Aerothermal energy is one of the most efficient technologies for home air conditioning, harnessing the energy in the air to generate heating, cooling and domestic hot water (DHW). It is a sustainable solution that reduces energy consumption and CO2 emissions, offering homeowners a more efficient alternative to traditional systems.
In this article we will explain in detail how aerothermal energy works, what types of installations exist and what are the requirements and steps for its installation in new or existing homes. In addition, we will analyze its viability in apartments and single-family homes, the associated costs and the impact on the energy efficiency of the home.
What is aerothermal energy and how does it work?
Aerothermal energy is a technology based on heat pumps that extract thermal energy from the outside air to heat a home. It works through a thermodynamic cycle in which a refrigerant absorbs heat from the air, compresses it to increase its temperature and transfers it to the heating, cooling or DHW system. For a deeper understanding, it is advisable to review how aerothermal energy works in detail.
This process allows the heat pump to generate between 3 and 5 kW of useful energy for every kW of electricity consumed. This makes it a highly efficient option. compared to conventional systems such as gas or diesel boilers.
Types of aerothermal energy according to the distribution system
There are different systems for distributing heat or cold in the home using aerothermal energy:
- Aerothermal energy with underfloor heating: Ideal for heating and cooling as it distributes heat evenly.
- Aerothermal energy with low temperature radiators: It allows you to use conventional radiators, although with lower efficiency.
- Aerothermal energy with fan coils: Devices that operate with forced air, suitable for heating and cooling.
Requirements for the installation of aerothermal energy
Before installing aerothermal energy in a home, it is necessary to meet certain requirements to ensure its efficiency:
- Enough space: A suitable location for the outdoor unit is required, with ventilation and free of obstacles.
- Heating system compatibility: If conventional radiators are reused, it may be necessary to enlarge or replace them.
- Thermal insulation of the home: A well-insulated home maximizes system efficiency.

Steps to install aerothermal energy in a home
The installation of an aerothermal system requires a well-planned process, which includes:
- Housing evaluation: The existing air conditioning system and its needs are analyzed.
- Heat pump selection: The appropriate power and model are chosen according to the size of the home.
- Outdoor unit installation: It is placed in a place with sufficient ventilation.
- Connected to the air conditioning system: Underfloor heating, fan coils or radiators are installed.
- Start-up and adjustments: Operating parameters are verified.
How much does it cost to install aerothermal energy?
The cost of installing aerothermal energy varies depending on the size of the home and the complexity of the system. Generally speaking, prices range from:
- Between €5.000 and €10.000 for small homes or apartments.
- Between €12.000 and €20.000 for single-family homes with underfloor heating.
- More than €20.000 for large homes or those with advanced heat distribution systems.

Is aerothermal energy worth it in cold climates?
Many people believe that aerothermal energy loses efficiency in extremely cold climates. However, current models are designed to operate even in outside temperatures down to -20ºC. In these cases, it may be advisable to supplement the system with low-temperature radiators or underfloor heating to improve its performance.
Is it feasible to install aerothermal energy in apartments?
Yes, it is possible to install aerothermal energy in an apartment, although certain limitations must be taken into account:
- Location of outdoor unit: There must be space on the terrace, balcony or roof terrace.
- Permission from the community of neighbors: In shared buildings, permission may be required.
- Adaptation of the heating system: In some cases, radiators will need to be replaced with low-temperature models or fan coils.
For this reason, it is important to take into account aerothermal systems and their adaptation to homes such as apartments.
Aerothermal energy has established itself as one of the most efficient and sustainable alternatives for heating and cooling homes. Its capacity to generate heating, cooling and DHW with reduced energy consumption makes this system a profitable long-term investment. In addition, its versatility allows it to be installed in new homes, renovated houses or even in flats, provided that the appropriate technical requirements are met.
