Industrial Boilers Market

The industrial boilers market is worth USD 16,864.0 million in 2025 and reaches USD 28,731.2 million by 2035, compounding at 5.47% a year. The figure is built bottom-up: roughly 124,000 industrial boilers shipped in 2025 across gas and oil fired boilers, solid fuel boilers including coal and biomass, electric and electrode boilers, and waste heat and heat recovery boilers, at an average realised price of USD 136,000 per boiler, triangulated against industrial steam demand, installed base replacement and manufacturer disclosures. Boilers shipped grow 2.6% a year with industrial activity and fleet replacement, while price per boiler rises 2.8% a year as low emission, electric and high efficiency designs take share. Industrial heat pumps are covered in a separate report and excluded here. This study sits within our thermal power equipment and services coverage and follows the published Douglas Insights methodology.

How is industrial heat being decarbonised?

Slowly and unevenly, because industrial steam and hot water are overwhelmingly produced by burning fossil fuels in boilers, and the alternatives each fit only part of the need. Industry uses heat for cooking, drying, sterilising, distilling, chemical reactions and countless other processes, and boilers burning natural gas, oil or coal supply much of it, making industrial heat one of the largest sources of emissions. Several routes to decarbonise it are emerging. Industrial heat pumps can supply low and medium temperature heat very efficiently and are covered in our separate heat pump coverage. Electric boilers, including electrode boilers, convert electricity directly into steam at high temperatures and can switch on when renewable electricity is cheap and plentiful, providing flexibility to power grids. Biomass boilers burn wood and agricultural residues, and some boilers are being adapted to burn hydrogen. Meanwhile, tighter air pollution rules are forcing replacement of old, dirty boilers, particularly small coal boilers. The result is a market where total boiler numbers grow modestly but the mix shifts toward cleaner and electric boilers. The exclusive chapter of this report compares the cost of steam by technology and region, since relative fuel and power prices decide the choice.

What does this market include?

This study covers boilers that produce steam and hot water for industrial processes and facilities. Gas and oil fired boilers cover fire tube and water tube boilers burning natural gas, oil and similar fuels, the largest category. Solid fuel boilers cover boilers burning coal, biomass, and waste, including fluidised bed designs. Electric and electrode boilers cover boilers heated by electric elements or by passing current directly through water, able to produce high pressure steam. Waste heat and heat recovery boilers cover boilers that capture heat from exhaust gases of engines, turbines and industrial processes. Utility power station boilers, residential and small commercial heating boilers, industrial heat pumps, and gas turbines sit outside the boundary. Value is measured at the price industrial buyers pay.

Why are electric boilers gaining ground?

Because they produce zero emissions at the site, can be powered by renewable electricity, and can help balance grids that increasingly rely on variable wind and solar. An electric boiler converts nearly all the electricity it uses into heat, but because electricity is usually more expensive than gas per unit of energy, electric boilers historically made sense only where electricity was cheap. That is changing. In regions with large amounts of wind and solar, electricity prices at times fall very low or even negative when generation is plentiful, and industrial sites can run electric boilers during these periods, often alongside a conventional boiler or heat storage, cutting both costs and emissions. Carbon pricing raises the cost of burning gas, improving the comparison. Grid operators also value large electric boilers as flexible demand that can absorb surplus power. The main constraints are grid connection capacity, since large electric boilers need substantial power, and electricity costs in regions without cheap renewables. The model reflects electric boilers as the fastest growing category, concentrated in regions with abundant renewable power and carbon pricing.

What drives demand?

The first driver is industrial activity. Manufacturing, food processing, chemicals, pulp and paper, textiles and other industries require steam, and industrial growth drives boiler demand.

The second driver is emissions regulation. Air quality rules limiting nitrogen oxides, sulphur dioxide and particulates force replacement of old boilers with cleaner designs, and bans on small coal boilers in some regions accelerate replacement.

The third driver is decarbonisation. Carbon pricing and corporate emissions targets drive adoption of electric, biomass and high efficiency boilers.

The fourth driver is energy efficiency. High fuel costs encourage replacement of inefficient boilers and installation of heat recovery boilers.

What restrains the market?

Three restraints are modelled. Industrial cyclicality is the first: boiler purchases follow industrial investment and can be deferred in downturns. Competition from heat pumps is second: for low and medium temperature heat, industrial heat pumps can displace boilers entirely, reducing boiler demand in those applications. Long equipment life is third: industrial boilers last decades, so replacement demand in mature markets is gradual.

