Product Description

Designed and manufactured by Baxi, the 624 is a condensing system gas boiler with a central heating output rating of 24 kW.

How efficient is the Baxi 624?

This is a highly efficient system boiler that could help to lower your heating bills thanks to 93% efficiency and an ErP A-rating.

Is the output rating suitable for my home?

The 624 has a central heating output rating of 24 kW which is well suited to properties with as many as 15 radiators.

Are there any other options in the Baxi 600 range?

In addition to this 24 kW model, there are also 15 kW and 18 kW system boilers available in the Baxi 600 range. Should a system boiler not be suitable for your home then combi and regular units are available too.

Is a system boiler suitable for my home?

System boilers must be installed alongside a hot water cylinder which is where domestic hot water is stored. This allows a system boiler to meet higher hot water demands than a combi boiler which is great for properties with 2 or more bathrooms.

How long is the warranty period?

Baxi 600 system boilers come with a 7 year warranty which will see that you’re well covered after the installation.

What are the key features of the Baxi 624?

The Baxi 624 is a UK-built boiler made with only top quality parts to deliver reliable and efficient performance. Plus, compact dimensions and a low lift weight make installation more straightforward, which could help to lower the costs.

If you live off-grid then an LPG version of this boiler is available.

How big is the Baxi 624?

Compact dimensions of 700x370x285mm (HxWxD) allow for wall-mounted installation within a kitchen cupboard.

All Baxi 600 system boilers have been certified to run on a hydrogen blend of 20%.
