Aerothermal energy has become one of the best options for efficient and sustainable air conditioning in homes in 2025. Thanks to their ability to generate heating, cooling and hot water with very low consumption, more and more people are choosing to install these systems in their homes.
But what are the best aerothermal brands in 2025? In this guide you will discover a complete analysis with comparisons and opinions of the most outstanding equipment on the market. We will analyze their characteristics, advantages and key aspects to consider before choosing the ideal model for your home.
What is aerothermal energy and why is it a key technology in 2025?
Aerothermal energy is a technology that uses the energy of the outside air to efficiently heat a home. It works using heat pumps that extract heat from the air to generate heating in winter and cooling in summer, as well as providing domestic hot water (DHW) all year round.
This system is much more efficient than gas boilers or traditional electric systems, since It can generate up to five times more energy than it consumes. In addition, it is a greener alternative due to its lower impact on emissions. CO₂ and its compatibility with photovoltaic solar installations.

Key aspects when choosing an aerothermal system
Before making a decision, it is essential to take into account some key factors that will influence the performance and efficiency of aerothermal energy.
1. Team power
Choosing the right power is essential to ensure good performance and efficiency. A device with little power will not be able to heat the home properly, while one that is too powerful will increase consumption unnecessarily.
2. System type: Monobloc or Bibloc
Aerothermal energy can be:
- Monobloc: The entire system is integrated into a single outdoor unit. Easier to install and maintain.
- Bibloc: Composed of an outdoor unit and an indoor unit, it offers greater efficiency and flexibility.
3. Compatibility with existing heating
If you are going to replace a gas boiler, make sure that the chosen aerothermal system is compatible with radiators or underfloor heating. This is crucial to ensure good performance of the entire installation.
Aerothermal energy has established itself as one of the best options for heating and cooling homes in an efficient and sustainable way. Brands such as LG, Panasonic, Mitsubishi and Vaillant offer highly efficient models with advanced technology that guarantees savings and comfort. Before choosing a device, it is essential to analyze its characteristics, compatibility with the existing installation and level of energy efficiency to ensure maximum performance and savings at home.
