District heating market seen topping $232 billion by 2030

The Business Research Company projects the global district heating market will reach $232.3 billion by 2030, driven by urbanization, decarbonization policies and wider use of renewable and waste heat. Western Europe remains the largest region, while combined heat and power systems are set to dominate the market mix.

Why it matters: - District heating is becoming a bigger piece of urban energy infrastructure as cities look for lower-carbon ways to heat homes, offices and institutions. - The market forecast signals steady demand for centralized systems that can cut energy waste and support decarbonization goals. - The segment is also part of a much larger machinery market, giving suppliers, utilities and investors a clearer view of where growth is concentrated.

What happened: - The Business Research Company projected the global district heating market will reach $232.3 billion by 2030. - The report estimated the market will grow at a 5% CAGR through 2030. - The company also said the market will surpass $232 billion by 2030 and represent nearly 4% of the broader machinery sector’s projected $5,280 billion value that year. - The report was published as The Business Research Company’s District Heating Global Market Report 2026. - The source release was dated Oct. 12, 2026.

The details: - Western Europe is expected to remain the largest regional market, reaching $70 billion by 2030 from $57 billion in 2025. - Western Europe’s growth reflects upgrades to aging heat infrastructure, investment in low-carbon urban energy systems, greater use of waste heat and supportive government policy. - The U.S. market is forecast to reach $46 billion by 2030, up from $37 billion in 2025. - U.S. growth is tied to district energy adoption on institutional campuses, urban infrastructure projects and efforts to reduce long-term building energy costs. - Combined heat and power systems are projected to be the leading plant type by 2030 with 61% market share, equal to $141 billion. - The report said CHP demand is supported by higher efficiency, decentralization of heat production and improvements in fuel use and reliability. - The market is also segmented by heat source, including coal, natural gas, renewables, oil and petroleum products. - The market serves residential, commercial and industrial applications. - The report said rapid urbanization and smart city programs are adding about 2.2% annually to growth. - Government rules and incentives for decarbonization and energy efficiency are adding about 2.0% annually to growth. - Renewable energy and waste heat integration are adding about 1.8% annual growth through 2030. - The report highlighted industrial byproducts, geothermal energy, biomass, solar thermal and large heat pumps as part of that shift. - Engie SA held the No. 1 global market position in 2025 with a 9% share, according to The Business Research Company. - Veolia Environnement SA had 8% share in 2025, Vattenfall AB had 7%, and E.ON SE, Ørsted A/S, and RWE Aktiengesellschaft each had 1%. - Danfoss A/S, Helen Oy and Fortum Oyj each held 0.3% share, while Vital Energi Utilities Limited held 0.2%. - The top 10 firms accounted for 27% of total revenue in 2025. - The report described the industry as moderately fragmented. - The release said the market faces high capital needs, strict environmental and efficiency standards and complex network construction. - The report also identified frequent utility partnerships, broad product portfolios and innovation as key competitive advantages. - Veolia launched the ecothermal grid in the United Kingdom in November 2025, a low-carbon heat network with AI-driven smart controls, energy storage and waste heat recovery. - The report said future growth will also come from fourth-generation district heating, intelligent heat distribution, thermal energy storage, hybrid heat generation and digital network optimization. - Combined heat and power, boiler and other plant type segments are forecast to add more than $45 billion in value by 2030. - CHP is expected to add $27 billion, boilers $12 billion and other plant types $6 billion between 2025 and 2030. - The report named a wide set of major participants, including Engie SA, Veolia Environnement SA, Vattenfall AB, E.ON SE, Ørsted A/S, RWE Aktiengesellschaft, Danfoss A/S, Helen Oy, Fortum Oyj and Vital Energi Utilities Limited.

Between the lines: - The forecast points to a market where growth is less about new demand alone and more about replacing older systems with lower-carbon, digitally managed networks. - The dominance of Western Europe suggests policy and infrastructure maturity still matter as much as raw market size. - CHP’s projected lead shows the market still favors systems that can deliver both heat and power efficiently, even as renewable inputs expand.

What's next: - District heating growth will likely track city-level infrastructure spending, emissions policy and utility investment decisions through 2030. - Market share could keep shifting toward firms that combine network construction, low-carbon generation and digital controls. - The report pointed to continued opportunity in smart heat management, storage and hybrid systems as operators look to improve efficiency and cut emissions.

The bottom line: - District heating is moving from a niche infrastructure category to a mainstream decarbonization play, with Europe leading the transition and CHP still anchoring the market. - More information is available in the company’s report and the sample request page.
