The Baxi 624 24kW Gas Combi 2 Boiler is a compact, wall-mounted natural gas combination boiler designed to provide central heating and domestic hot water from a single appliance. With a 24kW heat output, 10.2 L/min domestic hot water flow rate and ErP A rating, it is a practical choice for homes requiring an efficient and space-saving combi boiler.
The compact 395mm wide × 700mm high × 285mm deep casing is designed to fit inside a standard 290mm-deep kitchen cupboard, making the Baxi 624 suitable for installations where available space is limited. Built-in pipework within the boiler casing also helps create a neat installation.
For convenient system maintenance, the boiler features an Easy-Fill permanent filling link, allowing system pressure to be topped up without requiring an engineer visit. A pre-heated siphonic condensate trap helps reduce the risk of condensate pipes freezing during colder weather.
The Baxi 624 is compatible with the Baxi uSense smart heating control, while OpenTherm certification supports advanced heating control with compatible systems. It can also operate with natural gas or LPG without requiring a conversion kit and is certified for use with 20% hydrogen.
