## Summary description

Open horizontal expansion vessel by Kaps, model C413503015, with 15‑liter capacity and integrated handles for mounting and transport. Designed for central heating and hot water systems to accommodate thermal expansion in closed circuits where an open-type reservoir is required. Suited for installations needing a compact horizontal tank with manual handling points.

## Long description

Open horizontal expansion vessel Kaps C413503015 — Open Horizontal 15 L with Handles is a 15‑litre open-type tank designed for central heating and hot water installations that require an open reservoir to accommodate thermal expansion. The horizontal layout with integrated handles provides a compact footprint and manual handling points for installation and routine maintenance. The vessel is intended for systems where fluid expansion must be collected in an atmospheric or vented expansion arrangement rather than in a closed, pressurised membrane tank.
Advantages
The horizontal design reduces the vertical space required and simplifies siting in plant rooms or under boilers. Integrated handles allow safer and easier carrying, positioning and mounting by one or two installers. As an open expansion vessel, it supports atmospheric venting and is compatible with systems that incorporate feed and vent arrangements. The product is manufactured for robustness and straightforward mechanical connection to existing piping and supports manual inspection and maintenance.
Suitable for
 Central heating systems requiring an open/vented expansion reservoir
 Domestic and small commercial hot water heating circuits
 Installations with limited vertical space where a horizontal tank is preferred
 Retrofit projects needing a compact expansion vessel with handling points
Key specifications
 Type: open (vented) expansion vessel, horizontal orientation
 Nominal capacity: 15 litres
 Form factor: compact horizontal tank with integrated handles for manual handling
 Application: designed for central heating and hot water systems to accommodate thermal expansion
 Connection: mechanical pipe connections suitable for feed, return and venting arrangements (connection sizes vary by installation)
 Material and construction: corrosion-resistant coated steel suitable for typical heating system environments
 Mounting: designed for horizontal mounting on flat surfaces or within plant-room racks
How to use
Install the vessel in a location that allows access for inspection, venting and routine maintenance while observing local regulations for open expansion systems. Secure the tank in a horizontal position using appropriate supports or brackets, and connect to the system feed, return and vent lines per the system design and applicable plumbing codes. Ensure the vent is routed to a safe discharge point and that air separation and make‑up water arrangements are provided according to the installation schematic. After connection, perform a visual inspection for leaks and verify free venting and correct positioning before commissioning the heating system.
Usage recommendations
Use this open expansion vessel only in systems designed for atmospheric venting and provide routine visual checks for corrosion, sediment and proper vent operation. Keep the vessel accessible for maintenance and ensure venting and make‑up water components are sized correctly for the system volume and expected thermal expansion.
