Helen
Summary
Helen is building a heat production complex in the Patola area in Helsinki, including two 50 MW electric boilers and an industrial-scale air-to-water heat pump.
The full district heating production capacity of the air-to-water heat pump, which uses outdoor air as its heat source, varies between 20 and 33 MW, depending on the air temperature. The refrigerant in the closed loop of the heat pump is carbon dioxide.
"The air-to-water heat pump plant to be built will be the first of its size in the world, and one of its significant advantages is that it can be operated in outdoor temperatures as low as -20°C. When completed, the heating plant complex will significantly reduce the CO2emissions caused by heating in Helsinki and bring us closer to the carbon neutrality goal. In addition, the plant is likely to create price stability for customers, as its production is easily adjustable," says Juhani Aaltonen, VP, Green Investments at Helen.
