Design the source and the building together.

Equipment selection is one part of a geothermal system. The loop, distribution, controls and operating conditions need to work together.

Inputs to a project design.

Building demand

Use a project-specific heating and cooling load assessment, with the intended operating schedule and indoor conditions.

Source and distribution

Establish the design temperatures, flow requirements and available source conditions before selecting equipment.

Access and measurement

Plan isolation, controls, service clearances and the measurements needed to check operation.

Explore equipment types

Closed-loop options at a glance.

A geothermal heat pump exchanges heat with the ground or a body of water through a sealed loop of pipe. Vertical boreholes use the least surface area, horizontal trenches need more open ground, and a lake loop needs suitable water close by. Site conditions and the building’s loads decide which option fits.

Plan the installation
