Probes & Horizontal Ground Loops

Probes

Our European sourced Probes aka Ground Loops are made from High Density Polyethylene (PE100) and is 100% Virgin Resin. The pipe is manufactured specifically for heat collection ensuring peace of mind and a superior thermal conductivity. The U-Bend on the Probes is factory butt welded to the pipe (and individually factory tested - and externally monitored), again ensuring peace of mind. The probes come with a certificate with a unique identifer for borefield logging purposes.

The probe tip includes vertical ribbing and is arrowed for a safer installation. This ribbing provides more secure mechanical protection for the welded probe tip.

We also stock PE-Xa probes, for more details please click here.

PE100 Coils

Continuing our ethos of premium products our UK sourced black pipe coils are also made from High Density Polyethylene (PE100) and is 100% Virgin Resin. The pipe is manufactured specifically for heat collection ensuring peace of mind and a superior thermal conductivity.

PE100 RC Pipe (Resistance to Crack)

A fundamental and critical component of any efficient performing Ground Source Heat Pump System are 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 Limited 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.

Go Geothermal are pleased to offer this product as yet another step in the improvement of the technical quality of Ground Source materials.

PE-Xa Coils

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. Tight bending radii, therefore easier installation as less space is required
4. High operational reliability of PE-Xa pipe
5. Minimal pressure losses due to smooth pipe inner surface
