Abstract: The present invention is a spraying system that extinguishes flying embers that may land on a roof from brush fires or forest fires. This includes a submersible pump at the bottom of a well that is attached to a supply pipe that allows water to be pumped into a reservoir. Another submersible pump is inside the reservoir that pumps water thru a supply pipe that is attached to the roof. This area is called a water station that may also be equipped with a generator for a backup power source. The supply pipe has pipe couplings attached at certain intervals and has sprayers installed into the couplings. These sprayers will then give off an adequate amount of water to soak down the entire roof area in the event of an approaching fire. All of this is assembled and placed in specially designed roof fasteners that are installed throughout the entire hip and ridge of the roof.

Abstract: The invention relates to a fire protection system consisting of a first fire protection barrier in the form of a fire protection glass pane provided with preferably monolithic glass panels (1), and a device (2) for spraying water in the form of a water spray haze (7), in front of the fire protection glass pane. The inventive fire protection system ensures, in the event of a fire, that an additional transparent fire protection barrier is provided, that heat and smoke in the room (4) swept through by the fire mix together, and that exposed escape routes, inter alia, are thus protected from dangerous heat radiation (9). The inventive fire protection system can be used in very different fields of application, e.g. for interior glass panes or screens.

Abstract: Wood-burning pool heaters are not designed to automatically extinguish their fires when the water flow through the heater is interrupted. In these situations, the water remaining in the heater would be heated sufficiently to melt the pipes connecting to the pool pump and filter system, which could possibly damage the heater, as well. Manufacturers of wood-burning pool heaters warn users to extinguish the fire immediately. The present invention provides an automatic means of extinguishing the fire immediately, without any user intervention.
