The Worcester Bosch Greenstar 8000 Life Combi is the direct replacement for the CDi Classic with upgraded controls and wireless connectivity.
Available in five sizes and with a generous guarantee, the Worcester Bosch Greenstar 8000 Life Combi is ideal if you live in a larger property with more than one bathroom. It’s a wall-hung gas condensing combi boiler that keeps all of the best CDi Classic boiler features but has a modern new design and a whole host of additional benefits to make it easy for you to look after your home’s heating and hot water.
How Much Does this Boiler Cost?
The Worcester Bosch Greenstar 8000 Life Combi comes in 30kW, 35kW, 40kW, 45kW and 50kW outputs and will cost you anything from £1,200 to £2,070, not including installation. Combi boiler installation prices differ depending on the installer and the amount of work involved, so it pays to look around and compare quotes. We recommend getting a fixed-price quote from as many local and national installers as possible so that you can find the best price. Also, you must make sure you choose a Gas Safe registered installer to fit your new combi boiler.
How will I know if this Boiler is Suitable for My Home?
Combi or combination boilers heat water directly from the mains when you turn on a tap, meaning they don’t require tanks in the loft or a hot water storage cylinder. That makes the Worcester Bosch Greenstar 8000 Life Combi suitable for homes where space is limited. This boiler comes in a range of outputs to suit most heating requirements and is ideal for larger homes with more than one bathroom.
Boilers are expensive, so it’s really important to ensure you select the right size for your home. You can ask a trusted Gas Safe engineer to visit you in your home to recommend the correct boiler type and size based on your heating and hot water requirements.
Is it a High Efficiency Boiler?
Worcester Bosch’s Greenstar 8000 Life Combi is 94% efficient for heat and hot water and holds an A energy efficiency rating. Although highly efficient straight out of the box, efficiency levels can be improved when you use optional controls, such as the wireless EasyControl room thermostat to control your heating and hot water.
Does this Boiler have a Good Range of Controls and Features?
Yep. The Worcester Bosch Greenstar 8000 Life Combi has a display screen and easy-to-use push control buttons and is even wirelessly compatible with the Bosch EasyControl to allow you to control your heating and hot water from your smartphone. It includes an optional Intelligent Filling System that monitors the boiler’s pressure and automatically adjusts it when needed to save you from topping it up yourself. This powerful combi boiler is also very quiet and can run on a mixture of hydrogen and natural gas.
How long is the Warranty on this Boiler?
The Worcester Bosch Greenstar 8000 Life Combi comes with a 5-year warranty as standard. You should receive a 12-year guarantee if the boiler is installed with a Greenstar system filter and by a Worcester Bosch Accredited Installer.
