Introduction to Go Geothermal

Go Geothermal are the true embodiment of the one stop shop for all things Ground Source. The entire offering from GG has

evolved from working closely with our customer base giving you the customer what you expect and need from a dependable

source has been paramount from inception.

Owner operated and proudly independent we have experienced overwhelming support for large stock levels and innovative and

market leading products. Whilst competitive prices are a pre requisite for any successful business, always being at the forefront

of new products, exceeding customer service expectations and high stock levels have proved just as key in this relatively new

market place.

Being a specialist allows us to stock the more unusual items and also have the confidence to promote and introduce new ideas

not bound by all the red tape of large multi nationals. It also leads to a far higher level of knowledge and service when you call,

something vital if you are in a new industry or equally if you are pushed for time, where service after care is equally important

our people can help and if they don’t know the answer they will know where to find the answer!

In a future type market you need a partner that keeps ahead of the pack with an in depth knowledge and partnership with the

leading manufacturers in GSHP technology. Go Geothermal work hard on your behalf to constantly source the latest

innovations and developments within the UK and Europe.

All this but with a firm commitment to never source from outside Europe so as to ensure ethical sources for your clients whilst

also minimising the carbon footprint. We always source from within the UK whenever feasible and will always be happy to list

the considerable range we do source whenever you call!

This brochure is merely a flavour of the range you can expect to find ex stock at Go Geothermal. As such the online document is

updated weekly and as such we ask you to regularly visit our website.

In the meantime we look forward to hearing from you soon and hope that we will be able to demonstrate how we differ from

the crowd!

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

Preinsulated Header Pipe

able to handle temperatures up to 95°C (perfect for excess heat storage such as solar -

increasingly required feature of new builds); the PE-Xa really is the next generation of probes.

Furthermore, such is the strength and durability of the PE-Xa probes we are able to offer a

£10,000 consequential loss per PE-Xa probe installed. Contact us for more details.

Advantages of the Raugeo PE-Xa Probe:

• No need for joints in the soil ensures highest operational reliability

• PE-Xa material is not sensitive to notches and grooves

• Optimal safety during insertion into the borehole

• Simple insertion even into the tightest boreholes

• Constant operating temperatures -40°C to 95°C

• Stable up to temperatures of 95°C, thus the RAUGEO PE-Xa probe can be used for

heat storage purposes

• Extremely tight bending radii

• No need for sand backfill, simply use as dug material. – Thereby reducing

requirement for lorries carrying imported backfill

• Probe base is protected by a special tough resin

• Can be connected by means of Electrofusion sleeve or by means of REHAU – compression sleeve under all climatic

conditions.

• Residential or Commercial - Geoexchange cooling / heating system or ground energy storage (solar energy, waste heat)

Turbulence PE100 Collector Pipes

A uniquely designed product enables a greater heat absorption capacity and lower pressure drop.

Calculated at 10% greater heat absorption this increases the COP, makes the Heat Pump more

efficient therefore reducing running costs.

Probe/Ground Loop Feeder

Hydraulic loop feeder to assist with the safe and controlled installation of 40mm borehole probes (32mm made to

order). Comes with the following benefits over traditional hand pushing installation techniques:

• Allows the safe installation without staff standing on the drilling rig or other

platforms on site (working at height).

• Saves labour by reducing the need for additional staff at the time of loop installation.

• Allows additional controlled pressure to be applied to probes when inserting into

boreholes with a drilling fluid.

• Variable speed allows controlled insertion of probes where the weight of the probe

wants to fall into an open borehole reducing probe tip damage.

• Can assist with the removal of a probe where the borehole collapsed at depth and

the borehole will require re-drilling. This protects the operative from strain.

• Can also install and remove grout lines when using a liquid grout to backfill

boreholes.

• Compatible with most geothermal drilling rigs.

• Designed for drillers by drillers.

• Saves money.

• Fully adjustable.

• Hard wearing.

• More efficient than traditional hand pushing installation technique.

Radial Drilling

Radial drilling offers the client wishing to exploit the solar energy stored in the ground but short of

space another solution.

The benefits of Stable ground temperatures are well known but often lack of land prevents the

adoption of ground Source.

Radial drilling uses a centralised chamber with a minimum site footprint sending probes out

diagonally 30-65deg typically thus avoiding space restrictions.

Speak to us for further details on this specialist technology including our Rehau Coaxial Probes.

RAUGEO Energy Piles

Energy piles provide a cost-effective alternative to probes if the building is already including foundation piles as no extra drilling

needs to be carried out. Piles are typically between 10-20m deep, depending on site conditions. Ground-source pipework can

simply be integrated into the pile with cable ties.

PE-Xa is ideal for energy piles as the tight bending radius of PE-Xa removes the need for joints in the pile, therefore eliminating

any potential leakages.

Helix Probe

Raugeo Helix Probes PE-Xa are ideal for use in both new builds and refurbishments. They

are the optimum choice if only a small land area is available and probe drilling is not

possible, e.g. for geological reasons or if it is not financially possible.

A 5m deep hole is created with an Auger drill, into which the Helix probe is then installed

and backfilled. The distance between each probe is 3 - 4m. The specially designed PE

membrane ensures the fixed diameter of the probe facilitating even energy extraction.

High – Quality PE-Xa material means high resistance to puncture loads and elimination of

any joints due to small bending radius.

The high temp resistance of up to plus 95deg C makes a combination with solar energy possible – even retrospectively.

Making excess heat storage a reality in this increasingly required feature of new builds.

