Global District Heating Market size and share is currently valued at USD 199.73 billion in 2024 and is anticipated to generate an estimated revenue of USD 327.20 billion by 2034, according to the latest study by Polaris Market Research. Besides, the report notes that the market exhibits a robust 5.1% Compound Annual Growth Rate (CAGR) over the forecasted timeframe, 2025 - 2034
Market Overview
District heating is a system of distributing heat generated in a centralized location to meet residential and commercial heating needs across multiple buildings via an underground network of insulated pipes. These systems are primarily powered by heat produced from CHP plants, biomass, geothermal sources, industrial waste heat, and increasingly, solar thermal installations.
The model promotes greater energy efficiency, lower carbon emissions, and enhanced reliability in heating provision — all while supporting urban development and circular economy objectives. As energy markets become more focused on sustainability, district energy systems are expected to play a pivotal role in the transition to net-zero economies.

Country-Wise Market Trends
Germany
Germany leads Europe in district heating development, driven by its commitment to climate neutrality and fossil fuel phase-out. Over 14% of the country’s heat demand is met via centralized heating systems, predominantly powered by CHP plants and biomass. Key urban centers like Berlin and Hamburg are upgrading legacy systems into 4th generation district heating networks, integrating renewable heat sources such as solar thermal and industrial waste heat.
Government initiatives under the National Energy and Climate Plan (NECP) and subsidies for municipal heating transformation have attracted both domestic and foreign investment in modern thermal infrastructure.
Denmark
Denmark remains a global pioneer in thermal energy distribution, with district heating supplying more than 65% of the total heat demand. Municipal ownership, stringent environmental regulations, and widespread public acceptance have enabled the integration of renewable heat sources, including surplus wind and solar energy.
Cities like Copenhagen and Aarhus have successfully adopted CHP and large-scale thermal storage to optimize seasonal load variations. Denmark's policy framework serves as a model for transitioning countries looking to decarbonize their heating sectors.
China
China is the world’s largest district heating market by volume, serving over 500 million urban residents. While historically dependent on coal-fired boilers, the country is shifting towards cleaner technologies through extensive investment in CHP units, natural gas, and waste-to-energy systems.
As part of the “Clean Heating Plan”, the government is actively replacing coal-based systems with renewable heat sources in northern provinces such as Hebei, Shanxi, and Heilongjiang. Smart metering and digital heat controls are being rolled out nationwide to improve efficiency and reduce emissions.
Russia
Russia has one of the oldest and most extensive centralized heating systems globally, covering more than 70% of residential and public buildings. However, aging infrastructure and high heat losses have led to major overhauls funded by both state and private capital.
New pilot projects in cities like Moscow and St. Petersburg focus on reducing transmission losses and incorporating CHP and waste heat recovery technologies. Legislative efforts are underway to improve transparency in energy billing and facilitate modern network deployment.
Sweden
Sweden’s district heating sector is a benchmark for sustainable heating, with more than 90% of systems powered by renewable energy and waste incineration. The country has aggressively phased out fossil fuels and now relies heavily on biomass, geothermal, and CHP for urban thermal supply.
Municipalities such as Stockholm and Gothenburg use smart, integrated systems that combine heat generation with real-time demand forecasting, ensuring efficient thermal energy distribution throughout residential zones.
United Kingdom
The UK government has identified district heating as a critical component of its net-zero strategy, particularly for decarbonizing dense urban areas. New builds and retrofitting projects are expanding in cities like London, Manchester, and Leeds, where CHP-powered systems are being installed in mixed-use developments.
The Green Heat Network Fund (GHNF) is channeling substantial funding into local authority-led heat networks that integrate renewable heat sources, such as large-scale heat pumps and wastewater recovery.
United States
Although the U.S. has a lower market penetration of district heating (approx. 5% in urban areas), there is growing momentum in campuses, military bases, and downtown business districts. CHP systems dominate installations at universities (Harvard, Stanford) and hospitals.
States such as Massachusetts, Minnesota, and California are actively exploring policy and investment strategies to expand centralized heating systems, focusing on carbon reduction and resiliency.
South Korea
South Korea has embraced district heating in urban planning, with significant systems operational in Seoul, Incheon, and Busan. Operated largely by Korea District Heating Corporation (KDHC), the networks are expanding to new smart cities and incorporate waste heat from incineration and industrial processes.
