Its main benefit is providing high-output, on-demand hot water and central heating efficiently, suitable for large homes, with user-friendly controls and reliable engineering.

Is this boiler suitable for a small apartment?

The 45kW model is typically recommended for larger properties with high heating and hot water demands. A smaller output model from the Greenstar range might be more appropriate for a small apartment.

How long is the warranty period?

When installed by a Worcester Bosch Accredited Installer along with a Greenstar System Filter, it comes with the longest guarantee, up to 12 years.

Do I need a separate hot water tank?

No, as a combi boiler, the Greenstar 8000+ provides both central heating and hot water directly, eliminating the need for a separate hot water tank.

What maintenance does it require?

Annual servicing by a qualified engineer is recommended to ensure optimal performance, efficiency, and safety. The boiler's display will show fault codes to aid technicians.

Can I control this boiler remotely?

Yes, the Greenstar 8000+ is compatible with Worcester controls and wireless systems, allowing for remote or smart home integration if the appropriate controls are installed.

What does the full-colour display show?

The full-colour display provides clear, text-based information about the boiler's status, settings, and any fault codes, with backlit touch buttons for easy navigation.

Troubleshooting

Boiler not firing up

Check if the thermostat is set correctly and powered on. Ensure the gas supply is active. If the issue persists, contact a qualified engineer.

Low hot water pressure or temperature

Verify that the hot water taps are fully open. Check the boiler's display for any error codes. Ensure the hot water output settings are correctly configured. If problems continue, a service check is recommended.

Boiler making unusual noises

Listen to the type of noise (e.g., banging, whistling). Some noises can indicate air in the system or a need for servicing. Contact an engineer for diagnosis.

Error code displayed

Refer to the user manual for the specific error code meaning. Many codes indicate a maintenance need or a simple reset procedure. If the code persists, contact a Worcester Bosch Accredited Installer.
