About SA-Energietechnik
SA-Energietechnik GmbH, headquartered in Ennsdorf (Upper Austria), is a one-stop provider of renewable energy systems. The company develops and manufactures its own heat pump components and the patented SA Hydrotower system, which combines heating, cooling and energy storage in a footprint of around 1 m² and integrates the entire building services as a compact plant centre. The units are tested and further developed in cooperation with the FH Burgenland and carry the EHPA quality seal. The service portfolio includes heat pumps (air-water, brine-water, water-water, air-air), photovoltaic systems and PV carports with charging infrastructure (5–25 kWp), battery storage, Midea air conditioning systems, smart home systems, and installer work from heating load design through commissioning to nationwide maintenance and remote maintenance across Austria. Customers include private home owners, developers such as ELK Bau, GCA Wohnbau and IPB, as well as hotels and large enterprises.
