Upgrade your home’s heating and hot water with the Worcester Bosch Greenstar 4000 30kW Combi Gas Boiler, a modern, efficient and compact solution designed for small to medium-sized homes with one bathroom. As the direct successor to the popular Greenstar 30i, this natural gas combi boiler combines dependable performance with smart features designed to improve everyday comfort and efficiency.
With an ErP A rating and wide modulation range, the Greenstar 4000 can adjust its output according to heating demand, helping to optimise gas consumption. The innovative Quick Tap water-saving function can also help reduce unnecessary water usage, while instantaneous hot water means there’s no need for a separate hot water cylinder.
The boiler features a modern design with an intuitive full-colour text display, making everyday controls simple to understand. Its low noise operation makes it particularly suitable for homes where the boiler is installed close to living areas, while strong performance in low water pressure conditions helps provide comfortable hot water when you need it.
For additional convenience, the Greenstar 4000 supports wireless connectivity with Bosch EasyControl, giving homeowners greater flexibility over their heating controls.
