On the tools
As the flagship Greenstar, the 8000 is the one engineers reach for when a property has multiple bathrooms or high simultaneous hot-water demand. Its smart-thermostat compatibility means installs often involve more time discussing controls with the customer than a straight like-for-like swap.
Variants and configuration
Uniquely among the Greenstar family covered here, the 8000 comes in combi, system and regular form, including Worcester Bosch's most powerful gas combi. That spread means confirming the exact configuration from the data plate matters even more than usual before ordering parts.
Where it sits in the range
The 8000 sits above both the 2000 and 4000 as Worcester Bosch's premium Greenstar tier, aimed at larger, busier households. It is the natural upgrade path when a smaller combi in the range can no longer meet a growing home's hot-water demand.
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.
