An apparatus and system for efficiently and safely transferring heat from a masonry heater to an external heating device using coil pipes and a liquid circulation pump. Circulation of a heat transfer liquid in the apparatus and system is controlled based on the measured temperature of the heat transfer liquid in the coil pipe on a return side of the masonry heater. Two additional sensors near the external heating device are used to control the flow rate of the circulation of the heat transfer liquid in the apparatus and system, thereby controlling the amount of heat actually transferred to the external heating device.

A heater system includes a heater bundle and a power supply device. The heater bundle includes a plurality of heater assemblies and a plurality of power conductors. The heater assembly includes a plurality of heater units, each heater unit defining at least one independently controlled heating zone. The power conductors are electrically connected to each of the independently controlled heating zones in each of the heater units. The power supply device is configured to modulate power to each of the independently controlled heater zones of the heater units through the power conductors.

The present disclosure belongs to technical field of thermoelectricity, particularly relates to a cogeneration apparatus, including a thermal collector and a thermoelectric power generation component, the thermoelectric power generation component is disposed on the thermal collector and an end face at one side contacts with the thermal collector, the cogeneration apparatus can collect the heat generated after gas combustion through the thermal collector, the heat is used for heating one end of the thermoelectric power generation component, so that two ends of the thermoelectric power generation component form a temperature difference, thereby realizing power generation. In this solution, a compensating distance is disposed between an upper end of the thermoelectric power generation component and an upper end of the thermal collector. The whole power generation efficiency of the apparatus is improved through a relationship between the output power of the thermoelectric power generation component and the compensating distance.

A fluid heating system may be installed for residential and commercial use, and may deliver fluid at consistent high temperatures for cooking, sterilizing tools or utensils, hot beverages and the like, without a limit on the number of consecutive discharges of fluid. The fluid heating system is installed with a tankless fluid heating device that includes an inlet port, an outlet port, at least one heat source connected with the inlet port, and a valve connecting the at least one heat source to the outlet port. A temperature sensor is downstream of the at least one heat source and connected to the valve. Another temperature sensor is on the heat source to enable it to be kept at an elevated temperature. The valve is operated so that an entire volume of a fluid discharge from the fluid heating system is delivered at a user-specified temperature on demand, for every demand.

A temperature controller for a heater for a container for use in hazardous areas and a method of programming such a temperature controller. The method of programming such a temperature controller comprises the steps of writing identification data and parameter data to a memory of a portable token in an area remote from the hazardous area; transporting the token to a position in proximity to the temperature controller in the hazardous area; transmitting, by means of near field communication, the identification data and parameter data stored in the memory of the portable token to a receiver in the temperature controller; comparing the identification data received by the temperature controller with identification data stored in a memory of the temperature controller; and if said comparison of identification data is positive, and updating parameter data stored in the memory of the temperature controller with the parameter data received by the receiver.

A gas water heater that includes a sheathed thermistor placed into the combustion chamber near a gas burner to provide for more accurate measurements of the temperature therein. The thermistor may be used in combination with a thermopile to provide additional measurements for determination of temperature conditions requiring a closure of a valve controlling the flow of gas to the burner

A system for monitoring temperature in the combustion chamber of a gas fueled water heater using a thermoelectric device placed near the gas burner. Based on the measured temperature, the water heater can determine whether abnormal operation is occurring that would require closing the flow of gaseous fuel to e.g., the main burner, pilot burner, or both.
