Aira has announced a €63 million investment from its current investors, including Temasek, Statkraft Ventures, Kinnevik, and Altor. This funding extends the €145 million Series B round concluded in January 2024, co-led by Temasek, Kinnevik, and Altor.
This financial boost will accelerate the electrification of residential heating across Europe, helping households lower energy costs, promote decarbonization, and reduce dependency on fossil fuels. With 130 million fossil fuel-based boilers still in use, residential heating is a significant carbon emitter, contributing 10% to Europe's total CO₂ emissions.
Aira specializes in smart heat pumps offered through affordable monthly plans, paired with clean energy tariffs and solar solutions. The new funds will support further expansion in Germany, Italy, and the UK, growing both market reach and a skilled green workforce. Additionally, Aira will enhance its clean energy-tech offerings to provide more savings to customers.
Since January's funding round, Aira has emerged as a leader in the clean energy-tech sector, launching its Aira Heat Pump and establishing a vast 220,000 sqm manufacturing facility in Poland. The company has also opened 11 regional hubs and is actively engaging with consumers, employing 1,200 people and achieving a €100 million annual revenue run rate.
The total €243 million equity funding underpins Aira's long-term growth strategy. Martin Lewerth, CEO of Aira Group, highlights the importance of this investment in expanding their integrated platform and market presence, emphasizing the need for cleaner heating solutions amid the ongoing cost-of-living crisis.
