G-Stow - Geothermal Borehole Heating Systems
A geothermal ground source system is shown to be six times more efficient than conventional fossil fuel heating and cooling methods, with huge environmental advantages – by drilling a borehole into the ground and using geothermal energy, which is available everywhere, no fossil fuels are required.

G STOW PLC is an established market leader in the rapidly expanding field of geothermal energy, geothermal borehole drilling and supply of complete geothermal systems. Providing the highest levels of expertise, service and health and safety for commercial and domestic projects.
As specialists in geothermal borehole design and construction, we will handle all aspects of the installation from conception to completion, including licensing, testing and commissioning.
What is Geothermal Energy?
Geothermal energy is heat – a natural, renewable resource which is obtained from the earth. This energy can be used to provide extremely efficient, high quality heating and cooling in both commercial and domestic buildings.
It is an important alternative to burning scarce, costly and non-renewable fossil fuels and has enormous potential as a major world-wide energy source.
Geothermal energy is found at relatively shallow depths below the ground, where the earth’s temperature remains fairly constant, and is processed utilising a geothermal borehole system.
The heart of the system is a geothermal ground source heat pump, which extracts heat from under the earth. This is then evenly distributed throughout the building, providing comfortable heating even in the coldest winter. To cool the building in summer, just the flick of a switch reverses the process, and excess heat is drawn away and transferred back into the ground, completing the cycle of renewable energy.
Geothermal systems are fully capable of supplying 100% of your heating and cooling requirements, in most situations and in any area. A geothermal system can also provide inexpensive hot water.
With very low operating costs and efficient use of energy, geothermal systems achieve a constant high rating by users, who find them superior to conventional heating and cooling systems.
Recent environmental legislation now encourages the use of new “green” technologies and innovative sources of energy into new projects, with geothermal energy at the forefront, and growing rapidly as the preferred alternative choice for heating and cooling systems in buildings.
Geothermal Borehole Systems
Geothermal systems consist of open and closed loop borehole configurations depending on particular requirements and geology.
Open Loop Geothermal Borehole Systems
Open Loop systems use groundwater from aquifers beneath the site.
Two water boreholes are installed – one to pipe water to the building where it transfers its heat to a heat exchanger. The water is then returned to the same aquifer via the second or ‘recharge’ borehole.
Depending on the size of the building multiple boreholes may be required.
Please just give us a call if you would like to chat to us about the logistics of a system in more detail.
Closed Loop Geothermal Borehole Systems
These are continuous loops of pipe buried in the ground, (or in a pond or lake), containing an environmentally safe solution of water and antifreeze which circulates through the system.
Horizontal Closed Loop Geothermal Borehole Systems
This type of installation is generally specified where sufficient land is available, where the pipes are laid in a number of trenches.
Vertical Closed Loop Geothermal Borehole Systems
Often specified for large commercial buildings and schools, where the land area required for horizontal loops would be prohibitive. The pipes are installed in deep boreholes and are also used where the soil is too shallow for trenching, as they minimise disturbance to existing landscape.
