## Long description

Kaps open horizontal expansion vessel 20 L with handles for central heating is a horizontal cylindrical tank designed to accommodate thermal expansion in closed central heating systems. With a 20-litre capacity and integrated handles, the vessel is intended to reduce pressure fluctuations, protect pumps, valves and piping, and provide a compact solution for residential and light commercial heating installations where a horizontal layout is required.
Advantages
The horizontal design with built-in handles simplifies handling and installation in tight spaces and supports stable positioning on brackets or shelves. The open construction provides straightforward connection to the heating circuit and allows visual inspection of water level and venting. Corrosion-resistant materials and robust welds ensure reliable operation under typical heating conditions, while the 20 L capacity offers effective compensation for daily thermal expansion in small to medium-sized systems.
