What type of Worcester Bosch boiler do you need?
Get help understanding the advantages and disadvantages of the three main types of Worcester Bosch boilers and find the one that's right for your home.
Worcester Bosch combi boilers.
Great for smaller homes as they can fit in a cupboard and you don’t need a hot water cylinder or cold water storage tank, so they don't take up any loft space either.

Worcester Bosch regular boilers.
If you often use hot water in multiple places at the same time, consider a regular or condensing boiler, linked to a hot water cylinder and a cold water storage tank.

Get help with your Worcester Bosch boiler troubleshooting.
Having trouble with your water pressure? See an error code or fault code on your Worcester Bosch boiler? These fault codes generally begin with the letters EA and are displayed on the boiler’s digital interface. Here are what some of the error codes mean:
Fault code EA 229 - Blocked condensate pipe.
When the EA229 fault code is displayed, it means that the condensate pipe in your Worcester Bosch boiler is blocked. You’ll find a condensate pipe in any more condensing boilers and it’s used to transport waste.
Sometimes condensate pipes can freeze, which you can solve by pouring warm water over them or getting a Gas Safe engineer to help.
Fault code EA338 - Boiler leaking water.
If you see the fault code EA338 (or sometimes EA281), then you may have a hole in the pipework or a broken seal. You’ll need to call a Gas Safe engineer who will be able to tell you whether you need something repaired or a replacement part.
Fault code E5218 - Boiler overheating.
If you see the fault code E5218, E5332, E9219 or E9224 then it could be because your Worcester Bosch boiler is overheating. It could be due to a faulty central heating pump, blocked condensate pipe or problems with the heat exchanger.
You’ll need to call a Gas Safe professional to review and fix the problem.
If you see a different error code or want to troubleshoot an issue with your Greenstar boiler, Worcester Bosch offers an online troubleshooting tool as well as some handy Greenstar boiler checks you can do.
