In some aspects, deicer systems to distribute a deicing fluid along a roof of a building to limit ice dam formation can include: a pre-pressurized water source that provides pressurized water; a deicer solution source containing a deicer solution; a passive mixing system in fluid communication with the pre-pressurized water source and the deicer solution source, the passive mixing system being configured to combine the pressurized water and the deicer solution to form a deicer fluid; and one or more emitters configured to be disposed along the roof, the emitters being in fluid communication with the passive mixing system to receive the deicer fluid and dispense the deicer fluid along the roof. In addition, certain systems described herein can be run with an electric pump.

A repositionable roof clip assembly may include a mounting block including: a first wall, a second wall, a top wall joining the first wall and second wall and creating a gap therebetween; and at least one cable clamp including: a lower guide, an upper guide; and a bendable member joining the lower and upper guides and can be bent over a heating cable such that the heating cable is trapped between the upper guide and the lower guide.

The present invention relates to a vent pipe de-icing system that has a first external pipe, a first internal pipe, a second external pipe and a second internal pipe. The external pipes sit above the top surface of a vent pipe, and the internal pipes sit within the vent pipe. The internal pipes are connected to a hot water tank and or pump that pumps hot water or other heated fluid through the pipes such that the heated fluid exits the external pipes and falls into the inside surface of the vent pipe. In this manner, the device can be used to continuously defrost or de-ice a vent pipe and prevent ice from forming. The device can further be controlled via a mobile application, which allows a user to control when and how much fluid is pumped within the device.

A deicer system for distributing deicer solution along a structure. The deicer system includes a deicing solution reservoir that contains the deicer solution, a pump, and one or more emitters. The pump is in fluid communication with the deicer solution reservoir and the pump is configured to distribute the deicer solution. The one or more emitters are in fluid communication with the deicer solution reservoir and the pump. The one or more emitters are positioned in a housing that is integrally connected to the structure. The one or more emitters are configured to dispense the deicer solution along the structure.

A snow and ice melt system for a roof may feature heat plates which protect and contact heat cable to distribute heat over a wider area than cable alone. Bends in the plates create attachment structures by which the plates are assembled and by which heat cable is contained.

Structure heating systems and methods of making and use. One embodiment has a unitary or integral roof edge heating element with a single heating cable mounted in a heating cable channel running laterally through the heating element and a roof edge heating panel extending from the portion of the heating element bearing the heating cable. Another embodiment includes a single heating cable mounted in a heating element surrounded by a heating element cover. Some embodiments can reduce the amount of heat transfer contact with supporting roof or adjacent structure, reducing heat transfer to the supporting roof or other adjacent structure.

A snow and ice melt system for a roof may feature heat plates which protect and contact heat cable to distribute heat over a wider area than cable alone. Specially tailored ends in the plates create attachment structures by which the plates are assembled, and by which heat cable is contained. Specially formed caps cover roof valley locations with specially engineered folds and channels tailored to protect the cable in these valley locations and allow heat panel stacking and interlocking to cover an entire roof.

An apparatus for heating structure or areas adjacent such structure, such as a roof on a building for example, exposed to varying weather conditions and methods of making and use of the apparatus. The heating apparatus can include a heating element and heat supplying components. In one embodiment, the heating apparatus also includes a heatable cover panel and fasteners or other fastening components or materials for securing the heating element and cover panel to the structure. The heat supplying components may include one or more heater cable or heater cable sections penetrating one or more heater cable channels in the heating element. The apparatus may also utilize various insulating and other materials, including paint on exposed surfaces of the apparatus.

A roof ice melt system and method of making and use to reduce or eliminate water from puddling or not running down the ice melt system and off of the roof. One embodiment of the roof for the roof ice melt system can has a slope of between approximately 0.5/12 and approximately 2.5/12. The roof ice melt system has a heating element and heatable cover panel having a a primary heating element cover section, an upper roof contacting section, and an intermediate cover section extending between the primary heating element cover section and the upper roof contacting section. The intermediate cover section is sized so that it extends downwardly along the roof, rather than horizontally or higher, from the upper roof contacting section toward the primary heating element cover section.

A fluid deposition system is provided. The system comprises one or more electronic processors, and one or more electronic memories each electrically connected to at least one of the one or more processors and having instructions stored therein. The processor(s) is/are configured to access the memory or memories and execute the instructions stored therein such that the processor(s) is/are configured to: determine whether one or more predetermined criteria are met for initiating deposition of fluid onto an area of interest; when it is determined that the criteria is/are met, determine one or more operating parameters of the fluid deposition system to use in the deposition of the fluid onto the area of interest; and following the determination of the operating parameter(s), generate one or more electrical signals to cause the fluid to be deposited onto the area of interest in accordance with the determined parameter(s).
