Horizontal Cylinders for Restricted Spaces

EXCELSIOR WZ horizontal water heaters are designed for domestic hot water systems where a standard vertical cylinder is not suitable. Their horizontal vessel design allows the unit to be installed in low-height or restricted spaces, such as loft areas, roof spaces and plant areas with limited clearance.

Built from stainless steel and supplied with mounting brackets, the WZ range provides a practical alternative to a vertical WD cylinder while still supporting reliable stored hot water. The range is available in direct and indirect models from 130 to 305 litres, giving installers flexibility across different system requirements.

Why EXCELSIOR WZ?

EXCELSIOR WZ water heaters are built for installations where space dictates the cylinder layout. By mounting horizontally, the vessel can be fitted into areas where a standard vertical cylinder would be difficult or impossible to install.

The range gives installers the choice of direct or indirect models, making it suitable for different domestic hot water system designs. Direct models use electric immersion heaters, while indirect models connect to an external heat source through an internal coil.

With stainless steel construction, mounting brackets and capacities from 130 to 305 litres, EXCELSIOR WZ provides a practical horizontal solution for reliable hot water storage in restricted installation spaces.
