EVO

What EVO does

EVO Deutschland GmbH, headquartered in Mietingen, Baden-Württemberg, is a German manufacturer of electric storage heaters and integrated residential energy systems founded around 1970. The company designs and produces four electric heater product lines (Trend, Classic, Style, Individual) built around its proprietary EVOLIT storage core, which stores electricity in minutes and releases heat for approximately an hour, enabling efficient, maintenance-free operation. EVO extends this heating core into a holistic residential energy platform combining photovoltaic systems, battery storage, the TEHA-4 WP heat pump with PVT (photovoltaic-thermal) modules, and programmable thermostats (wired, wireless, or app-connected). All manufacturing is performed in Germany and backed by a 30-year product warranty.

EVO monetizes primarily through one-time hardware sales of heaters, PV arrays, energy storage, and heat pump systems, augmented by professional services including on-site heat demand calculation per DIN standards, in-house installation by 10+ mounting teams, financing arrangements, and certified TRGS 519 disposal of legacy night storage heaters. The go-to-market is consultative and direct-to-consumer: 70+ field consultants (Fachberater) conduct home visits across Germany, supported by a toll-free service hotline (0800 250 50 50), a website with catalog ordering, and trade fair participation. Primary customer segments are German homeowners in new construction, renovation/modernization, holiday properties, auxiliary spaces, and night storage heater replacement, with secondary exposure to hospitality and municipal infrastructure projects. The company has expanded internationally through Chinese CCC certification, stated operations in 7+ European markets, and two completed acquisitions: Sonne-und-Strom (2016) and SOLARIS and more GmbH (March 2026).

Core offering

EVO designs, manufactures and sells electric storage heaters (Trend, Classic, Style, Individual lines built around its proprietary EVOLIT storage core), complemented by residential photovoltaic systems, battery energy storage and the TEHA-4 WP heat pump with PVT modules. The company offers a turnkey integrated energy ecosystem (PV + storage + electric heating) plus in-house installation and certified night storage heater disposal, primarily targeting German homeowners and small builders for new builds, renovations and heating retrofits.

Product overview

EVO offers a modular energy solution ecosystem centered on electric storage heating systems. The core product lineup consists of four electric heating (Elektroheizung) series—Trend, Classic, Style, and Individual—which form the primary heat delivery system. This core is complemented by integrated energy solutions: a complete set combining photovoltaic (PV) systems, energy storage batteries, and electric heating for near-zero-cost solar-powered heating; a heat pump system (TEHA-4 WP) with PVT hybrid modules; and smart thermostats for precision control. EVO positions these components as an integrated system where customers generate solar electricity, store it, and convert it to heat using EVO's electric heaters, achieving high energy independence. Additional services include heat demand calculations, installation, and night storage heater disposal. The company manufactures in Germany with a 30-year warranty on heating products.

Direct peers

• Stiebel Eltron: German manufacturer of electric heating systems, heat pumps, and domestic hot water solutions. Directly competes with EVO in the electric storage heater category and shares the German Mittelstand manufacturer profile, with similar focus on integrated renewable energy solutions.
• Dimplex (Glen Dimplex): European specialist in electric heating, heat pumps, and ventilation. Competes head-to-head with EVO in electric storage heaters and shares the renewable-electric-heating thesis, including complementary product lines for residential and light commercial applications.
• Elnur: European manufacturer of electric heating solutions including storage heaters and convection heaters. Comparable to EVO in product mix (electric heating at the core) and customer segment (residential retrofits and new builds), though with different geographic focus.

Broad incumbents

• Vaillant: One of Germany's largest heating manufacturers with a broad portfolio spanning gas, oil, heat pumps, and hybrid systems. Overlaps with EVO in heat pumps and increasingly in electric heating, but operates at significantly greater scale with broader installer networks.
• Viessmann: Major German heating, industrial, and refrigeration systems manufacturer with comprehensive heat pump, gas, and hybrid heating offerings. A key incumbent competitor in the residential heating transition with substantially larger R&D and distribution resources than EVO.
• Bosch Thermotechnik (Buderus): Bosch's heating division including the Buderus brand offers heat pumps, gas heating, and integrated energy solutions across Europe. Comparable to EVO in targeting residential heating retrofits and new builds, but with vastly greater scale, brand reach, and installer network.
• Wolf (Bosch): Heating systems manufacturer (part of Bosch) offering gas, oil, heat pumps, and solar thermal solutions. Competes with EVO across multiple product categories in the residential heating transition, with a broader portfolio but less specialization in pure electric storage heaters.
• Daikin: Global HVAC leader with a strong heat pump portfolio in Europe. Increasingly overlaps with EVO's heat pump offering (TEHA-4 WP) and brings significant R&D, scale, and installer relationships, though Daikin's residential heat pump focus is air-source rather than EVO's PVT-integrated approach.
• Junkers Bosch: Bosch-owned residential heating brand offering gas condensing boilers, heat pumps, and solar thermal systems. Competes with EVO in residential heating modernization, particularly in renovation and energy-efficiency upgrade use cases.

Emerging players

• Sonnen (sonnen GmbH): German residential energy storage specialist (Shell-owned). Overlaps with EVO's energy storage component of the Komplettset and shares the German residential energy transition thesis, though focused purely on storage rather than integrated heating.
