Internationally Award-Winning AmbiHeat Plant Has Been Commissioned in Joensuu
The internationally recognized AmbiHeat plant, built next to Savon Voima’s Joensuu power plant, was commissioned in December. The facility received the prestigious Heat Pump City of the Year award in autumn 2025.
Electrified Heat Production Is Rapidly Gaining Ground – Flexible Solutions Respond to Market Changes
The structural transformation underway in Northern Europe’s energy sector is accelerating the shift toward electrified heat production. The rapid growth of wind power has brought large amounts of affordable and variable electricity to the market, making market-driven heat production more profitable than before.
MinersLoop Doubles the District Heat Production at Data Center with AmbiHeat® System Expansion
MinersLoop, a Finnish company operating in IT and energy sectors, is expanding the AmbiHeat® heat pump system by Calefa with an additional 2 MW of cooling capacity. The system, located next to the company’s data center and commissioned in summer 2024, will be increased by 2.5 MW in heating output — doubling the site’s district heating production.
KSS Energia Strengthens Its Electric Heat Production Profile with AmbiHeat Heat Pump Plant
Finnish energy provider KSS Energia and Calefa have agreed on the turnkey delivery of a 4 MW AmbiHeat heat pump plant. Utilizing excess heat from wastewater, the AmbiHeat facility will reduce CO2 emissions of heat production by 14,000 tons per year while also increasing the company’s capacity on the electricity markets.
The Artic Circle Celebrates World Water Day with a 40 GWh Heat Pump Plant
A new AmbiHeat plant by Calefa has entered the construction phase at Neve Oy’s wastewater treatment plant in Rovaniemi, Finland.
Finnish Company Leads the Way in Utilizing Data Center Waste Heat for District Heating
The energy system balancing data center of MinersLoop utilizes waste heat with a COP value of up to 5.

Heat pump plants increase much-needed energy self-sufficiency and bring cost benefits
Energy and cost efficiency, sustainability and energy self-sufficiency are drivers for better solutions in energy production. Energy self-sufficiency brings energy costs down. CEO of Calefa, Petri Vuori at the heat pump plant of Orion pharmaceutical factory in Turku, Finland. – In the current global situation energy self-sufficiency has become the number one priority. Energy production […]
A heat pump plant turns the carbon footprint of textile fibre production negative
The carbon footprint of the SPINNOVA® textile fibre is already 72% lower than that of conventionally produced cotton. With the AmbiHeat® heat pump plant and an energy ecosystem, each produced kilogram of textile fibre reduces overall CO2 emissions.
Kiilto and Lempäälän Lämpö start an energy ecosystem – remarkable reduction of emissions
When there is surplus, it could be of use to someone else. Sharing economy of an industrial manufacturer and the local energy company reduces emissions and improves energy efficiency. The end result is carbon-neutral district heating and zero-emission heating for the Kiilto chemical factory in Lempäälä, Finland.
