GEROtop

What GEROtop does

GEROtop spol. s r.o. is a Czech engineering services and specialty equipment company founded circa 1998 and headquartered in Stráž nad Nisou (Liberec region), specializing exclusively in geothermal heat pump primary circuit design and implementation. The company designs and supplies ground-source heat pump systems — primarily vertical geothermal boreholes (50-300m depth, standard 100-150m), ground surface collectors, energy piles, and energy foundation slabs — for residential, commercial, industrial, and special-application buildings across the Czech Republic and Central Europe. Core proprietary components include GEROtherm GVS double-circuit probes in PE 100-RC material (certified 100-year lifespan) and the CALIDUTHERM EKO thermal grout (2.0 W/mK thermal conductivity), manufactured under a long-term technology partnership with Swiss-German plastics processor HAKA.GERODUR. The company pioneered Thermal Response Test (TRT) field testing in the Czech Republic in 2008 and employs 3D numerical modeling for multi-decade borehole field simulation.

GEROtop monetizes through three interconnected streams: (i) professional services including feasibility studies, primary circuit sizing, project documentation, technical review, authorial supervision, and operational monitoring, with free project design offered for small systems under 20 kW as lead generation; (ii) engineering services and supply for large-scale enterprise projects such as the ČSOB headquarters (179 boreholes, 1300 kW heating for 1,400 employees) and the Nebřenice ecological village (500 planned boreholes); and (iii) direct hardware sales through the EKG-GEROtop.cz e-commerce storefront launched in February 2017, distributing probes, piping, manifolds, fittings, and heat transfer fluids. Pricing for systems under 20 kW operates on a freemium model (free design) while equipment is sold at unit list prices excluding VAT, and large project contracts are priced by agreement.

Customers span four segmentation tiers: residential buildings under 20 kW (family houses, free design); medium buildings over 20 kW (schools, offices, hotels, apartment complexes); industrial facilities (production halls, warehouses); and special applications (aquariums, castles, sports halls). The sales motion is sales-led via regional technical-commercial representatives combined with a network of architectural studios and energy specialist partners who specify GEROtop into upstream projects. Notable reference customers include AZ Tower Brno (high-rise with energy foundations, 5-7 year payback), Vysoká škola báňská Ostrava (10 heat pumps, 110 boreholes, 650 kW), Matematicko-fyzikální fakulta UK (270 kW, annual savings of ~5 million CZK), TECO a.s. Kolín, and Sports Hall Dolní Břežany. Operating geographies are stated as Central Europe, with a strategic partnership with German firm Geoenergie Konzept.
