Product Description

The 424 Heat boiler is a condensing regular gas boiler manufactured by Baxi and desigend for wall-mounted installation.

How efficient is the Baxi 424 Heat?

As is common with Baxi boilers, this is a highly efficient boiler that delivers efficiencies of 93%. It has also received an ErP A-rating for heat.

Is the output rating suitable for my home?

A central heating output rating of 24 kW makes the boiler an ideal option for home with around 15 radiators.

Are there any other options in the Baxi 400 Heat range?

Should this 24 kW model be too powerful then 12 kW, 15 kW and 18 kW models are all available in the Baxi 400 Heat range too. There’s also a more powerful boiler in the form of the 430 Heat which delivers an output of 30 kW.

Is a regular boiler suitable for my home?

Regular boilers heat your central heating system directly and also produces hot water for your cylinder.

Being a regular boiler you will of course need a hot water cylinder making this boiler type not suitable for smaller properties with no loft space.

How long is the warranty period?

All Baxi 400 Heat boilers are covered by a 5 year warranty as standard.

What are the key features of the Baxi 424 Heat?

The 424 Heat only weighs 19.5kg – which is the lightest boiler in the UK. Why does this matter? It makes for much faster installation which could save you money.

As with all Baxi’s in this range, it comes with an easy-to-fit wall mounted bracket – most installers are very familiar with this bracket type. This boiler does not require a pump overrun or even a permanent live – again, making for a fast and neat install.

How big is the Baxi 424 Heat?

The Baxi 424 Heat has dimensions of 625x370x270mm (HxWxD) which makes it compact and able to fit within a wall-mounted kitchen cupboard.
