Abstract
Abstract A condensation reducing shroud assembly positionable around the inlet pipe of a water heater or the like. The assembly consists of a sleeve element which is positioned in a spaced-apart relationship about the portion of the water heater inlet pipe where condensation normally occurs. A spacing element is utilized to hold the sleeve in proper position, preferably by frictional force. By providing such a shroud assembly on the inlet pipe of a water heater, the accumulation and dripping of condensate which results from the temperature differential between the pipe and the heated air within the heater is eliminated or reduced by various thermal and evaporative processes. In an alternative embodiment, means are provided for trapping the condensate which forms and subsequently eliminating it through evaporation or drainage.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
188 words
In an improved heating apparatus of the type having a heating element, and an inlet pipe which is oriented in a generally vertical position and which carries water into an area of the apparatus near the heating element, the improvement comprising a shroud assembly positioned around the inlet pipe, the shroud assembly including: a. a sleeve surrounding the inlet pipe; b. attachment means for securing said sleeve to the inlet pipe in a generally vertical orientation, said attachment means including a resilient gripping element supported by said sleeve and forcibly abutting the inlet pipe to hold said sleeve thereon by frictional force between said gripping element and the inlet pipe; c. spacing means attached to said attachment means for positioning said sleeve about the inlet pipe with said sleeve being spaced apart from the inlet pipe; and d. a selectively controllable drain valve attached to said spacing means for draining from said spacing means any accumulated condensate which may form within said sleeve, said drain valve being controllably movable from a closed to an open position to allow the flow of condensate from an area within said sleeve.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
188 words
A shroud assembly positionable around the inlet pipe of a water heater to retard the formation and dripping of condensate on the inlet pipe, comprising: a. A sleeve positionable around an inlet pipe; b. attachment means for securing said sleeve to an inlet pipe, said attachment means including a resilient gripping element supported by said sleeve and forcibly abutable against an inlet pipe which may be inserted within said sleeve to hold said sleeve to an inlet pipe by frictional force; c. spacing means for positioning said sleeve in a generally vertical orientation about an inlet pipe to allow for the free convection of air between said sleeve and an inlet pipe which may be positioned within the sleeve; d. said spacing means containing an opening to allow for the free convection of air between said sleeve and an inlet pipe about which said sleeve may be positioned; and e. a selectively controllable drain valve attached to said spacing means for draining from said spacing means any accumulated condensate which may form within said sleeve, said drain valve being controllably movable from a closed to an open position.
