District cooling is similar to district heating as the cooling is produced centrally, and the customer’s cooling substations are connected to the cooling network.

The water is cooled in the district cooling plant and directed through the pipeline to the cooling substation in the client’s building. There, it cools the ventilation air of the building and the water circulating in the cooling system. Once the coldness of the water is depleted or “given away” in the cooling process, it then returns to the district cooling plant where it is cooled again. In addition to ventilation, district cooling is also used in cooling beams and cooling cassettes.

District cooling can be used in business and commercial buildings, as well as in new or renovated apartment buildings. Utilitas offers district cooling services in Tallinn City Centre and Ülemiste area, and new clients are constantly being added to the rapidly developing district cooling network.

In order to join district cooling, you need to contact our experienced Utilitas specialists, who will assist you with the options to connect to the district cooling network.

A heating substation is a set of equipment that includes heat exchangers, regulating devices, pumps, measuring devices, valves, and other pipe fittings, and the necessary piping. With the help of the heating substation, the thermal energy from the district heating network is transferred to the consumer’s heating and domestic hot water network. This allows you to adjust the heating and domestic hot water temperatures as needed.

The most important parameters to monitor are the temperature of the heat carrier from the building’s heating substation to the return piping (T2) and the temperature difference between the supply and return flow (ΔT). T2 should be less than 45°C and ΔT not less than 25°C. ΔT must not be less than 3°C. If the measurement range established for the operation of the heat meter is not guaranteed, the heat seller has the right to create an invoice for the corresponding period on an estimated basis.

The operating parameters of the heating substation can be seen followed in the self-service portal and have hourly accuracy.

A pressure test is the testing of pipelines under increased pressure to detect leaks. Utilitas performs heating pipe pressure tests every year. A pressure test on the primary side of the customer’s heating substation must be performed with a frequency of once every two years with a pressure of 1.0 MPa. The customer is responsible for carrying out a pressure test on their heating substation.

In order to reconstruct the heating substation, you must request the technical conditions from Utilitas. These are the basis for the design and construction of the heating substation. The project must be approved by Utilitas. Before installing the heating substation, the passport of the heating substation must be submitted to Utilitas for approval (the dimensioning sheet for the substation’s equipment, the diagram of the heating substation, and the position plan).

The heat load of a building is the heat demand determined during the design of the building’s heating system, which ensures hot water in the building and the internal temperature of the rooms at an outside air temperature of -22°C.

The heating substation passport is a document that includes the technical data of the heating substation (the dimensioning sheet of the substation’s equipment, the diagram of the heating substation, and the position plan). The loads given in the heating substation passport are the basis for fixing the heat loads in the purchase-sale contract. The customer is responsible for presenting the heating substation passport. As a rule, the passport is drawn up by the manufacturer of the heating substation. You can also ask Utilitas for passports of older already installed heating substations. We can issue a copy if we have them.

Radiators are part of the building’s common heating system. If you want to replace radiators, it is necessary to contact the building manager in order to select radiators suitable for the building’s heating system. Unauthorized and uninformed changes to the system can damage the entire system.

A heat meter is a set of measuring instruments that measure the amount of heat consumed. The heat meter is installed by the heat seller, unless otherwise agreed.

Verification proves that the heat meter is in working order and that the required accuracy level of measurement is guaranteed. According to the Measurement Act, heat meters must be properly checked verified every five years. The owner of the meter is responsible for organizing the verification. As a rule, heat meters belong to Utilitas.

The remote reading system is a set of technical devices that enable the automatic collection and transmission of heat meter readings. The remote reading system is installed by Utilitas.

A filling water meter is a water meter that records the amount of heat carrier, i.e. filling water, used to fill the heating system, and lost during the process. Please forward the filling water meter readings to klienditugi@utilitas.ee at least once a year, or immediately after a major loss or use of water (for example, after filling the heating system).

Data on the consumption of the building and metering points are visible on an hourly accuracy via the e-service portal.

The estimated amount of heat consumption is calculated in case the heat meter is not in working order, but the consumption still took place. It is based on actual average consumption (and the outdoor air temperature).

