If you are one of the people who did, you can be sure it is due to Worcester’s fantastic reputation for manufacturing some of the best domestic gas combi boilers on the market for years.

The Worcester Bosch 2000 is their first budget combi boiler so let’s see what makes this combi boiler a great choice.  

Is the Worcester Greenstar 2000 Combi Boiler Any Good? 

Worcester Bosch has been winning Which? Awards for best boiler manufacturer for over 10 years, so there were high expectations for the new Greenstar 2000!

This budget combi boiler has exceeded these expectations, becoming the preferred energy-efficient replacement boiler for smaller homes in the UK.

Worcester Greenstar 2000 Range & Outputs

The Worcester Greenstar 2000 is available in natural gas and LPG with two outputs only— 25kW and 30kW. 

The 25kW model is perfect boiler replacement for small to medium-sized homes, including flats, with one bathroom.

The 30kW model, on the other hand, can cope with higher hot water demands, so it’s suited for small to medium-sized homes with 1-2 bathrooms.

It also has a higher flow rate—12 l/min compared to the 25kw version’s 10 l/min.

Worcester Bosch Greenstar 2000 Combi Boiler Features

Quiet Mark Accredited

The Worcester 2000 combi has been given the Quiet Mark accreditation due to its low operating noise. Running at just 43 decibels, it’s one of the quietest combi boilers on the market.

Quick Tap Water-Saving Function

If you’re on a water meter, this clever feature will help you save water. Instead of running the tap while waiting for the water to warm up, simply open and quickly close your hot water tap, and the boiler will heat up the water faster than usual. 

Worcester 2000 Thermostats and Heating Controls

The Worcester Bosch 2000 is compatible with several digital and smart controls from Worcester’s range that make it super-convenient to control your boiler and the temperature of your home. 

If you have a universal thermostat such as Hive or Nest, you can also use these.

Let’s give you a quick overview of the range of thermostats and controls you can choose from.

Greenstar Comfort+ II RF 

This thermostat enables you to adjust the temperature of the rooms in your home at 6 different points in the day and the temperature of the hot water at 3 different points in the day.

With an easy-to-use menu and navigation, this is a simple yet effective way of controlling the temperature of your home all day long.

Greenstar Comfort+ Stat RF Thermostat

This is a wireless room thermostat that can be easily added to your current 230v timer. It comes with a “plug & play” key receiver for easier installation and features a single set point for temperature control. 

You can also make use of the load compensation feature, which saves energy by automatically adjusting the temperature output of your boiler to match your home’s heating requirements.

Bosch EasyControl Smart Thermostat 

Smart thermostats are a great way to control your heating from anywhere using your mobile phone.

If the temperature drops while you’re at work and you fancy a warm home to come home to, you can simply turn on your boiler remotely. You can also check your energy usage and control the heating in separate rooms. A fantastic way to save money on your gas and electricity bills.

Is the Worcester 2000 combi boiler hydrogen ready?

No, the Worcester Greenstar 2000 is not “hydrogen-blend ready”, although the entire range used to be marketed as such. In fact, after being accused of using misleading marketing practices, in 2024, the brand reached a formal agreement with UK regulators in which they committed to do better.   

Worcester Bosch 2000 Combi Boiler Warranty

The Greenstar 2000 comes with a 5-year warranty, which is not as good as the 10-year boiler warranties you get with some of the other models in the Worcester Bosch Greenstar range (check out best boiler warranties for more info). However, it can be extended to 7 years if you get any Greenstar System Filter installed when you purchase your new boiler. 

For your warranty to remain valid, you will need to make sure that your new boiler is installed by a Worcester Bosch accredited installer and serviced by a Worcester-approved engineer at least every year.

Worcester Bosch Greenstar 2000 combi boiler cost

By now, you’re probably wondering, how much do new boilers cost? The Worcester 2000 is one of the lowest-priced boilers on the market, even with installation included. This price covers all parts, labour, and the warranty.

Boiler Manufacturer	Boiler Cost	Boiler Cost With Installation
Worcester Bosch Greenstar 2000 25kw	£714	£1,795
Worcester Bosch Greenstar 2000 30kw	£838	£1,845

Worcester Bosch Greenstar 2000 Pros and Cons

Let’s have a look at the pros and cons of this Greenstar model from Bosch.

Pros: Reasons to buy this combi boiler

• Compact design: As a combi boiler, the Greenstar 2000 doesn’t have a separate hot water tank, making it ideal for homes with limited space. At just 400mm wide and 300mm deep, it can easily be installed in a small kitchen or utility room.
• Quiet operation: As the quietest boiler in Worcester’s range with a Quiet Mark accreditation, it’s suitable to be installed near living areas.
• Energy-efficient: The boiler runs at 93% boiler efficiency, so it doesn’t use excessive amounts of natural gas when it’s in use, which will help keep running costs and utility bills down.
• Easy installation: the installation process is straightforward and often requires minimal alterations and pipework. Always ensure that any new Worcester 2000 boiler installation you have is installed by a Gas Safe registered installer. Remember to factor installation into your new boiler replacement cost.

Cons:

• Limited capacity: It’s not suitable for larger homes with multiple bathrooms and high hot water demands.
• Relatively short warranty: The Greenstar 2000 comes with a 5-year warranty, which is shorter compared to other similar boilers on the market. For around £200 more, you could get the Worcester 4000 combi boiler, which comes with up to 12 years of warranty.

Which Worcester Bosch 2000 Is Best For My Home?

The Worcester 2000 combi is designed to be suitable for most small to medium-sized homes in the UK.

Worcester 2000 30kw gas combi boiler

The Worcester 2000 30kw is the better of the two in terms of power and keeping up with hot water demand—and it gives you a flow rate of 12 l/min. It’s suitable for small homes with one bathroom and shower room.

Worcester 2000 25kw gas combi boiler

The Worcester 2000 25kw combi is also designed for smaller homes with one bathroom. It has a more modest flow rate than the 30kw—10 l/min, but it’s more economical.

As it runs on a lower output, it uses less gas than the 30kw.

Final Verdict

Worcester Bosch Greenstar 2000 offers great value for money and years of reliable heating.

We love the fact that it comes at such a good price. The cost of a new boiler is around £760, and you can get the boiler installed for around £1,800.

A Worcester Bosch model that’s quiet, compact, and reliable—what more could you ask for at a great price? 

The Greenstar 2000 shouldn’t be confused with your average cheap boiler, but it’s also worth mentioning that it’s not anything like its bigger brother, the Worcester Bosch Greenstar 8000 lifestyle range.

This is a far superior boiler but comes at a far superior price. It may look the same, which adds to the 2000’s credentials, but that’s where a lot of the similarities stop. If you’re looking for this kind of powerhouse boiler, you can read a review on the Worcester Bosch Greenstar 8000 here.
