According to the report, the global Boiler market is projected to expand from USD 82.7 billion in 2025 to USD 150.9 billion by 2035, registering a CAGR of 6.2%, the highest during the forecast period. The global boiler market expanding, pushed by efficiency improvements and the process of converting heating systems in buildings and industrial facilities to electricity, which is rapidly moving towards high efficiency condensing boilers and hybrid boilers. For instance, At ISH 2025, Bosch and other manufacturers also exhibited condensing boilers of small size and high efficiency, plus hybrid solutions to HVAC, which contribute to the transition to energy-saving heating technologies. This driver is boosting the demand towards compact and high-efficiency boiler systems and will facilitate long-term expansion of replacement and retrofit installation.
Additionally, the growth of the boiler market, backed by robust government attention to energy use, emissions and clean heating, via regulations, incentives and social infrastructure initiative. For instance, in 2025, the UK government expanded its Boiler Upgrade Scheme, encouraging adoption of low-carbon and high-efficiency heating systems across residential and commercial buildings. Government actions are promoting prevalence of low-carbon and high-efficiency boilers and increasing market demand and accelerating the process of rehabilitating legacy systems.
“Key Driver, Restraint, and Growth Opportunity Shaping the Global Boiler Market”
The expansion of the boiler market is constrained by the fact that there is the shortage of qualified workforce who is familiar with the operation, maintenance and problem solving of high efficiency, hybrid and artificial intelligence-based boiler systems. This skills gap aggravates adoption particularly in emerging economies and smaller plants and factories that limit the spread of more technologically advanced boiler technologies.
The increasing focus on energy efficiency (via the incorporation of waste heat recovery systems) is improving the boiler market opportunities. The recovered heat can be used in industries such as cement, steel, chemical production in a bid to cut down on fuel consumption, severe emissions, and improve overall operations in the industries.
