Superior resilience and ability to withstand exceptionally high pressures

Geothermal is emerging as a rapidly expanding sector for Danfoss Heat Exchangers, providing an opportunity for engineering innovation to solutions tailored to geothermal plants, ultimately contributing to a reduction in fossil fuel consumption and CO2. Together with our long-term and trusted partner Geotermia Podhalańska in Poland, we are ready to take geothermal production to the next level.

Heating 1,900 private homes

Geotermia Podhalańska is a prominent player in geothermal energy for district heating utilities. The company emerged as a leading force in the field of geothermal energy to district heating utilities during the 1980s and 1990s.

This period marked the inception of the first buildings integrated into the geothermal heating network, coinciding with the establishment of Geotermia Podhalańska S.A., dedicated to leveraging hot water for commercial purposes.

By 1995, the company had successfully sold 18 TJ (terajoule) of geothermal heat, serving a network encompassing 27 customers.

Heat sales amounted to 533,316 GJ, with 1,563 heat consumers and 1,870 facilities connected to the network. The ordered capacity increased to 78,466 MW and heating up to 83°C. In 2022, 68 new facilities with an ordered capacity of 3,334 MW were connected to the heating network. Today, Geotermia Podhalańska provides heating to almost 1,900 private homes.

Interest in harnessing geothermal sources in Podhale emerged as early as the mid-19th century, with the renowned hot springs in Jaszczurówka near Zakopane capturing widespread attention.

These springs, characterized by their popularity, owed their existence to the infiltration of rainwater to profound depths. Here, the Earth’s heat acted upon these waters, warming them, and prompting their upward ascent through tectonic cracks under the influence of hydrostatic pressure.

Notably, despite the average annual air temperature in the region being 4.8°C, the waters boasted an average temperature of 18°C - a testament to the remarkable geothermal potential of the area.

In 2022, the geothermal system supplied 98.89% of the heat demand, with gas boilers meeting 1.08%, and oil boilers fulfilling 0.03% of the remaining heat demand*.

The outcome of this project has been remarkable, as it has augmented the capacity to produce heat from renewable sources by an impressive 6.71 MW, underscoring the project’s significant contributions to sustainable energy production and environmental success.

The collaboration between Geotermia Podhalańska and Danfoss Heat Exchangers started in 2019 when they requested a design for four 25 bar heat exchangers to benefit the maximum of geothermal energy seven kilometers below the surface.

In 2019, the project reached successful completion by enhancing the efficiency of primary energy utilization and curtail energy consumption by strengthening energy production from renewable sources.

The delivery, installation, and assembly of high-capacity heat exchangers from Danfoss have been implemented, each with a capacity of approximately 8 MW. In 2023, Geotermia Podhalańska was ready to expand and reached out to Danfoss Heat Exchangers.

The transformative power of geothermal energy shines brightly. Especially, in countries relying on fossil fuels for heating buildings. Its advantage is its independence from weather conditions and renewable nature. We look forward to contributing to your next geothermal project!

Sales Driver Zaur Kuteliya in Danfoss Heat Exchangers highlights:

“Geotermia Podhalańska expressed such satisfaction with our initial heat exchangers that they promptly ordered an additional four units when planning their expansion.

We supplied four S221 Titanium Alloy heat exchangers (AISI 316 TI) with a capacity of 31.2 MW (7.8 MW each). Geothermal applications require titanium plates due to their resistance to chloride.

The solution by Danfoss Heat Exchangers has demonstrated superior resilience to deformation and ability to withstand exceptionally high pressures – exceeding the capabilities of traditional titanium plates. As an additional advantage, they are cheaper than 100% titanium.”
