Subject matter
This decree regulates
(a) heating and supply rules for hot commercial water;
(b) specific heat consumption indicators for heating and hot water preparation;
(c) requirements for the fitting of internal thermal equipment for buildings by instruments regulating the supply of heat energy to final consumers.
Scope
(1) This decree applies to central heating and central hot water preparation
(a) in dwellings and non-residential premises of rental, cooperative and occupant-owned residential buildings;
(b) in the operating premises of non-residential buildings.
(2) The Decree does not apply to buildings in which all apartments and non-residential premises are used by the sole legal or natural person who owns the building and to buildings in which heating is dealt with in accordance with a specific regulation.
Heating rules
(1) The heating season begins on 1 September and ends on 31 May of the following year.
(2) The heat energy supply shall be started in the heating season when the average daily outdoor air temperature at the appropriate location or location falls below + 13 ° C in two consecutive days and, according to weather developments, no increase above + 13 ° C for the following day is expected.
(3) The average daily outdoor air temperature is a quarter of the sum of outdoor temperatures measured in the shade, excluding the effect of radiating the surrounding areas at 7: 00, 14: 00 and 9: 00, the temperature measured at 21.00 hours is calculated twice.
(4) The heating of apartments and non-residential spaces in residential and non-residential buildings shall be restricted or interrupted in the heating season if the average daily outdoor air temperature at the appropriate location or location rises above + 13 ° C in two consecutive days and the weather trend indicates that the temperature is not expected to fall for the following day. If the average daily outdoor air temperature falls below + 13 ° C, the heating is restored.
(5) In case of agreement of at least two thirds of tenants (consumers), heating takes place outside the heating season, if the outdoor temperature is required and the technical and supply conditions allow it.
(6) During the heating season, the apartments are heated between 6.00 and 22.00 hours and the other spaces at the time of operation so that the average indoor air temperatures achieved provide the calculation temperatures of the internal air as determined by the project.
(7) The calculation temperature of the internal air determined by the project is the so-called resulting temperature, which takes into account the influence of the radiance of the surrounding walls in addition to the indoor air temperature. It is measured with a ball thermometer.
(8) The average indoor air temperature in heated rooms shall be measured by a thermometer shielded from the radiance of the surrounding surfaces and the effect of the sun, and shall be one quarter of the sum of the indoor air temperatures measured in the middle of the floor plan of 1 m above the floor surface layer at 8.00, 12.00, 16.00 and 21.00.
(9) In the period from 22.00 to 6.00 am, heating of the accommodation rooms and in the non-operational time of other heated spaces shall be restricted or interrupted in the short term to the extent necessary to comply with the requirements of their thermal attenuation ensuring the thermal stability of the rooms.
(10) During heating, in accordance with paragraph 6, in accommodation rooms and in other spaces with similar use equipped with a heating body, the corresponding average indoor air temperature measured by the thermometer shielded from the radiance of the surrounding areas and the effect of the sun on the number of indoor air calculation temperature determined by the project
- higher by 1 ° C in a room with one outside wall,
- higher by 1.5 ° C in a room with two outside walls,
- higher by 2 ° C in a room with three or more exterior walls,
- higher by 1 ° C in the room with excessive glazing.
(11) Heating to higher average indoor air temperatures in heated rooms is possible in the case of flats provided that more than two-thirds of the tenants are required and provided that indoor temperature limits are not exceeded in either apartments or non-residential areas.
(12) The limits of the average indoor air temperatures for flats and non-residential spaces in residential and non-residential buildings shall be determined by an increase in the average indoor temperatures determined in accordance with the principles set out in paragraphs 6, 10 and 11 by 2 ° C, or by temperatures determined in non-residential areas by technological regulations or established expert expertise.
(13) Common heated spaces in residential buildings and non-residential spaces in residential and non-residential buildings are heated during the heating season at the time of their operation to ensure the calculation temperature of the internal air determined by the project.
(14) The heating of non-residential spaces in residential and non-residential buildings shall be restricted or interrupted on days when they are not operated to meet the requirements of their thermal attenuation ensuring their thermal stability.
(15) The design calculation temperatures of the internal air of selected residential and non-residential spaces are laid down in a separate legislation.
(16) The planned repairs, maintenance and revision work, which may result in a restriction or interruption of the heating supply, are carried out outside the heating season.
Rules for the supply of hot commercial water
(1) Hot commercial water is supplied year-round so that it is at a consumer outlet temperature of 45 ° C to 60 ° C, except for the possibility of a short-term decrease at the time of peak consumption in the unit of account.
(2) The delivery referred to in paragraph 1 shall take place daily at least between 6.00 and 22.00.
(3) The delivery to non-residential buildings shall be interrupted on the dates on which the buildings are not operated if technically possible.
(4) The unexceeded thermal energy consumption limits for the supply of hot commercial water are equivalent to the specific consumption for its preparation and the supply increased by 50% from the values referred to in § 5 (1) (b).
(5) A summer break in the supply of hot commercial water due to planned maintenance within 14 days shall be agreed between the supplier and the customer, who shall notify it at least 10 days before the start of the service to all consumers.
Measurements of heat energy consumption for heating and the supply of hot water for use in new or modified buildings
