Recommendations in the case of a heat service interruption

In the event of a heat service interruption, Utilitas immediately informs the building manager, who should then inform the consumers, residents, or tenants of the building(s) about the heat supply interruption, so those impacted can take this into account in their plans.

The supply of domestic hot water may also be interrupted if it is connected to the district heating service in the particular building(s). As cold water will run from the hot water tap but be read as hot water by the hot water meter during the interruption, we recommend not using the hot water tap during an interruption of the heating service.

If the interruption of the heating service is related to maintenance work on the district heating network, during which a pressure test is carried out, there may be dangerous pressure on the building’s heat supply system, which we inform customers about separately.

In case of service disruptions and failures, please inform customer service klienditugi@utilitas.ee or by phone +372 610 7107.

Recommendations in the event of a power outage

As a vital service provider, we guarantee district heating to our customers’ buildings even during power outages, using generators to produce heat and maintain the operation of the district heating network. However, since both the building’s heat substation and the heating system’s pumps require electricity, we suggest our customers think about how to ensure their building’s heating system remains functional in the event of a power outage.

If an in-house power outage occurs, heat will not circulate within the building, causing the water in the pipes to cool and the indoor temperature to gradually drop. In this case, the building will not be able to receive heat until the electricity supply is restored.

For short-term power outages, the building’s heating system will retain some warmth due to inertia in the pipes. While the indoor temperature will start to decrease, this may not be immediately noticeable in the event of a short-term power outage.

For long-term power outages, heat continues circulating in the building if the building’s heat substation is connected to a small generator. For this, the heat substation’s control panel must have an external power socket where a generator can be connected. In addition, a sufficient fuel supply must be available to keep the generator running.

If your building’s heat substation’s control panel doesn’t have an external power socket, it is not possible to connect a generator and the water in the pipes will begin to cool. Depending on factors such as outdoor temperature, building materials, and overall condition, there is a risk of pipes freezing during prolonged outages. To prevent this, we recommend monitoring power outage forecasts, keeping track of the building’s internal temperature, and draining the district heating pipes if there is a risk of freezing. Once the outage is over, the internal heating system must be refilled with water before heating can resume.
