- - pumping means configured to pump gray water through the supply line from the bathtub or similar shower tray to the top of the column
- - sensor means linked to the pumping means provided to detect a pressure value, such that in the event that a value lower than a predetermined detected pressure value is detected inside the interior chamber, the sensor means send a signal) to the pumping means to interrupt the supply of gray water through the supply line.
- an energy-saving system is obtained that is easy to install since it does not require, for example, construction work, without implying a greater height of the shower tray, bathtub or similar.
- the arrangement of the sensor means such as a positive pressure sensor, allows the operation of the system to be interrupted in the event that there is no minimum pressure inside the flat heat exchanger, that is, the interior chamber) to avoid having gray water. residual waste on the exterior wall in case there is a risk of gray water returning to the drinking water circuit due to depression in the network.
- the diffuser beds comprise two branches that extend from the gray water supply line, each located on an opposite side of the column, which are provided with at least one gray water outlet hole.
- the vertical column includes guiding means configured to guide the gray water along the surface of each of the facing faces.
- said guiding means consist of at least one fin that protrudes transversely with respect to the faces and extends along the entire length of the vertical column.
- system may include a protective cover that covers the length of the vertical column, so that the system is hidden and protected from dirt or external agents.
- the vertical column can be made of stainless steel.
- the heat recovery system described represents, therefore, an innovative structure with structural and constitutive characteristics unknown until now for the purpose for which it is intended, reasons that, together with its practical usefulness, provide it with sufficient foundation to obtain the privilege of exclusivity that I know requests.

- Figure 1 shows a shower installation (1) that includes a heat recovery system, which includes a heat exchanger that acts between the waters. gray water from the shower and the water to be supplied, to transfer the heat provided by the gray water to the water to be supplied.
- a heat recovery system which includes a heat exchanger that acts between the waters. gray water from the shower and the water to be supplied, to transfer the heat provided by the gray water to the water to be supplied.
- recovery system can also be used to treat water from two or more showers.
- this heat exchanger comprises a vertical column (2) with a rectangular cross section of little width, made of stainless steel, defined by flat faces or walls (20, 21) facing each other, defining an interior chamber ( 22) hollow (as schematically represented in figure 5) provided with an inlet (3) of water to be supplied and an outlet linked to an outlet point, in this case, linked to conventional taps ( 4).
- the system comprises a gray water supply line (5) that runs outside the vertical column intended to collect the gray water from the shower tray (1) and lead it to the upper part of the vertical column (2) so that it can be The heat exchange is carried out between the gray water and the sanitary water to come out through the tap (4).
- Water diffusion means linked to the gray water supply line (5) are also provided.
- the diffuser means being located in such a way that they provide a flow of gray water that falls by gravity on two opposite sides (vertical surfaces) of the vertical column. Mention that the gray water leaves the interior chamber (22) through an outlet. (23) located in a lower area of the vertical column (2) and are directed to a drain (11) located in the shower tray (1).
- these diffusion means comprise two branches (6, 7) that extend from the gray water supply line, each located on an opposite side of the vertical column (2).
- Each of the branches (6, 7) is provided with a plurality of holes (8) for the exit of gray water from the gray water supply line (5).
- a conventional pump 9 is provided (so it will not be explained in greater detail).
- a pressure switch 10 (sensor means) linked to the pump intended to detect a pressure value, such that in the event that a value lower than a predetermined pressure value detected, the sensor means send a signal to the conventional pump (9) to interrupt the flow of gray water through the gray water supply line (5).
- a protective cover (12) is provided, made up of a "U"-shaped profile, which covers the entire length of the vertical column (2), so that the system is hidden and protected. from dirt or external agents.
- the vertical column (2) includes guiding means configured to guide the gray water along the surface of each one. of the facing faces, which consist of at least one allele (24) that protrudes from one end transversely with respect to the faces and extends along the entire length of the vertical column (2), while at the end opposite a projection is provided (25)>
- This system described can also be part of a set that includes a vertical tank-heater attached to the exchanger, as can be seen in Figures 4 and 6.
- This tank-heater (13) can be powered by photovoltaic solar energy, with the grid general electric or a combination of both.
- the water heated by the vertical column (2) (which leaves at 30°C) can be sent to the heating tank (13) through a pipe (14) to subsequently provide hot water to the tap (for example, at a temperature of 60°C) through a pipe (15) or be sent directly to the tap (4) through a pipe (16) to subsequently mix with the hot water. (for example, 60°C) coming from the tank-heater to supply a flow at a temperature of 37°C,
- Figure 7 shows an alternative embodiment of the system where the same elements have the same numerical references, being in this particular case applicable to provide hot water to two taps (4, 4') located at different points or locations in space.
