Product Information

Overview

The Vaillant Unistor Indirect 180 is designed to support dependable stored hot water performance in domestic heating systems. It can form part of a wider installation where the right boiler parts and compatible components are needed for long-term reliability. For heating engineers and homeowners comparing boiler accessories, this product helps complete a practical hot water setup.

The Vaillant uniSTOR 180L Unvented Indirect Cylinder is a high-quality hot water storage solution, designed to deliver reliable, efficient hot water for medium-sized domestic properties. It is ideal when converting from an open vented system (with a cold water tank in the loft) to a sealed boiler and cylinder system, helping to save space while improving water pressure throughout your home.

Performance and Efficiency

  • 180-litre capacity - perfect for medium-sized households
  • Duplex stainless steel construction - durable, corrosion-resistant, and long-lasting
  • Highly insulated with eco-friendly materials - minimises heat loss and lowers running costs
  • Unvented design - operates efficiently under higher pressures for strong water flow at taps and showers
  • Improves heating system efficiency - upgrading from an old copper cylinder reduces cylinder heat losses and can lower fuel bills

Installation and Convenience

  • Compact design - space-saving solution when replacing older systems
  • Aesthetically pleasing, easy-to-clean outer casing - blends seamlessly into utility rooms or cupboards
  • Suitable for conversions - ideal for upgrading existing open vented systems to sealed systems

Built from high-grade duplex stainless steel, the uniSTOR 180 comes with a 2-year parts and labour guarantee and a 25-year cylinder shell guarantee, offering long-term peace of mind and reliable performance.
