Abstract: A heating system and method of using such system in a building for zoned radiant heating. The system includes thermostatic radiator valves, each fluidly connected between at least one radiator in a zone of the building and a boiler. A controller is operatively connected to the valves to deactivate the valve positioners when the controller determines that valve activity is likely to have little to no effect on the output of the respective radiator and/or active heating of the building is not desired. For example, the controller determines when the boiler is deactivated and sends a deactivation control signal to the valves operative to prevent the valve positioners from adjusting the respective valve position. In another example, the controller sends the deactivation control signals to the valves at the onset of preprogrammed low usage periods of the heating system.

The heat exchanger is within the shell and is configured to exchange heat received from the heat source and a fluid within the heat exchanger. A first one of the at least two flame arrestors is at the inlet vent, and a second one of the at least two flame arrestors is at the outlet vent.

A plurality of fuel exit ports are disposed in the circumferential wall, and are directed generally inwardly toward the combustion chamber and upwardly from the bottom of the combustion chamber. The fuel exit ports are preferably directed inwardly at an angle that is slightly rotated from a central axis of the burner to create a swirling flame. A plurality of secondary air inlets extend through the bottom of the combustion chamber. An injector orifice is aligned with the central axis of the burner. The injector orifice is secured to the cooktop using a bracket, which has an orifice-securing surface, with two sidewalls extending therefrom and terminating in fastening flanges. The fastening flanges have asymmetrically arranged slots therein to receive tabs extending from the burner to ensure proper alignment of the burner and the injector orifice.

Abstract: A vehicular heat management system includes a heat medium circuit, a heat source portion, and a device. A heat medium cooling an engine circulates in the heat medium circuit. The heat source portion heats the heat medium. The device is configured to function and heat the heat medium when the heat medium flowing into the device is at or above a predetermined temperature. When the engine is being warmed up, heat generated by the heat source portion is supplied to the device in preference to the engine. According to this, since the heat generated by the heat source portion is supplied to the device in preference to the engine when the engine is being warmed up, the engine can be warmed up early.

Abstract: Systems, tools, and methods are presented that enable a circuit to introduce a random time delay before actuating a relay to start or stop a supply of electrical power to a heating element of a heating, ventilating, and air conditioning (HVAC) system. In one instance, the circuit includes a time-delay switch electrically connected to the relay. The time-delay switch has a random time delay before entering a closed state or open state. The relay is operable to start and stop a supply of electrical power to the heating element in response to the switch entering, respectively, the closed state and the open state. Other systems, tools and methods are presented.

Abstract: A system, apparatus, and method for a differential temperature managed integral, free standing, hydronic heating appliance uses a high-mass heat source coupled to a single, highly-efficient, variable speed, Electronically Commutated Motor (ECM)-driven Delta-T stand-alone system circulator which feeds one or more zone valves governing flow to one or more hydronic zones. Components are integrated into simplified, compact, assemblies. Zone valve packaging of a compact header improves hydronic performance (head pressure reduction and increased flow), complementing zone valve performance and reducing zone valve wiring labor and material content. Returns have full port valves and the boiler includes isolation valves. All manually activated valves are full port. This can include full port boiler isolation valves, circulator isolation valves and return valves.

Abstract: A promotion member is disposed a predetermined distance apart from an impregnation member disposed at an upstream side end of a combustion chamber, and an ignition device and a first air supply opening are prepared on an upstream side from the promotion member in an ignition space, and a second air supply opening is prepared on a downstream side from the promotion member in the ignition space. Fuel is supplied to a smooth surface of the impregnation member, and a concave part or cutout is formed in the impregnation member to house at least a part of the ignition device. A flow rate of air supplied to the combustion space through the second air supply opening becomes larger toward the downstream side. Thereby, ignitability in an evaporation type burner is improved and incomplete combustion of fuel on the downstream side of the combustion chamber is reduced.

Abstract: A device comprising a floating body/s that creates a meniscus that is either concave or convex in a liquid surface along a perimeter of the floating body/s, and a blade/s that are connected to the floating body/s which can change the direction of a flow of fluid, where there is another meniscus on the liquid surface that is curved in an opposing direction of the first meniscus so the second meniscus is able to repel the floating object from the first meniscus. If the first meniscus created by the floating body/s is convex, then the opposing meniscus on the liquid surface is concave, or if the first meniscus is concave, then the opposing meniscus is convex. Thus, embodiments can create various movements when fluid flow interacts with the blade/s, yet be repelled from areas on the liquid surface. Other embodiments are described and shown.
