What te-sa does

TE-SA S.R.L. is an Italian manufacturer of hydro-thermo-sanitary components headquartered in Borgomanero (province of Novara), founded in 1986 by the Zerlia family (Renato, Sandra, Paola, and Mauro Zerlia) and remaining family-owned and operated across two generations. The company produces a vertically integrated portfolio of heating, cooling, and potable-water distribution components, including brass and stainless-steel distribution manifolds, regulating units for central heating systems, thermostatic and manual valves, lockshields, compression and press fittings, magnetic dirt separators, pressure reducers, and underfloor radiant heating and cooling systems sold under the Thermosystem sub-brand. More recent product development (Articles 762 hydraulic separator and 763 buffer tank, launched March 2024) is targeted at enabling efficient integration with heat pumps. The portfolio is organised around six "system solutions" (floor heating/cooling, central heating distribution, drinking water distribution, radiator heating, press fittings, and snow/ice melting) supported by approximately 18 core component categories.

The company's technology is rooted in mechanical, materials, and certification engineering rather than software or AI. Products are validated against a broad international certification stack covering ISO 9001:2015 (quality), ISO 14001:2015 (environmental), and ISO 45001:2023 (occupational health and safety) via ICIM, plus product-level DVGW, EAC (covering valves, manifolds, mixing units, pressure reducers, and zone valves for Eurasian markets), VUPS, and IIP certifications, which collectively enable cross-border distribution and act as a competitive barrier. Manufacturing, R&D, and administration are co-located at the Borgomanero facility; an SAP implementation in 2019 supports integrated company management. The firm claims market "leader" status in the Italian hydro-thermo-sanitary sector and has actively participated in international trade since 1998.

TE-SA operates a B2B, sales-led model targeting professional installers (plumbers, HVAC contractors) and the building and construction industry (construction companies and developers). Revenue is generated via hardware sales of components and integrated systems, with no public pricing — quotes are obtained via catalog requests and direct contact with the Italian Trade Department (domestic) or Foreign Trade Department (international, contact channel [email protected]). Go-to-market combines a multilingual website (Italian, English, French, Spanish, Portuguese, German, Russian), social channels (Facebook, Instagram, LinkedIn, YouTube), trade show participation such as Mostra Convegno Expocomfort in Milan, technical training and webinars for professionals, and newsletter outreach. The company markets itself on completeness of certified range, 40 years of manufacturing heritage, and ESG positioning (Synesgy 'A' rating, 2026). TE-SA is a private Italian S.R.L. with no external funding rounds, no parent company, and no subsidiaries; share capital is stated at €93,600.

Core offering

TE-SA manufactures and sells hydro-thermo-sanitary components for residential and commercial buildings, including floor heating and cooling systems, distribution manifolds (brass and stainless steel), radiator valves and lockshields, press and compression fittings, hydraulic separators and buffer tanks, magnetic dirt separators, and pressure reducers. The product range covers heating, cooling, and potable water distribution, with certified solutions for heat pump integration. Customers are professional installers, HVAC contractors, plumbers, and distributors served through dedicated Italian and Foreign Trade departments.

Product overview

TE-SA is a manufacturer of hydro-thermo-sanitary components established in 1986, offering a comprehensive portfolio of products organized into two main categories: system solutions and core product components. The system solutions include Floor Heating and Cooling Systems, Distribution Systems for Central Heating, Drinking Water Distribution Systems, Radiator Heating Systems, Press Fitting Systems, and Snow and Ice Melting Systems. The core product portfolio comprises Regulating Units and Central Heating Systems, Brass Chrome Distribution Manifolds, Stainless Steel Distribution Manifolds, Pre-Assembled Regulating Units, Accessories and Components for Manifolds, Thermosystem Radiant Floors, Manifolds for Drinking Water Distribution, Valves and Lockshields, Compression Fittings, Press Fittings, Hydraulic Separators and Buffer Tanks, Magnetic Dirt Separators and Filters, and Pressure Reducers. The products work together as integrated solutions - for example, the regulating units and manifolds form the heart of heating distribution, while valves provide control throughout the system, and accessories support installation and metering. The company emphasizes high manufacture quality, eco-sustainable products, and energy efficiency, particularly supporting heat pump installations with their hydraulic separator and buffer tank products.
