Worcester Bosch Greenstar 2000
The Greenstar 2000 is Worcester’s great-value combi. It is small enough to sit between standard kitchen wall cupboards, so it is a neat swap for an older combi, and it runs quietly. It only comes as a combi, so it is best for homes where one shower or tap is usually running at a time.
Worcester Bosch Greenstar 4000
The Greenstar 4000 is the all-rounder of the range. You get quiet running, a full colour display that is easy to read, and a longer guarantee than the 2000. It comes as a combi or a system boiler, so it suits most family homes, including those with a hot water cylinder.
Worcester Bosch Greenstar 8000
The Greenstar 8000 is Worcester’s premium range, with the most powerful wall-hung combis they make. It comes in combi, system and heat only versions, so it can be matched to almost any home, and it carries the longest guarantee of the three.

Frequently asked questions
Is the Worcester Bosch 8000 worth the extra over the 4000?
If you have a bigger home or more than one bathroom, the extra power and the longer 12 year guarantee usually make the 8000 worth it. For most family homes with one main bathroom, the 4000 does the job well for less.
Does the Greenstar 2000 come as a system boiler?
No, the Greenstar 2000 is a combi only. If you need a system or heat only boiler, look at the 4000 or 8000.
How long is the guarantee on a Worcester Bosch boiler?
When we fit it, you get 6 years on the Greenstar 2000, 10 years on the 4000 and 12 years on the 8000, as long as the boiler is serviced every year.
Which Worcester Bosch boiler is best for a flat?
The Greenstar 2000 is usually the best fit for a flat. It is compact, quiet and designed for homes with one bathroom.
