Finland has recently taken a big step towards sustainable energy by installing the world’s largest Air-to-Water Heat Pump. This impressive project, located in the city of Espoo, aims to provide eco-friendly heating for thousands of homes. The new heat pump can produce 90 megawatts of thermal energy, making it the biggest installation of its kind in the world. The system extracts heat from the seawater of the Gulf of Finland and transfers it to the district heating network, serving homes and businesses in the area.

How the Air-to-Water Heat Pump Works
The Air-to-Water Heat Pump in Espoo uses seawater from the Gulf of Finland as a natural heat source. The pump captures the heat from the seawater and transfers it into the city’s district heating network. This process is efficient and sustainable, providing enough heat to warm up to 25,000 households. By utilizing seawater, the project reduces the city’s carbon emissions and aligns with Finland’s goals to phase out coal and natural gas for heating by 2025. This innovative system shows Finland’s commitment to clean energy and can serve as a model for other cities worldwide.
MAN Energy Solutions’ Role in Helsinki
The Finnish energy company Helen Oy has also partnered with MAN Energy Solutions to develop another giant Air-to-Water Heat Pump for the Patola heating plant in Helsinki. This heat pump will be able to produce between 20 to 33 megawatts of heat, depending on outdoor temperatures, and will still function efficiently even in very cold conditions as low as -20°C. The installation is part of Helsinki’s strategy to move towards carbon neutrality by 2030.
Environmental Impact and Sustainability
This Air-to-Water Heat Pump is expected to reduce CO₂ emissions by about 56,000 tons per year, equivalent to supplying approximately 200 gigawatt-hours (GWh) of heat to around 30,000 households. It will use CO₂ as a natural refrigerant and be powered by electricity from renewable sources like wind and solar energy. This approach not only supports the environment but also provides price stability for customers.
Advanced Technology for Efficiency
The heat pump at the Patola plant will feature a hermetically-sealed HOFIM® motor-compressor. This advanced design operates without oil, making the pump more efficient and reliable. The plant is expected to start production during the 2026-2027 heating season, representing a significant step in Helsinki’s shift towards sustainable energy.
A Model for Other Cities
Finland’s innovative use of Air-to-Water Heat Pumps demonstrates how cities worldwide can adopt sustainable heating solutions. The largest heat pump in Espoo, and the upcoming installation in Helsinki, highlight how countries can reduce their reliance on fossil fuels, lower carbon emissions, and achieve their climate goals. The success of these projects will inspire other cities to consider similar technologies, especially as they face growing challenges from climate change and energy needs.
The Future of Sustainable Heating
The Air-to-Water Heat Pump is not only a technological achievement but also an important step toward a sustainable future. As more cities look to replace outdated energy systems with cleaner alternatives, Finland’s example offers a clear path forward. By using natural resources like seawater and renewable energy sources, cities can reduce their environmental impact and provide reliable, affordable heating to their residents.
The Air-to-Water Heat Pump project is an excellent example of how countries can innovate to meet their energy needs sustainably. It shows that large-scale projects can be both eco-friendly and efficient, proving that sustainable energy is not only possible but also practical and beneficial for both the environment and the economy.
By investing in projects like these, cities can lead the way in the global fight against climate change, demonstrating that the future of energy is green, clean, and within reach.
