REACH OUT TO THE TEAM
The Greenstar 8000 ‘Style’ is not just a boiler; it is the most powerful, connected, and beautiful heating system Worcester Bosch has ever made.
Designed for larger Edinburgh homes with high hot water demand, the 8000 series replaces the legendary CDi Classic. If you have two bathrooms, a detached home in Corstorphine or The Grange, or simply want the best engineering money can buy, this is the boiler for you.
Why Choose The Greenstar 8000?
Standard boilers struggle to run two showers at once. The 8000 is built differently.
-
Unrivalled Hot Water Power: With output options up to 50kW, the 8000 is the most powerful wall-hung combi on the market. It delivers high flow rates that can fill a bath quickly, even if someone else is using the kitchen tap.
-
Stunning Design (Black or White): Boilers used to be ugly white metal boxes. The 8000 ‘Style’ features a high-gloss glass finish (available in black or white) and a full-colour touchscreen interface. It looks as good in a modern utility room as it does in a designer kitchen.
-
Intelligent Filling: Forget messing around with filling loops. The 8000 features the “Intelligent Filling System,” which monitors your system pressure and automatically tops it up if it drops too low.
The "12-Year Guarantee" Difference
Because Smart Gas Solutions is a Diamond-Level Accredited Installer, we can offer you the maximum 12-year guarantee on the Greenstar 8000.
-
Standard Warranty: 7 Years.
-
Smart Gas Warranty: 12 Years.
-
That is 5 extra years of peace of mind, covering parts and labour, just for choosing an accredited local expert.
Is The Greenstar 8000 Right For My Home?
We typically recommend the 8000 for:
-
Detached & Semi-Detached Homes: Properties with 3+ bedrooms.
-
Multiple Bathrooms: If you have an ensuite and a main bathroom, you need the 8000’s horsepower.
-
Garages & Utility Rooms: The robust casing and frost protection make it perfect for cooler installation spaces.

GREENSTAR 4000 BOILER FAQs
What is the lifespan of a Greenstar 4000 boiler?
Around 10 – 15 years on average. With a correct install, clean system water, and annual servicing, many Greenstar 4000 boilers run efficiently for longer. Replacing filters, checking inhibitor levels, and keeping flow temps sensible all help extend life.
Is the Worcester Bosch Greenstar 4000 a good boiler?
Yes—the Greenstar 4000 is widely regarded as a strong choice. It’s efficient and reliable, runs quietly, and its compact, modern design suits most homes. Compared with older models, it adds smarter controls and energy-saving modulation, making it an excellent all-round upgrade.
How many radiators can a Worcester 4000 run?
Roughly up to 15 average-sized radiators on the 30 kW Greenstar 4000, assuming a typical Edinburgh home and standard outputs per rad. The 25 kW version is usually comfortable up to 10 radiators. Exact numbers depend on heat loss, radiator sizes, and flow temperature.
What's the difference between 25kW and 30kW models?
The 30kW provides faster hot water delivery — filling a bath in approximately 8 minutes versus 10 minutes with the 25kW. The 25kW provides up to 24kW for central heating, while the 30kW also provides up to 24kW for central heating (both models modulate down to 3.0kW minimum). So the main difference is the supply of the hot water, bigger machine = faster output of hot water ✅ . They both provide the same output for the heating system.
