Harvia Acquires Italian Timer Switch Maker Phoenix El-Mec to Secure Supply Chain

Harvia Plc signed and closed an agreement in September 2023 to acquire 100% of Phoenix El-Mec srl, an electromechanical timer switch manufacturer based in Belluno, in the Italian Alps north of Venice. Deal terms were not disclosed. The acquisition, described by management as a tactical rather than strategic M&A, was framed by Harvia as an investment in supply chain resilience: Phoenix El-Mec, a long-time supplier, makes a key component in Harvia’s basic sauna heaters. (See all Harvia M&A activity in our Harvia News hub.)

What Phoenix El-Mec makes

Phoenix El-Mec produces electromechanical timer switches that are a key component in Harvia’s basic (entry-level) sauna heater lines. The timer switch is the analog knob-plus-timer that sets heater run time on older model sauna heaters (as distinct from digital control units like the Harvia Xenio or Harvia Fenix). The company also supplies timers to other industries including ovens, drying cabinets, and boiler manufacturers.

Phoenix had been Harvia’s timer switch supplier since its establishment in 2013, a ten-year commercial relationship. The acquisition, in effect, formalized that relationship into vertical integration.

Why it matters: supply chain control

Harvia described the acquisition at its Capital Markets Day 2024 as an example of a tactical M&A transaction, as opposed to the strategic M&A transactions like ThermaSol, EOS, and Almost Heaven. The framework matters for investors parsing Harvia’s M&A strategy: strategic acquisitions expand the product portfolio or geographic reach; tactical acquisitions secure or de-risk the existing supply chain. Both are part of the toolkit but should be sized and valued differently.

Harvia framed the deal as supply-chain resilience: owning the maker of a key component in its basic heaters would help ensure its availability. The acquisition also gave Harvia access to the supplier’s other customer relationships (ovens, boilers, drying cabinets), which can generate incremental non-sauna revenue at low marginal cost.

Integration and adds to European footprint

Phoenix El-Mec continues to operate from Belluno, adding Italy to Harvia’s production footprint alongside Finland (Muurame, Sastamala), Romania (Gheorgheni), and Germany (Driedorf, via EOS). The company is a small fraction of Harvia Group revenue and headcount but is critical path for a product category that still represents meaningful volume across Harvia’s entry-tier electric heater lines globally.

Correction, September 25, 2026: an earlier version of this article said the deal addressed a single-source supply problem that emerged from 2020 to 2023, that Phoenix El-Mec’s capacity and technical reliability had become a gating factor for Harvia’s basic heater availability, and that the acquisition solved that problem. Harvia’s release describes no supply problem: it described Phoenix El-Mec’s timer switches as reliable and high quality and said the acquisition would strengthen its supply chain and ensure the availability of the component, per Harvia’s release of 29 September 2023. Its summary also dated the announcement to 26 September 2023; the release is dated 29 September 2023.
