The high quality, stainless steel uniSTOR cylinder is a hot water storage facility, ideal for domestic properties with a new or existing sealed system or open vent boiler. uniSTOR cylinders are ‘unvented’ cylinders which mean they can operate efficiently under higher pressures, for example in a sealed heating system.

Key Features

  • Slim line, pre-plumbed and standard cylinders in the range
  • 2-year guarantee on parts and labour plus 25-year guarantee for the cylinder shell, giving you total peace of mind.
  • Can be retrofitted onto older systems meaning you can upgrade your cylinder without the hassle of the entire system.
  • Improved insulation means heat loss is minimised and lower running costs
  • Adjustable feet mean the cylinder can be installed on uneven ground.

General Information

Available in a wide range of hot water storage capacities, the uniSTOR is suitable for almost all types of property with a sealed system or open vent boiler. Being suitable in particular for larger properties with multiple bathrooms, heating systems using a cylinder can often provide a higher level of hot water than a combination boiler.

Vaillant uniSTOR unvented cylinders can be used when converting from an open vented system (with a cold water tank in the loft) to a sealed system (boiler and cylinder system). Converting to a sealed system can help save space e.g. during loft conversions etc when there is no room for a tank, and in most cases will provide higher water pressure at your taps and shower.

By upgrading an old copper cylinder (with insulation jacket) to a new uniSTOR unvented cylinder (as part of a heating system upgrade), you can make your heating system more efficient by reducing your cylinder heat losses significantly, which in turn can help to reduce your fuel bills.
