Domotec

What Domotec does

Domotec AG is a privately held Swiss specialist in hot water production and sustainable heating, founded in 1976 and headquartered in Aarburg with branch offices in Puidoux (French-speaking Switzerland) and Mezzovico-Vira (Ticino). The company designs, assembles, and distributes water heaters, heat pumps (air/water HPSU 4–18 kW, brine/water Nautilus 7–100 kW, ultra-quiet SilentLine 8–55 kW), heat pump water heaters (NUOS family, including 300/400 L stainless steel models), and high-capacity commercial systems (Syncro delivering up to 50,000 liters of hot water per day, paired with the Aquadomus automated circulation and hygiene system). All heat pumps carry PAC System-Module certification, qualifying buyers for cantonal subsidies of 2,000–12,000 CHF, and products comply with SIA 385/1, SIA 385/2, and SVGW W3/C3 standards. Digital touchpoints include the Webcontrol IoT remote monitoring platform (with BACnet IP integration), the SyncroTool planning and visualization tool, and a 2023-launched e-commerce webshop.

The business model is hardware-led (product sales of water heaters, heat pumps, storage tanks, solar and chimney systems) complemented by recurring after-sales service and maintenance contracts, hygiene inspections, original BUMA spare parts (acquired from Buma Haustechnik AG in February 2021), and free technical training for installers. Go-to-market combines a 12+ strong network of regional field sales advisors covering every Swiss canton, physical showrooms in Aarburg and Puidoux, the e-commerce shop, and an annual trade show presence at Swissbau, Bauen & Modernisieren, Zuger Messe, Habitat-Jardin, and the GTW Forum. Customers are split between private end consumers (homeowners served via showrooms, website, webshop, and field advisors) and business customers (sanitary installers, heating engineers, planners, architects, plus project-based work for hotels, hospitals, sports facilities, and EMS operators such as Seelandheim), with more than 5,000 customers served annually across all of Switzerland.

Governance is led by CEO Silvio Di Pietro, who succeeded long-serving CEO Ueli Ehrbar in January 2021; the senior team includes a Sales Director, Head of Finance, HR Manager, Marketing & E-Commerce Manager, and a Puidoux branch manager. The company remains founder- or independently-owned with no external investors, no parent company, and no public listing. Strategically, Domotec emphasizes Swiss-made quality, regulatory certification, a multilingual nationwide service footprint, and incremental product and ecosystem expansion (NUOS 300 V6 in March 2025, Regusci Reco SA partnership in Ticino in October 2024, 50th-anniversary milestone in June 2026) rather than venture-scale growth.
