Starting point

Maria and her husband contacted us on the recommendation of their architect. They were building a modern 400m² house overlooking the Ría de Pontevedra, for themselves and their 4 children.

They were very clear that they wanted a modern and efficient air conditioning system, which would also fit in with the integral approach of the house.

After providing them with detailed information, they concluded that the system that best suited them was the heat pump.

As for the emission system, they decided that they wanted to install underfloor heating. The comfort of their family and the interior design of the house was a priority for them.

Customer concerns and preferences

In our first meeting, we agreed that a heat pump system was the best option. Our clients were indecisive about choosing a geothermal or an aerothermal heat pump.

After this first meeting, we decided to present them with a proposal for both options. To simplify their decision, we also provided them with an energy study that allowed comparing the annual energy costs with each of the systems.

After analysing both options, our customers found that in their case the most cost-effective choice was the aerothermal system.

The initial investment was much lower and due to the location of the house, the performance of the equipment was similar since the proximity to the sea guarantees high and stable minimum temperatures throughout the year.

Once they informed us about their decision, we raised the possibility of getting more out of the heat pump. As it can provide both heat and cold due to its reversible process, we advised them to install fan coils in certain areas of the house. Thus, they would have the option of providing cooling on the hottest days of the summer.

The idea suited them, as the house has large glazed areas facing west. These beautiful windows allow them to enjoy wonderful views of the Pontevedra estuary, but at the same time, bring large thermal loads into the house.

Our proposal

After several meetings, we designed an integral solution for Heating + Cooling + DHW with 2 air-to-water heat pumps.

Air-to-water heat pump system

Specifically, we proposed to install two air-source heat pumps model Enertres Brisa New 12M (2x12kW.) that work in parallel against a hot/cold inertia storage tank and a DHW storage tank.

Currently, there are no single-phase heat pump models that deliver 24 kW, which is the power needed to cover the energy demand of the house. For this reason, instead of one, we decided to install two units.

These two units operate in cascade. When the power demand is less than 12 kW, only one unit works. second unit only works if the demanded power is higher than 12 kW.

When designing the installation, a large inertia storage tank (750 litres) was considered. The objective was to improve the overall performance of the installation.

In addition, it would allow them to take better advantage of the discounted electricity tariff. They would be able to store energy during those hours when electricity is the cheapest (off-peak period) and release it when energy is the most expensive (peak period). It would also be valid in case they decide to integrate a photovoltaic installation into the future system.

For DHW production, we selected a storage tank specially designed for heat pump operation. We opted for a model with a capacity of 500 litres since such a large family had high daily water demands.

Emission systems: Underfloor heating and fan coil units

Underfloor heating was designed to cover only the heating needs of the house. The fan coils were designed to provide cooling in the summer and, if necessary, provide heating support.

Underfloor heating was designed to achieve a supply temperature of around 30-35ºC (86-95ºF), to obtain the best performance of the heat pump.

The fan coils were installed only in the most sun-exposed rooms, with the main objective of reducing the temperature during the hottest days.

The best energy is the one transmitted by our customers

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.

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.

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.

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!

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.
