Geo thermal drilling
WHAT IS GEOTHERMAL HEATING?
The earth's temperature remains fairly constant, at fairly shallow depths below the ground. A Geothermal ground source heat pump (GSHP) unit pulls the heat from under the earth, removes it, then it heats up by compressing it, then it will evenly distribute the heat throughout the building to warm it through during the winter months. With a flick of a switch, the same system will then pull heat from your building during the summer months and transfers it back into the earth; this provides the air conditioning of your building.
The system doesn't operate by heating or cooling air with fuel; instead it moves heat from the ground up to the building or vice-versa. Heat pumps are a better alternative than burning scarce and expensive non-renewable fossil fuels. This is an inexhaustible source of energy.
No matter where you live, Geothermal systems are 100% capable of supplying your heating and cooling needs.
A geothermal ground source system is 6 times more efficient than using conventional fossil fuel heating and cooling methods and it has huge environmental advantages – by drilling a borehole into the ground and using geothermal energy, no fossil fuels are required.
They offer significant advantages over conventional heating systems:
• Significant reduction in CO2 emissions
• Lower running costs
• Safer – no combustible sources
• Minimal inspection and maintenance
• No fuel handling or storage
• No emissions or operating noise
• Reduced plant room requirements
• Long lifetime
• No exposed external units
Open Loop systems use groundwater from a Borehole as a direct energy source. The ground water runs via a pump through the GSHP unit boosting the temperatuture then running the cooled water away to waste
BOREHOLE GEOTHERMAL SYSTEMS:
Closed Loop systems circulate a water-based solution through a small diameter "loop" underground pipes in boreholes usually 40 – 100m in depth, the loop is surrounded with thermally enhanced borehole grouting products designed to maximise the borehole efficiency. During the cold weather months, heat is absorbed up from the earth and transferred to the GSHP unit. The GSHP unit will then amplify the heat and transfers it indoors. In the warm weather months the process is then reversed, any excess heat will then be carried from indoors, back into the earth.
The borehole water can also be used to supply your domestic water needs.
