Our new, industry first, Greenstar Intelligent Filling System uses the latest innovative software to ensure the Greenstar 8000 Lifestyle range helps maintain optimum boiler pressure. If the system pressure becomes low, this revolutionary 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. The Greenstar Intelligent Filling System also prevents the boiler from over-filling and will alert your customer if the heating system is losing too much pressure. This reduces the need or unnecessary call outs.
