The commercial building sector is responsible for approximately 13% of global greenhouse gas emissions, with space and water heating accounting for the majority of that share. For years, addressing these emissions seemed technically challenging. Heat pumps were expensive. Green hydrogen was unavailable. But electric boilers? They have been commercially available for decades. The missing ingredient was not technology—it was policy and economic alignment. That alignment has now arrived. According to the Market Research Future report, decarbonization in commercial heating is the single most powerful trend driving the market toward a 4.651 billion USD valuation by 2035. The primary tool for achieving this decarbonization is accelerated electric boiler adoption , particularly in the space heating and water heating applications that dominate commercial energy use.
What Decarbonization in Commercial Heating Actually Means
Decarbonization in commercial heating is not a single action but a portfolio of strategies. It includes: (1) eliminating onsite fossil fuel combustion, (2) reducing total energy consumption through efficiency, (3) electrifying thermal loads using zero-carbon electricity, and (4) participating in demand flexibility programs that support grid integration of renewables. Electric boilers address all four strategies simultaneously. They produce zero onsite emissions (strategy 1). They achieve 99% efficiency, far higher than gas boilers (strategy 2). They run on electricity that can be sourced from renewables (strategy 3). And they can modulate instantly in response to grid signals (strategy 4). No other commercial heating technology offers this complete alignment with decarbonization goals.
The Policy Pipeline: What Is Coming by 2035
The report provides a detailed forward look at policies that will accelerate decarbonization in commercial heating through 2035. In the European Union, the revised Energy Performance of Buildings Directive (EPBD) requires all new commercial buildings to be zero-emission by 2028 and all existing buildings to be renovated to zero-emission standards by 2035. In the United States, the Inflation Reduction Act’s 179D tax deduction offers up to 5.00 USD per square foot for energy-efficient commercial heating equipment, including electric boilers. At the local level, over 50 U.S. cities have now enacted bans on natural gas hookups in new construction. The report notes that these policies are not speculative—they are already being enforced. For a specifier designing a building today, specifying a gas boiler would risk non-compliance with building codes that will take effect before the building is even completed.
End-Use Sector Transformation: Healthcare and Hospitality Lead
The report’s end-use analysis reveals which sectors are furthest along in decarbonization in commercial heating. Healthcare facilities currently hold the largest market share for electric boilers. Hospitals have realized that electric boilers offer superior reliability (no fuel deliveries needed during storms) and safety (no combustion byproducts in patient areas). The report projects the healthcare segment to reach 1.227 billion USD by 2035. However, the fastest-growing end-use for electric boiler adoption is hospitality. Major hotel chains have made net-zero pledges. Installing electric boilers in new hotel construction is the most straightforward way to demonstrate progress toward these pledges. The report projects the hospitality segment to grow to 1.392 billion USD by 2035, overtaking healthcare by the early 2030s.
The Industrial Angle: High-Temperature Applications
One common question about decarbonization in commercial heating is whether electric boilers can replace gas boilers in high-temperature industrial applications. The report addresses this directly. For processes requiring temperatures below 150°C—which covers the vast majority of commercial heating (space, water, and many industrial processes)—electric boilers are fully capable. For higher-temperature applications, the report notes emerging solutions such as electrode-type electric boilers that can produce high-pressure steam, and thermal storage systems that use electric resistance to heat ceramic or molten salt blocks during off-peak hours. The report highlights recent developments such as AtmosZero raising 21 million USD to commercialize zero-emission industrial electric boilers, indicating that the industry is actively closing the high-temperature gap.
Practical Guidance for Specifiers and Procurement Teams
For engineers and procurement professionals writing boiler specifications today, the report offers clear guidance on incorporating decarbonization in commercial heating into procurement documents. First, specify that the boiler must be capable of modulating to match load without short-cycling (all electric boilers meet this). Second, require integration readiness with building management systems and demand response programs (specify BACnet or Modbus communication). Third, include a total cost of ownership analysis over 15 years that accounts for carbon pricing escalation. Fourth, prioritize vendors who offer extended warranties on heating elements and controls. The report identifies key players including Thermo-Dynamics, Fulton, A. O. Smith, and Bosch as having mature product lines suitable for large-scale deployment.
The 2035 Vision
By 2035, the report envisions a commercial heating landscape where fossil fuel boilers are the exception, not the rule. The Commercial Electric Boiler Market will have grown from 2.138 billion USD in 2024 to 4.651 billion USD in 2035. Decarbonization in commercial heating will be the new baseline, not a differentiator. Electric boiler adoption will be standard practice across healthcare, hospitality, education, and office sectors. The only remaining question is not whether to electrify, but how quickly. For building owners and specifiers, the answer should be: start now. The policies, the technology, and the economics are finally aligned.
