HERZ

What HERZ does

HERZ d.o.o. is a Slovenian privately held limited liability company (d.o.o.) headquartered in Šmartno pri Litiji that manufactures sanitary fittings, valves, and plumbing products under the international Herz Group umbrella. The company was formed through the merger of two heritage Slovenian firms: UNITAS ARMATURE, founded in 1933 to produce sanitary fittings, and KOVINA, founded in 1951 to produce valves and fittings with proprietary development and European-standard compliance. Products are distributed internationally through the Herz Group's network spanning 75 countries, with related entities Herz Armaturen (Austria, regulation technology) and Herz Energie (Austria, biomass energy) operating under the same corporate umbrella.

The company's core product technology centers on the HERZ Sanitary Water Manifold (Razdelilnik za sanitarno vodo), a modular hot/cold water distribution system developed by the in-house R&D department led by Andrej Savšek. The manifold features G3/4 inch thread compatibility, pre-installed O-ring seals, support for 2/3/4-circuit modular expansion, and a maximum medium temperature of 110 degrees C enabling dual sanitary and heating use. The product is positioned against traditional plumbing methods with claimed installation time reductions of 30-40% and fewer leak-prone fittings. Complementary accessories include the HERZ PIPEFIX adapter system. Production is conducted in the company's own factories with in-house quality control.

HERZ d.o.o. generates revenue through hardware sales of sanitary armature, valves, and plumbing products via the Herz Group distribution network and through direct distribution of the UNITAS and KOVINA branded lines. Primary customers are plumbing and HVAC installers, with secondary use cases among building occupants and property managers. In 2023-2024, the company executed the DIGIT HERZ digital transformation project, securing up to 1,834,324 EUR in EU NextGenerationEU co-financing via a five-party consortium (KOPIT, SMART CARGO, ART REBEL 9, EMPERIA) under Slovenia's Ministry of Economic Development and Technology JR Digit NOO public call, with the project delivered on 31 March 2024. Pricing information is not publicly disclosed.

Direct peers

• TECE: German manufacturer of installation systems including sanitary manifolds, flush technology, and pipework — a like-for-like European peer to HERZ's sanitary distribution portfolio.
• Caleffi: Italian manufacturer of hydronic components including water distribution manifolds, balancing valves, and connection fittings — a direct peer to HERZ d.o.o.'s sanitary water manifold and PIPEFIX product family.
• Uponor: Nordic manufacturer of plumbing and indoor climate solutions including manifold-based water distribution systems; comparable product platform and installer customer base to HERZ d.o.o.
• Viega: German family-owned manufacturer of plumbing press-fit systems, fittings, and manifold technology; closest direct competitor on installation-time-saving fittings innovation in the DACH region where HERZ has strong presence.
• Reliance Worldwide Corporation: Global plumbing fittings manufacturer (SharkBite, John Guest, HoldRite) with strong presence in push-fit and manifold distribution products; competes directly on speed-of-installation value proposition.
• Giacomini: Italian producer of heating and plumbing valves, manifolds, and distribution components; competes head-on with HERZ's UNITAS/KOVINA valve and manifold lines across European installer channels.

Broad incumbents

• Watts Water Technologies: US-listed global manufacturer of water safety and flow-control products including plumbing manifolds and valves; a much larger incumbent with overlapping product categories and European installer channels.
• Danfoss: Global heating and plumbing major with a broad portfolio of valves, manifolds, and district-energy components; competes with HERZ particularly in the dual sanitary/heating use case enabled by the 110°C rating.
• IMI Hydronic Engineering: Division of IMI plc offering hydronic balancing valves, control valves, and distribution components; broader global footprint and more extensive SKU set than HERZ d.o.o. but overlapping installer end-market.

Regional players

• Herz Armaturen: Austrian sister entity within the Herz International Group specializing in regulation technology; operates in the same corporate network as HERZ d.o.o. but focuses on thermostatic and regulation valves rather than sanitary manifolds — closest 'family' comparator.
