Are you wondering how the Baxi 624 compact combi compares to the likes of the Worcester Bosch 25si compact?
If you’re looking for the perfect compact boiler for your small apartment or home, then either of these two compact boilers may be just the ticket. But how can you tell which to buy?
Well, as an experienced engineer, I’ve used my know-how to take a closer look at these boilers. And below, I’m going to tell you more about how the 624 compares to the 25si, and which might be best for your home.
Introduction
The Baxi 624 is a great, energy efficient little option that’s been endorsed by the Energy Saving Trust. And, as you may know, 24/25kW and 30kW combis are the most popular of all boilers being sold at the moment. So, they’ve wisely updated their range to include a compact model.
It’s also worth noting they have award-winning customer support, and have added plain English to their warranty – along with a jargon-buster on their website! This is very cool, as not everyone knows their unvented system from their sealed system right off the bat.
But this is a tricky one for me, as I’m comparing it to one of my favourite models of Worcester Bosch (Which ‘Best Buy’) boilers ever!
Both are a good, compact size, and they’re both easy to install. But there are some key differences (which I’ll tell you more about below). The most interesting one is that most manufacturers always give around 24kW to the heating circuit. Which, in most cases, is over-the-top for small homes and apartments.
So, Baxi may have done a bit of research and realised they can fill a bit of a gap in the market, there!
Output and flow rate
The Worcester Bosch 25si supplies an output of 24kW to your central heating. This is perfect for heating a small to medium-sized property with around 5 – 9 radiators. With a flow rate of 10.2 litres to your taps (with a 25kW output), it’s more suited if you have more showers than baths (the latter will be slow to fill).
In contrast, the Baxi 624 supplies an output of just 21kW to your central heating. This is more suited to a small home or apartment with 2 – 4 radiators. However, the flow rate is the same as the Worcester Bosch, coming in at 10.2 litres (a 25kW central heating output).
So, what this really boils down to is your home’s central heating demand. And whether you may be looking at making any home improvements (like an extension) in the near future. If your home has 5 – 9 radiators, and you’re mainly using a shower rather than a bath (and you need a compact boiler), I’d opt for the 25si.
However, if you have a small apartment with just 2 – 4 radiators, you could save quite a bit on the Baxi 624.
Size and special features
You’ll be pleased to know both of these models are compact. This is perfect if you really need to make the most of space in your home. The 25si and the 624 use minimal space and will easily fit in your kitchen cupboard or Edinburgh press that’s 290mm deep.
And because both are combi boilers, you won’t have to worry about any tanks taking up extra space! The 25si is fully compatible with Worcester Bosch’s Wave control system, whereas the 624 can be used with Baxi’s new uSense controls.
Guarantee
Now, this is where things start to get more interesting. Worcester Bosch is currently the proud owner of absolute best no-quibble boiler guarantee on the market, and with the 25si, you’ll be covered for a grand total of 9 years (when fitted with the brand’s own filer and controls). This is a popular option for my customers, especially since Worcester Bosch boilers tend to last longer than other brands.
In comparison, the Baxi 624 only offers a 7-year guarantee. This is still a good, reliable guarantee – you won’t find any catches in the small print. And unlike the Worcester Bosch 25si, you won’t have to pay extra for the filter and controls in order to get this great 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
I hope you’ve enjoyed reading. Both of these boilers have identical hot water outputs, so the most important thing to pay attention to here is the heating output. There’s no point in overspecifying for your home (unless you’re planning to add another bathroom or an extension). So, if you have less than five radiators, opting for the Baxi 624 compact combi may be the way to go.
It could also save you a few hundred pounds – which you could use to invest in Baxi’s new uSense system.
However, if you aren’t sure, I’d always recommend asking your chosen heating engineer for advice. And getting 2 – 3 fixed price quotes! Do you have any questions about these two boilers? Just let me know in the comments. I’ll be happy to help!
