Indirect Unvented Cylinders

Here at PlumbNation, we provide an extensive range of Indirect Unvented Cylinders, perfect for both commercial and domestic properties. Used to provide heated water in your bathroom and kitchen, cylinders are an integral part of your home. Unvented cylinders work off the mains pressure water in your property, which often results in a better flow of hot water.

These indirect unvented cylinders are cleverly designed to store and supply hot water throughout your property by heating your water using your heating system. By using the heating system already in your property, an indirect unvented cylinder saves valuable storage space, ideal for buildings with limited space.

Discover our collection of indirect unvented cylinders below, boasting a variety of capacities and sizes to suit everyone.
