What Ortner does

Ortner GmbH is an Austrian manufacturer of ceramic storage ovens (Speicheröfen), wood-fired ovens (Holzbacköfen), and complementary refractory and mortar/plaster building products, headquartered in Loosdorf, Lower Austria. Founded in 1983 and operating as a subsidiary of Schmid Industrie Holding (SIH) since 2008 under Managing Director Dipl.-Ing. Manfred Huber, the company specializes in custom-built heating installations centered on its proprietary ORTNER Inside fireplace insert and KMS (Keramik-Modul-Speichersystem) high-performance ceramic storage modules, with the KAM top-mount storage, ORTNER Grundofenstein (GOS) insert, HTpro fire door, ABS combustion control app, and the VestaTherm storage-oven-plus-heat-pump sub-brand extending the product surface. Each installation is engineered to release stored radiant heat gradually over up to 24 hours from a single wood load, with the low-height N-Serie, N-H cooking variant, GO14/ST14 models, and the OSSO system-storage oven broadening the lineup for compact modern homes and whole-house heating.

Revenue is generated primarily through one-time hardware sales of storage-oven inserts, modules, fire doors, and refractory accessories, plus a smaller aftermarket stream of replacement parts and consumables. Distribution is exclusively indirect: customers are routed via an on-site Hafner search tool to certified Hafner (tile stove builder / heating engineer) partners who plan, customize, quote, and install each unit, supported by ORTNER-provided planning services, CAD libraries, and Hafner-Login tooling. End customers are individual residential homeowners seeking sustainable, blackout-resilient heating alternatives to gas; secondary segments include low-energy/passive-house builds (where time-delayed heat release prevents overheating) and energy-conscious consumers seeking independence from centralized fossil-fuel networks. Pricing is opaque and quoted per project by the installer; more than half of revenue is generated through exports, principally across the DACH region, supported by external sales representation in markets such as southwest Germany. The company has received multiple Austrian and Lower-Austrian innovation awards and was the first tile-oven-insert manufacturer to obtain the Austrian Eco-Label, and in 2023 began expanding its Loosdorf manufacturing facility to increase production capacity.
