The heat pumps have managed to carve out a fundamental niche in modern air conditioning. This type of technology is consolidating itself as one of the more efficient and versatile options to decarbonize homes and buildings, thus helping to achieve the energy and environmental goals set across Europe. Research and new solutions are enabling these systems to meet the demands of both new construction buildings as well as the growing need for energy rehabilitation in existing homes.
One of the key factors for the mass adoption of heat pumps is the adaptability to various urban environments, including situations with very limited space or strict safety requirements. Recent technological advances have resulted in new models compact and highly efficient, capable of being integrated into all types of homes without the need for major works or technical complications.
Advances in geothermal heat pumps for urban environments
The development of smart geothermal heat pumps is gaining ground especially in dense residential areas, as demonstrated in pioneering projects in cities such as Madrid. These facilities stand out for their capacity to provide heating and cooling efficiently, while minimizing the building's environmental impact and carbon footprint. Furthermore, innovative design and replicable project execution open up new opportunities in previously inaccessible niches for sustainable air conditioning.
Compact solutions: R290 propane heat pumps for renovation
Among the latest developments in the sector, the following stand out: Compact heat pumps with natural refrigerant R290. This type of technology, presented by companies such as ait-group, allows the equipment to be installed inside the home, eliminating active ventilation and thus reducing the cost and complexity of the works. Thanks to the use of a minimal amount of propane (less than 150 g) and modular systems that facilitate transport and installation in narrow spaces, they become a very interesting alternative for the energy rehabilitation of old buildings.
El propane R290 It is a natural refrigerant with a very low global warming potential, in accordance with new European regulations restricting fluorinated gases. Despite propane's inherent flammability, the new designs minimize risks and strictly comply with legislation, opening the door to a massive decarbonization in the residential area.
In terms of performance, these models offer outstanding figures: SCOP up to 5,14 at 35°C and the maximum energy rating A+++In addition, they incorporate integration with home automation systems, compatibility with solar panels, and intelligent home energy management capabilities.
Practical examples and future perspectives
This technology is already being tested in pilot projects in Germany and Italy, which replaces old diesel boilers and achieves energy consumption reductions of up to 60% while maintaining thermal comfort. The possibility of installation in small spaces is especially valuable in residential communities or buildings with limited outdoor space.
The European market is preparing to massively incorporate these solutions, supported by public subsidies, new favorable regulations, and the growing demand for cleaner and more economical technologies. This trend is expected to stimulate further innovation in natural refrigerants and promote increasingly modular and easy-to-install systems.
Development of heat pumps for domestic hot water in small homes
Other firms such as Thermor have opted for wall-mounted heat pumps for the production of domestic hot water (DHW), available in compact sizes of 100 and 150 litersThese units, designed for homes with limited space, also incorporate R290 refrigerant and stand out for their especially low noise level (starting at 38 dB). The largest model achieves a SCOP of 3,8, and both Wi-Fi remote control and anti-corrosion protection systems ensure efficient operation and a long service life.
This proposal represents a clear response to the needs of today's homes, where more and more is required efficiency, sustainability and integrationTo learn more about efficient air conditioning technologies, we invite you to visit our section on natural thermal insulators for our home.
Innovation in heat pumps for cold climates
The development of heat pumps adapted to cold climates is another highlight of the sector. Examples such as the Infinity Ultimate Cold Climate Heat Pump have demonstrated that it is possible to guarantee optimal performance even in sub-zero temperaturesThese systems are capable of operating efficiently down to -30°C, reducing the dependence on auxiliary heating and achieving significant economic and energy savings for users.
In addition to savings and sustainability, low noise levels and advanced connectivity improve the user experience and allow for a intelligent and convenient system management even in extreme situations.

Heat pumps are becoming established as a practical and forward-looking solution for air conditioning and hot water supply in all types of homes and buildings. Thanks to technical innovation, the use of sustainable refrigerants, and the support of European legislation, their implementation is facilitating the transition toward a cleaner and more efficient energy model, with direct benefits for both users and the environment.
