Stockholm-based Aira has raised €150 million in equity financing to scale operations, expand its clean energy-tech range, boost R&D in Sweden, increase production in Poland, grow market presence, and strengthen industry partnerships.
The investment is secured from existing investors, Altor, Kallskär, Kinnevik, Lingotto and Temasek. Aira is backed by other climate and innovation investors including the Burda family, Collaborative Fund, Creades, Nesta Impact Investments, and Statkraft Ventures.
“This investment reflects the strong, long-term support of our investors and enables us to build on the substantial foundation we’ve established as we transition from a start-up to scale-up,” said Peter Prem, Aira Group CEO. “It empowers us to double down on our mission to take Europe off gas by expanding with operational excellence, launching new innovations, and accelerating our growth to bring clean energy-tech to millions of homes.”
Since launching in 2023, Aira accelerates the electrification of residential heating with intelligent clean energy-tech to help consumers reduce increasingly volatile energy bills and enable the net zero transition.
Aira’s vertically integrated model, combined with a consumer-centric monthly payment plan that requires no upfront cost, aims to deliver best-in-class consumer economics.
Aira has expanded into Germany, Italy, and the UK, rapidly establishing itself as a leading clean energy-tech company in Europe, with a reported annual sales run-rate of €200 million.
Among its benefits, Aira offers a monthly payment plan, end-to-end service, and a 15-year Aira Guarantee. The company now employs 1,200 people and has opened 18 hubs and four Aira Academies to train heat pump installers across Europe.
The equity will drive the accelerated scale-up of Aira’s operations and the expansion of its intelligent clean energy-tech offering. Aira will invest in its Swedish R&D centre to develop its integrated product portfolio, while increasing production capacity at its factory in Wroclaw, Poland.
At the same time, Aira will deepen its presence in existing markets and strengthen strategic partnerships with key players in the home and energy sectors to boost market presence and deliver greater cost savings for customers.
With 130 million boilers still in use across Europe, Aira says residential heating is the third largest emitter of CO₂ across the continent, contributing to 10% of Europe’s total emissions. By switching from a gas boiler to an air source heat pump, Aira argues that customers can reduce their household heating costs by up to 40% and CO₂ emissions by up to 100% with clean energy tariffs.
“The European heat pump market is expected to reach more than €150 billion by 2030, and with our vertically integrated model and world-class products, Aira is uniquely positioned to transform home energy across Europe,” added Prem. “Backed by world-class investors, we’re building a clean energy-tech leader with expert teams and a clear mission to decarbonise residential heating, all while lowering energy bills and increasing household comfort for millions. We’re just getting started. Aira is ready to lead the clean energy transition – one home at a time.”
