A Quick guide to Groundsource

What is Groundsource?

The term Groundsource originates from two Greek words ‘GEO’ and ‘THERM’. The Greek word ‘geo’ means the earth whilst their word for ‘therm’ means heat from the earth.  Groundsource energy is derived from the heat of the earth.  Drilcorp have worked on many Groundsource boreholes ranging from domestic houses right through to universities and auditoriums such as The Royal Festival Hall, London School of Economics and Kew Gardens to name a few.

How does Groundsource work? 

The shallow ground, the upper 10 feet of the Earth, maintains a nearly constant temperature between 50° and 60°F (10°-16°C). Like a cave, this ground temperature is warmer than the air above it in the winter and cooler than the air in the summer. Groundsource heat pumps take advantage of this resource to heat and cool buildings.

Groundsource heat pump systems consist of basically three parts: the ground heat exchanger, the heat pump unit, and the air delivery system (ductwork). The heat exchanger is basically a system of pipes called a loop, which is buried in the shallow ground near the building. A fluid (usually water or a mixture of water and antifreeze) circulates through the pipes to absorb or relinquish heat within the ground.

In the winter, the heat pump removes heat from the heat exchanger and pumps it into the indoor air delivery system. In the summer, the process is reversed, and the heat pump moves heat from the indoor air into the heat exchanger. The heat removed from the indoor air during the summer can also be used to heat water, providing a free source of hot water.

Why use Groundsource?

Groundsource heat pumps use much less energy than conventional heating systems, since they draw heat from the ground. They are also more efficient when cooling your home. Not only does this save energy and money, it reduces air pollution.
