Geothermal Ground Loops

Horizontal Collector / Header Pipes Manufactured from Virgin Grade Black PE100 High Performance Polyethylene (EN12201) Go Geothermal offer a “true” geothermal collector pipe: • 40mm Pipe marked with a green stripe for clear identification of ground source collector pipe • Pipe manufactured specifically for heat collection • Available in coil sizes from 50m to 500 metres Header pipe available in sizes up to & including 315mm OD Horizontal Collector / Header Pipes PE100-RC Used extensively in mainland Europe PE100-RC Collector pipe offers superior impact crack resistance to PE100. This product in most soil conditions negates the use of sand bedding, saving significant material, plant and labour cost. Conductivity of the sand versus site soil conditions must always be considered in the analysis before opting for non sand bed. A fundamental and critical component of any efficient performing Ground Source Heat Pump System is the collector pipes where pipe protection and longevity are paramount. It's widely accepted in terms of good pipe laying practice that sand should be employed both below and above the pipe to protect from sharps as even PE100 Pipe Material is vulnerable to rapid creep if point load damage occurs. Whilst sand does offer the potential for improved thermal conductivity in poor soils it has become the default position on most installs to lay a sand bedding as traditionally pipe needed protection from the variants of “as dug material” thereby always adding that cost into the job in material and significant labour time. Go Geothermal can offer you a solution, PE100-RC. Offering low notch sensitivity and superior resistance to point loading and slow crack growth (SCG), the RC material avoids the potential for pipe tears even when point loads caused by rocks occur. By utilising this pipe in the correct soil conditions NO sand back fill is required! This reduces capital outlay and significant labour time and plant on site. We are pleased to offer this product as yet another step in the improvement of the technical quality of Ground Source materials. Horizontal Collector / Header Pipes PE-Xa Advantages PE-Xa collector pipe: 1. Resistant to puncture loads, notches and grooves – allowing the pipe to be backfilled with excavated material (PE 100 requires a sand bed), therefore reduction of installation time and costs 2. Better thermal efficiency of excavated material compared to a dry sand bed 3. Extremely tough and able to handle temperatures up to 95oC 4. Tight bending radii, therefore easier installation as less space is required 5. High operational reliability of PE-Xa pipe 6. Minimal pressure losses due to smooth pipe inner surface
