The disclosure relates to a shower tray comprising a base element provided with a peripheral edge from where an inclined surface projects towards a drainage opening, and a surface for supporting the user formed by floor tiles, and strips which protrude from the inclined surface, wherein the upper faces of the strips form a horizontal base surface for the floor tiles, a groove is formed at least between two floor tiles for the evacuation of the water towards the inclined surface. The first ends of the floor tiles are secured on at least one transverse band or strip, and one swivelling end of the transverse band or strip includes a corner with a right-angled profile and adapted to slide on the longitudinal recess, when the floor tiles are withdrawn from their horizontal base surface.

A thermal recovery device for recovering waste heat from a sink having a bottom plate, the bottom plate having a top surface and a bottom surface, wherein the bottom plate being a thermal conductor, the thermal recovery device including: a tube including an inlet and an outlet, the tube thermally connected to the bottom surface, wherein thermal communication exists between the top surface and a fluid in the tube, a demand for the fluid causes the fluid to flow through the tube and heat transfer to the fluid which raises the temperature of the fluid prior to entering a heater and subsequently arriving at the top surface of the bottom plate of the sink from which the heat is transferred, reducing the heating load of the heater due to the demand of the fluid.

A water use management system may be installed in a setting that contains a primary infrastructure for water use to provide an alternate, modular infrastructure for water use. Fresh water used at various points of use, such as a shower or sink, may be modified by a point of use water conditioner. Water may be modified at the point of use based upon pre-configured routines or manual user selections. Treatments performed on the water may include quality treatments, such as modifying the pH or mineral content, and may also include experience treatments, such as the addition of scents, colors, carbonation, or health and beauty supplements. Additives used during treatment are provided in cartridges that may be inserted and removed from the water conditioner. Cartridges may self-identify when inserted, to aid in compatibility and usability determinations and recycling/recertification processes.

The present invention comprises a sanitary facility management system as well as a corresponding sanitary facility management method with at least one sanitary installation, which is coupled to a water supply and/or is included in a water circuit and on which at least one operating value of the at least one sanitary installation can be recorded, a sanitary facility control device connected to the at least one sanitary installation comprising at least one data transmitter and at least one signal receiver and a data processing and signal output system communicating with the sanitary facility control device via the at least one data transmitter and the at least one signal receiver, wherein the data processing and signal output system is a system learning by machine and/or a system comprising an artificial neuronal net and/or an expert system.

The present invention describes a water recirculation system intended for recycling of water or discarding of water not suitable to recycle, said water recirculation system (1) comprising a flow path for recirculation (50), at least one water treating unit (6), and a sensor unit (7) arranged for measurement of at least water quality, and wherein the sensor unit (7) is connected to a control unit which decides if water should be recycled or discarded in a point of separation (30) based on the measurement of the water quality, said water recirculation system (1) also comprises a first heating source (00), and wherein the water recirculation system (1) also comprises a second heating source (200).

The present inventive concept relates to a system (100) comprising: a water recirculating device comprising: a heating arrangement (112) arranged in a recirculating path (108); a mixing valve arrangement (122) in liquid communication with an external ON water path arrangement (114), said mixing valve arrangement (122) accepting as inputs hot and cold water from a hot and cold water source respectively, said mixing valve arrangement (122) being configured to form temperature regulated water (120) by combining said hot and cold water, said mixing valve arrangement (122) comprising a user input interface configured to control a proportion of said hot and cold water directed to said external water path arrangement (114); and a reference temperature determining arrangement (130) configured to determine a reference water temperature of said temperature regulated water (120); wherein said heating arrangement (112) is configured to adjust a water temperature of treated water towards said reference water temperature.

According to one embodiment, a wet-area device includes a main part and a first layer. The first layer is provided on an outer surface of the main part. The main part includes a main part unevenness at a side of the outer surface of the main part. The main part unevenness includes a plurality of main part recesses and a plurality of main part protrusions. The first layer includes a first unevenness at a side of an outer surface of the first layer. The first unevenness includes a plurality of first recesses and a plurality of first protrusions. The first unevenness is arranged along the main part unevenness. An average height of the main part unevenness is less than an average length of the main part unevenness.

A system of visual and non-visual marks for pipes and couplings which allows users to group the pipes and couplings by type, size, end configurations and composition with a series of symbols, including colors, shapes, swirls, patterns. The symbols are applied to the pipes and couplings by printing, etching, painting, applying stickers, and or molding. The non-visual mark utilize the magnetic and radio reflective nature of the marks to allow remote identification of the plumbing pipes and couplings after being buried.
