The old Greenstar i Series

Prior to the introduction of the Greenstar 4000, Worcester’s most popular combi boiler was the Greenstar i. The Greenstar i is no longer in production, but there are still some in the supply chain.

The Greenstar i was a very popular boiler because it suited small to medium sized homes with one bathroom; and the controls were straightforward.

Worcester Bosch describes the 4000 as being ‘instantly familiar and yet totally transformed’; since it was built on the old tried and tested model.

The 4000 is an improvement on the i in terms of the speed and ease of installation; commissioning and servicing; alongside improvements in efficiency and control.

What are the improvements with the Worcester Bosch Greenstar 4000?

Let’s look at why the 4000 is better than its predecessor…
