Insulation System
Geothermal energy
The system uses the stable temperature of the earth to naturally regulate indoor climate. Warm or cool air flows continuously through the wall cavities, heated in winter and cooled in summer, reducing energy loss.
Technology
A unique combination of insulation panels and a buried heat exchanger allows efficient energy transfer from the ground to the building. This design is legally protected and proven in experimental structures.
Advantages
Even without any external energy input, the building reliably remains above freezing throughout winter. This ensures stored goods, animals, and equipment are fully protected with zero heating costs.
Energy efficiency
The innovative technology significantly reduces both heating and cooling energy demand for comfortable living spaces. Ground-sourced air circulation efficiently smooths temperature fluctuations.
Patented Geothermal Insulation System
A patented insulation system that harnesses the geothermal energy of the ground to reduce heat loss in comfortable buildings and prevent freezing in unheated structures, by circulating air through cavities built into the walls.
The system consists of polystyrene insulation panels and a plastic tube – the so-called ground heat exchanger. The heat exchanger is installed in the ground according to technical specifications, with the above-ground pipe ends connected to the multi-layered insulation integrated into the building. Air flows through the wall cavities, warmed in winter and cooled in summer by the ground heat exchanger.

Frost-Free Protection Without External Energy
If an unheated building requires only frost protection, the system ensures a consistently frost-free environment completely on its own, without relying on any external energy sources.
Reliable Winter Safety and Energy Savings
This self-regulating mechanism keeps the interior above freezing throughout the winter, providing reliable protection for stored goods, equipment, and structures while eliminating additional energy costs.
Project Overview
In practice, this means that after the insulation system is installed, the building’s heating energy demand is completely eliminated while the indoor temperature remains above 0°C. As a result, the energy previously required to maintain frost-free conditions can be fully saved, providing a direct financial benefit to the operator.
The system may also be suitable for reducing winter heat loss in comfortable residential buildings and for mitigating summer heat load. In such cases, achieving the same comfort level requires significantly less energy for both heating and cooling.
To verify the operation of the technology, we created two simple experimental structuresImplemented examples
Frost-Free Test House
We built a structure with a 1×1 meter footprint and a height of 1.5 meters, equipped with the geothermal insulation system. During winter testing, with an outdoor temperature of –15 °C, the internal temperature never dropped below 0 °C—all without any heating or external energy input.
This technology is particularly suitable for buildings where the primary goal is to maintain frost-free conditions. The system uniquely achieves this using only geothermal energy, eliminating the need for a dedicated heating system. As a result, significant installation costs are avoided, and operation requires no ongoing energy expense.
Application Areas
- Livestock buildings
- Storage halls
- Mobile garages
- Vegetable and fruit storage facilities
- Highway rest-area sanitary blocks
- Thermal protection for utilities and mechanical systems
Flink Geothermal Dog House
This prototype represents a standalone, commercially developed product that also uses geothermal insulation technology. Due to its larger door opening, it cannot maintain complete frost-free conditions; however, this level of protection is generally not necessary for a dog’s well-being. The structure still provides significant thermal stability compared to conventional dog houses.
The Flink dog house clearly demonstrates the system’s impressive thermal buffering capabilities. During the winter months, the dog not only warms the interior with its own body heat but also benefits from continuous natural geothermal support, creating a noticeably more comfortable environment.
Additionally, the built-in fan allows the system to draw air through the ground heat exchanger for cooling, providing effective temperature reduction during hot summer periods and ensuring year-round comfort.

Project Roadmap and Patent Status
Project Roadmap and Patent Status
Building on the examples above, our goal is to optimize the efficiency of the technology, develop a scalable sizing method, construct a working prototype, and validate the system through measurements and calculations. In parallel, we aim to prepare the technology for broader use within the construction industry.
The system is already protected by valid patents in the European Union (EP 3 645 802), the United States (US 11,619,404), and Hungary (HU 231 047). In Canada, the patent application process is currently underway (CA 3,103,647).
Project Timeline:
- March: Prototype construction and completion of basic functional tests
- July: Detailed research and development phase, including field measurements in summer conditions
- August: Distribution of digital rewards and thank-you letters to our supporters
- End of year: Physical prototype demonstration and testing for supporters, along with winter field measurements
- March (following year): Full project completion, publication of results, and development of future plans
Important: While we strive to meet all deadlines, the nature of research and development may lead to unavoidable delays. Should this occur, we will notify all supporters in a timely manner and provide detailed updates about the progress.

Patent Protection & Partnership Opportunities
The technology is already protected by patents, ensuring its uniqueness and market potential.
Maintaining these patents requires ongoing fees — for which we also seek the support of our community.
We are open to strategic collaborations as well: we welcome partners who, through long-term and continuous support, would gain exclusive rights to participate in the commercialization of the system.
Our Commitment
Important Notice:
If the full funding amount is not reached, or if we are unable to achieve our goals in their entirety, we unfortunately cannot refund contributions, as all funds are continuously used to advance the project.
However, we are fully committed to reaching our objectives, and we guarantee that every contribution will be spent exclusively on development: research, prototype construction, measurement programs, and patent maintenance.
Every supporter’s contribution matters — each one brings the project a significant step forward.
How does it work?
By supporting this initiative, you’re not only helping bring an innovative geothermal insulation technology to life — you’re also playing a key role in launching a new direction in modern building practices.
