What we enable

Future-proof geothermal heat businesses

QHeat develops and delivers patented coaxial deep geothermal technology for large-scale heating, cooling and seasonal heat storage.

Our scalable system combines deep geothermal heat production with heat pumps. We support the technology with lifecycle services and shared expertise to improve project economics, reduce delivery risk, and maximise the geothermal system potential.

We have delivered five commercial heating plants and are expanding our partner model. We work with energy companies, real estate owners, and drilling partners to develop competitive, low-emission heat solutions built to last.

%

Areal density

Uses 97% less land area than traditional 300m deep ground source heating.

Technology

Heating, cooling and seasonal storage - all in one well

QHeat's heat well technology extracts and stores heat to a well system ranging from 1 to 2 kilometers in depth, providing stable, low-emission local heating year-round. Its coaxial design enables reversing the flow. Integrated with heat pumps, the system provides heating, cooling, and seasonal storage in urban environments.

Key benefits

Why companies choose QHeat

Self-sufficiency

Becoming an energy producer reduces dependence on complex supply chains. It ensures stable energy distribution, lowers costs and improves environmental performance.

Clean and flexible energy

QHeat’s technology is ideal for dense urban areas. A single deep well can provide clean heating and cooling for an entire block, while adding flexibility to the overall heating system.

Energy efficiency

Steadier, higher temperatures from the well increase heat pump efficiency and reduce electricity demand. As ground temperatures are unaffected by weather, this advantage is maintained even during the coldest months.

Increased property value

Low-emission heating and cooling increase property value and future-proof your assets.
