Geothermal energy RAUGEO

The system uses the constant temperature of the ground via boreholes and a heat exchanger (probes) for heating in winter and cooling in summer.

It is environmentally friendly, energy efficient, and cheaper to operate in the long term due to the long service life of its primary circuit, i.e., probes (100 years +). In addition, it reduces dependence on fossil fuels.

Yes, this system is ideal for low-temperature surface heating/cooling systems such as underfloor heating or cooling ceilings. Of course, it can also easily handle radiator heating systems designed for lower temperature gradients for more efficient operation.

This depends on the size of the building, heat loss, geological conditions, and cooling requirements. Our configurator will help you calculate the optimal total length of probes.

Simply enter the basic data about your house, and the configurator will calculate the total length of geothermal dry wells required, including probes, and the approximate price of the system.

Some of the following parameters: heat loss of the building, heat output of the heat pump, type of building, living area in m², location, number of people in the household for hot water heating…

The price depends on the number of boreholes, the type of heat pump, and the overall installation. Our tool will give you a more accurate estimate of the price for part of this system, namely the primary circuit, which is the source of low-potential energy for the ground/water heat pump.

Deep dry drilling systems have higher initial costs but significantly lower operating costs. Savings can reach 25–70% per year, depending on the type of primary energy with which the system is compared (gas, electricity, wood, biomass, etc.).

Yes, support programs for renewable energy sources are often available. The SIEA (Slovak Innovation and Energy Agency) regularly provides information about current opportunities on its website.

Specialized drilling equipment will arrive at your property to drill and install probes to a depth of 80–150 m. The work usually takes 1–2 days per borehole (depending on the subsoil).

Yes, for wells deeper than 30 m, a hydrogeological assessment and notification/permit application are required. We can help you with this, or rather our partners in the field of drilling and geological work.

The PE-Xa probes installed in boreholes have a service life of more than 100 years, while ground-water heat pumps usually last 20–25 years.

Although the ground-water system requires a higher initial investment, its operating costs are lower – it uses stable energy from the ground, which is free. In addition, it is not as dependent on primary energy prices, i.e., gas or electricity for heating/cooling, thanks to its high efficiency, and offers long-term returns and energy independence.

Air source heat pumps are affected by outdoor temperatures – their efficiency decreases in winter when you need it most, especially during frequent defrost cycles (DEFROST mode), due to increasingly mild but humid winters. Their service life is also significantly shorter (10-15 years) due to their basic characteristic – outdoor installation with all the weather influences on their construction.

A ground-water heat pump draws heat energy from the surrounding subsoil, where the temperature is stable throughout the year, making it more efficient, quieter, and longer-lasting, thanks in part to the location of its main compressor section indoors.

Yes – in addition to being environmentally friendly and low-cost, this system has minimal maintenance requirements, long component life, and the option of passive/active cooling, which is particularly advantageous in increasingly hot summers. It is the future of heating, available today.
