| Geothermal Technology in Great Britain |
Beneath the outer surface of the earth the temperature gradually increases the closer you get to the molten core. Geothermal technology permits the explotation of this thermal energyGround source heat is a different type of geothermal energy.At one or two metres under the surface, the temperature of the earth has a tendency to remain incessant, with one or two degrees of change between the air and surface temperature.
This recurring source of heat can be harnessed by ground source heat pumps.Ground source heat pumps work by removing the low temperature heat near the surface, which is between 8C and 14C in England. A heat pump is used to transfer the heat from the ground thru a pipe buried in the ground and full of liquid to take in the heat, which is then distributed to the heating system for a building. The potential for warm aquifer geothermal energy in Great Britain is constrained as most sources are too far away from major cities or aren't commerically exploitable. It's been used successfully by Utilicom Limited in Southampton since 1986. Ground source heat pumps The technology is commerically available, widely tested and already proved in Europe and North America. It has the capability to replace normal heating heating systems and is simply hooked up to existing radiator pipework in houses. Ground source heat pumps are also OK for commercial and business buildings.The DTI has guessed that there's the aptitude for 1,550 enormous commercial sites to use ground source heat pumps. According to the Energy Saving Trust report, domestic uptake of ground source heat pumps might be installed in 537,000 houses in the United Kingdom by 2030. This was only based on a comparison with electrical heating, and ground source heat pumps have the potential to go much further than this with the right support.The enlarging cost of gas, enhancements in technology and increases in production will make ground source heat pumps rather more competitive in future times. |
