What is aerothermal system?

Aero means Air and therm is a thermal unit for measuring heat.
Aerothermy is a state-of-the-art heat pump system that saves energy to heat or cool the air.
The heat pump is a machine for making heat and cold that uses a circuit similar to that of refrigerators.
There are two types of Aerothermal: air-air and air-water


Exchanges heat with outside air to heat or cool the inside.


Exchanges heat with a water system.
In this case, systems such as heating, cooling and the production of domestic hot water are centralized.

Our professional recommendation:

In our architecture studio in Barcelona, ​​we recommend installing in your renovated positive home:

  • aerothermal system only for hot water
  • heat pump or minisplits for heating and cooling with R32 gas

For these reasons:

  1. energy saving and efficiency
  2. economic savings (aerothermal for heating is too expensive and not so efficient, minisplits are way more efficent and have room-by-room control)
  3. environmentally friendly system
  4. possibility of energy support by solar panel (if neighbours are OK and comply with the billion regulations of the Barcelona city hall -low probability-)

What’s the price of Aerothermal system?

For a 150m2 house with one floor, 3 bedrooms and 2 bathrooms, the cost of the Aerothermal machine only water and its installation is about € 4,000 +taxes.
If you install fan coils through ducts in main rooms, the cost of material and installation is around € 3,000 +taxes.
For very efficient miniplits connected to the WIFI and control room by room count around 1.000€+taxes  per each machine (installed).
