Housing type in San Sebastián de los Reyes

A municipality with very different housing types

San Sebastián de los Reyes combines an old town with blocks of flats from different eras and residential areas of single-family homes on the outskirts, which calls for very different solutions depending on the building and neighbourhood. The older flats in the centre often still have electrical systems that no longer meet today's needs for climate control, appliances and lighting. Single-family homes, in turn, have more scope for larger-scale installations such as air-source heat pumps or underfloor heating. In both cases, the technical starting point shapes much of the project.

Climate control

Climate control tailored to the type of home

In the municipality's flats, ducted air conditioning with zoning brings a real gain in comfort without major building work, distributing air only to the rooms actually in use at any given time. In single-family homes with a garden, an air-source heat pump combined with underfloor heating and cooling offers a notable jump in efficiency compared with conventional gas or electric systems.

In both cases, we take care to keep the installation discreet and respectful of the home's existing design, with outdoor units well positioned and ductwork built into the false ceiling wherever possible.

Electrical

Power capacity and charging suited to the type of home

In single-family homes with their own garage, we install the electric vehicle charging point in accordance with ITC-BT-52, with a dedicated circuit run from the main consumer unit. In blocks of flats with a communal garage, the process involves a collective project that the residents' association can expand over time. When a home renovation includes induction cooking or a high-power oven, we also check whether the electrical certificate needs updating.

LED lighting and home automation round off the project with lower consumption and lighting scenes that adapt to how each room is actually used, from the living room to the garden.

A common case in San Sebastián de los Reyes

In San Sebastián de los Reyes it's common for older flats to have an electrical system that falls short as soon as air conditioning is added to what's already there: a washing machine, oven and several kitchen appliances. The clearest symptom is that the trip switch goes right in the middle of summer, exactly when the climate control is needed most. Updating the contracted power along with the consumer unit fixes the problem at its root.

Electrical certificate for renovations in older single-family homes

Cause: When renovating single-family homes of some age, circuits are extended or equipment changed without updating the electrical certificate with the distribution company.
Effect: The installation can end up without the residual current protection required for the new circuits, causing problems when legalising the renovation later.
Prevention: Arrange an updated electrical certificate as soon as any circuit is extended or modified, not at the end of the renovation.
ANNA's diagnosis: ANNA manages the update of the electrical certificate and the certification of the renovated installation in line with current regulations.
