The Vaillant uniSTOR 180 Unvented Hot Water Cylinder is a high-performance hot water storage solution designed for sealed heating systems. It is an ideal option for homeowners upgrading from an open vented system with a cold water tank in the loft to a modern sealed system with a boiler and unvented cylinder. This upgrade not only saves space by removing the need for a loft tank, but also significantly improves hot water pressure throughout the property.
With a 180 litre capacity, this cylinder is well suited for medium to larger households with higher hot water demand. It is manufactured from high-grade duplex stainless steel, providing excellent durability, corrosion resistance, and long service life.
The uniSTOR cylinder is highly insulated using environmentally friendly materials, helping to reduce heat loss and improve overall heating system efficiency. This improved efficiency can help reduce energy usage and lower fuel bills over time. The cylinder also features a clean, modern outer casing that is easy to maintain and designed to fit neatly into airing cupboards or utility rooms.

Why Choose an Unvented Cylinder?
Unvented cylinders deliver hot water at mains pressure, meaning stronger showers and better water flow from taps compared to traditional vented systems. They also remove the need for a cold water storage tank in the loft, freeing up space and simplifying the system. Modern unvented cylinders like the Vaillant uniSTOR are also highly insulated, helping to reduce heat loss and improve energy efficiency.
