Thermowatt

What Thermowatt does

Thermowatt S.p.A. is an Italian privately held manufacturer, founded in the early 1950s and headquartered in Arcevia (Marche), that designs and produces tubular heating elements and mechatronic thermostats primarily for residential and commercial electric water heaters, heat pumps, and household appliances. The company operates two manufacturing facilities — the original Arcevia plant and the Thermowatt Professional plant in Follina (Treviso), inaugurated in July 2023 after the acquisition and rebrand of DhE S.r.l. — and reports annual production exceeding 40 million pieces serving more than 500 customers in over 100 countries.

The product portfolio spans commodity tubular heating elements alongside increasingly connected and certified higher-value variants. The TMEC platform, now in its third generation as TMEC3E Wi-Fi (March 2026), integrates self-learning ECO algorithms, dual-band Wi-Fi 6, OTA updates, and Consumer-Led Flexibility/Demand-Side Response (CLF/DSR) support for grid programs; the SOLTMEC Wi-Fi Immersion Heater (June 2024) extends the platform into solar thermosyphon systems; and the Thermowatt Professional division markets ATEX-certified explosion-proof flanged heaters, direct-contact heaters, and 3MWatt duct heaters for industrial decarbonization and electrification projects. Certifications including ACCREDIA (lab accreditation extended to 2027), UL (US/Canada), ENEC-VDE (Europe), ATEX (explosive atmospheres), and SASO (Saudi Arabia) are actively maintained.

Thermowatt's revenue model is hardware sales through a global distributor and OEM channel, with no disclosed pricing or recurring-software monetization; a companion MyThermowatt APP enables remote monitoring and consumptions tracking for the connected product line. Go-to-market is event-driven and channel-led, anchored by recurring presence at ISH (Frankfurt), MCE (Milan), InstallerSHOW (UK), The BIG 5 (Dubai), SAUDI BUILD, HOST Milano, and Aquatherm Moscow. Ownership is private with €7.7M share capital and no disclosed parent, venture, or private-equity backing; leadership is led by CEO Marco Conti.
