Is now a good time to invest in geothermal heat pumps for your home or business?

Dig Energy has finished drilling seven boreholes at the Boston headquarters of Suffolk Construction. The company utilizes a high-pressure water system to perform the work.

Why it matters

Traditional drilling methods often make ground-sourced heat pumps prohibitively expensive to install. Dig Energy aims to lower these barriers by using water instead of heavy metal rigs to access geothermal temperatures.

Dig Energy claims its water-based process reduces overall drilling costs by 75 percent. The recent project in Roxbury attracted 80 visitors to the drill site.

The players

Dig Energy

This company develops water-based drilling technology for ground-sourced heat pump installations.

Suffolk Construction

This major construction firm hosted the recent drilling project at its Boston headquarters.

The details

The technology works by using a stream of high-pressure water to grind away rock and dirt, while a jet pump simultaneously removes debris back to the surface. This method avoids the need for traditional, heavy metal drilling rigs.

Dig Energy was founded in 2020.
The project in Roxbury was completed in September 2026.

Market Landscape

The transition to sustainable heating relies on the affordability of ground-sourced heat pumps. By bypassing traditional heavy machinery, the firm positions itself against established drilling companies with a lower-cost, mobile alternative.

Lower drilling costs could eventually lead to more affordable residential and commercial heating installations for property owners. Customers may see increased availability of geothermal solutions as the company scales its operations.

The takeaway

Advancements in drilling technology are essential for reducing the financial barriers to renewable energy adoption. Implementing water-based excavation may allow contractors to complete complex infrastructure tasks with significantly fewer resources.