The advantages of the Raugeo Helix Probe PE-Xa:

• Use in new builds and refurbishments

• Extraction performance of up to 700 W/Helix Probe in Sandy clay (Wet)

• Simple and cost effective drilling possible

• Ideal where space is at a premium

• Defined pipe spacing and probe diameter using special PE membrane

• The high temp resistance of up to plus 95deg C makes a combination with solar energy possible – even retrospectively

Chambers

GeoSTACK Chamber

Whilst the GeoSTACK is of a comparable cost to that of traditional methods

such as concrete or brickwork the overall project cost saving is considerable.

The chambers can be built by non-specialist labour, require no lifting

equipment on site, are at full strength from the moment of installation and

fully conform to manual handling regulations. A typical installation of a

1220x600x900mm deep chamber will take no longer than 2 hours, including

backfilling, whereas a concrete or brickwork chamber can take anything up to

4 days to complete.

Developed for quick installations, even in the most difficult location, the

GeoSTACK underground access chamber system is used by many industries

due to its immense strength, light weight, adaptability and dramatic project

cost saving.

Design

The GeoSTACK access chamber consists of four modular panels that are bolted together in each corner to form an easy to

handle, robust, 150mm deep chamber ring. A finished chamber is produced by simply stacking the rings to the required depth. You can even retrospectively increase the height of an existing installed chamber!

The ribbed structure design improves chamber performance through efficient material usage and resists both vertical and lateral

applied loads. The GeoSTACK provides a full 76mm width-bedding area for the access cover and frame as required in the

Highways Agency Design Manual for Roads and Bridges - HA104/02.

Material

GeoSTACK access chambers are manufactured in DMC (Dough Moulding Compound) and SMC (Sheet Moulding Compound),

which are a mixture of polyester resins, glass fibre and fillers. These materials are typically five times stronger than

thermoplastic alternatives and are resistant to many acids, alkalis and aggressive water and soil.

Testing

Our GeoSTACK solutions have been rigorously tested by third party UKAS accredited test facilities.

Sizes

The following sizes are Height configurable in 150mm steps, i.e. 600mm, 750mm etc

900mm (L) x 600mm (W)

Sentinel R100 Solar Thermal Fluid is a clear blue liquid based on propylene glycol solution. It has been designed for use as a

thermal fluid in solar heating equipment such as flat plate and vacuum tube collectors where it ensures highly efficient heat

transfer between the solar collector and the thermal store. Sentinel R100 is also optimised to provide freeze protection of the

circuit even to –25°C.

The special inhibitors contained in Sentinel R100 provide superior protection to the metals normally used in solar installations

against corrosion and deposits. Sentinel R100 prevents the surfaces of heat exchangers fouling and maintains thermal efficiency.

The product is especially formulated to resist thermal degradation and so extend fluid life.

The efficient thermal transfer properties and superior stability of Sentinel R100 help towards reduced cost of system operation.

Sentinel R200 - Solar Cleaning Solution

Ready-to-use cleaner for solar heating systems

Features and Benefits

• Ready to use - no need for dilution

• Removes sludge and deposits from degraded thermal fluid

• Cleans with only 20 minutes circulation

• Effective at low or room temperature

• Can be used with flushing machine

• None foaming and easy disposal

• Compatible with the construction materials of the solar system

Properties

Sentinel R200 is a specially formulated, mildly alkaline product designed for use as a cleaner for solar heating system circuits

containing either flat plate or vacuum tube collectors.

The thermal fluids used in solar heating systems may degrade over time because of prolonged exposure to elevated

temperatures.

This degradation process, which is indicated by a darkening of the fluid, not only reduces the lifetime of the thermal fluid, but

also has the following adverse effects on the operation of the system:

• Colour changes and viscosity increases

• Thickening of the fluid and solid deposits which causes blockages

• Reduces the diameter of the pipe work

• Freezing point increases

• pH decreases

• The degraded fluid has a reduced heat transfer capability

In order to restore the efficient operation of the solar heating system it is necessary to drain the degraded thermal fluid, clean

the system to remove any sludge, deposits or blockages, and refill the system with Sentinel R100 - a thermal fluid which is

especially formulated to resist thermal degradation and so extend fluid life.

Final Word

Some people favour geothermal grouts featuring cement. We have kept clear of this because of the risk that future ground

movement or drying out of a rigid pile of grout could lead to the double-whammy of:

a) Loss of contact between the ground formation and the grout and or the grout and the loops and hence total break of

conductivity.

b) Contaminated surface water running down the gap between the formation and the rigid pile.

been designed with simplicity of use in mind, and its fast user interface allows fittings

to be welded quickly and reliably.

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.

The unit is built in a strong lightweight metal housing to protect it from damage. It has a

carrying handle for ease of operation and tough rubber cables that are suitable for use on

building sites. It is fully sealed and waterproof to IP65. It is suitable for use with portable

generators and is electrically protected to Class 1.

The unit has a simple button pad that allows quick navigation through the operating

menus. Information is shown on a bright four line display that can easily be read in all

lighting conditions. A range of display languages is available to allow the unit to be used

more easily throughout the world.

The unit is designed to weld Bar Code fittings up to 250mm diameter. The fitting terminal pins can be either 4.0mm or 4.7mm to

allow greater flexibility. The welding time is compensated for the ambient temperature, and fittings with voltages between 8V

and 48V can be welded. A manual weld option is available.

The unit will display fault finding and calibration information from the menu options to allow errors to be quickly diagnosed.

Programmable service intervals can be set to make sure equipment stays in good working order.
