    • The Reliance Water Controls (RWC) Aquasystem ARB12 is a high-performance, 12-litre potable water expansion vessel specifically engineered for unvented hot water systems. Its primary function is to safely accommodate the natural thermal expansion of water as it heats up within a cylinder or sealed system (for instance, water heating from 0°C to 100°C increases in volume by approximately 4.5%). By absorbing this extra volume, the vessel prevents dangerous pressure spikes and protects system components from premature wear.

      • Accommodates hot water expansion from unvented cylinders
      • Includes wall mounting bracket
