Worcester Bosch Greenstar boilers
The Greenstar range from Worcester Bosch is an award-winning range of oil-powered, gas-powered, and LPG-powered boilers. Each boiler in the series is either “A” or “B” rated by the Energy Saving Trust. During their design and construction, real attention has been paid to efficiency (bringing your utility bills down) and efficacy of operation (providing you with the hot water and heating you want when you want it).
As you’d expect from a world-class manufacturer, each model is thoroughly and rigorously tested before it arrives with the installer.
Output rates
In this article, we’ll list all the current Worcester Bosch’s Greenstar boilers across their combi, system, and regular ranges. Next to each model and model number, you’ll notice an output figure. The output figure refers to the amount of water that your boiler can heat at any one time.
When speaking to a potential installer, he or she will ask you how often you use your hot water taps and when. Using this information, they will be able to calculate the optimal output range of your proposed boiler installation.
Efficiency rates
The efficiency rating you see next to each boiler is shown in two different ways – with a percentage figure and with a rating. The percentage figure tells you how much of the power your boiler draws is actually used on providing you with hot water and central heating. The higher the energy efficiency percentage, the lower your energy bills will be.
The Energy Saving Trust rates all boilers with a 90% efficiency with an “A” grade and between 86-90% with a “B” grade.
What will your installer recommend for your property?
When deciding on your installer, you must go for a company that is authorised and regulated. The boiler your installer will recommend will depend on the size of your home and how much demand you’ll have for hot water at the same time.
As a rule of thumb, your installer will make their suggestion to you based upon the following table:
Where do you live? | Bedrooms | Bathrooms | Radiators | Boiler size | Ideal boiler type |
---|---|---|---|---|---|
• Mid-terrace house • Small bungalow • Apartment |
Up to 2 | 1 | 10 | 24kW-27kW | Combi |
• Larger terrace • Medium bungalow • Medium semi |
3+ | 1-2 | 15 | 28-34kW | Combi |
• Larger semi • Large detached |
4+ | 2+ | 20 | 34-42kW | Combi or Conventional |

Worcester Bosch FAQ
Worcester Bosch boiler warranties
Each of the boilers listed on this page comes with a warranty lasting between 2 and 5 years. A warranty offers you peace of mind that, should a fault develop with your boiler within the warranty period, that Worcester Bosch will resolve the problem for you free of charge.
Check with your installer whether your warranty covers parts, labour, or both. When you do get your boiler serviced, make sure that the person servicing your boiler is a registered Gas Safe expert. Please note that most warranties require you to carry out a servicing once a year during the warranty period and that failure to do so will invalidate the warranty.
Worcester Bosch boiler repairs
Only Gas Safe registered experts are allowed by law to maintain, service, or install boilers so please do not attempt to repair your boiler yourself. Please call Worcester Bosch, your installation engineer, or your maintenance engineer for advice.
Worcester Bosch boiler heating controls
Worcester Bosch has embraced digital and mobile technology to help its customers better and more easily control their boilers. Once your system is installed, you can download the Bosch EasyControl app from the App Store or Google Play – it works like a smart thermostat. If this is not of interest to you and you’d prefer the standard manual controls, please let your installer know.
Worcester Bosch boiler error codes
In the same way as with your car, your Worcester Bosch boiler system can tell you when something is wrong with it. It does so by displaying a code which your engineer will know how to interpret. The information your boiler displays will then be used by your engineer as part of a proven troubleshooting approach to determine what he or she needs to do to return the boiler to full working order.
Please contact your installation engineer or your maintenance engineer if your Worcester Bosch boiler displays a code that you don’t know the meaning of.
Worcester Bosch boiler and renewable heating
With many of the current Greenstar boilers, your installer can connect them to Greenskies Solar Panels (also manufactured by Worcester Bosch). These solar panels and solar thermal collectors use energy from the sun to heat the water in your boiler. Ask your installer for more information.
