District heating

District heating is efficient, environment-friendly, and the best method for supplying thermal energy to densely populated areas.

District heating distributes the thermal energy generated by efficient central boiler plants or combined heat and power stations to heat substations via the heat network. Centralised thermal energy generation enables to implement the best possible technology, to select the types of fuel flexibly, and to enjoy the advantages of combined heat and power generation.

District heating is the most common type of heating in Estonia, with the share of district heating in the Estonian thermal energy supply amounting to at least 60 percent. It is a convenient type of heating from the consumer’s perspective which ensures security of supply and is environment-friendly.

All network areas of Utilitas qualify as efficient district heating areas for the purposes of the Energy Efficiency Directive (2012/27/EU) and use renewable fuels when operating at the base load.

Sisu Moodul

Heating is controlled by a heat substation installed in the building. The thermal energy reaches the building from the district heating undertaking and the consumer is not required to take care of anything heating-related, unlike in the case of several other types of heating (such as buying fuel).

District heating ensures a stable security of supply by using different boiler plants and a multifunctional thermal energy network.

District heating undertakings have boiler plants of various production options which use several types of fuels for heat generation. This enables to keep the price of thermal energy flexible and stable more easily than in the case of using just one type of fuel.


We use more and more environment-friendly and efficient technology to generate heat. This means that the damaging impact on the environment decreases and the technical development also enables to extract increasing amounts of thermal energy from the same amount of fuel. District heating keeps the air in the cities cleaner, as the high chimneys of the boiler plants, which meet environmental requirements, disperse the emissions better.
