Heat, steam, cooling, fresh water.
A single well is a heat source whose supply temperature you design. What it feeds is an engineering decision, not a property of the source. These are the applications we build for.
Where the heat goes
Five families of application, one system underneath all of them.
Buildings, pools and district heat
Swimming pools, hotels, hospitals, care homes, offices, greenhouses and small district networks. Between 25 and 45 °C straight from the well, higher with a heat pump. Bredene is the built example: pool, sports hall and showers from one borehole.
Industrial process heat
Drying, washing, evaporating, pasteurising, pre-heating. Most industrial heat below 150 °C is still made by burning gas. A single-well system delivers it continuously, on the site that consumes it, with no weather dependence and no fuel price attached.
Steam
Where the formation is hot enough and the well deep enough, the same principle raises steam for process industry. Depth is the design variable that decides whether steam is on the table at a given site.
Cooling and seasonal storage
In summer the loop runs the other way: the well takes heat out of the building and parks it in the rock, where it is available again in winter. Cooling and heating from one asset, and a better balance for both.
Desalination
Thermal desalination runs on exactly this grade of heat. On coasts that have sun and salt but no gas grid, a single well can drive fresh-water production without fuel and without a power connection large enough for reverse osmosis.
Scalable in two directions
A single well is not a fixed size. It is sized to the demand in front of it — and there are two independent dials.
Couple more wells
Wells are modular. Two, five or twenty of them on one manifold and the installed capacity grows with the site. Every well stands on its own, so there is no minimum field size and no step change in subsurface risk when the project gets bigger. Any energy demand can be met by adding wells.
Match the depth to the demand
The depth of the installed system is a design variable, not a given. Shallower where a low supply temperature is enough, deeper where the process needs more. The demand sets the depth, so the capital cost follows the requirement instead of a standard field layout.
How a project starts
Four steps. After the first two we can already tell you whether a single well fits your site.

First: the load
What do you need, at what temperature, and for how many hours a year? The load profile is the starting point — not the geology.
Then: the subsurface
Public data and, where they exist, nearby well logs give the temperature gradient and the thermal properties of the rock. That is enough for a first yield estimate without drilling anything.
The design
Depth, well diameter, string configuration, flow rate and the number of wells. This is where the two scaling dials are set against your load.
Build and deliver
We design the system, manage the drilling and the installation with our partners, and connect it to the building or the process. Bredene went from spud to delivery in one winter.
