Centennial Geothermal Exchange Pipe

The Smart Choice for Closed-Loop Geothermal Heat Pump Systems.

Geothermal heat pump systems are rapidly becoming the heating and cooling method of choice for residential and commercial buildings across the country. The fact is, geothermal systems create significant cost savings over even the most efficient conventional forced air systems.

Engineers and architects often specify Centennial geothermal products, because they are expressly engineered to withstand the working pressures and temperatures of a geothermal heat pump system. Also, contractors prefer the ease and economy of installing Centennial's exchange pipe.

Centennial Plastics belongs to The International Ground Source Heat Pump Association (IGSHPA), a non-profit organization established to advance ground source heat pump (GSHP) technology on local, state, national and international levels. We are also a member of the Geo Exchange Organization. This organization works to increase the use of geoexchange technology throughout the world with the goal of dramatically reducing greenhouse gas emissions, as well as reducing energy costs and our dependence on fossil fuels.

Centennial Plastics CenFuse geothermal pipe is the first pipe to be certified by the new standard NSF/ANSI 358-1.  Learn more about this standard at NSF.org and about our certification on the National Driller Blog

Earth Loops

Earth Loops

Primary Use:

Centennial earthLoops logo allow for efficient vertical and directional boring.

The patented one-piece Centennial Bullet™ U-Bend fitting guides the EarthLoops™ down the bore hole with ease.

Contractors can now eliminate the time-consuming chore of fusing pipe to fittings. Coils of geothermal CenFuse pipe are securely fused to the Centennial Bullet™ U-Bend fittings at our manufacturing facility. The result is our exclusive Centennial EarthLoop™, which is ready to install the moment it arrives at the job site.

Centennial Bullet™ U-Bend Fittings accomodate CenFuse pipe in 3/4", 1" and 1 1/4" diameters, and they are the narrowest U-bend fittings on the market today -- allowing a narrower bore hole which requires less grout and less annular space for more efficient drilling.
