Aerothermal heat pump

The aerothermal heat pump succeeds in extracting energy from the outside air to heat, cool and heat the domestic hot water in the installation.

How does it achieve this? The aerothermal heat pump works on the principle of thermodynamics, for heating it extracts heat from the air and introduces it into the house and for cooling it extracts heat from the house and transports it to the outside.

The most efficient aerothermal heat pumps are the so-called air-to-water heat pumps, so called because they extract heat from the air and transfer it to the water, unlike an air conditioner (air-to-air heat pump) that extracts heat from the air and transfers it to the interior through the air, being unable to heat domestic hot water (DHW).

Thanks to the high performance of aerothermal heat pumps, we can multiply electricity consumption by 3, 4 and 5 (depending on the external conditions and the installation), i.e., with 1 kW of electricity consumed we can generate 3 kW to 5 kW of thermal energy.

At Ecoforest we have focused our aerothermal range on air-water and monobloc style heat pumps.

All about aerothermal heat pumps

One of the great advantages of the heat pump is the ability to heat, cool and domestic hot water (DHW) with the same equipment. The aerothermal heat pump extracts heat from the air in winter to heat the installation and the DHW. In summer, the aerothermal heat pump transports the heat inside the house to the outside, thus reducing the temperature.

Air conditioning is a type of aerothermal heat pump of the air-air type, this means that it extracts energy from the air and transmits it to the interior of the installation through the air, so air conditioning cannot be used with underfloor heating, radiators and cannot heat DHW. In addition, air conditioning is less efficient, more polluting due to the large amount of refrigerant it uses, and more expensive to maintain.

The monobloc aerothermal heat pump is of the air-water type, as it exchanges heat with the outside air and transmits it to the inside via water. Monobloc refers to the fact that all the components of the aerothermal heat pump are located in the outdoor unit.

It is a type of aerothermal heat pump in which all the components of the heat pump are in the outdoor unit, making it a very compact and easy to install system. The indoor unit usually has different models, some more basic ones consisting only of the control screen and others more complex with hydraulic kits and even domestic hot water tanks.

Both systems use the heat pump, the only difference is the medium from which the energy is obtained, in the case of aerothermal energy it is obtained from the air, but in geothermal energy it can be obtained from the ground and from water.

Heat pumps use energy to run the compressor, a component of the heat pump, but this electricity consumption is minimal compared to the energy that is extracted from the air in the case of aerothermal energy and from the ground or water in the case of geothermal energy. The heat pump can generate from 1 kW of electricity consumed up to 5 kW of useful thermal energy for the air conditioning of the house. Thanks to these high efficiencies, large savings can be achieved.

The monobloc aerothermal heat pump is a very compact air-conditioning system, so the technical room is very simple and small in size. The installation consists of an outdoor unit and an indoor unit. The great advantage of the aerothermal system is that it avoids duplicating systems as it produces heating and cooling.
