Aerothermal energy for Domestic Hot Water: operation and types.

An efficient and sustainable alternative

The constant search for efficient and sustainable energy alternatives has led to the development of innovative systems to cover our daily needs, such as the production of domestic hot water (DHW) in our homes.

One of these technological advances is aerothermal energy for DHW , a system that has gained popularity thanks to its efficiency and its contribution to the reduction of electricity consumption and greenhouse gas emissions.

In this article, we will explore in detail what it is, how it works, its advantages, the different types available on the market and when it can be a cost-effective option for your home.

What is aerothermal energy for ACS?

Aerothermal energy for ACS is a domestic hot water production system that uses the energy present in the outside air to heat the water we use in our homes or businesses.

This system consists of a tank and a heat pump that are responsible for capturing, transferring and storing heat from the air to provide hot water efficiently and sustainably.

Operation of aerothermal energy for Domestic Hot Water

Aerothermal energy takes heat from the outside air and transfers it to the water in the tank to heat it.

This process is carried out through a closed circuit that uses a refrigerant gas to absorb and release heat, ensuring optimal performance in various climatic conditions.

The main components that make this cycle work are:

  • Compressor: Compresses the refrigerant gas by reducing its volume, this causes its temperature to increase to heat the water.
  • Condenser:  It is always located at the outlet of the compressor and through which the refrigerant in the form of vapor gives energy to the water in the tank because it is thermally hotter than it. As the energy is released, it condenses and returns to a liquid state.
  • Expansion valve: Sharply reduces the pressure and temperature of the refrigerant fluid so that the cycle begins again.
  • Evaporator: Allows the exchange between the refrigerant fluid and the outside air. In this exchanger the refrigerant fluid goes from liquid to saturated vapor state.

Types of aerothermal energy for Domestic Hot Water

There are several types of aerothermal systems for hot water, each with its own characteristics and advantages. The main ones are:

  • Compact aerothermal: This type of system integrates the water tank and the heat pump in a single module. Its installation is simple in interior spaces, and its price is usually more affordable.
  • Monobloc aerothermal: In this case, the water tank is located inside the home, while the heat pump is located outside.
  • Retrofit aerothermal: It is a heat pump designed to be installed in existing water tanks, which makes it a highly efficient and profitable option for the renovation of old installations.

When is it worth purchasing an aerothermal system for DHW?

The decision to invest in an aerothermal system for DHW will depend on various factors, such as hot water consumption, the climate of the area, the space available for installation and the available budget.

In general, this type of system is usually more profitable in homes with moderate hot water consumption and in regions with temperate climates, where the energy from the outside air can be made the most of.

Finally, we recommend installing solar panels at home and taking one more step in the efficiency of your home.
