Worcester Greenstar 4000 LPG Combi Boiler Overview
The Worcester Greenstar 4000 LPG combi boiler packs impressive performance into a sleek, modern design.
You'll appreciate its full-colour display and whisper-quiet operation that won't disturb your peaceful evening Netflix sessions.
Available in 25kW and 30kW outputs, this A-rated boiler is perfect for small to medium-sized homes with one bathroom.
It's got some clever features too, like a water-saving 'Quick Tap' function and wireless connectivity through the Bosch EasyControl system.
What's really neat is its wide modulation range, which means it'll efficiently heat your home whether you need a little warmth or full power.
Plus, it's hydrogen blend ready, so you're future-proofed for upcoming green energy developments.
The integrated condensate siphon helps prevent freezing in winter – a common headache for many homeowners.
Worcester Greenstar 4000 LPG Combi Boiler Performance and Efficiency
When it comes to performance and efficiency, Worcester's Greenstar 4000 LPG combi boiler really shines with its impressive 94% ErP rating. You'll appreciate how it modulates down to 3kW, meaning it'll only use the energy it needs – just like dimming your lights instead of having them full blast all the time.
| Feature | 25kW Model | 30kW Model |
|---|---|---|
| Hot Water Flow Rate | 9 l/min | 12.3 l/min |
| Heating Output | 24kW | 24kW |
| Noise Level | 45 dB(A) | 45 dB(A) |
The boiler's hot water performance won't disappoint either. Even with just 1 bar of water pressure, you'll get consistent flow rates. Plus, it's 10% quieter than its predecessor – so quiet you might forget it's running. The innovative 'Quick Tap' function helps save water, while the wide modulation range keeps your energy bills in check.
Worcester Greenstar 4000 LPG Combi Boiler Pros and Cons
Building on those impressive performance specs, let's weigh up what makes the Worcester Greenstar 4000 LPG combi boiler shine – and where it might fall short.
You'll love the A-rated 94% efficiency that'll keep your energy bills in check, while the whisper-quiet 45dB operation means you won't even know it's running. The smart home compatibility lets you control your heating from your phone – perfect for those "did I leave the heating on?" moments.
- High efficiency rating saves money on bills
- Ultra-quiet operation at just 45dB
- Smart home integration for remote control
- Water-saving 'Quick Tap' function
However, there are some trade-offs to contemplate. The initial cost is higher than budget alternatives, and you're limited to 25kW or 30kW outputs.
Plus, you'll need professional installation to maintain the warranty, and that aluminium heat exchanger isn't quite as robust as stainless steel options.
How Does The Worcester Greenstar 4000 LPG Combi Boiler Compare To Similar Models From Other Manufacturers?
Comparing LPG combi boilers head-to-head reveals some interesting insights about where the Worcester Greenstar 4000 stands among its rivals.
While it delivers solid A-rated efficiency like its competitors, you'll find the Greenstar 4000's warranty period falls a bit short. Viessmann offers 10 years on their heat exchanger, while Ideal and Baxi provide 7-year standard coverage compared to Worcester's 5 years.
Size-wise, the Greenstar 4000 isn't winning any slimming contests. At 724mm x 400mm x 310mm, it's bulkier than the compact Baxi 600 and Ideal Logic+.
It's also not the quietest kid on the block – operating at 45 dB compared to Viessmann's whisper-quiet 34 dB.
However, you'll get competitive hot water flow rates and mid-range pricing that make it a solid contender.
