## Title
Ice and snow removal system

## Abstract

One or more dispensing conveyances (1) have outlet apertures (2) or conveying and dispensing heated water to surfaces of roofs (3) and other structural surfaces selectively when ice and snow is being accumulated or has accumulated thereon. The water is heated with an electric-resistance (7, 10) or optionally with a fuel-flame heater (8, 11), which can be a tank heater or a tankless geyser water heater. Electric-resistance members can be positioned inside of heat-resistant tubular conveyances proximate the outlet apertures. A programmable control unit (18) can be included for programmable heat, flow rate and flow time.

## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to removal and prevention of accumulation of ice and snow on roofs and other surfaces by dispensing heated water onto the roofs or other surfaces from a dispenser conveyance.
2. Relation to Prior Art
Accumulation of ice and snow on roofs, driveways, bridges, and other structural surfaces has long been a problem in cold climates. Prior art generated for its prevention and removal has included variations of circulating heated water or heated air in heat-radiation conveyances on the roofs and other critical surfaces. There is no known ice-and-snow-removal system that dispenses heated water onto the roof or other structural surfaces from a dispenser in a manner taught by this invention.
Examples of most-closely related known but different devices are described in the following patent documents:

SUMMARY OF THE INVENTION
Objects of patentable novelty and utility taught by this invention are to provide an ice-and-snow removal system which:
can be used to prevent or to remove accumulation of ice and snow from roofs and other structural surfaces;
can be made portable for use on select roofs and other surfaces; and
can be positioned wherever found to be most effective on roofs, driveways, bridges and other structural surfaces.
This invention accomplishes these objectives with one or more tubular conveyances having outlet apertures for conveying and dispensing heated water to surfaces of roofs and other structural surfaces selectively when ice and snow is being accumulated or has accumulated thereon. The water is heated preferably, but not necessarily, with an electric-resistance geyser to avoid tankage losses. Electric-resistance members can be positioned inside of the conveyances proximate the outlet apertures and the tubular conveyances can be heat resistance to further economize the system.

Referring to FIGS. 1-2, at least one dispensing conveyance 1, which is preferably a tubular member, has at least one outlet aperture 2 for conveying and dispensing heated water to a surface of a roof 3 or other structural surface selectively when ice and snow is being accumulated or has accumulated thereon. A water-source conveyance 4 is in fluid communication of water from a water source 5 to the dispensing conveyance 1. The dispensing conveyance 1 is articulated to be positioned on or above the roof 3 of other structural surface predeterminedly.
A water heater is positioned intermediate the water source 5 and the outlet aperture 2. As shown in FIG. 1, the water heater can include a water-heater tank 6 that has optionally an electrical-resistance heater 7 or a fuel-flame water heater 8.
Optionally, as shown in FIG. 2, the water heater can include a geyser water heater 9 having tankless fluid communication intermediate the water source 5 and the dispensing conveyance 1. The geyser water heater 9 can include an electric geyser heater 10 or a fuel geyser heater 11.
Referring to FIGS. 3-6, the electric geyser heater 10 can include an electrical resistor 12 in the dispensing conveyance 1, which is preferably the tubular member. Electrical current to the electrical resistor 12 can be routed from an electrical source 13 through an electrical lead 14.
The tubular member of the dispensing conveyance 1 can include heat-resistance walls 15 as shown in FIGS. 5-6 for resisting dissipation of heat from water heated in the tubular member prior to dispensing of the water as heated water on the roof 3 or other structure.
Generally, the roof 3 or other structural member is slanted and the dispensing conveyance 1 is positioned proximate a predeterminedly high position vertically on the roof 3 or other structural surface for allowing flow of heated water from the at least one outlet aperture 2 for heat exchange from the heated water to ice and snow on the roof 3 or other structural surface selectively as shown in FIGS. 1-4.
