At 42watt, we pursue a clear mission: to make energy-efficient modernization simple, reliable, and efficient – and to find the right solution for every home.
To achieve this, we combine in-depth energy consulting with clear processes, digital tools, and a strong network of skilled trade partners. We take a holistic approach to heat pumps, solar energy, and insulation, guiding homeowners step by step – from analysis and planning to funding, implementation, and beyond.
Our ambition goes beyond individual projects: we aim to make energy-efficient homes the new standard. In a market that often promises “fast and cheap,” we stand for trust, reliability, and long-term efficiency.
42watt was founded in Munich in 2021. Our goal is to reduce the energy consumption of buildings to the point where a climate-neutral building sector becomes a reality by 2045.
