NuuEnergy Secures €4.3M To Expand Heat Pump Installations

The round was led by amberra, the corporate venturing studio of the Cooperative Financial Network Volksbanken Raiffeisenbanken, with participation from EnjoyVenture and existing investors HTGF, Vireo Ventures, better ventures, and Bynd Venture Capital.

The heat pump market has grown strongly in recent years, despite a slowdown in 2024. Around 229,000 units were sold last year, and annual installations could reach 500,000 by 2030, according to the German Heat Pump Association. Although heat pumps can significantly reduce building-related CO₂ emissions, expansion is limited by skilled labour shortages and inefficient installation processes.

Founded in late 2023, nuuEnergy seeks to tackle these challenges with a locally focused, digitally enabled installation model. The company generates revenue from system planning, installation, and long-term maintenance contracts, as well as additional services such as water treatment and energy consulting.

To build regional specialist “hubs,” nuuEnergy attracts skilled workers with modern software tools and structured working environments. Positioned between traditional craft businesses and fully digital installers, the company uses digitised processes and on-site system planners to deliver tailored technical solutions and improve installation efficiency.

Commenting on the funding, Tobias Klug, co-founder of nuuEnergy, said customers are looking for local partners that guide them through the full process, from planning to installation and service, adding that the new investors will support the development of the company through both capital and expertise. He also noted that cooperative banks can provide tailored financing options to support local heating transition projects.

Julia Rafschneider, co-founder of nuuEnergy, added that the approach strengthens the company’s regional, quality-focused strategy and supports its skilled workforce.

The newly secured funding will support the expansion of regional specialist hubs and accelerate the digitalisation of the installation process.
