- How It Works
How does a geothermal heat pump work?
A geothermal heat pump extracts heat from the ground, where the temperature remains stable throughout the year. This energy is channeled to the heat pump via a closed-loop system and converted into usable heat for heating your home, providing hot water, or heating your pool.
Thanks to this principle, the system operates extremely efficiently and is not affected by the outside temperature. In addition, energy-efficient (passive) cooling is also possible.
- Advantages
Why choose a
Ground-water heat pump?
A ground-water heat pump is one of the most efficient heat pumps available on the market.
Long service life
Components are less exposed to the elements and wear and tear. A ground loop can easily last more than 50 years.
Stable returns
The ground temperature remains virtually constant throughout the year, allowing the heat pump to operate more efficiently. This results in a higher COP/SCOP and lower energy costs.
Silent as a whisper
Because there is no outdoor unit with a fan, the system operates virtually silently. This enhances living comfort and prevents noise pollution.
Passive cooling
The natural coolness of the ground can be used to cool the home in an energy-efficient way. The compressor remains off, which keeps energy consumption to a minimum.
High efficiency
A ground-source heat pump maintains its efficiency even in freezing weather. As a result, less supplemental electric heating is needed.
EPC value
A ground-source heat pump significantly contributes to a lower EPC score thanks to its high seasonal efficiency. This has a major impact on the home’s market value.

- Step by step
How we operate:
From Analysis to Implementation
A geothermal project requires precision at every stage. Thanks to our thorough preliminary study and cost analysis, we guarantee technically optimal execution.
Site Visit
Every geothermal installation begins with a technically sound preliminary study. We analyze the heat demand, soil conditions, available space, and project requirements to determine the exact dimensions of the wellfield. During the site visit, we validate these calculations and carefully map out accessibility, drilling locations, and points of concern.
Vertical Drilling
The drilling is carried out according to the predetermined drilling plan. The depth, configuration, and positioning are perfectly aligned with the heat and efficiency calculations. This is essential for stable energy absorption and optimal operation of the heat pump. The duration of the work varies depending on soil conditions and project complexity.
Connecting the ground circuit
The vertical probes are hydraulically connected and routed to the utility room. The closed-loop system is filled with a water-glycol mixture to ensure efficient heat transfer and freeze protection. Pressure tests and inspections ensure the system’s reliability. This loop forms the basis of the installation.
Starting Up the Heat Pump
The heat pump is connected to the ground loop and the distribution system. During startup, we check flow rates, temperatures, and system pressures. Thanks to the precise preliminary analysis, the system operates within optimal parameters. This results in maximum efficiency and comfort.

- FAQ
Frequently Asked Questions About Heat Pumps
Can you cool a room with a heat pump?
Yes, both air-to-water and ground-to-water heat pumps can also cool your home in the summer.
- In an air-to-water heat pump, this is achieved through active cooling, during which the system operates in reverse mode.
- With a ground-source heat pump, passive cooling is often possible as well, utilizing the natural coolness of the ground.
Important to know: A heat pump’s cooling capacity is less intense than that of a traditional air conditioning system. You shouldn’t expect a temperature drop of 10°C, but rather a pleasant reduction of a few degrees, which is often enough to ensure comfort on hot days. It’s ideal when combined with underfloor heating or fan coil units that are also suitable for cooling.
Does a heat pump also work in combination with high-temperature heating systems?
Heat pumps are most efficient when used for low-temperature heating systems, such as radiant floor heating or modified radiators.
But we also offer high-temperature heat pumps with a supply temperature of up to 70°C. They’re ideal for replacing your gas or oil boiler and work perfectly with your existing radiators.
Please note: these systems may consume more electricity than standard heat pumps. When renovating, we’d be happy to work with you to determine whether your existing heating system is compatible or needs to be replaced.

Do I need a permit for a heat pump?
In most cases, you do not need a permit to install a heat pump in your home. There are, however, a few exceptions:
- Ground-water heat pumps (with vertical boreholes) usually require a notification or permit from the Flemish Environment Agency, because drilling takes place underground.
- Air-to-water heat pumps generally do not require a permit, but you must take noise standards into account (especially if the outdoor unit is located close to a property line).
In the case of new construction or major renovations, the heat pump must, of course, be included in the EPB report.
How loud is a heat pump?
The noise level of a heat pump depends on the type of unit and where it is installed:
- An air-to-water heat pump has an outdoor unit that makes noise, similar to an air conditioner. At a distance of 5 meters, the noise level is usually between 35 and 50 decibels (comparable to a soft murmur or a refrigerator). Inside, you generally won’t be bothered by the noise, since the indoor unit operates very quietly and is usually installed in a storage room or utility room.
- A ground-water heat pump operates almost silently because it does not require an outdoor unit.
