­Services

A compreh­ensive range of services are available for Clients whether it be considering Vertical Loop, Open Loop, Pond (lake) Loop or Horizontal Loop Systems. Different systems will suit different needs, different ground conditions and different limitations (available area for the loop installation). Equipment and experience combine to ensure the best service is offered in all key areas of geothermal exchange design, drilling and construction.

­

­Vertical Loop Systems

Are the ideal choice when available land surface is limited. Drilling equipment is used to bore small diameter holes from 20m to 100m.

Open Loop Systems

Utilize ground water as a direct energy source. In ideal conditions, an open loop application can be the most economical type of geothermal system.

Pond (Lake) Loop Systems

Are very economical to install when a body of water is available because excavation costs are virtually elminated. Coils of pipe are simple placed on the bottom of the pond or lake.

Horizontal Loop Systems

Are often considered when adequate land surface is available. Pipes are placed in trenches, in lengths that range from 30m to 120m.

Advice

Because the cost of drilling can often make a ground source installation economically unviable, it is important to get the right advice from the start. McMillan SDS, with their wealth of knowledge and expertise in key drilling techniques, can offer you the benefit of their expertise and experience when assessing the feasibility of a geothermal installation. Information on the following points can help in the decision-making. ­

­­What suits the site best – trenches or boreholes;

What the drilling costs are for the area;

How many bores might be required;

What are the best drilling methods and any potential risks associated with drilling in the area;

What grout mix might be suitable for the area and how this may affect the installation costs.