Which categories carry the value?

Gas and oil fired boilers lead with 48% of 2025 value, USD 8,094.7 million, the dominant industrial steam source. Solid fuel boilers, including coal and biomass, hold 30%, USD 5,059.2 million, with coal declining and biomass growing. Electric and electrode boilers account for 12%, USD 2,023.7 million, and grow fastest with decarbonisation and cheap renewable power. Waste heat and heat recovery boilers contribute 10%, USD 1,686.4 million, supported by efficiency goals. Each category is modelled through 2035 by industry and region.

Where are industrial boilers installed?

Asia Pacific leads with 46% of 2025 value, USD 7,757.4 million, growing 5.8% a year, driven by China’s large industrial base and its replacement of small coal boilers, and industrial growth in India and Southeast Asia. Europe holds 20%, USD 3,372.8 million, at 5.0%, where carbon pricing and emissions rules drive electric and biomass boilers. North America holds 20%, USD 3,372.8 million, at 4.8%, with replacement of ageing boilers and emissions rules. The Middle East contributes USD 1,011.8 million at 6.2%, Latin America USD 843.2 million at 5.4% and Africa USD 505.9 million at 6.0%. Six regional models sum to the global figure, with country tables in the Excel model.

Who makes industrial boilers?

A mix of global and regional manufacturers compete. Babcock and Wilcox, Thermax, Cleaver-Brooks, Bosch Industriekessel, Viessmann, Miura, Hurst and Fulton supply industrial boilers across fuel types and regions, and Valmet and Andritz supply large biomass and recovery boilers. Parat, Vapec and others specialise in electrode boilers. Chinese manufacturers including Taishan Group and Zhengzhou Boiler supply large domestic volumes, and Indian manufacturers serve South Asia. The competitive chapter profiles each manufacturer’s product range, fuel and electric capability, service network and regional presence.

How are industrial boilers priced?

Average realised price is USD 136,000 per boiler in 2025, spanning a wide range from small packaged fire tube boilers costing tens of thousands of dollars to large water tube and biomass boilers costing millions. Low emission burners, advanced controls and heat recovery add cost, and electric boilers vary with capacity and voltage. Installation, fuel handling for solid fuel boilers, and emissions control equipment can add substantially to project cost. The shift toward low emission, electric and high efficiency designs raises average price, which is the reason for the positive price leg. The pricing chapter publishes price bands by category and capacity.

How do the scenarios diverge by 2035?

The base case carries 2.6% growth in boilers and 2.8% growth in price per boiler for a 5.47% revenue CAGR and USD 28,731.2 million in 2035. The heat-pump-substitution scenario, in which industrial heat pumps displace more boilers and industrial investment slows, sets the legs at 1.2% and 1.8%, landing near USD 22,600 million. The rapid-replacement scenario, in which emissions rules and carbon pricing accelerate replacement with electric and low emission boilers, sets them at 3.6% and 3.8%, carrying the market past USD 34,400 million. Each 1-point change in boiler growth moves the 2035 figure by roughly USD 2,720 million.

Which rules and standards apply?

Three layers matter. Air emissions regulation comes first: limits on nitrogen oxides, sulphur dioxide and particulates for combustion plants, including rules for medium sized combustion plants in Europe and coal boiler restrictions in China, drive replacement and cleaner designs. Pressure equipment and safety regulation is second: boilers are pressure vessels subject to strict design, manufacturing, inspection and certification requirements. Carbon and energy policy is third: carbon pricing, efficiency standards and incentives for renewable heat shape the choice between fuel, biomass and electric boilers. The regulatory chapter maps these requirements by jurisdiction.

Where will boilers lose ground to heat pumps?

Industrial heat pumps are becoming a serious competitor to boilers, but mainly for lower temperature heat, which defines where boilers remain essential. Heat pumps are very efficient at supplying heat up to around 100 to 150 degrees Celsius, which covers many applications in food and beverage, pulp and paper drying, and some chemical processes, and in these uses they can replace gas boilers with much lower energy use and emissions. For higher temperature steam, however, required by many chemical, refining and industrial processes, heat pumps are less mature or unsuitable, and boilers, whether gas, biomass or electric, remain necessary. The likely outcome is that heat pumps take a growing share of low temperature heat while boilers remain dominant at higher temperatures, with electric and low emission boilers growing within that space. The model reflects this split, with boiler demand growing modestly overall.
