Drilling
boreholes for geothermal energy is the most
difficult part of the Geothermal System
installation, mainly because the topography and
geology of Scotland’s west coast is as complex as
anywhere in the world, therefore selecting and
carrying out the drilling process to suit the
geological and site conditions is as important as
selecting the correct GSHP. Argyll Geothermal has
the equipment, the skills and the experience to
deliver a complete
drilling service for the geothermal market.
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. In cold
weather heat is absorbed from the earth and
transferred to the GSHP unit. The GSHP unit
amplifies the heat and delivers it indoors. In warm
weather the process is reversed, and excess heat is
carried from indoors and into the earth.
Open Loop
systems utilise
groundwater from a well as a direct energy source.
Simply run the groundwater via a borehole pump
through the GSHP unit.
Geothermal
and Energy Piles
In addition to the original
geothermal system where geothermal wells are used for heating only,
a newer system is now available to incorporate building foundations
– piles- as well as geothermal heating.
The use of geothermal energy
techniques integrated in structural pile foundations has the
capability of being an efficient and cost effective solution in
domestic and commercial building projects. Generally known as
structural energy piles, these systems use plastic piping transfer
heat from the ground to the building. Since the temperature within
the ground remains relatively constant, the circulating water
maintains a constant temperature throughout the year, providing a
safe, energy efficient and reliable heating system.
Effectively, geothermal piles
will reduce the need for traditional sources of heating and cooling
and will bring the idea of carbon-neutral buildings closer to
reality
