Aerothermal heating is a renewable and efficient source of energy that significantly reduces your heating costs.
We spend 65% of our energy costs on heating our homes.
A cost that can be much lower if we choose more efficient and sustainable options, such as aerothermal energy. This method allows the heat present in the air to be extracted from the outside environment in order to be used by the air conditioning system inside any single-family home. It‘s a free, renewable energy that saves on domestic consumption and reduces the environmental footprint.
How many parts does an aerothermal heating system have and how do they work?
These units consist of an outdoor unit, an indoor unit and an emitter system.
- Outdoor unit
- Indoor unit or hydrokit
- Emitters
Outdoor unit
The outdoor unit is placed on the façade of the building or dwelling and is responsible for capturing the heat from the environment.

Indoor unit or hydrokit
The indoor unit absorbs this heat through a water circuit.

Emitters
We enjoy a pleasant temperature inside our home thanks to the emitters, which radiate the heat inside our home. The most common are underfloor heating, fan coils or radiators.

Energy efficiency
One of the main advantages of the aerothermal heating system is its ability to supply more useful energy than it needs to operate. In other words, it provides much more heat in terms of energy than the electricity it uses to generate it. Under normal conditions, for every kW consumed, it generates 4 kW in the form of heat.
Therefore, the electrical energy required by the system accounts for 25% of the total energy produced. The remaining 75% comes from the air, free of charge. This is the energy that the aerothermal system extracts from the outside ambient air. As a result, the energy efficiency of aerothermal equipment is between 300% and 400%.
Enjoy the temperature you want, even in summer.
One of the best qualities of aerothermal energy is that it offers both heating in winter and cooling in summer. The heat pump system of these arrangements has a reversible operation. It’s capable of extracting heat from the interior rooms and directing it to the outside so that we can enjoy cool spaces during the hottest months.
Enjoy maximum comfort and the temperature you want regardless of the time of year thanks to a single system, Daikin Altherma.

Aerothermics, the renewable energy that air-conditions your home
Aerothermal energy is a renewable, inexhaustible and free energy that comes from the air and allows us to obtain heating, air conditioning and domestic hot water.
How does Aerothermics work?
- The atmosphere captures the energy emitted by the sun.
- Heat Pump technology captures that renewable energy from the air.
- That energy is used in our home through the outdoor unit which sends it to the indoor unit.
- The indoor unit heats the water and produces heating and domestic hot water.
- In summer, the heat from our home is sent outside to produce air conditioning.
Aerothermics makes it easier to integrate the use of renewable energies in the domestic environment and the consequent reduction of CO2 emissions into the atmosphere.
