Have you heard about the Worcester Greenstar 8000?

The mighty and super stylish Worcester Greenstar 8000 is not only available in an ultra powerful 50kw model which makes it ideal for larger properties, it’s also streamlined, available in black or white and has a high tech, user friendly display and and smart technology.

This state-of-the-art boiler is also perfect for creating a cascade heating system – and as Worcester Bosch accredited installers we can supply, install and maintain your Greenstar 8000 for you.

Worcester-Bosch Boiler 12 year Guarantee

As well as providing the extra power that you need to ensure the radiators and hot water throughout the house are piping hot whenever needed, a cascade ensures that if one of the boilers ever breaks down or develops a fault, there’s always a back up boiler (or two) keeping everything ticking over.

The Worcester 8000 Greenstar range goes up to 50kW, but we can install two in tandem, giving you 100kW and a back up boiler. It also offers a fantastic 12 year parts and labour guarantee, so once your heating system is up and running you can relax. In the unlikely event of a breakdown, we’ll be on hand to get everything up and running again in no time.
