Groundwater as a source of energy
Groundwater may be used as a source of heat. Ground source heat pumps are receiving increased attention as energy efficient commercial and residential heating/cooling systems. Although initial costs are higher than air source systems – due to the additional costs of the underground installations – the much greater energy efficiency of ground source systems makes them increasingly attractive.
Research into the use of geothermal water has been carried out in a number of institutions across Canada. The City of Moose Jaw has developed a geothermal heating system for a public swimming pool and recreational facility. Carleton University in Ottawa already uses groundwater to heat and cool its buildings. The Health Centre complex in Sussex, New Brunswick has been utilizing an aquifer for thermal energy storage since 1995.
