Heating period

When does the heating period begin/end?

The rules for heat and hot water supply are regulated by the Decree of the Ministry of Industry and Trade No 237 / 2014 Coll.

The heat supply will start in the heating period when the average outdoor air temperature at the location drops below +13°C in 2 consecutive days and weather conditions cannot be expected to increase above +13°C for the next day.

Heating of apartments and non-residential premises in residential and non- residential buildings will be reduced or interrupted in the heating period if the average daily outdoor air temperature at the location exceeds +13°C in 2 consecutive days and weather conditions cannot be expected to decrease for the next day. Limitations of using heat are performed to meet the requirements of their thermal attenuation and ensure the thermal stability of the room. The heating is restored with the subsequent decrease of the average outdoor air temperature below +13°C.

During the heating period, apartments and other rooms are heated between 6.00 and 22.00 hours.

The heating takes place outside the heating period in the case of approval of at least two-thirds of final consumers, the outdoor temperature conditions require it and the technical and supply conditions allow it.

Calculation of average daily temperature

he average outdoor air temperature is determined as a quarter of the sum of outdoor temperatures measured in the shade, excluding the radiance effect of the surrounding areas. Measurements are made at 7:00 am, at 2:00 pm and at 9:00 pm, and the temperature measured at 21:00 is counted twice.
