Product Description

The Baxi 624 is a condensing combi gas boiler designed for wall-mounted installation within a kitchen cupboard.

How efficient is the Baxi 624?

Installing a Baxi 624 combi boiler could help to lower your heating bills as it performs to highly efficient levels. It has a seasonal space heating efficiency of 93% and ErP A-rating for heating and hot water.

Is the output rating suitable for my home?

A central heating output of 21.2 kW and domestic hot water output of 25.8 kW means that the Baxi 624 is well suited to properties with no more than 10 radiators and a single bathroom.

Are any other options available in the Baxi 600 range?

There are 3 combi boilers in the Baxi 600 range and this, the Baxi 624 is the least powerful. In addition to this model is the 630 and 636 – both of which have higher domestic hot water outputs.

Should your property have higher demand for hot water with multiple bathrooms then the Baxi 600 range also includes system and regular boilers which both store hot water in a cylinder.

Is a combi boiler suitable for my home?

A combi boiler is a great option for small-medium sized properties as they deliver central heating and hot water on demand as and when needed. This is opposed to system and regular boilers that store hot water in a cylinder, allowing them to meet higher demand. Not needing a cylinder is one of the benefits of a combi boiler as it means that they don’t take up as much space.

All Baxi 600 boilers have a lengthy 7 year parts and labour warranty attached to them.

What are the key features of the Baxi 624?

The pipes are within the boiler casing keeping all the mess out of sight and it has an easy-fill permanent filling link making it easier for the system to be topped up.
