Product Description

The Worcester Bosch Greenstar 2000 range of combi boilers have been designed to make the quality of their boilers an affordable option for more people.

How efficient is the Worcester Greenstar 2000 25?

This is a highly efficient heating system, as shown by the 93% efficiency rating, making it an ErP A-rated boiler. Plus, it can modulate its power output down to 4.8 kW to reduce energy usage. All of this can help to lower your heating bills.

Is the output rating suitable for my home?

As a combi, Greenstar 2000 boilers have a central heating (CH) output and a domestic hot water (DHW) output. The CH output is 20 kW while the DHW output is 25 kW, making this model well suited to properties with fewer than 10 radiators and a single bathroom.

Are any other options available in the Greenstar 2000 range?

If your property needs slightly more power on the domestic hot water side of things then there’s a second model in this range with a DHW output of 30 kW. The central heating output of this boiler is also 20 kW.

Is a combi boiler suitable for my home?

A combi boiler is the best option for small to medium-sized properties with 1-2 bathrooms (1 bathroom in the case of Greenstar 2000 boilers). They take up very little space and deliver hot water on demand rather than storing it in a cylinder.

How long is the warranty period?

As standard, the Greenstar 2000 comes with a 5 year warranty period. This can be extended to 6 years when fitted with a Greenstar System Filter.

What are the key features of the Greenstar 2000?

Greenstar 2000 boilers boast a number of features to make them high-quality despite the low price tag. Some of these features include the ability to condense in hot water mode, modulation down to 4.8 kW and a highly reliable C6 heat exchanger. It’s also the quietest combi boiler manufactured by Worcester Bosch.

How big is the Greenstar 2000 combi boiler?

This is a compact wall-mounted boiler with dimensions of only 724 x 400 x 300mm (HxWxD).
