Boiler Water Treatment Chemicals Market Report 2026

The boiler water treatment chemicals market size has grown rapidly in recent years. It will grow from $4.26 billion in 2025 to $4.74 billion in 2026 at a compound annual growth rate (CAGR) of 11.2%. The growth in the historic period can be attributed to expansion of thermal power generation, growth of industrial boiler installations, rising demand for process steam, increasing focus on equipment longevity, availability of chemical water treatment solutions.

The boiler water treatment chemicals market size is expected to see rapid growth in the next few years. It will grow to $7.04 billion in 2030 at a compound annual growth rate (CAGR) of 10.4%. The growth in the forecast period can be attributed to increasing energy efficiency regulations, rising adoption of specialty treatment chemicals, expansion of industrial manufacturing capacity, growing demand for predictive maintenance solutions, increasing integration of automated water treatment systems. Major trends in the forecast period include increasing use of advanced corrosion inhibitors, rising adoption of boiler efficiency chemicals, growing focus on water quality optimization, expansion of specialty boiler treatment solutions, enhanced monitoring of boiler performance.

The growing demand for power generation is expected to drive the growth of the boiler water treatment chemicals market. Power generation facilities produce electricity by converting primary energy into mechanical and then electrical energy using generators. Chemical water treatment is essential for optimizing power generation efficiency and maintaining the stability of thermal equipment. For example, in June 2024, according to the International Hydropower Association (IHA), a UK-based non-profit organization, global installed hydropower capacity increased by 13.5 GW in 2023, reaching a total of 1,412 GW, with pumped-storage hydropower (PSH) capacity rising by 6.5 GW to 182 GW. Therefore, increasing power generation demand is supporting the growth of the boiler water treatment chemicals market.

Key companies in the boiler water treatment chemicals market are developing advanced solutions to prevent issues related to water usage, such as scale formation, metallic corrosion, sludge deposition, and boiler water carryover. For instance, in December 2023, Thermax Ltd., an India-based technology company, launched Maxtreat, a line of boiler water treatment chemicals designed to improve the operational efficiency and lifespan of boiler systems. Maxtreat minimizes scaling and corrosion, addressing critical factors that can cause system failures and increase maintenance costs, particularly in power generation and industrial manufacturing. This launch highlights Thermax’s commitment to expanding its portfolio and offering technologically advanced water treatment solutions.

In October 2025, Kemira Oyj, a Finland-based provider of sustainable chemical solutions for water-intensive industries, acquired Water Engineering, Inc. for approximately US$ 150 million in cash. This acquisition enhances Kemira’s presence in the boiler water treatment chemicals market by expanding its industrial water treatment services, including boiler, cooling tower, and wastewater treatment solutions. Water Engineering, Inc., based in the US, manufactures boiler water treatment chemicals and formulations.
