CO2 Heat Pump Water Heater Market Size (2022-2027):

The Global CO2 Heat Pump Water Heater Market size was valued at US$ 1.42 billion in 2021 and is anticipated to reach US$ 2.45 billion by 2027 and increase at a CAGR of 6.88% between 2022 and 2027.

The system has several advantages over other Heat Pump Water Heaters, including a reduction in primary energy usage of more than 75%. In addition, the rising demand for energy-efficient heaters in developed countries like Europe and Japan propels the CO2 Heat Pump Water Heater Market forward. Over the projected period, the increasing demand for HPWH from commercial and residential areas and district heating projects is expected to give profitable chances for the CO2 heat pump water heater market to develop.

Market Drivers:

The increasing demand for energy-efficient heaters in emerging economies is the primary factor responsible for the global CO2 heat pump water heater market growth during the forecast period. Similar to refrigerators, a CO2 heat pump water heater is introduced as a compressor. Instead of discharging heat into the atmosphere, the HPWH collects heat from the environment and pumps it into a water tank. When compared to typical HPWH systems that utilize propane or HFC as a working fluid, the HPWH system using CO2 as a working fluid can achieve a 20% higher COP. Heat pump water heaters are ideal for less hot water applications, such as in small business operations and the residential sector, including single-family residences and multi-family structures. This heater's 10–20kW segment is simple to operate and has high operational efficiency. Nursing homes, hotels, hospitals, sports facilities, and residential constructions all use these heaters daily. Because of their environmental and cost-saving benefits, these heat pumps have acquired widespread acceptance and approval.

Furthermore, government initiatives in several nations are supporting the growing need for geothermal heat pumps. Again, one of the most promising solutions for reducing greenhouse gas emissions is a heat pump water heater. Through aerothermal and geothermal technology, a heat pump water heater gives an energy-efficient approach to supply heating. As a result, adopting heat pump water heater systems instead of fossil fuel-based systems can dramatically lower carbon emissions coupled with energy use and generation. Nonetheless, technological improvements, Internet of Things (IoT)-enabled heat pump water heater systems, and untapped potential in emerging countries point to positive growth prospects. Moreover, the increasing number of heat pump water heaters installations in commercial, industrial, and residential segments acts as the crucial factor in fueling the global CO2 heat pump water heater market growth in the upcoming years. 

Market Restraints:

All end-user sectors are unaware of heat pump water heaters' cost efficiency, energy efficiency, and environmental benefits. It is because they are generally thought to be costly. These are the potential limitations to the global CO2 Heat Pump Water Heater Market's overall growth. In addition, a lack of awareness regarding the uses of heat pump water heaters in emerging economies hinders the global CO2 heat pump water heater market growth during 2021-26. Furthermore, a new generation of CO2 heat pump generates much higher temperatures and avoids the high global warming potential of standard refrigerants.

On the other hand, heat pumps are of high cost and are difficult to install. Moreover, in cold weather, heat pumps raise more issues and can damage the system. Therefore, in cold weather, heat pumps cannot generate high efficiency.

Moreover, heat pumps rely on electricity to operate and have a high coefficient of performance. The installation process of heat pumps requires enough work and disruptions to the house and the garden. Moreover, heat pumps are expensive, which is the most challenging to install. These are some of the factors responsible for hampering the global CO2 heat pump water heater market during the foreseen period.

Market Segmentation:

CO2 Heat Pump Water Heater Market - By Product:

  • Air Source
  • Water Source

Based on product, the air source segment plays a dominant role in the global CO2 heat pump water heater market in the near future. Most residential sectors utilize air sources due to their lower installation cost and eco-friendly technology, which further propels the global CO2 heat pump water heater market growth. The energy for heating is extracted from the air by an air source heat pump water heater. Instead of using a fluid-like ground or rainfall, this heat pump water heater is usually situated outside and absorbs thermal energy from the environment. In colder areas, the technique of absorbing outside heat uses less fuel than typical electric resistance heating systems and gas boilers, resulting in lower electricity usage and easier market penetration.

On the other hand, the water source segment tends to grow with the highest CAGR in the market. Depending on whether there is power available for heating, water source heat pumps absorb thermal energy from water, then pumped between a compressor/condenser unit and an electric heater core. Thus, they work in the same way that air source heat pump water heaters do, but without the need for additional components like fans or ducting, making them simple to install and maintain even in small spaces. This characteristic makes it appropriate for residential applications where installation requirements could be complex if not planned ahead of time.

CO2 Heat Pump Water Heater Market - By Application:

  • Residential
  • Commercial
  • Industrial

Based on application, the residential sector held the highest global CO2 heat pump water heater market share because of its energy-efficiency technology and several government subsidies to increase the demand for heat pump water heaters. Electric resistance heating is used in the home use of CO2 heat pump water heaters, using an electrically powered fan to circulate the air, which is then cooled by passing through a coil before being vented back into the room. Depending on the local environment and weather circumstances, it can be utilized as a primary or secondary house heating source. In addition, depending on space constraints and hot water demand, the appliance may be positioned at a central location or on each building floor.

Market Regional Analysis: 

The CO2 Heat Pump Water Heater Market Report includes the segmentation of Regions:

  • North America
  • Europe
  • Asia Pacific
  • Latin America
  • Middle East & Africa

Asia Pacific attributes the largest global CO2 heat pump water heater market owing to the increasing government initiatives to propel the demand for heat pump water heaters and rising the use of renewable energy and energy-efficient products.

North America is estimated to grow with the highest CAGR in the global CO2 heat pump water heater market due to the several changes made by the emerging economies including U.S. and Canada, through their effects in lowering the CO2 emissions.

Latin America is anticipated to have significant global CO2 heat pump water heater market revenue owing to the growing environmental awareness and modified infrastructure to lower the emissions of greenhouse gases.

Impact of COVID-19 on CO2 Heat Pump Water Heater Market:

When it came to the impact of COVID-19 on the CO2 heat pump water heater industry, suppliers reported similar concerns to those seen in the local construction industry: most projects that had already begun slowed down, while others were canceled. In addition, some HVAC manufacturers' production lines had to be halted for many weeks, and sanitary regulations hampered installers' new installation projects. Meanwhile, the policies to nudge the market toward more energy-efficient structures and products have proven effective. As a result, a significant number of private households and project owners have embraced their new ways of life by renovating their homes. Installers also took advantage of opportunities to improve their skills and highlight the benefits of heat pumps. This, together with financial assistance for replacing no longer used heating systems, helped to reverse the drop in new-build sales. Overall, heat pump sales in most of the countries continued to rise.
