What Schellinger does

Schellinger KG is a sixth-generation family-owned German limited partnership headquartered in Weingarten, Baden-W\u00fcrttemberg, that produces and distributes ENplus-certified premium wood pellets (Sonnen-Pellets) and manufactures a proprietary line of pellet storage and extraction hardware under the Maulwurf brand. The company controls the full value chain from regional sawmill by-product sourcing through pellet production at its Krauchenwies facility (operated by sister company Sonnen-Pellets Krauchenwies GmbH & Co. KG), logistics, and direct tank-truck delivery to end customers. Stated production capacity is 150,000 tonnes per year, and Schellinger claims up to a 6x lower CO2 footprint than conventional German pellets due to regional sourcing and short delivery routes.

The Maulwurf product family comprises the Maulwurf Classic, E2, and E3 extraction devices plus the turnkey Maulwurftank, all built around a patented top-down extraction principle that prevents pellet segregation and maximizes usable storage volume. The Sonavis ultrasonic fill-level measurement system and its companion Online Portal add a digital inventory and consumption-monitoring layer to the hardware base. Revenue is generated through per-tonne pellet sales (transactional, with delivery), hardware sales of storage technology, integrated logistics services, and a smaller W\u00e4rme-Contracting (heat contracting) offering. The company serves residential homeowners (single and two-family homes, including oil-to-pellet conversions), commercial and municipal institutions (churches, housing complexes, municipal buildings with installations up to 160 kW), and the trade channel of planners, installers, and energy consultants. Geographic focus is the DACH region with extension into France and Poland, distributed primarily via direct e-commerce, tank-truck delivery, trade shows (GETEC, IFH/Intherm, WEBUILD Energiesparmesse), and factory open-day events (Holzpellet-Infotage) at the Krauchenwies production site.

Revenue model

1. Sonnen-Pellets (Wood Pellets) Sales: Production and sale of certified wood pellets (Sonnen-Pellets) to residential, commercial, and municipal customers. Pellets are sold by the tonne with delivery. Revenue is generated per transaction based on volume ordered. The company controls the full supply chain from raw material sourcing to delivery.
2. Pellet Storage Technology (Lagertechnik): Sale of proprietary pellet storage solutions including the Maulwurf product family (Classic, E2, E3), Maulwurftank, and Sonavis fill-level measurement systems. These products serve as complementary offerings to pellet sales, enabling complete pellet heating solutions.
3. Logistics and Delivery: Pellet delivery services via specialized tank trucks. Delivery is a core part of the customer experience, integrated into the pellet sales process.
4. Wärme-Contracting: Heat contracting services where the company supports monitoring and supply of pellet heating installations, reducing customer management burden and eliminating supply gaps.

Core offering

Schellinger produces and sells premium regional wood pellets under the Sonnen-Pellets® brand, certified to ENplus standards, delivered by specialized tank trucks to residential and commercial customers across the DACH region. The company also designs, manufactures, and sells the proprietary Maulwurf® family of pellet extraction and storage equipment (Maulwurf Classic, E2, E3, and the turnkey Maulwurftank) along with the Sonavis® ultrasonic fill-level measurement system, providing a fully integrated pellet heating solution from a single provider.

Product overview

Schellinger offers an integrated pellet heating and storage solution comprising Sonnen-Pellets® (premium wood pellets as the core heating fuel) and the Maulwurf® family of pellet storage technologies. The product portfolio includes the Maulwurftank (a complete turnkey storage tank system for up to 7.2 tonnes), the Maulwurf Classic/E2/E3 extraction devices (patented top-extraction technology that ensures complete pellet withdrawal and maximizes storage utilization), and Sonavis® (an ultrasonic fill-level monitoring system). The Maulwurf extraction systems form the central technology platform, while Sonavis® provides digital inventory management. Together, these products enable complete pellet heating solutions from a single provider for residential, commercial, and municipal applications.

Products and services

• Sonnen-Pellets® Premium ENplus-certified wood pellets for residential and commercial heating, made from 100% regional sawmill by-products sourced from sustainable forestry, with CO2-neutral combustion properties. Sold by the tonne with direct tank-truck delivery across Germany, Austria, Switzerland, and France.
• Maulwurftank Compact complete storage tank for annual pellet supplies up to 7.2 tonnes, featuring integrated Maulwurf Classic extraction technology. Designed for space-saving installation in single and two-family homes, with simple steel-frame assembly and compliance with DIN EN ISO 20023 and VDI guideline 3464.
• Maulwurf Classic Pellet extraction device using top-down extraction principle for gentle material handling and nearly complete pellet removal from storage, designed for storage options up to 8 tonnes. Prevents pellet segregation by moving across the pellet surface and creating a level extraction surface.
• Maulwurf E2 Smart extraction system for medium-sized pellet storage of 4 to 16 tonnes. Compact, flexibly deployable, and designed without sloped floors to maximize usable storage volume in residential and small-commercial installations.
• Maulwurf E3 Advanced extraction system for flexible geometries and large pellet storage installations. Features targeted movement across pellet piles to create a completely level pellet surface for uniform extraction, suited to high-capacity commercial and institutional heating installations.
• Sonavis® Füllstandsmessung (Fill-level Measurement System) Ultrasonic sensor-based fill-level monitoring system for pellet storage. Sensors measure the pellet surface, calculate reserve quantity, and transmit data to a fixed-installed base device or the Sonavis Online Portal, providing fill-level history, current fill level, storage capacity, average weekly consumption, and refillable pellet quantity independent of room geometry or storage size.
• Wärme-Contracting (Heat Contracting) Heat contracting service in which Schellinger supports monitoring and supply of pellet heating installations, reducing customer management burden and eliminating supply gaps for residential and commercial customers.

• Vaillant: Vaillant is a leading European heating technology manufacturer with broad offerings across gas, oil, heat pumps, and biomass systems plus heating distribution and storage components. Comparable as a broad incumbent in residential heating whose biomass and storage products target the same DACH customers as Schellinger.
• Bosch Thermotechnology: Bosch Thermotechnology is a major global heating and hot-water solutions provider with strong presence in DACH, including biomass and condensing heating systems plus service networks. Comparable as a broad incumbent whose scale, brand, and installer relationships could pressure Schellinger's premium regional positioning.
• BayWa: BayWa is a German conglomerate with significant renewable energy, agricultural, and building-materials operations, including wood pellet distribution and trading across Europe. Comparable as a broad incumbent with national-scale pellet sourcing and distribution that competes with Schellinger's regional Sonnen-Pellets positioning.
