The Worcester Bosch Greenstar 4000 30kW is a wall mounted gas fired condensing combi boiler designed for small to medium sized properties with higher hot water demand. It provides central heating and instantaneous hot water without requiring a separate cylinder or tank. This model builds on the Greenstar i-series with improved efficiency and user friendly features.
The boiler offers a domestic hot water output of 30kW and supports flow rates up to 12.3 litres per minute at a 35°C temperature rise, making it suitable for homes with one bathroom and occasional simultaneous hot water use.

It incorporates Quick Tap water saving technology, integrated condensate siphon for frost protection, and optional smart control connectivity via Bosch EasyControl.
