What Roots Energy does
Roots Energy GmbH is a Vienna-based industrial infrastructure company founded in 2021 to decarbonize urban heating through a standardized modular district heating (Nahwärme) platform. The system combines industrially manufactured hydraulic products — most notably the proprietary Roots·Hub prefabricated hydraulic and control module, Soletherme brine-thermal units, and air-source absorbers — with integrated measurement, control, and instrumentation technology. Roots positions its offering between full-scale district heating and single-building air-source heat pumps, targeting the 52 million European homes still dependent on imported oil and gas where the heat transition has stalled. Operations are anchored by the €5M+ Roots·House R&D centre in Vienna-Penzing, which functions as a living lab for full urban heat scenario validation.
The company sells a combination of feasibility studies, design and planning services, consulting, hardware modules (Roots·Hub and related system components), digital monitoring and control services, and ongoing operational optimization. Pricing is project-based, with binding offers prepared on a per-project basis under multi-year contractual arrangements. Roots operates a sales-led go-to-market targeting two primary segments: property owners (Bestand, Neubau, Quartier) and energy contractors (Energie-Contractor), with planners and architects as a secondary persona. Distribution is direct via website enquiry, phone, and email, with the geographic footprint expanding from Vienna across the DACH region (Germany, Switzerland, Liechtenstein). Roots is privately held, founder-controlled, and has been capitalised to date through Austrian public research grants from FFG, the Vienna Business Agency, and the Climate and Energy Fund rather than disclosed venture capital. As of 2026, series production of core components from Austrian manufacturing has commenced with over 20 further DACH sites in implementation.

Roots Energy product offering
Product offeringCore offering
Roots Energy develops, manufactures and delivers a standardized modular district heating (Nahwärme) platform consisting of industrially prefabricated hydraulic products with integrated measurement, control and regulation (MSR) technology. The system combines geothermal (brine/ground-source) and air-source heat absorption with heat pumps to provide heating and cooling for urban districts, building groups and individual buildings, replacing central heating systems and decentralized gas boilers. Core product is the proprietary Roots·Hub, supported by Soletherme brine-thermal units and air-source absorbers. The company also provides feasibility studies, planning and engineering services, consulting for decarbonization, and digital monitoring/operational optimization services.
Product overview
Roots Energy is an industrial infrastructure company for urban heat, offering a standardized near-distance heating (Nahwärme) platform. The system consists of industrially manufactured hydraulic products with integrated measurement, control and regulation technology. The core products include the Roots·Hub (prefabricated hydraulic and control module), Soletherme (brine-thermal units with MSR), and Air-Source Absorbers. These modular components are designed for modularization, standardization, and series production, enabling deployment from single buildings to entire districts. The company also operates the Roots·House, their in-house R&D center and living lab for product development and testing.
