Rodrigo is the owner of a villa located in Ibiza. Diesel boilers and DHW accumulators provided the house with heating and domestic hot water, air conditioners provided cooling, and a heat pump provided pool heating. Underfloor heating and radiant wall heating were selected for the house’s emission system.
As a result of its 3.000m² (32.292ft2) heated surface and a large outdoor swimming pool, this house has a very high thermal demand.
The owners of the villa wanted to simplify the system and replace it with an integral solution. As a result of this high demand, they searched for an alternative that would be moreenvironmentally friendly and reduce consumption.
In their search for an integral and renewable system, they contacted us. As they explained, they wanted a single solution to meet their heating, cooling, hot water, and pool heating requirements.
Our recommendation was to install an aerothermal or geothermal heat pump system by the Austrian manufacturer iDM, which combines both the cooling system control and photovoltaic self-consumption, allowing the client to take advantage of the electrical surpluses for thermal storage.
As far as photovoltaic production is concerned, we offer 2 different proposals, being the first one self-consumption with storage using lithium batteries and the second one without them.
Our team of engineers is specialized in photovoltaic self-consumption systems with heat pump integration. We prepared a complete energy study of the installation. In this report, we detailed what the initial investment would be with each of the proposals. In addition, we indicated estimated consumption and savings.
With all this information, the client could analyse in detail the pros and cons of each of the options. After evaluating the different proposals, they finally opted for the geothermal option combined with photovoltaic self-consumption.
This option would allow them to reduce by 75% the energy expenditure needed to cover the demand for heating, cooling, pool heating, and DHW.
By replacing the diesel boiler with a geothermal heat pump, the consumption of fossil fuels would be eliminated and all the consumption of the house would be exclusively electric. This would allow a higher yield to be obtained from the self-consumption photovoltaic installation since the photovoltaic panels would produce around 25%-30% of the electricity needed for the entire house.
A great advantage of the solution chosen by the client is that it allows the simultaneous production of heat and cold with the same consumption. In other words, one of the two demands is covered free of charge. Thus, for example, while cooling the house we can heat the swimming pool for free. This way, we optimize the use of energy, with the consequent savings and benefits for the environment.
Finally, the installation consisted of the following elements:
12 boreholes are drilled with a length of 125m (410ft) each, in which 32mm (1,25”) double “U” probes are inserted and injected with high conductivity geothermal mortar.
We chose the geothermal heat pump by the Austrian manufacturer iDM model Terra MAX 110, which delivers a power of 149kW in heating mode and 132kW in cooling mode.
A 1,000-litres buffer tank with a 50l/min module is installed for the production of domestic hot water (DHW).
For the heating/cooling inertia we installed 2 Enertres accumulators, model DPI -1000F of 1,000-litres.
It was decided to install 1.000-litres accumulators for the thermal use of photovoltaic surpluses. The Navigator 2.0 control of the heat pump, which integrates the photovoltaic function, makes it possible to use the photovoltaic surpluses to accumulate energy in the buffer tank. In winter, it is stored as hot water for heating, while in summer it is stored as cold water for cooling.
This energy is stored and will be available for free for later use, since sooner or later there will be a demand.
Using an external hydraulic cooling kit, we can generate both cold and heat simultaneously, one of them free of charge.
To control the installation, a humidity and temperature sensor is installed in a representative area of the house. The iDM heat pump integrates a control system, called Navigator Pro, which allows the supply temperature to be adjusted based on the information provided by the sensor. In doing so, it ensures a comfortable temperature at home at a minimum energy cost.
The installation can also be controlled remotely and free of charge using the manufacturer’s app.
A 10kW peak power photovoltaic kit is installed (25 panels of 400W Canadian Solar) with a 10kW Fronius Symo inverter that is integrated into the heat pump regulation.
With a photovoltaic production capacity of about 16.000kWh per year and a self-consumption capacity of 98%, it is only possible to consume 2% of what we produce because there is not enough consumption in our home. This is what is known as photovoltaic surplus, which we will inject into the grid and for which the electricity company will compensate us at a rate of approx. 0.05€/kWh.
I have carried out with ENERGANOVA a geothermal installation with photovoltaic technology and we are very satisfied with both the execution and the consumption achieved. mos. Especially, since electricity is currently skyrocketing and we only pay 20€ per month. 100% recommended company in all aspects.
Energanova is a serious company, which at all times explained and helped us in everything related to the photovoltaic installation, which is perfect. They have looked for specific solutions for a much reduced space. 100% recommended.
They are great professionals, punctual, scrupulous with the work, and very serious. I will hire them again for another project. Thank you.
They are good professionals and very agile. I have installed photovoltaic panels with them and I am delighted.
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!
I am going to tell my experience with this renewable energy company. First of all, I must say that I have always considered myself a ‘difficult’ person as a customer, who demands seriousness and professionalism in all the services I hire, especially for my house. Well, I have to say that on this occasion my satisfaction is maximum and I want to congratulate the whole Energanova team for its professionalism through this review. Nowadays it is not easy to find companies that do things well, and I must tell you that this company does them very well.
I have been advised and informed throughout the project in a very professional manner, as well as helped in the management of the subsidies. They provide customized attention and follow-up after the installation to get the most out of it. I think this is the way to switch to renewable energies, by overcoming the stress and insecurities that we may have. ENERGANOVA 100% recommended!!!!

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.
Very professional!
We have had an excellent experience with Energanova. They have complied with the deadlines, the staff was very professional, and the work was clean and very fast for both geothermal energy and photovoltaic panels. We applied for the grants of the Xunta de Galicia and they were in charge of managing it completely. We are very pleased with our choice, both for the treatment and the result of the installation.
We have had at home an air-source heat pump and a photovoltaic system installed by the company Energanova for a few months. As regards savings, at the moment our electricity bill has decreased by 70% and we no longer have to order diesel! If someone is encouraged to install renewable systems, I recommend that they look for a professional company. We are very happy with our choice.
I have worked with Energanova in the rehabilitation of a house and I am very happy with my choice. It is a close and professional company. They have a great team that explains in detail to the architect, technical architect, and builder as well as to the property the benefits of everything before, during, and after the work. Highly recommended!
Good experience, good work, meeting deadlines, and everything running smoothly. We are very happy and now even more with the rise of light prices! They have also facilitated the cumbersome process of applying to Xunta de Galicia’s subsidies. I encourage people to choose this company!!! Good choice.
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.
We contacted Energanova because we wanted to change our old gas boiler for a more efficient and environmentally-friendly system. It is noticeable that they are specialists in this type of work since they have proven to be very professional at all times.
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.
Finally, a company that gave me what it offered. It is difficult, but if in the end you find a company like this with great professionals, the result is very satisfactory.
I installed the air conditioning of my house with a geothermal heat pump (iDM), underfloor heating, and photovoltaic panels with Energanova. We are very satisfied with the result. As a company they are very serious and professional, they advised me at all times. With this installation, the house is very comfortable and the consumption is reduced. It is a 100% recommended company.
Quick response and excellent professionals, I recommend them with no doubt.
I can say that they are a company in which at all times both the technical advice and professional treatment were according to my needs. If you are thinking about installing a heating/air conditioning system, do not hesitate to consider them as an option, because they are undoubtedly a solvent and serious company, which in these times is often difficult to find. Thank you Energanova!
Great company and quick installation. We renewed our old geothermal machine for one of the best in the market.
