A thermostatic device for a pipeline of a sanitary water supply or dispensing system and including a temperature meter which detects the temperature of the sanitary water entering the thermostatic device, a flow regulator which regulates a rate of sanitary water exiting from the device, and a control unit. The flow regulator operates in a first operating mode and a second operating mode. The first operating mode is a steady-state operating mode. The second operating mode is a steady-state setting operating mode in which the flow rate of sanitary water leaving the thermostatic device is a minimum flow rate. The control unit is configured to acquire, receive and/or calculate a reference temperature and arrange the switching of the operating mode when the temperature meter detects a temperature of the sanitary water greater than the reference temperature.

The present invention relates to a safe heater based on environmental analysis, wherein the heater comprises: a heater body, which comprises a housing, a safe metal cover, a reflective cover and a power switch, wherein the power switch is used for connecting a 220V alternating current, the safe metal cover is arranged at the periphery of the reflective cover, and the housing is arranged at the periphery of the safe metal cover; an image collection device for performing panoramic image data collection on the position where the heater body is located so as to obtain and output a corresponding high-definition panoramic image; an ultrasonic emission device, which is arranged on the image collection device, and is used for emitting an ultrasonic signal towards the ground and recording the time when the ultrasonic signal is emitted; and an ultrasonic receiving device, which is arranged on the image collection device, is located near the ultrasonic emission device and is used for facing the ground to receive the ultrasonic signal reflected by the ground and emitted by the ultrasonic emission device. The safety performance of the heater can be improved by the present invention.

A hot water heating system is provided with: a hot water heating device; a heating terminal; a heat circulation circuit; a circulation means; and an expansion-absorbing means. The hot water heating device is provided with: a heating passage; a heating means for heating a heat medium inside the heating passage; a pressure detection means; a supply passage connected to the heating passage; an opening/closing means for the supply passage; and a control means which opens the opening/closing means to supply the heat medium when the internal pressure of the heating passage is less than a reference value. The control means determines that the positional relationship between the circulation means and the expansion-absorbing means is inappropriate when the pressure detected by the pressure detection means at the moment the circulation means starts to be driven is lower than the pressure detected prior to driving the circulation means.

A method for constructing a water circulation device including a water circulation circuit that circulates water heat-exchanged with a refrigerant heated by a heat pump includes: installing a heater in the water circulation device in contact with the water; depositing scale from the water on the heater by heating the heater while circulating the water in the water circulation circuit; and removing the heater from the water circulation device after the depositing.

An automatic switching device is described to switch on an electric heater based on a user wearing a down jacket and switch off the electric heater based on the user not wearing a down jacket. The automatic switching is based on an image collection unit collecting an image of the user, and an image processing unit processing the image to determine if down jacket is in the image. The image collection unit may be adjusted to a position so that it may collect the image between a shoulder and a waist of the user. The adjustment of the position is based on a measured distance between the image collection unit and a floor by an ultrasonic transducer. Since the velocity of sound in air varies with the ambient temperature, a temperature unit is utilized to detect the ambient temperature so that an accurate velocity of sound may be retrieved from a table.

The instant hot water system CONTROL PANEL for new homes is an on-demand controller for a common residential water pump, installed at the hot water supply/recirculation hot water pipe line back to the regular residential gas or electric water heater, with push button switches in every bathroom, kitchen, laundry room etc. to pump hot water at the touch of said button; from the water heater to faucets throughout the house and dispense the hot water to the user, with no waiting time and very minimal cold water waste down the drain because the hot water has already reached every single faucet in the house as the users with the push of a button demanded it.

A system and a method for controlling an electrical water heater as per a load shedding request signal are disclosed. A temperature sensor is positioned so as to measure a water temperature in a lower area of a tank of the water heater to be controlled. A controller continuously determines a salubrity index of the water heater as a function of the temperature measured by the sensor and a time measurement, and decides to interrupt an electrical power supply of the water heater through a switch so as to interrupt or not interrupt an operation of the water heater upon the load shedding request signal and only if the salubrity index meets a preestablished criterion.

A control system of a water heater apparatus with a combustible gas burner is presented where the apparatus includes a pilot burner with an intermittent-type pilot flame, a main burner, a pilot valve and a main valve, a control unit, a flame detection electrode, introduced into the flame of the pilot burner, and which is configured to conduct an ionization current. The control unit is configured to measure/detect a variation involving increase/decrease of the intensity of ionization current detected, the variation in intensity of ionization current being generated during the change between a first condition, in which the ionization current identifies the ignition state of only the pilot burner, and a second condition, in which the ionization current identifies the simultaneous ignition state of the pilot burner and the main burner so that, by detection of the measurement/variation of ionization current, the effective ignition of the main burner is recognized.

The wireless wall thermostat of the present invention utilizes a push-contact mechanical system that allows a user to raise or lower the temperature within a space by applying a force on the top or bottom center of the front of the thermostat. The perpendicular force applied by the user generates a moment arm around pivot connectors, which rotates the thermostat clockwise or counter-clockwise. When rotated clockwise or counter-clockwise, contact buttons attached to the back of the thermostat come into contact with the trigger tabs of a stationary trigger plate mounted to a wall through use of an electromagnetic attraction between a steel disc and a magnet. When the trigger tabs press the contact buttons, the contact buttons send a signal to the central processing unit of the thermostat's internal circuit board to modulate the temperature setting. In addition, the wireless wall thermostat can be detachable by utilizing a magnetic release smart mount.
