Karaganda is preparing for the upcoming heating season

In Karaganda, the heating season is approaching quickly, and preparation actions are being intensified to face the harsh winter ahead. This vast city in Kazakhstan, known for its cold winters, invests each year in optimizing the infrastructure related to district heating and heat supply. In 2025, the municipality is implementing a series of ambitious measures to ensure reliable and efficient central heating, thus avoiding the inconveniences related to energy outages and failures of thermal networks. The key role of repairs, upgrades, and maintenance is at the heart of these preparations, in order to ensure all residents optimal comfort and control over energy costs.

Current state of heating infrastructure in Karaganda before winter

Preparing for the heating season is not limited to merely activating boilers. In Karaganda, the robustness and reliability of various heat supply systems are scrupulously examined. According to the latest information provided by the akimat, more than 2,500 residential buildings are affected, of which 75% are already ready to face winter temperatures. However, there are still about 115 “heavy” buildings, those that require significant work on the central heating system.

This work must be completed before September 15 to avoid any major breakdowns during the winter season. Among the buildings equipped with so-called “end-of-line” district heating systems—more fragile thermal circuits under particular monitoring—164 have already undergone thorough maintenance. However, 152 buildings remain under close observation to ensure optimal heat supply.

In the face of these challenges, emphasis is placed on the rigor of interventions and prioritization of critical buildings. The municipality of Karaganda, through Mayor Meiram Kozhukhov, has emphasized that residential and social facilities, such as schools and hospitals, are subject to weekly inspections to check their condition and operation during winter.

• 75% of buildings ready for the cold season
• 115 heavy buildings undergoing major work
• 164 buildings maintained this year
• 152 buildings identified as end-of-line with increased monitoring

This data illustrates a rigorous organization at the local level, essential to face the harshness of the continental climate characteristic of Karaganda. To deepen your understanding of the climate and its impacts on preparation for cold seasons, consult specialized sites such as Numbeo Climate Karaganda or Meteoblue.

Modernizations and repairs of water and electricity networks: foundations of effective district heating

Ensuring efficient central heating cannot be done without robust water and electricity infrastructure. In Karaganda, significant modernization work is underway ahead of the heating season. In 2025, about 20 km of drinking water supply networks and 3 km of sewage networks are under repair.

This work aims to improve the tightness of pipes, reduce leakage risks, and optimize the flow of hot water necessary for the proper functioning of central heating installations. According to data from the municipality, these efforts have reduced the wear of water networks to about 59%, and that of sewage networks to 82%. These figures reflect a notable advance toward better sustainability of essential infrastructures.

At the same time, electrical networks are also at the heart of the work. Overhead lines, underground cables, substations, and distribution points are undergoing a rigorous renovation program, jointly carried out by Karaganda Zharyk and Karaganda Energosalasy. The goal is to ensure stable power supply for district heating equipment. This ensures that heaters, pumps, and other thermal equipment will not be subject to variations or outages that could disrupt heat supply.

• 20 km of drinking water networks under repair
• 3 km of sewage networks under renovation
• Renovation of power lines and substations in progress
• Reduction of wear to 59% (water) and 82% (sewage)

These results are part of the “Investment tariff” program, which funds both the work and the modernization of equipment directly related to the production and distribution of thermal energy. This program is an effective example of integrating local and national policies to improve energy performance. For more practical information on the distribution and maintenance of heating networks, you can consult Prime Coup de Pouce Heating.

Infrastructure	Length (km)	Wear before work (%)	Wear after work (%)	Status
Drinking water network	20	80	59	Under repair
Sewage network	3	90	82	Under repair
Power lines and substations	N/A	N/A	N/A	Renovation effective

Priority programs and local projects for a controlled heating season in Karaganda

Beyond the renovation of existing networks, Karaganda is developing innovative projects to sustainably improve district heating and heat supply. A major priority is connecting the village of Shakhterskoye to the centralized heating system. This project aims to provide reliable heating to this community by the end of the year and reduce dependence on often costly and less efficient individual systems.

At the same time, the construction of three new kindergartens in the region marks a strong commitment to social infrastructure. These buildings will benefit from modern facilities, adapted to current energy standards, with efficient heating ensuring both comfort for children and control over energy expenses.

These initiatives are part of a comprehensive vision to improve living conditions in Karaganda. They particularly promote the use of economic and ecological solutions, in line with recent developments in the heating market that can be explored on Prime Coup de Pouce Heating. The goal is also to support each step of the local energy transition, through a progressive offer of renewable energy production equipment suitable for the urban context.

• Connection of the village of Shakhterskoye to central heating
• Construction of three new kindergartens
• Implementation of modern and energy-efficient equipment
• Compliance with 2025 energy standards for public buildings

This favorable framework benefits the optimized management of district heating, thereby reducing the city’s carbon footprint. To delve into the issues of sustainable heating networks, it is interesting to explore resources such as sustainable heating and cooling networks or the technologies of high temperature heat pumps.

Technical and logistical challenges to ensure effective heating during winter in Karaganda

Karaganda faces particular challenges due to its harsh continental climate. Winter temperatures can fall well below zero, often varying between -10°C and -19°C in January, the coldest month. This context requires robust and reliable heating, with systems that can withstand extreme variations while optimizing energy consumption.

Heating circuits must therefore be inspected and maintained scrupulously to avoid any risk of freezing, blockage, or premature wear. The existence of buildings with “end-of-line“ heating also indicates an increased complexity in network management, with segments where temperature and flow may be more difficult to maintain.

Maintaining an efficient district heating system entails several imperatives:

• Regular inspection of boilers and heat pumps to identify anomalies
• Checking the tightness of piping to prevent leaks of water or heat
• Continuous monitoring of distribution points in end-of-line buildings
• Preventive maintenance to limit breakdowns during the cold season
• Optimized management of energy consumption to reduce costs and environmental impact

Correct sizing of district heating installations thus ensures a homogeneous and sufficient distribution of heat, in compliance with current standards. For those interested in the technique, the site Prime Coup de Pouce Heating offers a detailed presentation of the requirements for efficient and sustainable installations.

Action	Description	Objective
Boiler inspection	Verification of functioning and maintenance	Prevent breakdowns
Tightness tests	Detection of leaks in pipes and fittings	Maintain energy efficiency
Maintenance of end-of-line networks	Enhanced monitoring and targeted interventions	Ensure reliable distribution in sensitive areas
Energy control	Monitoring of consumption for optimization	Reduce energy bill
