Boiler Water Treatment Chemical market size was valued at US$ 5,992.5 Million in 2025, expanding at a CAGR of 10.3% from 2026 to 2033.
Boiler water treatment chemicals are specifically designed chemicals that treat feed water and boiler water, inhibiting scaling, corrosion, and steam entrainment, contributing to boiler protection. The process system that is normally utilized in this regard has been configured in such a way that it has a reducing agent to eliminate the dissolved oxygen, an alkaline buffer/phosphate to control the pH value, a threshold inhibitor, a chelating agent to prevent hardness scale deposition, and a foam inhibitor and amine to protect the steam condensate system. These chemicals are supplied from the injection tank via a metering pump and controlled automatically using conductivity and pH meters.
Boiler Water Treatment Chemical Market- Market Dynamics
Rising Demand for High-Efficiency Boilers to Drive Market Growth
The increased application of modern boiler water treatment chemicals can be attributed to the rising requirement for energy-efficient boilers as companies keep on producing energy-efficient boilers in order to enhance efficiency, prevent boiler corrosion and scaling, increase its lifespan, and abide by strict environmental regulations. For instance, in the Air Conditioning: Saving Lives and Accelerating Net Zero report published by the British Progress Org, it is estimated that there are 23 million households in the UK that are still relying on gas boilers despite the slow installation of air source heat pumps in the country; only 40,000 to 50,000 heat pumps are installed annually in existing houses. When replacing your typical gas boiler, you will have to pay approximately (US$4,400), but if you install an air source heat pump, you will be charged (US$17,600) without any grants (£6,500 / US$8,800 with the £7,500 / US$10,100 government grant). Therefore, the demand for advanced boiler water treatment chemicals is anticipated to increase.
The Global Boiler Water Treatment Chemical market is segmented on the basis of Type, End Use, Chemistry, Conditioning Method, and Region.
The oxygen scavengers segment represents a notable share in the Boiler Water Treatment Chemical market because of the rise of chemicals used for scavenging dissolved oxygen in boilers, controlling the corrosive damage caused by the oxidized water, and maintaining the stability of equipment, which is one of the major drivers behind the growth of the boiler water treatment chemical market. For example, according to the European Environment Agency (European Union), in 2026, levels of biochemical oxygen demand (BOD) in European rivers are going to fall by half from the current ones, and a 20 percent reduction in the levels of ammonium is going to occur because of the efforts taken for sewage water treatment. Nevertheless, levels of biochemical oxygen demand (BOD) are going to stay almost unchanged on the level of 2.7 mg O/L, so there is still a need for oxygen scavengers and oxygen control to keep the dissolved oxygen balance. Therefore, boiler water treatment chemicals are expected to have steady growth worldwide.
Boiler Water Treatment Chemical Market- Geographical Insights
The Asia-Pacific Boiler Water Treatment Chemical market has been expanding with the help of robust industrial development, mounting generation of electricity capacity, and rise in manufacturing activity across the region. For instance, in July 2026, according to the Center for Research on Energy and Clean Air (Org), in China, thermal power commissioning reached a record level during the first five months of 2026 by increasing by 84% as compared to the previous year, while solar and wind capacity additions decreased by 70% and 46%, respectively, in the month of July 2026. This fall is due to a high base in 2025 before new electricity prices. These trends are expected to accelerate demand for boiler water treatment chemicals across Asia-Pacific industries.
North America is the key player in the global boiler water treatment chemicals industry due to environmental regulations, sustainable water management policies, and growing demands to improve boiler efficiency. For instance, in September 2025, according to the Government of Canada, Canada is making more efforts to ensure sustainable water management. In this context, withdrawals of water and water return after use in Canada have increased to around 22,903 million cubic meters on average, 256.5 m3 per million Canadians, and 78 m3 of annually renewable fresh water per person. Also, because Canada possesses around 20 percent of the fresh water in the world and 7 percent of annually renewable fresh water in the world, there has been an increase in the direction of policies in the field of management of freshwater resources and efficient use of water. This regulatory and resource foundation continues to accelerate demand for advanced boiler water treatment chemicals.
The global boiler water treatment chemicals market is characterized by a high level of competition, with major players such as BASF SE, Kemira, Kurita Water Industries Ltd., Solenis, and Ecolab focusing on strategic alliances, consistent research and development, and increasing their portfolio of products. In June 2026, Kurita Water Industries Ltd. entered into an agreement with Membrane Group India to establish their joint venture called "Kurita Membrane India Pvt. Ltd." The joint venture provides advanced technology for water treatment and strengthens their presence in the growing Indian industrial and semiconductor water treatment market. Such growth strategies are expected to spur innovation and competitiveness in the market.
In November 2025, Solenis successfully completed its takeover of NCH Corporation and, with an improved breadth of its product and service offerings, extended its portfolio of water treatment and industrial hygiene products globally as well as increased its capabilities in industrial lifespan, water management, and customer service in 160 countries.
In October 2025, BASF SE signed a definitive agreement with Carlyle Group and Qatar Investment Authority for the sale of its automotive OEM coatings, refinish coatings, and surface treatment operations. This is yet another strategic enhancement to the company's portfolio, enabling it to focus on innovation in its specialty chemicals solutions for industrial and water industries.
