Perfect for homes of any size, the Worcester Bosch Greenstar 8000 Style Combi is a powerful wall hung gas condensing boiler.
The Greenstar 8000 Style Combi is a design-led boiler that features innovative new technology to optimise heating and hot water performance. It can run on a 20% hydrogen blend and is available in either high gloss black or white to suit your home and taste. Worcester Bosch says this combi is one of its most powerful and connected wall-hung boilers yet, with the power to efficiently heat larger homes with two or more bathrooms.
How Much Does this Boiler Cost?
This top of the range combi boiler from Worcester Bosch comes in 30kW, 35kW, 40kW, 45kW and 50kW outputs and will set you back anything between £1,133 and £2,265, not including installation. Combi boiler installation costs vary significantly, depending on the installer and how much work is involved. We recommend getting a fixed-price quote from different local and national installers to find the best price for this combi boiler plus installation.
How will I know if this Boiler is Suitable for My Home?
Combi or combination boilers take water directly from the mains and produce hot water on demand without needing tanks in the loft of a separate cylinder, making them ideal for homes where space is limited. The Worcester Bosch Greenstar 8000 Style Combi comes in a range of outputs up to 50kW to suit almost any domestic heating requirement and comfortably heat larger homes with multiple bathrooms.
We understand how difficult it can be to know which boiler type and size to choose, so we suggest you ask a Gas Safe registered engineer to visit you in your home so they can recommend a boiler based on your requirements.
Is it a High Efficiency Boiler?
Yes. The Worcester Bosch Greenstar 8000 Style Combi is 94% efficient and has an A energy efficiency rating. You can even purchase optional smart heating controls to optimise the performance of this combi boiler, reduce energy wastage and maximise efficiency.
Does this Boiler have a Good Range of Controls and Features?
It certainly does. This attractive combi boiler has an easy-to-use full-colour touchscreen display panel and is compatible with a range of optional controls, including the wireless Bosch EasyControl that connects to your smartphone and lets you control your heating and hot water from anywhere. It is one of Worcester Bosch’s quietest boilers to date and is available in high gloss black or white to suit your home. The Greenstar 8000 Style Combi also features innovative new technology, such as the optional Intelligent Filling System that constantly monitors the boiler’s pressure and automatically refills the system if it drops to save you from having to top it up yourself.
How long is the Warranty on this Boiler?
The guarantee on Worcester Bosch Greenstar boilers starts from 5 years. However, this can be extended to 12 years when you choose a Worcester Bosch Accredited Installer to install the boiler and opt for a Greenstar filter system.
