The water-based heating and cooling systems market size is expected to see strong growth in the next few years. It will grow to $51.49 billion in 2030 at a compound annual growth rate (CAGR) of 6.7%. The growth in the forecast period can be attributed to rising demand for sustainable hvac solutions, increasing regulatory push toward energy efficient buildings, growing smart building adoption, expansion of heating and cooling infrastructure upgrades, rising inclination toward eco friendly temperature management. Major trends in the forecast period include increasing deployment of energy efficient water based climate control, rising adoption of hydronic heating and cooling infrastructure, growing shift toward eco friendly building temperature management, expansion of smart controlled water circulation systems, rising integration of advanced water based hvac components.

The growing construction activities are expected to drive the expansion of the water-based heating and cooling systems market in the future. The construction industry involves the processes of building, renovating, and maintaining structures and infrastructure, including residential, commercial, and industrial projects. The industry's growth is fueled by factors such as rising urbanization, population growth, and government investments in infrastructure development. Water-based heating and cooling systems are essential in the construction sector due to their energy efficiency, cost-effectiveness, and ability to maintain a comfortable and consistent indoor climate in both residential and commercial buildings. For example, in July 2024, the United States Census Bureau, a US-based government agency, reported that the value of construction operations increased from $2.01 trillion in May 2023 to $2.14 trillion in May 2024. As a result, the growing construction activities are boosting the growth of the water-based heating and cooling systems market.

Leading companies in the water-based heating and cooling systems market are focusing on developing advanced products, such as the Combined Heat and Power (CHP) Solution, to gain a competitive advantage. A CHP Solution is an integrated system that generates both electricity and useful thermal energy from a single fuel source, enhancing overall energy efficiency and reducing greenhouse gas emissions. For example, in August 2023, Bloom Energy, a US-based green energy company, introduced an advanced CHP solution for the Bloom Energy Server. This high-efficiency energy generation system uses solid oxide fuel cell technology to produce clean electricity and high-temperature steam. This innovative solution helps industrial and commercial customers reduce energy costs and carbon emissions while improving overall energy efficiency.

In May 2024, Rheem Manufacturing Company partnered with Renew Home to provide innovative heating and cooling solutions. This collaboration enhances Rheem's offerings with Renew Home's no-cost energy management program, helping customers reduce energy consumption and costs. Renew Home specializes in energy management solutions in the US market, complementing Rheem's expertise in residential and commercial water heaters and boilers.
