Drilling & Groundworks
Geothermal International's specialist in-house Drilling division is at the forefront of heat pump installation and is able to undertake all aspects of ground preparation for our clients. We offer the full range of collectors and will design the system that fits best with the available land or water source, the local geology and the heating requirements. The different types of collector are described below. For new build projects, energy piles can be incorporated into the building design. With some of the heat pump pipes incorporated into the piles the need for further drilling and groundwork is significantly reduced.
Closed vertical loop
The ideal choice when available land surface is limited. Drilling equipment is used to bore small-diameter holes from 50m to 150m deep.
Open loops
Open loop systems utilise ground water as a direct energy source. In ideal conditions, an open loop application can be the most economical type of geothermal system.
Horizontal loop
Often considered when adequate land surface is available. Pipes are place in trenches in length that range from 30m to 120m.
Pond (lake) loops
These are very economical to install when a body of water is available because excavation costs are virtually eliminated. Coils of pipe are simply placed on the bottom of the pond or lake.
