Baxi 424 Heat Only Boiler Pros and Cons
The Baxi 424 heat only boiler brings an impressive mix of benefits and limitations worth considering before making your purchase.
You'll love that it's incredibly lightweight at just 19.5kg – making it the easiest boiler to install in the UK. Its compact size means it'll fit neatly into your standard kitchen cupboards, and with 93% efficiency, it'll help keep those energy bills in check. Plus, you're covered with a solid 5-year warranty.
However, it's not all smooth sailing. If you're in a smaller property without loft space, this mightn't be your best choice.
You'll need a separate hot water cylinder, and with its 24kW output limit, larger homes might find it underpowered. It also won't work with LPG fuel, so keep that in mind if you're off the gas grid.
How Does The Baxi 424 Heat Only Boiler Compare To Similar Models From Other Manufacturers?
Comparing the Baxi 424 to its main competitors reveals some interesting trade-offs worth evaluating for your home heating needs.
At 93% efficiency, the Baxi 424 runs slightly behind the Vaillant ecoTEC Plus and Worcester Bosch Greenstar's 94% rating. However, it makes up for this with its lightweight design at just 19.5kg, making it significantly easier to install than the 25.2kg Worcester Bosch.
While you'll pay less upfront for the Baxi 424, you might want to review Worcester Bosch's longer warranty of up to 10 years compared to Baxi's 5-year coverage.
The Vaillant sits comfortably in the middle price range and matches most of the Baxi's specs.
If you're working with a tighter budget and prioritise easy installation, the Baxi 424 could be your best choice.
