Worcester Greenstar Style 45kW Combi Black LPG

The Worcester Bosch Greenstar 8000 Style 45kW Combi Black LPG boiler combines exceptional performance, contemporary design, and cutting-edge technology. Designed for larger homes with high hot water demand, this powerful combi boiler delivers superior comfort, energy efficiency, and effortless control — all wrapped in a sleek, modern black finish.

Powerful and Efficient Heating Performance

With a domestic hot water output of 45kW and a flow rate of 18.3 litres per minute, the Greenstar Style 45kW LPG model is ideal for properties with multiple bathrooms and high heating requirements. It’s built to deliver consistent water pressure, rapid heating, and excellent energy efficiency — earning an ErP A rating for both heating and hot water. Thanks to NOx Class 2 low-emission technology, this boiler also reduces environmental impact without compromising performance.

Innovative Design and Smart Technology

The Greenstar Style range represents the next generation of Worcester Bosch boilers. It introduces the Greenstar Intelligent Filling System, which automatically maintains system pressure — eliminating the need for manual refilling. The boiler is also compatible with Worcester Bosch Comfort II controls and EasyControl smart thermostats, allowing you to adjust your heating remotely for maximum efficiency and convenience. Its steel-reinforced front cover can be removed with just one screw, giving quick and easy access for servicing and maintenance, while the quiet 53dB operation ensures minimal household disruption.

Installer-Friendly and Easy to Maintain

Designed with both homeowners and installers in mind, the Greenstar Style 45kW LPG features enhanced touchpoints that simplify installation and servicing. Pipe connections, flue points, and fixing positions are identical to the Greenstar CDi Classic, making upgrades straightforward. With improved accessibility and smart internal layout, this boiler helps reduce installation time and ongoing maintenance costs.

Stylish and Contemporary Finish

The high-gloss black design of the Greenstar 8000 Style makes it as attractive as it is powerful. Its modern, minimalist aesthetic fits seamlessly into contemporary interiors, making it suitable for visible installation in kitchens or utility areas.
