Abstract

The invention relates to a water heater having remote temperature feedback, comprising a water heater, a control module, a remote temperature sensor module, an electric hydro-generator, a wireless communications module and a control panel that permits the user to activate the heater and select the desired temperature, which is achieved by obtaining the temperature reading at the point of service of the hot water when the water moves towards the electric hydro-generator, which activates the remote temperature sensor module, and sending same to the control module which uses the data as an entry in the closed control loop using a PID algorithm. The object of the invention is to provide a water heater that can achieve a precise temperature according to the adjustment made by the user without the user needing to mix in cold water to achieve the desired temperature.
