While the initial investment in a geothermal vault might raise some concerns, the long-term benefits far outweigh the upfront cost. Geothermal vaults offer significant time and cost savings for both project owners and installers, making them an essential component in large industrial and commercial geothermal systems.

Here are the top six reasons why incorporating a geothermal vault can enhance your next commercial loopfield project.

Top 6 Benefits of Geothermal Vaults for Commercial Projects

1 Maximize Space Efficiency
A geothermal vault can optimize space in mechanical rooms by reducing the number of pipes entering the building. By placing the manifold system outside, the vault:

• Minimizes core drilling through walls or foundations, preserving the building’s structural integrity.
• Creates additional room for critical system components such as pumps, controls, and electrical panels.
• Reduces the amount of time the loopfield contractor spends inside the mechanical room, ensuring smoother coordination with other trades and keeping the project on schedule.

2 Streamline Workflow with Scope Separation
A geothermal vault can optimize space in mechanical rooms by reducing the number of pipes entering the building. By placing the manifold system outside, the vault:

• It enables loopfield contractors to perform pressure tests, flushing, and purging without waiting for mechanical work to be completed inside.
• By integrating a bypass valve in the vault, the loopfield is kept isolated from supply-return lines, allowing mechanical contractors to continue their work without compromising the integrity of the loopfield.

3 Simplify Maintenance and Repairs
The vault’s design offers a practical solution for repairing damaged circuits or locating leaks without disrupting the building’s operations. By keeping the manifold outside:

• Loopfield contractors can diagnose and repair leaks quickly, using butterfly isolation valves on each circuit to isolate issues.
• The vault prevents spills inside the mechanical room, minimizing mess and operational disruptions.
• It also conserves resources like antifreeze and rust inhibitors by allowing isolated repairs to proceed without recharging the entire system.

4 Convenience and Efficiency with Prefabricated Vaults
Prefabricated geothermal vaults offer a hassle-free, “plug-and-play” option for contractors. Instead of building the manifold system on-site, the vault is preassembled off-site, allowing the contractor to focus on:

• Drilling and pipe installation while the vault is being manufactured.
• A quick, efficient setup once the vault arrives on-site, followed by straightforward connection and system testing, which prepares the geothermal loopfield for operation faster.

5 Accommodate Larger Distances from the Building
For projects with loopfields located far from the building—sometimes 500 feet or more—a vault acts as a central hub to collect the flow from the field. The vault design allows:

• A single, larger pair of supply-return lines to be run from the vault to the building, minimizing trench size and excavation work.
• Sizing of the supply-return lines to reduce head loss, ensuring that the distance between the loopfield and the building doesn’t become a limiting factor in system performance.

6 Prepare for Future Expansion
In projects with phased geothermal system installations, a vault can be designed with extra capacity to accommodate future expansion. By installing additional circuits upfront, the system can grow without significant disruption to the building’s interior, ensuring:

• Expansion of the loopfield with minimal disruption to ongoing operations.
• Simplified upgrades as the system evolves to meet changing needs.
