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

Vertical, horizontal or lake loop.

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

How a geothermal job goes.

Three parts: the loop field outside, the pipe that connects it, and the equipment inside.

Drilling the loop field.

We look at the ground, the access and the building load first. That decides how many boreholes and how deep, or whether a horizontal or lake loop fits better.

Connecting the loop. Supply and return lines run from the loop field into the building. The loop is pressure tested before it is buried. Understand the system

Piping the plant room. Inside, the loop meets the pumps and the heat pumps. We pipe in hard copper, and in steel on some commercial plants. Explore commercial projects

What we check before we quote.

Before the drill arrives

Review site access, underground services, available ground or water, geology, permissions and the building load. Borehole depth and field size require site-specific design.

At the building connection

Define the source-side pipework, pumping, electrical work, controls, distribution changes and commissioning records. Agree who owns each part of the installation.

For a retrofit

Document the current heating system, peak loads, supply-temperature needs, electrical service and workable phasing before deciding what can be retained.
