Vertical Loop Installation in Denver
Vertical loop installation places vertical boreholes and loop piping beneath your yard to provide the ground heat exchange for Geothermal Heat Pumps. This solution fits Denver metro properties with limited surface area, narrow urban lots, or yard conditions that block horizontal trenches, and it is the go-to choice when deeper heat-exchange capacity is required by a large heat load or by local geology.
In Denver the design balances freeze-thaw cycles, high-elevation heating demand, and the city’s variable soils. Borehole depths are determined by heat load and subsurface conditions; on many Denver sites boreholes commonly fall in the range of about 150 to 400 feet, but actual depth follows a site-specific soil analysis and heat-load calculation. Expect a written drilling scope that lists target depths, grout-sealing method, planned pressure tests, and an on-site staging plan. Drilling and grouting add cost and extend the schedule compared with surface loops. Rocky layers or shallow bedrock may require a different drill rig or alternate grout specification. Repairs to vertical loops typically need confined access and are planned for during design.
Before work begins, plan for a site evaluation that includes utility locates, a soil or geotechnical review, and a written estimate that separates drilling, grout sealing, and loop tie-in. Reasonable practical expectations are a clear drilling schedule, documentation of grout and pressure testing, and a commissioning checklist tying the vertical loops to the indoor Geothermal Heat Pumps system.
