Specifications

Match the badge in front of you to a row before you use any of this. Every figure below was read from the Worcester Bosch literature listed under Sources at the foot of this page, checked 6 September 2026. Outputs, variants and part numbers change by year, so the appliance data plate is still the last word.

• These are the natural gas GC numbers printed in Worcester's own installation manuals. LPG versions carry their own number, so check the appliance type code on the badge before writing anything down.

Where the data plate is

Centrally on the bottom of the appliance, in line with the control panel. A second, shorter type plate sits in an easily accessible place on the outside of the case. One badge carries the model, the serial number and the GC number.

Worth knowing on site

• Designed to be simple and compact, fitting a standard kitchen cupboard.
• Available in combi and system configurations depending on output.

On the tools

Being the compact end of a widely fitted brand, the 2000 turns up most often on straightforward one-bathroom swaps where cupboard space is tight. Parts and know-how are rarely a problem given how common the wider Greenstar range is on UK vans and in merchants.

Variants and configuration

It is offered in combi and system form, so the same model name can describe two different installations. Because the 2000 sits at the narrower end of Worcester Bosch's output spread, always confirm the exact kW and configuration from the data plate rather than assuming from the badge alone.

Where it sits in the range

The 2000 sits at the entry point of the current Greenstar family, below the mid-range 4000 and the flagship 8000. It typically replaces older, smaller combis or first-generation condensing boilers in flats and starter homes rather than larger regular systems.

Finding the manual and the data plate

For the exact outputs, gas rate, dimensions and commissioning figures, work from the appliance’s data plate and the manufacturer’s installation and servicing instructions. The GC (Gas Council) number and serial are on the data plate, usually behind the front panel or on the underside. Worcester Boschpublishes its manuals and support at Worcester Bosch support.
