The Greenstar 2000 Combi is Worcester Bosch’s quietest and lowest priced combi boiler, suitable for small and medium-sized homes.
When you choose the Greenstar 2000 Combi for your home, you get Bosch engineered quality at an affordable price.

And, like Worcester Bosch’s entire gas boiler range, this compact combi boiler can run on a 20% hydrogen blend.
How Much Does this Boiler Cost?
Available with outputs of 25kW and 30kW, the Worcester Bosch Greenstar 2000 Combi is a price-competitive boiler with a price tag between £735 and £852, including VAT. You also need to spend money on the installation, which must be carried out by a Gas Safe registered engineer. Combi boiler installation costs can vary significantly, so we recommend getting a quote from as many local and national installers as possible to find the best price. Always request a fixed-price quote for the boiler plus installation.
How will I know if this Boiler is Suitable for My Home?
The Worcester Bosch Greenstar 2000 Combi is ideal for apartments, small homes and medium homes with one bathroom and properties where space is limited. Like all other combi boilers, this combination boiler heats water directly from the mains whenever you turn on a tap, meaning it doesn’t require tanks in the loft or a hot water storage cylinder in the airing cupboard.
Choosing the right combi boiler size is crucial to ensuring your home remains comfortable and you don’t spend more money than is necessary on your heating bills. If you’re thinking about having a new combi boiler installed, you should ask a qualified heating engineer to visit you in your home to advise you on the type and size of boiler you need.
Is it a High Efficiency Boiler?
This affordable combi boiler from Worcester Bosch runs at 93% efficiency and is A-rated for both heat and hot water, so it should help reduce your carbon footprint and keep running costs and bills down.
Does this Boiler have a Good Range of Controls and Features?
The Greenstar 2000 Combi is the quietest combi boiler available from Worcester Bosch and is Quiet Mark certified. It will fit between most wall-mounted kitchen cupboards and features an innovative Quick Tap water-saving function, which reduces water wastage and activates with a quick open and close of a hot tap. This compact combi boiler is also compatible with a range of wireless thermostats, including the Bosch EasyControl that lets you control your heating via an app on your smartphone.
How long is the Warranty on this Boiler?
Worcester Bosch’s Greenstar 2000 Combi comes with a 5-year warranty as standard or a 6-year warranty when installed with a Greenstar System Filter.
