Get to know district heating – a care-free, smart choice

When you select district heating as your heating method, you will ensure peace of mind and join our crowd of satisfied customers.

District heating, which has a competitive price and is environmentally sound, promotes the life of current and future generations. District heating makes living more comfortable and always keeps Finnish population centre residents warm.

Almost every second Finn lives in a district heated house which means that district heating is the most common form of heating in Finland. About 90% of residential blocks of flats, about 50% of row houses and the majority of public buildings in Finland have district heating.  


How district heating works and production 

District heating is produced locally and transferred from the power plant to customers via hot water running through district heating networks. The cooled district heating water is returned to the power plant for reheating. 



District heating is always locally generated utilising the fuel that is most appropriate for the location. Most of district heating generation is based on combined heat and electricity generation.

The co-generation of power and heat has a central role in the reduction of the environmental load and fulfilment of the objectives set for the reduction of greenhouse gas emissions. In the
co-generation, excess energy from power production is used for district heat production instead of conducting it as condensate heat to waterways, for example.

Co-generation is efficient, since it utilises almost 90 per cent of the energy contained in the fuel. Through co-generation, environmental emissions are 30% lower than in the case where electricity and heat are generated separately. Most of district heat generation, i.e. about 80%, is based on combined heat and electricity generation. District heat is also generated in separate heat plants. 

We want to be a forerunner in environmental matters


Sustainable energy production requires that renewable sources of energy are used more frequently. We continuously develop the use of biofuels in heat production and the goal is to design new plants so that biofuels can be used in them. Our goal is to use renewable biofuels more extensively in heat production.
