When to turn the heat on?

In autumn, when the outside temperature starts to cool down and the weather forecasts promise precipitation, the need to turn on a building’s heating system appears. When is the right time to do it?

When the cool and damp autumn weather arrives, construction experts recommend starting heating earlier in the season, as it helps to maintain a suitable indoor climate in the building and prevent excessive humidity in the rooms. Low outside temperatures and humidity can have a detrimental effect on building structures, which ultimately require a larger amount of heat to warm up. This, in turn, means an increased cost for customers.

However, the start of the heating season is up to the customers themselves. In order to find a consensus on the issue of a start date, the heat consumers of the building must monitor the outer air temperature as well as the humidity level and temperature inside the building. Thus, customers decide on the start of the heating period based on their needs and the characteristics of the building.

It is recommended to start heating the building when the average daily air temperature drops below 12 °C. Most commonly, the indoor air temperature of the building should stay between 20-22 °C.

To start heating, the building manager must open the heating valves in the heating substation of the building, turn on the pump and check the automation setting. 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 radiators replaced during the summer. If no heat appears when the input dampers of the house are opened, please contact Utilitas customer service at klienditugi@utilitas.ee, phone 610 7107.
