Why AEROTHERMIA for Hot Water?

What is aerothermal energy?

The term aerothermal energy is currently much abused, but what is it really? It is a concept that is used to define the action of extracting the energy contained in the air to use it through a heat exchanger together with a thermodynamic cycle for, for example, air conditioning or heating water in our home throughout the year. Actually, systems that allow heat transfer between media have existed for decades, and they are none other than the so-called heat pumps. Specifically, aerothermal heat pumps are those that transmit heat by extracting it from the AIR. Therefore, aerothermal heat pump systems are only one of the possible current heat transfer systems between media: other types of heat pumps are, for example, air-to-air, water-to-air, water-to-water, etc.

But these teams have been in existence for many years, why now the boom in aerothermal heat pumps? The reason is simple: the technical evolution of these devices has enabled achieve very high energy efficiencyto the point of aerothermal energy is considered as a renewable energy source.
Exactly, in the current regulations of the Technical Building Code: DB-HE corresponding to the Basic Document "Energy Saving". in its section HE-4 corresponding specifically to the '...'.Minimum contribution of renewable energy to cover Domestic Hot Water demand The minimum contribution for ACS is established as follows through renewable energy sources at least 70% or 60% (depending on the daily DHW volume) . Thus, and due to the current high efficiency of aerothermal heat pumps, HE-4 itself, allows to consider aerothermal energy as another renewable energy source, provided that the final energy production significantly exceeds the consumption of primary energy used. Thus, in order to be considered a renewable energy source, such equipment must have a seasonal average yield (sCOPdhw) greater than or equal to 2.5 when electrically driven (i.e., when it uses electrical primary energy for its operation).

The most used equipment throughout the year in your home is the one in charge of heating water, since this is a service that we require throughout the year, more time in active than the air conditioning system. Therefore, it is essential that the DHW equipment is of the highest quality and efficiency possible.

Despite the overall significant improvement of these devices, they are not all the same.. Their differences are mainly based on the value of that average seasonal yield. For your home at MarPlus, we have exhaustively searched for the most efficient DHW equipment on the market. we could offer. That's why, we have selected the high-end equipment Daikin EKHLE-PCV3which has a COP of 4.23, far superior to most available equipment in the market, most of which are focused on meeting or minimally exceeding the value of 2.5 required by HE4.
This Daikin equipment is indeed high-end and high priced, but so are its features and that's why we've already included it in your new MarPlus home. Thanks to this performance, the selected team achieves a A+ energy rating, the maximum possible for this category of equipment.

Here you have access to the specification table of the Daikin EKHLE-PCV3. Indeed, in the table you can see that for a nominal power consumption of 0.43kW, i.e. 430W, it has a rated heating capacity of 1.82kW (1820W). Thus:

COP = Rated power obtained / Rated power consumption = 1.82kW/0.43kW = 4.23, as also indicated in the table.

In addition, the selected Daikin equipment has among other features:

  • A modern and compact design with a capacity of 200 liters.
  • Anti-legionella cycle.
  • Programmable operating capacity.

With this article, we have completed the information of the three active components that we have planned to install included in the price of your new home to obtain and enjoy maximum efficiency, comfort and well-being:

  1. The heat pump system by aerothermia for DHW described in this article.
  2. The air conditioning system, in the article: MOST modern and efficient air conditioning. The system chosen for MarPlus.
  3. The double-flow controlled mechanical ventilation system with heat recovery, in the article: Mechanical ventilation systems, what are they, their types, how they work and which one we have selected for MarPlus.

These three active systems complement the efficient passive envelope of your home. Do not forget that if you want to further improve your home with a renewable energy contribution, you can enjoy the OPTION+ PhotoVoltaic solar panels, see it from our blog article: PV solar panels, OPTION+ of MarPlus, how do they work, what production to expect?
