Worcester Greenstar 8000+ System Boiler - 30kW

Worcester Bosch offers a standard warranty, with an extended guarantee of up to 12 years available when installed by an accredited installer and fitted with a Greenstar System Filter.

The 30kW output is generally suitable for medium to large homes with higher hot water demands or multiple bathrooms. Its compatibility with both Natural Gas and LPG makes it versatile.

The boiler features a full-colour display with touch controls for direct operation. It is also compatible with Worcester Bosch wireless control systems for remote and smart home integration.

The Greenstar 8000+ range is known for its high energy efficiency, designed to help reduce fuel consumption and lower energy bills. Specific ratings can be found in the product's technical documentation.

While designed for use with unvented cylinders and wireless controls, specific compatibility with solar thermal systems should be confirmed with your installer or Worcester Bosch technical support.

Annual servicing by a Gas Safe registered engineer is recommended to maintain performance, safety, and warranty validity.

Check the mains power supply, ensure the thermostat is calling for heat, and verify that the pressure gauge is within the recommended range (typically 1-1.5 bar when cold). If the issue persists, consult the user manual or contact a qualified engineer.

Ensure the system is adequately filled and check for any closed isolation valves. If using a wireless control, verify the settings are correct. For persistent issues, an inspection of the unvented cylinder and system components may be necessary.

Refer to the user manual for a specific breakdown of error codes. Common codes may indicate issues with ignition, water pressure, or sensor faults. Some codes may require professional diagnosis and repair.

Noises such as banging or whistling could indicate air in the system, low pressure, or a potential issue with the pump or heat exchanger. Bleed radiators to remove air and check system pressure. If noises continue, professional inspection is advised.
