Energy Service
For More Information:
Geothermal Energy can provide up to 100% of a household heating and hot water daily needs, as well as to building type with a wide array of energy needs, whatever the external conditions are (even with freezing temperatures).
Geothermal Energy relies on the earth’s ability to store huge amounts of heat under its surface. An inexhaustible energy source, available all year round for 24 hour each day. It is not influenced by weather conditions.
It can provide also cooling in summer, all of this with the same single HVAC system, able to work with radiant floor, fan-coils, or almost any heating or air conditioning system.
Earth’s crust has steady areas with low heat flux and unstable areas with an elevated heat flux. Both areas define the two geothermal energy types.
The main applications of geothermal energy are as follows:
- Heating in houses, buildings and industrial buildings
- HVAC refrigeration centres, cooling/freezing storage, etc
- Production of Sanitary Hot Water (ACS)
- Air conditioning of swimming pools
- Aquaculture
- Cattle raising
Aerothermia Energy Services

For More Information:
Aerotermia is a low-investment renewable energy source that is used both to produce sanitary hot water and air conditioning of homes or enclosed spaces. Because of its simplicity and low cost, it is the most viable option in many projects.
Aerothermal energy (or aerothermy) is a renewable source able to extract the energy contained in the air that surrounds us, to use it for different purposes.
The heat pump is a thermal machine capable of pumping heat from a cold source to a hot one. In the case of aerothermal heat pumps, they extract heat from the natural environment (air) through the evaporator and transfer it to the interior of a building or to industrial processes through the condenser. If they are reversible, heat can be transferred from the interior of the building to the external environment.
Nowadays, aerothermy can be used to produce domestic hot water and also for heating and air conditioning of homes or enclosed spaces.
The ratio between free energy and payment energy varies according to the outside temperature. The colder it is, the harder it is to extract heat and the more heat it makes, the harder it is to extract cold.
For the purposes of accounting for the renewable energy quota established by Directive 2009/28/EC of the European Parliament, the energy captured by heat pumps will be taken into account provided that the final energy production significantly exceeds the input of primary energy needed to drive the heat pump, that is, only a part can be considered renewable.
It is possible to hybridize these systems integrating them as support in geothermal systems, in such a way that they optimize both the necessary investment and the operation of the system.
Biomass Energy Services
Energy Service
For More Information:
Biomass consists on organic matter, of vegetable or animal origin, and the materials that come from its natural or artificial transformation. A very broad concept that includes everything from waste from forestry, agriculture and livestock to the organic fraction of domestic and industrial waste, through the by-products of agro-food industries and wood processing.
The main fuels obtained from biomass are firewood, wood chips, pellets, olive stones and fruit peels.
The thermal applications of the biomass can be carried out mainly through boilers, stoves or chimneys. The boilers are the only equipment capable of providing heating and sanitary hot water at the same time, while the stoves and fireplaces allow to heat the room in which they are located. The boilers can be installed both in single-family homes and in neighboring communities of any size, since boilers can be found from 20 kW to more than 1 MW (and much larger sizes for heat networks and industrial or power generation applications).
An especially interesting option is the heat networks, which due to their greater energy efficiency and the use of economies of scale, allow reaching a greater number of users.
Photovoltaic Energy Services
Energy Service
For More Information:
Photovoltaic solar systems take advantage of solar radiation by transforming it directly into electrical energy through the photovoltaic effect, which consists in the emission of electrons by a material when it is illuminated with electromagnetic radiation (in this case, solar radiation).
There are different photovoltaic technologies (fixed, solar tracking to an axis and solar tracking to two axes) but most are based on silicon.
Photovoltaic solar systems can basically be of two types: isolated installations, mainly oriented to pumping applications, signaling, communications and rural electrification, and grid-connected installations, aimed at the sale of electricity and self-consumption.
The possibilities of application of PV energy are immense and range from the most simple applications such as calculators and solar watches, to the more complex ones such as large power generation plants or power systems for artificial satellites.
Currently it is possible to integrate photovoltaic energy in renewable systems such as geothermal energy, thanks to the low energy demand of this technology, with a very small investment. This way, 100% renewable systems with no environmental impact are possible.
