    The water saving system in the hot water installations of the buildings consists of applying to the hot water pipes of the buildings a complementary heating system consisting of: a) an external electric heater that is placed around the hot water inlet duct in an area close to the related tap, b) a bypass through a small conduit between the thermos and the various taps or water outlets and a pump driven by an electric motor, for a period of time controlled by a time delay circuit or ) a flexible teflon duct placed inside the existing or existing hot water pipes, joining the external end that carries the recirculation pump, to the water inlet pipe of the thermos. The external electric heater is supplied with a low voltage current through a transformer. (Machine-translation by Google Translate, not legally binding)

    The hot water pipes must be made of a thermoplastic material, Teflon or similar, of a temperature high enough so that melting or weakening of their joints or joints does not occur. A check valve prevents the circulation of water through the bypass when the pump does not operate.
    Bypass can be made between the water inlet of the heater and a point near the outlets or the farthest faucet of hot water. You can use internally coated metal pipes with a layer of thermal insulation, Teflon or similar material
    If the pump fails, the installation continues to operate as it currently does.
    The pumps must be conveniently insulated and use high temperature thermoplastic material. The power supply can be isolated and by means of one or more transformers in series, which in turn reduce the voltage to safety values. In gas heaters it may be necessary to turn this on before opening the tap since its operation is different and does not store hot water.
    Operation: When entering a sink and turning on the light, the water pump starts for about 30 or 40 seconds, or depending on the characteristics of the building, enough time for the hot water of the heater to recirculate between it and the tap or faucets From that moment, and without having wasted any water, you can open the tap and the water will come out hot. Due to the type of heat insulating pipe used, the water will be less cold and take less time to heat. The system can also be put into operation by pressing a button on the heater, when opening the washbasin door, by means of a photoelectric cell, etc.
    Advantages: It is very simple, economical and due to the large number of homes or buildings in which it can be applied, it allows a great saving of water and a great benefit for the environment.
    BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 shows a schematic, side and partial view of an installation with the system of the invention. Figures 2 to 4 show schematic, side and partial views of some installations, variants of the system of the invention. Figure 5 shows a schematic and partial view of an installation
    partially sectioned, variant of the system of the invention
    MORE DETAILED DESCRIPTION OF THE INVENTION
    The invention, figure 1, shows an electric water heater (1), the cold water pipe (3), the hot water pipe (4), the electrical resistance (15) which surrounds the pipe and is fed through of the transformer (14) that reduces the voltage to a safe value of between approximately 9 and 24 volts and which is fed by the mains electricity when the switch (10) is pressed, which is kept activated for about forty seconds by means of the circuit Electric or electronic (11) time delay.
    Figure 2 shows an electric water heater (1), the cold water pipe (3), the hot water pipe (4), the electrical resistance (15) which partially surrounds the pipe, for which it carries an opening side and is fed through the transformer (14) that reduces the voltage to a safe value of between approximately 9 and 24 volts, and which is fed by the mains electricity when the switch (10) is pressed, which is maintained activated for about forty seconds using the electrical or electronic time delay circuit (11). To increase the insulation, two or more transformers can be placed in series. It is similar to that of figure 1, but due to the lateral opening of the heater or electric heater, it can be adapted to current systems, or already in operation, without having to carry out disassembly.
    Figure 3 shows an electric water heater (1), the cold water pipe (3), the main hot water pipe (4), the bypass pipe (5) placed between the hot water tank (6) and the tap (2), the electric motor (7) that drives the turbine
    (8) and is fed by the electric current point (9) and the switch (10) which is kept activated for about forty seconds by means of the electrical or electronic time delay circuit (11).
    Figure 4 shows a water heater (1), the main hot water pipe (4), the bypass pipe (5) disposed between the cold water inlet pipe to the heater (12) and a distant distribution point ( 14), the electric motor (7) that drives the turbine (8) and is powered by the electric current point (9) and the switch
    (10) which is activated for about forty seconds by means of the electrical or electronic time delay circuit (11). Add an optional check valve (13) to prevent the circulation or withdrawal of cold water when the pump is off.
    Figure 5 shows the heater (1), the hot water pipe (4), the Teflon internal duct (5a), the electric motor (7), the turbine (8) and the cold water inlet pipe (12 ). of the heater. The end of the duct (5a) opposite the pump is free and sucks water from inside the duct (4) at a point distant from the heater.
    All elements in contact with the installation, transformer, heater or resistance, etc. they must be conveniently insulated electrically.
