The wood-burning boiler that had been fulfilling its purpose up to now has remained in place and is now retiring, although it will continue to be operational in case it is needed at any time given that a problem, repair or maintenance of the unit may arise.

The self-consumption photovoltaic system is sized quite well to be able to cope with the house’s consumption plus the new consumption of the aerothermal energy; it also has a battery bank to ensure that consumption is covered at night; however, the batteries will have to be increased because at night, with the aerothermal energy working at full capacity, we fall short, but this was already known when the sizing was done. However, as it is an easily expandable item, it was preferred to start with something almost symbolic, so that when real and reliable data was available, the relevant modules would be implemented to cover the entire consumption of the installation. Photovoltaics will provide practically 100% of the energy consumed by the house, having periods in which there will be a surplus of energy because the self-consumption photovoltaic solar system will allow this to happen, due to its oversized size, which we can take advantage of for the solar wallet, and thus have a surplus for the months in which the sun is more difficult to see.
