The Worcester Bosch Greenstar 4000 30kW is a wall mounted gas fired condensing combi boiler designed for medium sized properties. 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, quieter operation, and enhanced user interface.
The combi 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. It features a modulation range from 3kW to 24kW for heating, ensuring efficient energy use. The unit is ErP A-rated with 94% efficiency and is compatible with a 20% hydrogen blend. An aluminium heat exchanger ensures effective heat transfer and durability.
Compact dimensions (724mm × 400mm × 310mm), Quiet Mark accreditation (around 42dB), and a full colour text display make it suitable for discreet installation and easy operation. Additional features include Quick Tap water saving technology, integrated condensate siphon for frost protection, and compatibility with Bosch EasyControl smart systems.
