Heim AG heating systems

What Heim AG heating systems does

Heim AG is a privately held Swiss renewable-energy company, founded in 1989 and headquartered in Aadorf (Thurgau), operating across two divisions: Heim AG Heizsysteme (heating systems) and, since 2023, the spin-off Heim AG Solarsysteme (solar systems). The company designs, manufactures, and services heat pumps (air-water, brine-water, and industrial-scale systems including R290 natural-refrigerant models), wood-combustion boilers (proprietary HEIM-Energie series spanning 3.5 kW to 1500 kW), photovoltaic installations, battery storage, EV charging infrastructure, combined heat and power (CHP) units, and intelligent energy management. A core proprietary platform is the Heim Manager energy management system — a manufacturer-independent controller integrating more than 400 devices across 30+ partner brands (SMA, Huawei, KOSTAL, Fronius, Tesla, BYD, SolarEdge, Victron, KEBA, Stiebel Eltron, etc.) to optimize self-consumption of solar electricity across heating, hot water, EV charging, and storage loads.

The business model is primarily direct sales-led, combining hardware sales of in-house manufactured equipment with professional services spanning consulting, technical planning, custom production, installation, and lifetime operation & maintenance. Revenue is generated across a vertical-segmented customer base: single-family homes, multi-family buildings, agriculture and forestry, wood-processing operations, district and remote heating networks, and commercial/industrial facilities. Pricing is predominantly quote-based, with one publicly disclosed maintenance price point (CHF 320 for summer maintenance of heat pumps up to 25 kW). Distribution is exclusively domestic across six Swiss branch offices (Thurgau, St. Gallen, Graubünden ×2, Bern, Fribourg), served through direct field sales, a Fachpartner (specialist-partner) network, and digital lead generation via the company's bilingual German/French website and Google Ads.

The competitive position rests on Swiss-made custom manufacturing, 35+ years of category specialization, and the breadth of the Heim Manager integration ecosystem. Strategic emphasis is on full-lifecycle customer partnerships, cross-selling across heating and solar divisions, and regulatory alignment with F-Gas-driven natural-refrigerant adoption and Swiss decarbonization policy.

Broad incumbents

• Viessmann: German global manufacturer of heating, industrial and refrigeration systems including heat pumps and biomass boilers. Direct comparable in heat pump and biomass heating categories served by Heim AG, but operates at vastly larger global scale with broader product portfolio beyond renewable energy.
• NIBE Energy Systems: Swedish-listed manufacturer of heat pumps and heating solutions, one of Europe's largest heat pump suppliers. Directly comparable in residential and commercial heat pumps, with substantially larger R&D and manufacturing scale.
• Vaillant Group: German-owned heating, ventilation and air-conditioning manufacturer with brands including Vaillant and Saunier Duval. Directly comparable in residential heat pumps and biomass heating, with broader European footprint.
• Bosch Thermotechnology: Division of Bosch producing heating systems including heat pumps and biomass solutions. Comparable in product categories but operates as part of a much larger diversified industrial conglomerate with greater capital resources.
• Daikin Europe: Global HVAC leader with strong European heat pump portfolio (Daikin Altherma). Comparable in heat pump manufacturing and integration of heating with cooling, but at much larger scale with broader climate control portfolio.

Direct peers

• Stiebel Eltron: German manufacturer specializing in heat pumps, hot water technology, and ventilation. Closely comparable to Heim AG's heat pump business including air-water and brine-water systems, with overlapping target segments in residential and commercial heating.
