Geothermal energyall year round
The FLINK dog house uses the earth’s geothermal energy thanks to its special design, allowing it to heat the walls in winter and cool them in summer without any external power source.
How does it work?
As we know, warm air rises while cold air sinks. We use this principle in the Flink geothermal dog house.

Structure
The structure of the house consists of polystyrene insulation elements designed with air gaps. The outer shell is painted, galvanized steel sheet.
For geothermal operation, a so-called ground heat exchanger is also required, which must be installed in the ground (not included in the package).
The following can serve as a ground heat exchanger:
KG PVC pipe (available at any plumbing or building services store)
Non-perforated plastic flexible protective conduit (shown in our installation video)
The system is assembled in 2 steps
Step 1:
The ground heat exchanger must be installed in the ground according to the installation guide.
To carry out the work, we recommend seeking assistance from a qualified plumbing professional.
Step 2:
The dog house assembled according to the assembly guide must be connected to the pipe ends above ground. The house can be easily assembled using a cordless screwdriver.
You can use it as a traditional dog house, or upgrade it to a geothermal dog house with heating and cooling
The Flink geothermal dog house is designed with air gaps in its structure, compared to the solid construction of traditional dog houses.
A ground heat exchanger can be connected to it, allowing the utilization of the earth’s thermal energy.
The ground heat exchanger does not need to be installed immediately. Without it, the house functions as a traditional dog house with excellent thermal insulation. Wall thickness is 10 cm.
In winter, the cooled air in the outer air gap flows downward into the ground heat exchanger due to the difference in density, warming up as it travels through the pipe. The warmed air then flows upward through the inner air gap. After passing through the roof structure of the house, it enters the outer air gap again, where it cools down and flows back into the ground heat exchanger. This creates a self-sustaining continuous circulation that ensures the tempering of the house even on the coldest winter days.
In summer, the airflow is driven by a low-power fan powered by a solar panel. In this case, the air cooled in the ground heat exchanger is blown into the inner air gap, pleasantly cooling the interior surfaces of the house. The air that warms up inside the walls flows back through the outer air gap into the ground heat exchanger, where it cools down again, thus circulating in a closed loop and cooling the house using only renewable green energy.

Frequently Asked Questions
How deep should the ground heat exchanger pipe be buried?
The performance of the ground heat exchanger depends on several factors. The most influential factors are the geographical location, soil temperature, moisture content, and the condition of the soil surrounding the pipe. These vary from area to area. Under average soil conditions in Hungary, the recommended pipe installation depth is 1.5–2.0 meters. The pipe should be installed at a minimum depth of 1.5 meters, but if possible, aiming for a depth of 2.0 meters will result in more efficient heat exchanger operation.
Is it worth installing the ground heat exchanger deeper?
It is possible, but we do not recommend installing the ground heat exchanger deeper than 2 meters, as the required earthwork becomes more significant while the increase in the exchanger’s efficiency is not substantial. It may result in a 1–2 °C increase in indoor temperature during winter and a similar decrease in summer.
If there is still a need to do so, it should be taken into account that the recommended pipe length may no longer be sufficient. In such cases, a pipe of appropriate length for the desired depth must be procured and installed.
When designing the product, our goal was to create a dog house with unique features that is able to provide a comfortable space for dogs using only renewable geothermal energy, in a self-sustaining and fully autonomous way. During the design process, key considerations included sustainability, simplicity, and creating a durable, long-lasting construction.
