The Worcester Bosch Greenstar 8000+ 40kW Heat Only Boiler is a wall mounted, gas fired condensing boiler designed for medium to large heating systems. As a heat only (regular) boiler, it requires a separate hot water cylinder and cold water storage tank, making it suitable for properties with multiple bathrooms and higher hot water demand.
This model delivers a central heating output of 40kW and operates on natural gas, with LPG compatibility available. It achieves an ErP A rating with a seasonal efficiency of 94%, meeting current energy standards. The boiler is also hydrogen ready for a 20% hydrogen blend, supporting future low carbon energy transitions.
Key features include a full colour touchscreen display, rear piping connections, and an Intelligent Filling System that automatically maintains system pressure. It supports smart thermostat connectivity for remote control and monitoring. The unit measures 780mm high, 440mm wide, and 365mm deep, with a lift weight of approximately 42kg.
- 40kW central heating output for larger home systems
- 94% efficiency and ErP A rating to reduce fuel use
- Aluminium silicon heat exchanger for long term performance
- Automatic filling maintains system pressure without manual input
- Rear piping and pre‑plumbing jig simplify installation
