Bela Fisterra Hotel, located in the heart of Costa da Morte, is one of the few hotels in Spain that has a geothermal system to provide air conditioning and hot water. This hotel, closely related to the sea, is also perfectly integrated with nature and has been designed with an eco-sustainable and environmentally conscious concept.

Starting point

Bela Fisterra is a literary hotel closely related to the sea. Each of the rooms is inspired and dedicated to great works and authors of sea-themed literature.

Located in a natural environment and fully integrated into nature, the hotel was conceived from the beginning under a concept of sustainability. Its commitment to nature goes beyond being located in one of the most natural areas of Galicia. The owners were looking for total integration with the environment.

Therefore, they were clear from the beginning that they wanted to use a renewable system for air conditioning and DHW. Geothermal energy met all the requirements they were looking for: respect for the environment and energy savings by making use of a renewable system.

That is the reason why our proposal took this direction from the very beginning.

Our proposal

The heating and cooling systems we proposed took into account the great needs of a hotel. We were looking for systems that would provide total comfort while consuming less energy. In addition, when presenting our proposal, we were looking for an efficient system for the production of DHW since it is one of the major sources of energy consumption in a hotel.

Aerothermal heat pump

Our proposal was a geothermal heat pump by the manufacturer iDM-Enertres, model Terra Twin 35 (35 kW).This equipment has a reversible cold/heat process to meet both heating and cooling demands of the hotel.

This heat pump, in addition to having one of the highest efficiencies on the market, has HGL technology for the production of DHW. This technology, patented by the Austrian manufacturer iDM, guarantees the production of DHW with minimum consumption. Therefore, it seemed to us the ideal system for this hotel, due to the high demand for DHW.

Heating/cooling buffer tank and instantaneous DHW production

In addition, we installed an Enertres 300-litres storage tank for domestic hot water (DHW), model DPSA.

We proposed to install a 1.500-litres buffer tank with an instantaneous DHW production system of 70litres/min, considering the high demand of the hotel.

With this instantaneous DHW production system we can guarantee the hygienic production of hot water. In addition, as there is no storage, we avoid the weekly anti-legionella treatment required for this type of establishment. This means greater safety and savingssince it is not necessary to reach high temperatures to guarantee DHW production.

As for the hotel’s heating and cooling system, we proposed the installation of an inertia storage tank with 4 flow diverter valves. This way, we facilitate stratification at all times, regardless of whether the mode of operation is summer or winter.

Geothermal loop circuit

Being close to the sea, this was a complex area for drilling, as the ground is soft and could easily collapse. For this reason, the wells had to be drilled using special drilling machines with double-head technology, which allowed simultaneous drilling and casing.

To dimension the loop circuit we carried out a simulation. This way, the subsoil’s exact thermal extraction power could be determined. This test is important in this kind of installations with high energy needs.

The tests carried out determined an extraction capacity of 62W per linear meter of the borehole.
Consequently, three 140m (459ft) deep boreholes were drilled.

Emission system

Cooling and heating are provided by high-efficiency ducted fan coils with DC inverter fans and LEC technology from Daikin.

In the rooms and common areas, linear diffusers and carefully designed ventilation grilles were installed, in keeping with the elegant and minimalist style of the entire hotel.

In addition, towel radiators were installed in the bathrooms, powered at high temperatures by the Hygienik accumulator and HGL technology.

Operation of the installation

The installation was carried out between March and April 2018. The hotel opened in July 2018.

Since then, this 3-star hotel has already welcomed numerous guests who have enjoyed a natural environment in a building where comfort, design, and care for the environment have been successfully combined.

After wanting to invest in photovoltaic technology, I started to search the Internet for companies that could give me an estimated cost, until I found Energanova. From the start, Javier assisted me as a customer wants to be assisted, with patience and respect, because not everybody knows what a solar panel, an inverter, etc… is. Energanova is worth it; they are trustworthy. Thank you.

The company works well. They offer different alternatives after studying your problem, answering and clarifying all the doubts you may have. They provide a fast and efficient response. They are good professionals that have adequate documentation and information about the operation of the facility. They take care of all the administrative procedures, including subsidies. We are very satisfied!

Pincheiro AT, our apartment complex in A Pobra do Caramiñal, bets on renewable energies, especially geothermal and photovoltaic technology. We can assure you that Energanova has greatly fulfilled all our expectations. We can confirm, and this is difficult, the honesty of this company since what was budgeted at the beginning corresponds reliably to what we have been invoiced. We can only say on the part of Pincheiro AT that we feel in good hands both for what has been done on-site and in terms of the timely follow-up being performed.

Excellent company. You contact them and they quickly go to your home to decide what its ideal installation could be, solving any questions you may have. They have better prices compared to other renewable energy companies. Fast and well-executed installation. In my case, I asked for the Inega subsidy, and as an authorized installation company they take care of everything, being the first to get it so that you do not run out of it. If I had to do any other installation, I would contact them without hesitation.

Great company and quick installation. We renewed our old geothermal machine for one of the best in the market. The savings are impressive, and the electricity bill has fallen radically, but for me, the best thing is the after-sales service. You can obtain assistance at any time, both by telephone and face-to-face. Great job!
