Worcester Bosh Greenstar Intelligent Filling System 7738112911

Intelligent software ensures the Greenstar 8000 Lifestyle range of boilers maintain optimum pressure. If the system pressure becomes low the software allows the internal filling valve to automatically fill the heating system. Once optimum pressure has been reached, this function will automatically stop and close the integrated filling valve. Also prevents the boiler from over-filling and will alert the customer if the heating system is losing too much pressure, reducing the need for unnecessary call-out... - Manufacturers part number: 106HP
