Worcester-Bosch continues to set the highest standards in home heating with the Greenstar 8000+ Range, designed to deliver premium performance with cutting-edge technology. The Greenstar 8000+ Range was launched in September 2024, replacing the 8000 Lifestyle range, and they are an incredibly popular boiler choice in U.K homes. Currently one of the most powerful wall-hung boiler available in today’s market, this beautiful new boiler is one that you would be proud to have on show in your kitchen. In fact, it was designed at a depth that would match a kitchen cupboard so you can proudly display your boiler and stir up a bit of boiler envy with visitors – for the first time in history.

The new Greenstar 8000+ range is available in 2 models, the 8000+ and the 8000+ Style and a wide range of output sizes capable of heating homes of any size. Its quiet operation and innovative new features really portray a modern-day appliance. This, together with its beautiful aesthetics make for a game-changing boiler. This range is not only powerful but also energy-efficient, helping homeowners reduce energy bills while maintaining optimal heating in your home.

Greenstar 8000+

The new Greenstar 8000+ range comes in 2 models. The first of these is the 8000+ model which builds upon the CDi Classic range but with a whole new design. It is wirelessly compatible with Worcester’s own smart control, the Bosch EasyControl.

Greenstar 8000+ Key Features

  • The 8000+ features a digital gauge on the boiler control display, allowing pressure monitoring even when the power is off. In contrast, the 8000 Life has an LCD display
  • Lesser weight than the famous Cdi Classic
  • The 8000+ includes an industry-first ‘RF Key’ receiver that links time and temperature controls to the boiler, making it easier to fit Greenstar Comfort+ II RF and Bosch EasyControl
  • The 8000+ has a large capacity trap that increases the volume of condensate discharge, reducing the risk of freezing
  • The 8000+ allows for draining down the boiler without connecting to an external drain-off hose, and the front access PRV can be removed in less than 10 minutes
  • The 8000+ incorporates a high-quality pressure sensor and pressure monitoring logic to ensure no disruption during installation and maintenance

8000+ also boasts new technology to ensure your system pressure is kept at its optimum level. By automatically maintaining optimal boiler pressure, this feature eliminates the need for manual adjustments, reducing the risk of breakdowns and prolonging boiler lifespan.

Greenstar 8000+ Style

While the model focuses on reliability and performance, the Style model takes it a step further with enhanced aesthetics and a full-colour touch display, making it the premium choice for modern homes. This design-driven boiler is packed with the latest technology to give you the very best performance in heating and hot water.

Greenstar 8000+ Style Key Features

  • Wireless connectivity with the Bosch EasyControl
  • Stunning design-led aesthetics
  • Precision engineering and industry-leading heating and hot water performance
  • Full-colour text display for simple diagnostics

The settings can be effortlessly adjusted to provide optimum heating and hot water comfort. The sleek display not only looks great but also simplifies troubleshooting with detailed error messages, reducing the need for unnecessary service calls.

What’s the difference between the 8000, 2000 and 4000?

We can see that the Worcester Bosch 8000 has a lot to offer. However, Worcester Bosch offers other boiler models that may be more suitable for your home. So let’s check them out.

Read the Worcester Bosch 2000 Boiler Review here

The Worcester Bosch 2000 series is ONLY available as a combi boiler, there are no system or regular versions of this boiler. It is designed to offer customers a more affordable version of the Worcester Bosch Life 8000 series by scaling down some of the non-essential features.

The 2000 series is also only available in a 25 & 30kW model, which is suitable for small and medium homes with one bathroom. If you have a large home with over 15 radiators or two bathrooms that will be used simultaneously, then the 2000 series probably won’t have the power you need for your system.

The Worcester Bosch 2000 series is the quietest boiler manufactured by Worcester Bosch with an ERP rating of 43dB, which is quiet for an appliance. So if the boiler is located in a living area such as the kitchen, then this is an excellent option. While ideal for small to medium-sized homes, the 2000 series may not be suitable for properties with multiple bathrooms or high simultaneous hot water usage.

As mentioned, the Worcester Bosch 2000 has been designed to be a more affordable, toned-down version of the 8000. As a result of this, the Greenstar 2000 is much cheaper. So how much more does the 8000 costs than the 2000 Series?

The Worcester 2000 Series 30kW with the same package costs £2,299 inc. VAT. The Worcester Bosch 8000+ Series 32kW costs £3109 inc. VAT. £810 more than the 2000 series, a clear difference of price. Even if purchased on Explore Boiler Finance Options here, that’s still a substantial increase.

Moreover, putting cost aside, it’s worth mentioning here that the 2000 Series comes with a 5-year guarantee and the 8000 Series comes with a 10-year guarantee with WarmZilla, so you also get an added five years of peace of mind on the 8000 series.

Read the Worcester Bosch Greenstar 4000 Boiler Review here

Worcester Bosch has released the 4000 on May 17th 2021. Since its release, the Greenstar 4000 has gained popularity for its ease of installation and impressive performance.

Available as both a combi boiler and a system boiler, this brand new boiler is the big brother to the Greenstar i range. This means you are getting all the great features and benefits of the Worcester Bosch Greenstar, but with a little added spice.

Based on the design of the famous, best-selling boiler on the market, the Worcester Bosch Greenstar i, Worcester Bosch have created a new and improved version, raising the bar with ease and speed of installation, commissioning and servicing. The exterior of the 4000 series is very similar to that of the Worcester Bosch 8000+ boiler (though the 8000+ Style is different) , but is significantly cheaper.

The Worcester Bosch 4000 will be available as a combi boiler with outputs of 25kW and 30kW available with a flow rate of up to 12.3 l/min, and a system boiler in 12kW, 15kW, 18kW, 21kW and 24kW.

Below is a comparison table of the Worcester Bosch Greenstar 8000+ 30kW, the Greenstar 2000 30kW and the newest edition, the Greenstar 4000 30kW (using only the information available for all three, for a fair comparison) so that we can how each boiler model performs and help you decide which is better for your home. Please note that more information about the Greenstar 4000 is to follow once it is released.

Whilst the 8000+ Range is £810 more expensive based on a direct 30kW comparison with the Greenstar 2000, you do actually get a fair bit more performance for your money. However, when comparing the 8000+ 30kW to the Greenstar 4000 30kW, the differences become less significant.

It is evident from reviewing the comparison table that the Worcester Bosch 8000+ smashes it out the park when it comes to its guarantee, with 12 years guarantee for extra peace of mind. However, the Greenstar 4000 is not far behind, with 7 years.

The Greenstar 4000 and 2000 are similar in size, whereas the 4000 is significantly smaller than the 8000+, better suited for smaller homes and easier to install in a standard kitchen cupboard. When comparing all three boiler models, it looks like the new Greenstar 4000 could become the perfect boiler choice, offering the power of the 8000 but in the same compact size as the 2000.

Meanwhile, the 2000 series is a great entry-level boiler, priced to compete with mid-range boilers while giving you the reliability and aftercare that Worcester is famous for – the Worcester Bosch Greenstar 2000 offers exceptional value for money.
