Electricity systems

The current criteria for the design, installation and testing of electricity systems are checked by strict regulations and guarantees a very high level of performance.

Regulation CEI 64-8/3 "electrical installations for users with a rated voltage not exceeding 1000 volts in alternating current and 1500 volts in direct current", effective since 1 September 2011 in its newest version for newly installated installations, introduces important new functions in areas of performance, energy saving and living comfort. This regulation also stipulates that the number of components in the new installation must be based on the surface of the dwelling and must be divided into three different performance levels :

  • Level 1 Basic : for those who only choose the most important, the system is equipped with the minimum equipment
  • Level 2 Standard : for those who choose a higher level of safety, usability and comfort
  • Level 3 Home automation : intended for the user who chooses a system that meets the highest standards

The installer can certify the quality and performance level of the system, which leads to the increase in value of the building.

A number of the legal provisions are described below:

  • Depending on the surface area of the property, it is necessary to provide a capacity of at least 3 Kw for residential units up to 75 square metres ; for larger surfaces it is necessary to provide at least 6 Kw of power with the obligation of a signed project by a qualified technician with contractual powers for more than 6 Kw;
  • The junction box is mandatory and must be equipped with a 25 amp main switch for a capacity of 3 Kw, or 32 amp for 6 Kw, depending on the capacity of the system. In order to enable future expansions, 15% more modules must always be available than the installed modules, and at least 2 free modules;
  • The cables must be removable and the colors of the non-conductors have been determined by the standard CEI-UNEL 00722;
  • It's mandatory to distribute the terminal circuit of the dwelling over at least two different switches;
  • The cable connections must be made with the appropriate connections in the cable box;
  • The on and off button on the connection cables is maximally permitted between two successive switches;
  • Each space has a minimum capacity allocation, as indicated the the New Annex A of the Legislation CEI 64-8/3.

Hydraulic systems

The distribution of hot and cold water takes place through a hydraulic system that conducts water through pipes. The hydraulic system mainly has three functionsi:

  • The supply of hot and cold water, both through the waterworks or water tank
  • The water distribution within the hydraulic system
  • Discharge of dirty water in the sewerage or collection tank

The most important parts of a hydraulic system are:

  • The junction box: when the junction box is placed outside the building, it's necessary to place a general shut-off valve in the building, in an easily accessible position.
  • The internal hydraulic system: from the junction box the water is distributed through pipes from the internal system to the user devices. The pipes may be installed in two ways : visible or inside the walls so that they aren't visible. When installing an internal system with the underground pipes, it's extremely important to comply with the safety regulations. The UNI 9182 legislation applies to this.
  • User devices
  • Drainage: the drainage systems serve to allow the water from washbasins, toilets, showers, bathtubs, sinks etc. to leave the building. A distinction is made between "black" water (toilets), "grey" water (sinks, washing machines, bidet etc.) and "grease" water (kitchen).

Gas installations

Methane is the most commonly used fuel for heating our home, for cooking and for hot water.  Off all fossil fuels, methane is the least polluting, but it's also highly flammable and generates carbon monoxide, a toxic element for humans. It's therefore extremely important to have safe gas installations that comply with applicable regulations and are installed by qualified companies and employees who, after installation and testing, will provide a declaration of confirmity of the installation.

The most important parts of a gas installation are:

  • The gas meter: when the gas meter is placed outside the building, it's necessary to place a general shut-off valve in the building, in an easily accessible position.
  • The internal gas connection: From the gas meter the methane is distributed through pipes. The pipes may be installed in two ways : visible or inside the walls so that they aren't visible. The UNI CIG 7129 legislation applies to this.
  • User devices

Thermo-hydraulic systems

Thermo-hydraulic heating is a system that uses hot water as a heat transfer fluid.

The heating system consists of two parts:

  • the heat production system
  • the heat transfer system
  • Heat generators: heat production systems are classified with the fuel type as a base (coal, gas oil, gas, wood etc.) or the energy source (geothermal, solar, electric etc.) to heat air, water or steam which are then transferred to the appropriate destination points. The heating system can also be connected to the domestic water production plant. The most common systems are : boilers, heat pumps and fireplaces.
  • Final conduction: After the heat production, the warmth in the house must be spread by means of water-air heat exchange units. The heat conduction can take place in three ways : through radiators, fan convectors and radiating panels.

The choice of a thermo-hydraulic system is more complicated than you think, therefore we will bring the client in contact with an installer who can advise you in the choice and with whom you can discuss your personal needs.

The most common thermo-hydraulic system in our country produces heat through a generator, almost always a boiler, and distributes water via incoming and outgoing pipes. The water in this case is the heat transfer fluid.
