Are you struggling to decide between the Baxi 630 compact combi and the Worcester Bosch 30si compact?
If you’re in need of a reliable, compact combi boiler with great flow rates for your apartment or small home, then either of these two combis might seem like a great idea.
So, how can you tell which might be the best fit for your home?
Well, as an experienced engineer, I wanted to help you out by taking a closer look at these two boilers. There are some key differences you should watch out for, so I’ll talk you through how to find out which might be best for your home.
Introduction
The Baxi 630 is an incredibly energy efficient model that’s been endorsed by the Energy Saving Trust. But I’m also a huge fan of the Worcester Bosch 30si (Which ‘Best Buy’) which is super reliable and comes with a great guarantee – however, it’s also a few hundred pounds more expensive than the Baxi.
Both of these boilers will help you make the most out of the available space in your home. However, there are some points you need to consider when picking the right one for you. So, let’s get started, shall we?
Output and flow rate
With an output of 24kW to your central heating, the Worcester Bosch 30si is great for heating a small to medium-sized property with around 5 – 9 radiators. This is more than you’d get with the Baxi 630, which supplies just 21kW to your central heating – and is more suited to an apartment or small home with 2 – 6 radiators.
Baxi have been quite clever when targeting smaller homes that want more in terms of hot water demand. Despite its smaller central heating output, the 630 offers just as much power as the Worcester Bosch 30si in terms of hot water – with both providing a flow rate of 12.2 and 12.3 litres per minute. It’s too close to call!
So, if your home has 2 – 6 radiators, but you want a great flow rate that will fill a bath or high pressure shower no problem, I’d opt for the Baxi 630. However, if you have 5 – 9 radiators, you might be better off going for the Worcester Bosch.
Size and special features
Good news! Both of these models are compact, which means they’ll easily fit inside a kitchen cupboard 290mm deep. The Worcester Bosch measures in at 700mm x 395mm x 280mm, whereas the Baxi is pretty similar at 700mm x 390mm x 285mm.
And because both are combi boilers, you won’t have to worry about any tanks taking up extra space! Both the Baxi and Worcester Bosch are also fully compatible with smart controls that can be operated anywhere, any time from your smartphone or tablet (as long as you have an internet connection!).
Guarantee
Let’s not forget one of the most important factors here; the guarantee. Worcester Bosch is currently a market leader, providing the best no-quibble boiler guarantee on the market. You can expect 9 years of coverage if you buy the 30si (when fitted with the brand’s own filer and controls). Worcester Bosch boilers also tend to last longer than other brands.
As for the Baxi 630, you can expect a 7-year guarantee. It’s also no-quibble, so you won’t be caught out by any small print. And unlike the Worcester Bosch 30si, you won’t have to pay extra for the filter and controls in order to get this fab deal.
TIP: Your guarantee will remain valid for this time as long as your boiler is serviced annually by a Gas Safe registered engineer.
Conclusion
Thanks for reading. If you’re still struggling about which boiler to buy – the Baxi 630 vs the Worcester Bosch 30si – I’d speak to your chosen engineer for advice. And don’t forget to get 2 – 3 fixed price quotes! The main difference between these two boilers is the heating output. So, unless you’re planning on adding an extension, you should choose the one most suited to how many radiators you have.
If you have less than five radiators, opting for the Baxi 630 compact combi could be your best choice. It could also save you a few hundred pounds – which you could use to invest in Baxi’s new uSense system.
However, don’t just take my word for it! Get an engineer to measure your home’s heat loss, so you can be sure. Do you have any questions about these two boilers? Just let me know in the comments. I’ll be happy to help!
