The heating, ventilation, air conditioning, and domestic hot water sector is undergoing a significant shift, largely driven by sustainability, digitalization, and energy efficiency. By 2025, key trends in the industry are moving towards a greater integration of clean technologies, the development of hybrid solutions, and an increasing use of renewable gases like biomethane and green hydrogen, deemed essential for decarbonization.
In this scenario, the replacement market has begun to show signs of recovery, fueled by the need to replace outdated equipment. This revitalization comes after years of excess inventory that impacted the sector, with both distributors and manufacturers moving towards a more sustainable model. Meanwhile, the new construction market remains stable, focusing on energy rehabilitation and prioritizing energy efficiency and compliance with stricter regulations related to sustainable building.
Bosch Home Comfort recently introduced the Compress 5800i AW heat pump, noted for its low environmental impact due to the use of natural refrigerant R290. This model is compatible with renewable energies, such as solar photovoltaic, making it an ideal option for energy rehabilitation in older buildings thanks to its compact design and quiet operation.
The use of renewable gases emerges as one of the pillars for decarbonization, offering viable alternatives in applications where electrification is less feasible. Biomethane and green hydrogen are seen as key sources to complement electrical solutions and accelerate the energy transition. Vicente Gallardo, sales director of Bosch Home Comfort, emphasizes that decarbonization does not rely solely on electrification. From his perspective, renewable gases will play an essential role in the energy transition, and Bosch is committed to developing solutions that incorporate these technologies.
Bosch has also adapted its condensing boilers to be compatible with biomethane and hydrogen mixes of up to 20%. Moreover, it is exploring pilot projects in the United Kingdom with green hydrogen, ensuring its solutions remain viable in the long term.
The combination of combustion boilers and heat pumps in hybrid systems is gaining popularity, as they offer a more gradual energy transition without the need for a complete system overhaul. These systems allow consumers to benefit from the efficiency of electrification during periods of high demand and elevated prices.
Aerothermal energy is gaining prominence in new construction projects due to its ability to efficiently provide heating, cooling, and domestic hot water.
Sustainability also influences production and design processes in the sector, with circular economy principles such as the use of recycled materials and maximizing equipment durability. Bosch is committed to reducing its environmental impact throughout its entire value chain.
The sector’s expansion will be favored by strategic acquisitions and the development of cutting-edge technologies. In 2024, Bosch completed a significant acquisition of Johnson Controls-Hitachi Air Conditioning, solidifying its position as a global leader in heating, ventilation, air conditioning, and domestic hot water solutions.
Although public funds, such as the Next Generation programs, have had a limited impact so far, it is expected that greater alignment between government policies and market needs will drive the sector’s growth in the coming years. The recovery of consumer confidence and moderating energy prices act as catalysts for this growth.
In conclusion, hybrid technologies, connected systems, and the rise of renewable solutions will determine the course of the sector towards 2025. The integration of renewable gases with advanced technology, such as heat pumps and condensing boilers, establishes an effective strategy not only for decarbonization but also for creating a more sustainable and resilient future at both residential and industrial levels.
