Starting point

Ana and Diego contacted us when they were building their new house. At the time they were considering installing a natural gas condensing boiler with solar thermal panels to cover their heating and DHW needs.

Additionally, they were exploring the idea of integrating an air conditioning system for cooling.

Regarding the emission system, they were clear that they wanted underfloor heating.

Customer doubts and preferences

In our first conversation, they expressed their doubts regarding the advantages of installing a heat pump. They already had several budgets for this system, but they did not understand why there was such a difference in price and what benefits a geothermal installation could bring them.

They also explained that for them it was a priority to always have an adequate temperature in their home, but not at the expense of high energy costs. They were willing to assume a higher initial investment if they could amortize it in the short or medium term.

Our proposal

From this meeting on, we designed an integral solution for Heating + Cooling + DHW + Pool heating.

Geothermal heat pump

Specifically, we proposed installing a geothermal heat pump by the Austrian manufacturer IDM, model TERRA 20SW TWIN HGL. This way, they would have heating in winter and cooling in summer provided by a single piece of equipment.

Loop circuit

We explained to them that having 3 vertical boreholes of 110m (361ft) each would allow taking advantage of the energy that accumulates in the subsoil and achieve greater savings, even with extreme weather conditions.

Radiant floor heating and cooling

We proposed the installation of an IDM geothermal heat pump model TERRA 20SW TWIN HGL. In addition, we designed the underfloor heating so that they could use it for both heating and cooling. We explained to them that contrary to what they had been told, with our system it was possible to turn underfloor heating into cooling. The heat pump incorporates a sophisticated climate control system that can determine the ideal supply temperature at any given moment. This way, the risk of condensation can be avoided at the time of cooling production.

Free passive cooling

In addition, as it is a geothermal heat pump, a large part of these cooling needs would be covered free of charge through passive cooling.

Free pool heating

Finally, we explained to them that this system would allow heating the pool completely free of charge in spring or summer when the heat pump is operating in cooling mode.

Remote control of the heat pump

We showed them the IDM app that allows controlling the operation of the heat pump through the mobile phone. With this application, they can decide at what temperature and when each room should be heated, even when they are not at home. Additionally, the installation’s operation can be viewed in graphs and statistics at any time.

The decision

After the second meeting, their vision of the geothermal heat pump changed completely. Aware of the benefits that this system would bring them, they assumed that a higher investment was fully justified.

By using Energanova’s solution, they were able to fulfil their desire to enjoy comfort without having to worry about the energy bill.

Operation of the installation and savings generated

After some weeks of work, in April 2016 we finished the installation.

In comparison to the gas boiler and air conditioning system that they initially intended to install, they have been able to save 1,800€ in one year with this system.

A step towards self-consumption

Ana and Diego are so happy with their heat pump system that they have decided to take a step towards self-consumption.

In July 2017, we incorporated a 3.12 kW photovoltaic self-consumption system into the house. This installation will allow them to save around 600€ more per year since it will produce much of the electricity needed by the heat pump for its operation, free of charge.

We were delighted with the installation. We wanted thermal emitters for our village house and everything went perfectly, they work very well. The installation was very simple and fast, fulfilling perfectly with what they offered us. They are very professional and attentive. We will work with them again.

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!

I am very satisfied with this company. They have advised and informed me throughout the project in a very professional manner, they are very good technically speaking, and you can tell they have a lot of experience. Aesthetically, they have taken care of every detail so that the installation was integrated into the house and the wiring was as concealed as possible. I had other more economical proposals at first, but in the end, they even got me a grant that covered a good part of the budget. In short, ENERGANOVA 100% recommended.

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!

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.

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.
