Worcester Greenstar 8000+ 35kW System Boiler

The Worcester Greenstar 8000+ 35kW System Boiler is a powerful, high-efficiency heating solution designed for medium to large homes with higher heating and hot water demands. As part of Worcester Bosch’s premium Greenstar 8000+ range, it combines outstanding performance with modern styling, quiet operation and advanced control options. Because it's a system boiler, it works alongside a separate hot water cylinder but doesn’t require a cold-water tank in the loft. This makes installation more flexible while still providing strong mains-pressure hot water to taps and showers. With condensing technology, an A-rated efficiency label and compatibility with smart thermostats, this boiler is designed to deliver comfort, convenience and long-term energy savings.
