by the same lifetime guarantee as our geothermal pipe: no rot, rust, or corrosion concerns.
