Go Geothermal Ltd

At the heart of our offering Go Geothermal has both Ground and Air Source units from 3kw to 1MW demand. Having played a major part in the UK Heat Pump industry for nearly 20 years we have chosen carefully the brands we have allied ourselves with.

Having always been the most recommended specialist distributor of Heat Pump components from the technical schools of OEMs. We are now pleased to have established an equally as impressive reputation with the supply of Heat Pumps.

We have forged strong links with Vaillant, Midea, Ebac, Mitsubishi which complement our own offering, CTC, perfectly.  

With these alliances we can cover in depth the enormous range of buildings which require a sustainable heating solution, whether it be a small house boat with virtually no heating required, right through to a new industrial steel building or indeed stately home.

By understanding the value of the trust our customer base puts in us we have never and never will INSTALL. The same is not true of many distributors who are either installers with a bolt on distribution business or openly installing (in other words taking work from their own customers!)

Whether you are considering the first install or have been installing for years, Go Geothermal has the full technical knowledge and brand support in heat pumps to ensure your business has a dependable "Best in Class" offering.

Pipe manufactured specifically for heat collection
Available in coil sizes from 50m to 500 metres

PE100 RC Pipe (Resistance to Crack) - 5x Stronger than PE100/PE100+!!

Horizontal Collector - PE100-RC - THE NEW GENERATION OF GROUND SOURCE PIPE MATERIAL
The improved mechanical properties of PE100-RC and the demand for higher quality products has seen many European countries switch from PE100 to PE100-RC as their ground source pipework of choice.

Used extensively in mainland Europe PE100-RC Collector pipe offers superior impact crack resistance to PE100/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 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.

Sand has become the default position on most installs to act as protection from the variants of "as dug material".  Whilst reducing the thermal conductivity of the surrounding earth it also adds 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.

For the additional cost of PE100-RC pipe over our standard PE100 equivalent, the total installed cost can often be significantly cheaper than standard PE100 backfilled with a sand bedding.

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

Our European sourced Probes are manufactured from Virgin Grade Black PE100 High Performance Polyethylene. The pipe is manufactured according to EN 12201:2003 with the Probe Tip and finished product audited and certified by and according to the guideline by SK-Z Würzburg HR 3.26 and complies with the VDI 4640 & VBS 2011 guidelines.

All Probes are marked with the length stamps each meter, PN and SDR stamps, manufacturer name, and batch certificate with each individual Probe.

[Rehau Probe - From Go Geothermal Ltd]
Go Geothermal probes are designed to operate at a minimum of 25 years service life and as such the entire probe is accredited NOT just the pipe but the probe weld and foot.

Our probes are sourced from 30 year plus established multinational brands that specialise in Ground Source ensuring the assurances can be relied upon & trusted.

We also offer the only probe that comes with a CONSEQUENTIAL LOSS Guarantee for ultimate client peace of mind (see PE-Xa section below).

PE100-RC THE NEW GENERATION OF GROUND-SOURCE PIPE MATERIAL

- PE100-RC stands for Polyethylene Resistant to Crack
- The major benefit of PE100-RC probes is the increased point load resistance over PE 100
- Point loads are a potential problem as the probe does not sink in a straight line
- PE100-RC lasts longer on ACT test than PE100 (Accelerated creep test which is an artificial pipe ageing method)
- Many European countries have switched from PE100 to PE100-RC as their ground source pipework of choice
- The UK GSHPA has already included PE100-RC as a pipe material in their Vertical Borehole Standards
- All our PE100-RC Probes have SKZ certification (independent test house)
- Our Probes are 3rd party accredited

Ground-air Heat Exchanger system for controlled ventilation
Ever improving insulation and air tight construction of buildings means that controlled ventilation is becoming ever more important. The ground-air heat exchanger makes a considerable contribution to this, especially when used in conjunction with a heat recovery unit.

As well as increasing the quality of life within the building, this also provides significant energy savings by using the embodied ground energy to pre-condition the incoming ventilation air.

The ground-air heat exchanger takes advantage of the fact that the temperature of the ground, 1.5 to 2m deep, remains a relative constant temperature between 7°C -12°C throughout the year.

The incoming air passes through an undergound pipe system to pre-heat it in winter and to pre-cool in summer. Experience shows that a ground-air heat exchnager makes it possible to raise the temperature of air taken in by up to 9°C in winter, and to reduce it by up to 14°C.

Our British Made ECU is a fully automatic universal electrofusion welding unit, designed to join bar coded PE and PP pressure fittings in the range of 8v to 48v. It has been designed with simplicity of use in mind, and its fast user interface allows fittings to be welded quickly and reliably.Go Geothermal ECU.

The Go Geothermal ECU is designed for use in the UK and as such does not limit the user by "brand specific fittings use only" - many cheaper boxes particularly from Scandinavia are chipped to only work with a sole make of fitting. The GG ECU is compatible with all leading brands of UK and European fittings offering peace of mind when sourcing EF fittings from a variety of sources.
