Space Heating Boilers Market Growth & Trends

The global space heating boilers market size is expected to reach USD 38.87 billion by 2033, registering a CAGR of 3.5% from 2026 to 2033, according to a new report by Grand View Research, Inc. Rapid construction spending coupled with favorable government measures such as the installation of energy-efficient products are expected to benefit the space heating boiler market. For instance, the ENERGY STAR website states that through 2032, federal income tax credits for energy-efficient home upgrades would be offered under the Inflation Reduction Act of 2022. Consumers may successfully migrate to a sustainable energy future by utilizing tax credits and any applicable subsidies, thereby driving market growth.

The primary energy consumption in the U.S. accounted for 16% of the primary energy consumed globally in 2021, according to the U.S. Energy Information Administration. Despite having about 4% of the world's population in 2021, the U.S. ranked 10^th in the world for primary energy use per person. Due to the methods of sourcing, transportation, and potential for leaks that could increase methane emissions, the use of major energy sources such as natural gas and LP gas has raised environmental concerns. Thus, growing environmental concerns coupled with rising demand for energy-efficient products are expected to drive the demand over the forecast period.

Space heating boilers are a crucial part of the heating systems in both residential and commercial applications. Condensing space heating boilers are another effective technology that can heat buildings and produce domestic hot water. As they 'condense' the water vapor created during combustion into liquid form, they are referred to as 'condensing' processes. To warm the cold water entering the boiler, the heat from the water vapor is recycled. By using this procedure, it is made sure that most of the energy generated during combustion is used to heat the building. These factors are further expected to propel the market demand in the coming years.

Large commercial space heating boilers can be purchased with the help of the Federal Energy Management Program. For low-pressure steam water boilers used in commercial applications with a rated capacity ranging from 2,500,000(Btu/h) to 10,000,000 (Btu/h), the FEMP's acquisition guidelines and efficiency standards apply. The ENERGY STAR program covers both small commercial and residential space heating boilers. Thus, growing demand for energy-efficient solutions coupled with increasing government guidelines for high energy-efficient products is expected to drive the market demand.

Manufacturers of space heating boilers are looking for product launches, contracts, mergers & acquisitions, and expansions to develop new products. In July 2023, ThermaForce is a platform of extremely high-efficiency condensing gas boilers and water heaters that Rheem, a manufacturer of water heating and HVACR systems, introduced for the residential market. The platform also offers game-changing features for a variety of installation scenarios.
