The present invention provides a deep fat fryer providing an oil vat for holding hot oil. The hot oil of the vat is heated by a heat exchanger system that includes a pair of heat tubes. Heat transfer along a length of the heat tubes is facilitated by a heat conductive baffle substantially filling the interior of the heat tubes in volume and length. Heated air and gas are forced through the dense and elongated baffle to facilitate heat transfer to the walls of the heat tubes.

Exemplary embodiments are disclosed of self-configuring ignition controls or control modules (e.g., 120V/240V automatic self-configuring combined ignition and pool control for gas fired pool heating equipment, etc.).

A water heater includes a tank containing water to be heated and a thermal displacement conduit communicating between a portion of the tank and a receptacle. Water is displaced out of the portion of the tank, through the conduit, and to the receptacle during thermal expansion of the water during heating.

A system for boiling a fluid to produce a vapor through the reaction of one or more reactive gases within the fluid is generally disclosed. The system may include a gas meter to provide specific quantities of the one or more gases to a reaction zone. The system can include electrodes that are constantly operating. Once the one or more gases pass between the electrodes from the gas meter, the electrodes automatically ignite the gas or gases without requiring control systems to trigger the electrodes' operation. The vapor and/or resultant thermal energy generated by the system can be used to provide heat, steam, warmed water, and/or other reactants for use. The vapor generated by the system can be used for power generation to turn a turbine, to provide heat via a radiator, or for various other uses.

A control for a gas fired pool heater is configurable to operate at either a first voltage or a second voltage higher than the first voltage. The control includes an input voltage measurement circuit and an automatic voltage select circuit. The input voltage measurement circuit is configured to be operable for measuring an input line voltage to determine whether the gas fired pool heater unit is connected with the first voltage or the second voltage. The automatic voltage select circuit is configured to be operable for configuring the control for the correct input line voltage as measured by the input voltage measurement circuit.
