The Vaillant Unistor 300 litre indirect heat pump cylinder is manufactured from hardwearing stainless steel and incorporates the latest thermal-injected insulation for ultra-low heat loss, as little as 1 k W in 24 hours. The Unistor has a large-diameter, smooth-surfaced coil positioned in an ideal location for maximum hot water performance. The best part is that automatic de-scaling ensures ongoing efficiency with minimal maintenance.
