ETA Heiztechnik

What ETA Heiztechnik does

ETA Heiztechnik GmbH is an Austrian manufacturer of biomass heating systems, founded in December 1998 and headquartered in Hofkirchen an der Trattnach, Upper Austria, with a second plant in Meggenhofen. The company designs and builds a full product portfolio of pellet boilers (ePE, ePE-BW, ePE-K, PU PelletsUnit, PC PelletsCompact), log boilers (eSH, optionally combined with the eTWIN pellet module), and wood chip boilers (eHACK in 20-240 kW and HACK VR in 250-500 kW), spanning 7 kW to 500 kW with cascade configurations up to 8 MW for district heating. Hardware is unified by the proprietary ETAtouch touchscreen control and the meinETA free cloud platform for remote monitoring via smartphone, tablet, or PC, and is wrapped with a modular component ecosystem — stratified buffer storage, fresh-water modules, stratified-charging modules, mixing-circuit modules, and heat-transfer stations — that enables system configuration from single-family homes through to village-scale heating networks. Cloud connectivity integrates with KNX, Loxone, and ModbusTCP, and EEP electrostatic particle separators support compliance with German dust-emission limits.

ETA operates a sales-led and event-driven go-to-market: products are sold almost exclusively through a network of certified installer partners, supported by an in-house field service organisation (~40 technicians in Germany plus coverage in Austria) and direct technical sales for larger district-heating, agricultural, and commercial projects. Revenue is generated from hardware sales, a spare-parts operation (operated via dedicated portal), paid commissioning and maintenance services (with weekend/holiday surcharges), and paid installer training programmes and factory tours (Holzfeuertage). Pricing is quote-based and not publicly disclosed; the company actively markets government subsidies (up to €8,500 in Austria under Sanierungsoffensive 2026 and up to 70% in Germany) to reduce net purchase cost.

ETA employs approximately 450 staff, produces up to 35,000 boilers per year, and exports roughly 85% of output to more than 25 countries including Japan, New Zealand, and most of the EU plus the UK. The company is privately held and led by managing directors Florian Minihuber and Ferdinand Tischler, with no parent or external investor disclosed in the source material. It carries the Austrian Ecolabel, MCS (UK), EFK Gold sustainability certification, INEO-Gütesiegel apprenticeship recognition, Interzero recycling certification, and PEFC premium-partner status, and is announcing an R&D centre expansion at its Hofkirchen headquarters in 2026.

Revenue model

1. Biomass Boiler Sales: ETA generates the majority of its revenue from the manufacture and sale of biomass heating systems — pellet boilers (ePE, ePE-BW, ePE-K, PU PelletsUnit, PC PelletsCompact), log boilers (eSH, SH), and wood chip boilers (eHACK, HACK VR) — in power ranges from 7 kW to 500 kW. Sales are channelled through installer partners and direct technical sales. Pricing is quote-based and not publicly disclosed.
2. Spare Parts & Replacement Components: ETA operates a spare parts division supplying replacement components (e.g., heat exchangers, sensors, control units, fan assemblies) to installers and end customers. Orders can be placed via a dedicated spare parts portal (spareparts.eta.co.at) or by contacting the spare parts team directly.
3. Service, Maintenance & Commissioning: ETA provides customer service including commissioning, on-site maintenance, and emergency support (including weekends and public holidays). Service is delivered through in-house field service teams and regional area representatives across Austria and Germany. Service calls on Sundays and public holidays are billed with a 100% surcharge.
4. Training & Factory Tours: ETA offers paid training courses for installers and technical staff, as well as paid factory tours (Holzfeuertage) at its Hofkirchen headquarters. Training covers boiler installation, technical operation, and maintenance procedures.

All systems are unified by the proprietary ETAtouch touchscreen control and the meinETA cloud platform for remote monitoring and control. Products are sold through a network of certified installation partners in Austria, Germany, and 25+ export markets and are supported by ETA's own field service team.

Product overview

ETA Heiztechnik is a specialist manufacturer of biomass heating systems, offering a comprehensive portfolio centered on three core product lines: pellet boilers (ePE, PU PelletsUnit, PC PelletsCompact), log boilers (eSH with optional eTWIN hybrid), and wood chip boilers (eHACK and HACK VR). The products range from small residential units (7-15 kW) to large commercial and district heating systems (up to 500 kW). The ecosystem is unified by the ETAtouch touchscreen control system and meinETA smart heating platform, with modular components including buffer storage tanks, fresh water modules, charging modules, and heat transfer stations that integrate to form complete heating solutions. The company targets single-family homes, multi-family buildings, commercial properties, agricultural operations, and district heating networks across Austria, Germany, and international markets.
