The Baxi 424 24kW Combi 2.1 Gas Boiler is a compact, wall-mounted combination boiler designed to provide central heating and domestic hot water on demand. With a 24kW heat output and ErP A rating, it offers an efficient heating solution for homes using either natural gas or LPG.
The compact design measures 395mm wide × 700mm high, making it suitable for installations where space is limited. Baxi’s 400 Combi range is designed to fit into a 290mm-deep cupboard, while its lightweight construction helps make installation and handling more straightforward.
The Baxi 424 features a stainless steel heat exchanger, brass hydraulic components and an external analogue pressure gauge. A pre-heated siphonic condensate trap helps with condensate management, while the boiler is compatible with smart heating controls including the Baxi uSense 2 Smart Room Thermostat.
The boiler can be manually converted between natural gas and LPG without an additional conversion kit, making it a flexible option for properties with or without a mains gas connection. It also features quiet operation and a user-friendly interface.
