摘要： The invention provides a water tank heating method and unit, an electronic device and a solid oxide fuel cell (SOFC) system. Before the SOFC system is started, ice in a water tank has been heated up, so after the SOFC system is started, the heating time of the heated ice, i.e., the thawing time of the water tank, will be shortened. Further, in the ice heating process, a pre-set needed SOFC thawing time determined according to current stack outlet temperature is used as a heating control parameter. As the stack outlet temperature is a key factor influencing the starting time of the SOFC system, the heating control will be more accurate if the pre-set needed SOFC thawing time corresponding to the stack outlet temperature is used as a heating control parameter.

摘要： Disclosed herein are WIFI and cloud enabled temperature control systems. The temperature control systems are configured to receive user temperature settings and preferences, and control a water heater based on the user temperature settings and preferences. The temperature control systems include two or more sampling rates for enabling a higher efficiency of operation compared to conventional water heaters.

摘要： The present disclosure discloses a defrosting control method, a central controller and a heating system. The defrosting control method comprises: heating fluid in a flow passage between an inlet and an outlet of a first heat source by a second heat source, at least in a part of process of defrosting by the first heat source; acquiring an operation parameter of the first heat source, wherein the operation parameter comprises a water outlet temperature and/or a water return temperature and/or an operation parameter of a compressor of the first heat source, comparing a current value of the acquired operation parameter with a preset range of the operation parameter, and adjusting a heat exchange amount between the second heat source and the fluid when the acquired current value is within the preset range. The defrosting control method, the central controller and the heating system provided by the present disclosure can improve the defrosting efficiency while considering the heating comfort, and ensure the stable operation of the defrosting process.

摘要： A freeze protection system is provided that includes a first valve configured to be coupled with an inlet of a water heater, such as a tankless water heater; a second valve configured to be coupled with an outlet of the water heater; and a valve actuator configured to automatically actuate the first valve and the second valve to permit water to drain from the water heater when (1) electric power is lost to the water heater, and (2) a temperature of a fluid in or around the water heater is less than or equal to a predetermined low temperature threshold.
