A heating system includes heaters configured to heat a liquid contained in a tank. Each of the heaters includes a heating element, a temperature sensor coupled to the heating element, a control unit in communication with the heating element and the temperature sensor. The control unit is configured to control the heating element and the temperature sensor. The heating system includes a smart probe in communication with the control unit of one of the heaters and configured to monitor operation conditions of the heating system. The heating system includes a display and an indicator coupled to the control unit. The heaters are integrated in a mesh network operatable under Internet-of-Things (IoT) connectivity.

A fluid sensing system and approach having a leak sensor. The leak sensor may output a signal when a fluid is detected. The signal may go to an alarm circuit which can sound a warning or alert. The signal may also go to a control interface of a piece of equipment, such as a water heater, to shut off the piece equipment in an event that it is causing a leak of fluid. Also, the sensing system may have a low battery sensor and indicator in case a battery supplying power for the sensing system is running low. The sensing system may be made of analog circuitry and discrete components.

A method of operating a water heater in a load shed mode can include detecting that an upper water heater thermostat control module in a water heater is calling for heat to be provided via an upper heating element of the water heater while the water heater is in a load shed mode of operation wherein a first leg of power to the water heater is decoupled from an input to the upper water heater thermostat control module and responsive to the upper water heater thermostat control module calling for heat, transmitting a signal to end the load shed mode of operation at the water heater so that the first leg of power to the water heater is coupled to the input of the upper water heater thermostat control module so that the upper heating element of the water heater is enabled to heat water responsive to the upper water heater thermostat control module calling for heat.

An apparatus and method for heating water using tankless water heater with improved rain cap.

An apparatus and method for heating water using a tank or a tankless water heater with improved electronic control.

Embodiments relate generally to a heated towel rack that includes at least one lateral support, at least one forced air heating unit in fluid communication with a channel within a lateral support, and at least one cross bar coupled to the at least one lateral support. The at least one cross bar including at least one vent that traverses into a conduit within the cross bar. The channel is in fluid communication with the at least one vent by way of the conduit.

A hot water tank including: a shell enclosing a chamber containing a heat exchange liquid, the shell including a base, side wall and lid; a cold water inlet connected to a first end of a heat exchanger, and a hot water outlet connected to a second end of the heat exchanger, wherein the heat exchanger is located in an upper portion of the chamber; a primary heating element connected to a power source for heating the heat exchange liquid, the primary heating element being located in a lower portion of the chamber.

A water preconditioner system comprising a user interface for manually or automatically receiving inputs from a user, a mixing assembly including a plurality of control valves coupled to hot and cold water supply lines, and a controller in communication with the plurality of control valves and the user interface for controlling the operation of the system. The controller is configured to operate in a plurality of modes to precondition the water to one of a desired preset water dispensing temperature or a target temperature different from the desired preset water dispensing temperature.

A fuel-fired device can include an air-moving device that mixes air and a fuel to generate a fuel-air mixture. The fuel-fired device can also include an air box that provides the air to the air-moving device, and a fuel valve that provides the fuel to the air-moving device, where the fuel valve includes a tracking port coupled to the air box, where the tracking port detects a pressure of the air box. The fuel-fired device can further provide a pressure-regulating device disposed between a pressurized component and the tracking port of the fuel valve. The flow regulating device can control, during an ignition phase of operation, an amount of the fuel provided by the fuel valve to the air-moving device.