Filling water is chemically treated water that carries heat through the district heating network from the boiler house to the consumer’s heating substation and is used to fill the consumer’s heating system. The amount of filling water consumed is measured with a filling water meter. A filling water cost occurs when there is a leak in the heating system or the building’s heating system is emptied, for example, to replace radiators. The cost of filling water in a well-maintained and properly working heating system is almost non-existent. Since the filling water is heated, in addition to the water, the heat that was used to heat the water is also calculated. The price of filling water is fixed by Utilitas in the price list.

A standing payment order for e-invoices can only be concluded through a bank. If you want the invoice to be sent directly to the bank, you can order it from your bank/e-invoice center or write your request to Utilitas, giving your bank account details.

Invoices can be found and downloaded in the e-service portal.

Invoices can be found in the e-service portal.

District heating is also used to heat your domestic water, and the heat energy used to heat the water is reflected on the invoice.

Utilitas sale prices are cost-based. Therefore, we can only calculate the sale price of the previous month when the invoices from the suppliers have been received. Confirmed prices are published on our website.

According to the District Heating Act, the maximum price of heat is confirmed by the Competition Authority. The selling price of heat can be equal to or lower than the maximum price. If the actual costs turn out to be lower than predicted, the heat company can sell heat for less than the maximum price.

The maximum price is designed in such a way that the company is guaranteed to cover their operational costs, investments to fulfill operating and development obligations, costs to meet environmental, quality and safety requirements, and justified profitability. Read more on the website of the Competition Authority.

The fuels used can be tracked by price zones. Previous years’ data are available in the e-service portal.

You can see the CO₂ footprint of the last full year of heat consumption for your building in our e-service portal.

Utilitas issues a heating invoice for the entire residential building. The owner/manager of the building deals with the invoices and the settlement between apartments. There is no uniform or mandatory methodology for distributing the building’s overall heating costs between apartments, a freely chosen methodology can be applied. Therefore, the apartment association’s accountant or the chairman of the board can share information about your invoice directly.

The calculation methodology for the amount of heat needed to heat domestic water is chosen by each building manager, and therefore water heating prices may differ from building to building.

One possible calculation method is to use the following formula: water heating cost = consumed m³ x season coefficient x heat price. The seasonal coefficient is the calculated amount of heat required to heat one cubic meter of cold water to 55 degrees Celsius. From October to April, the estimated amount of such heat is 0.06 MWh, and from May to September, it is 0.05 MWh. This is the minimum amount of heat required to heat 1 m³ of domestic water. The price of water heating is also affected by the circulation cost, which can appear on the invoice as the circulation cost (towel dryer) or heating (summer heating).

Your building manager can share more detailed information about the cost of heating 1 m³ of water in your circumstances.

According to the District Heating Act, only the apartment association of an apartment building can enter into a contract for the supply of heat.

District Heating Act § 10 clause 1.1

(1.1) In case the property is divided into apartments, the joining party is the apartment association. An apartment owner can join directly if it is possible to connect their consumer installation to the network through a connection point that meets the requirements of this law.

In most cases, buildings connected to district heating consume heat all year round to heat domestic water. In a building with district heating, heat consumption, including the beginning and end of heating, is mostly automated and there is no need to manually turn the heating off and on. As a rule, the automation of the heating substation of the building is tuned to the desired parameters and regulates the heating of the building depending on the temperature of the outside air. The desired parameters are jointly agreed upon by the owners of the building.

If the building’s owners or residents have decided to turn off the heating substation for the warm period then, in order to start the heating, the building manager must open the heating valves in the building’s heating substation, turn on the pump, and check the automation settings when it is to be turned back on. Notification of Utilitas or the presence of a representative is not necessary. However, before turning on the heating substation, it is worth checking whether the heating system inside the building is in working order and filled with water. Particular attention should be paid to this in buildings where the heating system has been repaired or where the radiators were replaced during the summer.

If there is only cold water and hot water is unavailable, check for a heating failure in the building.
Information about interruptions is available on the website. If there is no heating failure, contact the building manager. If there is no water at all, there is a water cut or some work is being done in the building.

Information about heating interruptions can be found on our website.

If there is emergency damage in the heating pipeline, please notify the Utilitas customer support manager in your area.

In the e-service portal, you can see consumption data and comparisons with buildings of the same type, heating substation parameters, invoices, valid contracts, and other documents. It is possible to submit a request for an API key in the e-service in order to receive consumption data to your own automation system.
