A high efficiency laminar flow burner system for proving a stream of heat energy including a supply input module for providing fuel and laminar streams of air to a combustion manifold. The combustion manifold includes an air-fuel mixing system, a stoichiometric unit, and a refractory unit each coupled to one another. A first combustion stream is established at the air-fuel mixing chamber system as fuel exits an injector device at direction perpendicular to the laminar air intake stream. A laminar air intake stream traveling from the supply input module and along the staging passageway passes through a stoichiometric unit body at a plurality of air intakes to meet with the first combustion stream within to define a second combustion stream for introduction from the stoichiometric unit to the refractory unit. The refractory unit thus defines a third combustion stream as the second combustion stream travels across a refractory passageway.

An extension device for remotely opening and closing a valve from a user knob is described. The device includes a flexible connector that allows the user knob to be positioned in various places relative the valve. One use for the disclosed device is with a gas grill, wherein the gas tank is placed in a position that is not easily accessible or is difficult for some persons to access. The extension device may be mounted in various positions on or near the grill allowing the user to open and close the gas tank's valve before and after use of the grill.

An intelligent heating system device is provided with processing, communications, and other information technology components, for remote monitoring and control and various value added features and services, embodiments of which use a renewable energy-powered electrolyzer to produce hydrogen as an on-demand fuel stream for a heating element of the heating system.

A method for controlling the operation of a burner, the burner including a control board with a first control unit and a first memory, which stores first values of operating parameters of the burner, and a display device, which displays one or more items of data relating to the functioning of the burner, the display device including a second memory, which stores second values of operating parameters of the burner, each first and second operating parameters being capable of being changed over time. The method includes setting for each operating parameter at least one first value in the first memory, and at least one second value in the second memory; comparing, for each operating parameter, a corresponding first value and second value; if the first value and the second value are different, changing one of the first or second values, so that the first and second values are the same.
