  • the system comprises a water cylinder controller ( 100 ), a communication antenna ( 200 ) allowing it to be connected to the Internet, preferably by Wi-Fi, and two thermocouple cables ( 300 ).
  • the water cylinder controller ( 100 ) is arranged on a housing with a front panel on which elements allowing the system to be managed are arranged, wherein the front panel incorporates a mode button ( 1 ) allowing the operating mode to be changed; an operating indicator ( 2 ) showing the current operating mode and the status of the load switch; a boost button ( 3 ) enabling the reinforcing load; a reset button ( 4 ) restoring the controller if required; a communication indicator ( 5 ) showing connectivity status; a configuration button ( 6 ) allowing communications to be configured using the connection passwords; a light sensor ( 7 ) measuring the intensity of ambient light; a temperature sensor ( 8 ) measuring ambient temperature; a fuse for base load ( 9 ) protecting the base circuit against overloads; a fuse for reinforcing load ( 10 ) protecting the reinforcing circuit against overloads; a main switch ( 11 ) insulating loads in off position and allowing the controller ( 100 ) to control loads in on position; and a communication antenna connector ( 12 ).
  • the system comprises two thermocouple cables ( 300 ), wherein the end of a first thermocouple cable ( 300 ) is arranged at the cold water inlet of the hot water cylinder and the end of the second thermocouple cable ( 300 ) is arranged at the hot water outlet ( 300 ) and wherein the free ends of both thermocouple cables ( 300 ) are routed and connected to the controller ( 100 ); and an antenna ( 200 ) coupled to the communication antenna connector ( 12 ) for the connection of the controller ( 100 ) with another server or with the cloud, where the information is processed.
  • the communications allow the connection of the system with another server or with the cloud, where the information is processed by means of the collected data on the user's use and electricity tariffs and by means of an algorithm modelling the user's behaviour and the temperature of the water cylinder.
  • the mode button ( 1 ) works according to the following modalities of hot water controller:
  • thermocouple cables ( 300 ) Temperature is measured by means of the thermocouple cables ( 300 ).
  • a thermocouple cable is a temperature sensor composed of two different metals, joined at an end, that is sensitive to temperature changes.
  • thermocouples of different types those most commonly utilised for industrial use are the type K and J thermocouple. As indicated, they are models composed of a positive and negative conductor generating a MV signal, which will be converted by controlling equipment like the controller ( 100 ) of the invention.
  • thermocouple cables ( 300 ) are installed by arranging a cable both at the cold water inlet into the hot water cylinder and the hot water outlet. This is preferably effected with Kapton heat-resistant tape. The opposite end of the cables ( 300 ) is marked before routing them to the controller ( 100 ) to ensure their subsequent correct installation in their positions, and the thermocouple cables ( 300 ) are run to the controller box ( 100 ), i.e., the end of a first thermocouple cable ( 300 ) is arranged at the cold water inlet of the hot water cylinder and the end of the second thermocouple cable ( 300 ) is arranged at the hot water outlet ( 300 ) and the free ends of both thermocouple cables ( 300 ) are routed and connected to the controller ( 100 ).
  • thermocouple cables ( 300 ) are connected to the terminal blocks in the rear part of the front cover of the controller ( 100 ), taking into account the labels for the cold inlet and the hot outlet and the positive and negative signs.
  • negative poles ( ⁇ ) will be labelled in white and positive poles (+) can be of any other colour.
  • the system can measure the inlet and outlet temperature of cylinder's water in addition to the electrical power. This makes opening the water circuit for installation unnecessary, which can be effected by simply coupling devices to the surface of the cylinder tubes.
  • a suitable algorithm can estimate the total energy stored in the cylinder.
  • the obtained measured data are sent either to a central server or to the cloud where they are stored together with data on electricity tariffs, data from the user's history, connection time, etc., and are processed by means of an algorithm allowing the stored energy, times when hot water is used, etc., to be estimated, the user behaviour to be predicted and the energy consumption of the device to be optimised.
  • the system measures the temperature of hot water tubes (THot) and cold-water tubes (TCold) as well as ambient temperature (TAmbient) (see FIG. 4 ).
  • the system also records the heating power fed into the hot water cylinder, and whether the power is applied to the heating element of the cylinder or not.
  • the heating element stops consuming energy after a period of time in order not to exceed the maximum temperature of the cylinder (TMax). This is the maximum energy status (EMax).
  • the model can be applied by means of the following algorithms:
  • TMax is the maximum heating temperature of the cylinder and corresponds to the water temperature in the cylinder when this reaches maximum energy status (EMax). The user can provide this temperature manually or it can be easily measured as the maximum Thot temperature recorded. This maximum Thot temperature recorded will occur at any time of water consumption during a maximum energy status of the hot water cylinder.
  • Environmental losses of the hot water cylinder can be modelled by having two known energy statuses of the system at two separate points of time. This can be achieved by measuring the power fed into the system between two maximum energy statuses without any hot water demand between them. This is a common scenario which can also be met by controlling the heating element of the cylinder.
  • Et0 energy stored in the cylinder at point in time t0.
  • Et1 energy stored in the cylinder at point in time t1.
  • EPLoss energy loss between t0 and t1.
  • EPHeating energy employed to heat the cylinder between t0 and t1.
  • a more precise model would also take ambient temperature as an input to the Ploss model, which varies over time (PLoss(t)).
  • the actual thermal losses must be proportional to temperature difference between inside the hot water cylinder and ambient temperature (Tavg ⁇ TAmbient). If the tank starts the period in a maximum energy status, Tavg is known because it equals Tmax, the maximum heating temperature. This information can be utilised to train the adjusting of loss coefficients of the model.
  • the temperature of the tube will reach a stable state near ambient temperature when no hot water is being consumed.
  • the temperature of the outlet tube (where Thot is measured) will change following an exponential curve towards the water temperature from inside the cylinder (t1).
  • the demand of hot water starts precisely at this moment (t0).
  • the rate of the temperature change of the tube allows the amount of water mass being demanded (Q) to be estimated.
  • volume of flow is implicitly contained in A and B.
  • the total amount of water in the cylinder can be estimated along with the energy storage capacity.
  • TMin is the average temperature of Tcold during the process.
  • the energy stored in real time is calculated as the energy present at the previous point in time, by subtracting the used energy of hot water and the losses.
  • the water consumption and the user's behaviour models can be utilised to estimate future energy extractions through hot water consumption.
  • Models as simple as probabilistic prediction can be applied between extractions.
  • Other options include ARMA o GARCH models or adaptive neural networks.
  • Reinforcement learning models can also perform this task but, in general, prediction of water consumption is closely linked to the duration of extractions. For example, there are routines requiring consumption of hot water which can be characterised. For this reason, the duration of the extraction and the time between extractions are closely linked to each other. In this case, the prediction of both parameters together may lead to better results when predicting the user's behaviour.
