Horizontal

Unvented Horizontal Cylinders are compact, high-performance hot water storage solutions designed for properties with limited vertical installation space. They deliver powerful mains pressure hot water without the need for a cold-water storage tank, offering the same efficiency and performance as traditional vertical unvented cylinders.

About Unvented Horizontal Cylinders

Unvented Horizontal Cylinders are ideal for homes or commercial properties where headroom or floor space is restricted—such as lofts, basements, or underfloor areas. These cylinders are horizontally oriented and built from high-grade stainless steel for durability and corrosion resistance. They operate as sealed systems, connected directly to the mains water supply, ensuring consistent high-pressure hot water throughout the property.
