A method of controlling a gas powered water heater includes attempting to pick a main gas valve of the main burner using a first pick method. The first pick method includes closing a switch of a valve pick system to couple a capacitor of the valve pick system to the main gas valve for a first length of time to discharge energy stored in the capacitor to the main gas valve, and opening the switch of the valve pick system after the energy stored in the capacitor is discharged to the main gas valve. The controller determines if the main gas valve is open after using the first pick method. When the controller determines the main gas valve is not open, the controller attempts to pick the main gas valve using a second pick method different than the first pick method.

An apparatus includes a high-pressure tank, a controller, a valve, controlled by the controller, and a heater.

A LWCO remote monitoring and diagnosing system or device features a signal processor configured to: receive signaling containing information for running a remote low water cut off (LWCO) mobile application, and also containing information about historical data related to a LWCO circuit that monitors and controls a burner of a boiler that opens and closes to provide water to the boiler depending on the water level in the boiler; and determine corresponding signaling containing information about the historical data requested based upon the signaling received.

A method for detecting malfunction of an electric boiler, the method including: a) detecting over scale accumulation by the steps of: metering the boiler's heating cycle, being a time from activating the boiler by a thermostat thereof until deactivating the boiler by the thermostat; if the heating cycle is longer than a threshold, then indicating over accumulation of scale in the boiler; b) detecting a malfunction of insulation of the boiler, by the steps of: metering the boiler's cooling cycle, being a time from deactivating the boiler by a thermostat thereof until reactivating the boiler by the thermostat; if the cooling cycle is shorter than the threshold, then indicating malfunction of insulation of the boiler; thereby allowing indicating malfunction of said boiler only by metering the heating and cooling cycles of said boiler.

One or more techniques and/or systems are disclosed for a portable heater that may be used in an area used for human occupancy, to provide heat to that area. Such a heater can be portable, and comprise an environmental detector that senses ambient air conditions, and may provide data used to shut down the heater in threshold conditions. In one implementation, a portable heater for use in high altitudes can comprise a housing configured for portability, in which a combustion region and a fuel supply component are disposed. The heater can comprise an environmental detector with a flameless sensor configured to detect an ambient level of a constituent of the atmosphere, and generate a signal indicative of the constituent level; and a sensor interface that can control flow of fuel from the fuel supply, based at least upon a signal received from the sensor.

A method and system for providing an interactive learning heating schedule for a water boiler system, the method including the steps: (a) receiving an estimate of an amount of available hot water in a water boiler of the water boiler system; (b) receiving usage data for the water boiler system, the usage data including at least one expected usage pattern extrapolated from the usage data; and (c) generating a heating schedule for the water boiler, based on at least one expected usage pattern and the estimated amount of available hot water.

A water heating system can include a water heater having a tank, an inlet line, and an outlet line, where the inlet line provides unheated water to the tank, and where the outlet line draws heated water from the tank. The water heating system can also include multiple sensing devices, where each sensing device of the plurality of sensing devices measures a parameter associated with the tank. The water heating system can further include a controller communicably coupled to the plurality of sensing devices, where the controller determines an amount of heated water in the tank based on measurements made by the plurality of sensing devices.
