The heat pump booster for dhw market size is expected to see rapid growth in the next few years. It will grow to $3.64 billion in 2030 at a compound annual growth rate (CAGR) of 13%. The growth in the forecast period can be attributed to increasing investments in building electrification, rising demand for high-capacity dhw systems, expansion of district and centralized hot water systems, growing adoption of smart dhw management solutions, increasing regulatory support for low-emission heating. Major trends in the forecast period include increasing adoption of high-temperature heat pump boosters, rising demand for waste heat recovery systems, growing integration of smart control modules, expansion of retrofit applications for dhw systems, enhanced focus on energy-efficient hot water generation.

The tightening energy efficiency requirements in buildings are expected to stimulate the growth of the heat pump booster for domestic hot water (DHW) market in the future. Energy efficiency standards in buildings include regulations and guidelines established by authorities to reduce energy consumption through improved design, construction, and operation practices. The adoption of these standards is increasing as governments aim to lower energy use, reduce operating costs, and limit environmental impact. Heat pump boosters for DHW support energy efficiency goals by offering highly efficient water heating solutions that consume less electricity while meeting updated building codes. For example, in December 2024, according to the United States Department of Energy, residential buildings complying with the 2024 International Energy Conservation Code achieved average national savings of 7.8% in site energy, 6.8% in source energy, and 6.6% in energy costs compared with the previous code. Therefore, the tightening energy efficiency requirements in buildings are reinforcing the growth of the heat pump booster for domestic hot water market.

Leading companies operating in the domestic hot water (DHW) heat pump market are concentrating on developing advanced energy-efficient systems, such as integrated air-to-water heat pumps, to decrease energy consumption, lower carbon emissions, and offer versatile heating solutions for residential properties. Air-to-water domestic hot water (DHW) heat pumps refer to systems that draw heat from surrounding air and transfer it to water for household use, frequently supporting multiple applications such as radiant floor heating, forced air systems, and chilled panels, while delivering high efficiency and environmentally sustainable operation. For instance, in March 2025, Carrier Global Corporation, a US-based intelligent climate and energy solutions company, launched its first Domestic Hot Water Air-to-Water (DHW A2W) Heat Pump at the International Builders’ Show (IBS). This product is intended for both new construction and retrofit applications and features a compact outdoor unit, advanced refrigerant technology, a Coefficient of Performance (COP) of up to 4.9, and flexible tank integration, delivering significant energy savings, reduced carbon emissions, quiet performance, and smart controls for improved user convenience and sustainability.

In January 2024, Carrier Global Corporation, a US-based building automation technology company, acquired Viessmann Climate Solutions for an undisclosed amount. With this acquisition, Carrier sought to broaden its range of energy-efficient and renewable heating products, reinforcing its leadership in intelligent climate systems while expanding its presence in heat pump and domestic hot water markets. Viessmann Climate Solutions Berlin GmbH is a Germany-based provider of renewable climate technologies including heat pumps, heating systems, and integrated energy solutions for residential and light commercial use.
