Water heater drain pan describes this Killarney Metals KM-09852 pan designed to sit under a heater and capture water where it falls. The 13 inch width focuses the coverage beneath compact or tankless style heaters, so runoff stays controlled around the footprint. The 20 inch length extends that protection along the unit, helping catch drips or minor discharge that might otherwise reach adjacent surfaces. With a 2-1/2 inch height, the pan provides vertical capacity to hold water before it reaches surrounding areas, giving time for drainage systems downstream of the pan to handle flow. Galvanized steel construction builds in a rigid base under the heater, supporting daily service conditions in a shop or utility setting. The rectangular shape aligns cleanly against walls or framing, which simplifies heater positioning over the pan and supports a tidy, professional layout in the mechanical area.
This 13 inch wide by 20 inch long pan sets the basic footprint that installers work around when positioning a water heater. The compact width allows placement in narrow alcoves or between existing equipment runs, while the 20 inch length gives additional catch area without consuming excessive floor space. At 2-1/2 inches high, the side walls rise enough to create a visible containment boundary, which helps with leveling the heater base relative to the rim. Galvanized steel construction supports typical mounting loads from a heater resting on the pan surface, allowing the unit to be set directly into position. The rectangular geometry makes it straightforward to square the pan to framing or walls, supporting clean pipe routing and predictable clearances around the heater body.
The KM-09852 galvanized steel drain pan fits applications calling for a 13 inch by 20 inch footprint under a water heater. The relatively narrow width works where mechanical spaces are constrained, such as utility closets, small shop corners, or tight service chases. The 20 inch length gives a proportionally longer catch area that aligns well beneath many compact or tankless style heaters. With 2-1/2 inch tall sides, the pan creates a defined containment zone that helps direct water toward a chosen drainage route at floor level. Galvanized steel makes the pan suitable for typical indoor shop or building service locations, where light moisture exposure and ongoing equipment work are expected. In multi-unit installations, the consistent rectangular dimensions simplify repeating the layout across several heaters along a wall.
The specified 13 inch width and 20 inch length allow installers to plan framing, clearances, and pipe locations around a fixed, known footprint, reducing layout guesswork from one job to the next. The 2-1/2 inch height gives a predictable sidewall dimension, which helps in coordinating adjacent floor finishes or thresholds and avoiding conflicts at door swings near the heater. Galvanized steel construction contributes a stable bearing surface for the heater, so shims or supports can be planned against a firm base rather than a flexible tray. The rectangular shape with straight sides and square corners makes it easier to align multiple pans along a common reference line, which is useful in commercial or shop banks of heaters. Using the KM-09852 part number across similar projects also standardizes the pan size, supporting consistent material takeoffs and repeatable detailing.
The KM-09852 water heater drain pan measures 13 inches wide, 20 inches long, and 2-1/2 inches high, so installers can plan the heater footprint and surrounding clearances around that fixed rectangle.
The KM-09852 pan is made from galvanized steel, providing a rigid base under the water heater that suits typical indoor shop, utility, or mechanical room environments.
The SAP description identifies the KM-09852 as a tankless water heater pan, so its 13 inch by 20 inch footprint targets compact or tankless style heater layouts.
This Killarney Metals drain pan has 2-1/2 inch high sides, giving a defined containment edge that provides holding depth before any overflow reaches surrounding surfaces.
The KM-09852 pan is a rectangular 13 inch by 20 inch format, which aligns cleanly along walls or framing and supports straightforward heater positioning.
This water heater drain pan is manufactured by Killarney Metals, identified by part number KM-09852, so it aligns with that specific product line.
The KM-09852 galvanized steel water heater drain pan from Killarney Metals gives a defined 13 inch by 20 inch footprint with 2-1/2 inch high sides tailored to compact or tankless heater layouts. That combination of width, length, and height helps control water near the heater while still fitting into tighter mechanical spaces. For projects where a rectangular, galvanized steel pan in this size range matches the heater base, selecting this part number supports consistent layouts across installs.
