Baxi 824 24kw 800 Combi 2 Boiler Only  7814304

Compact and easy to use, the Baxi 800 Combi 2 has a Ten-year parts and labour warranty. When you need to top off the pressure, the Easy-Fill permanent filling link makes it simple to do so without involving an engineer. As well as this, Baxi uSense smart controls can also be used with this boiler, which would be operated by a smartphone or tablet.

The boiler also features a preheated condensate trap, which will prevent freezing in winter, meaning no more frozen pipes during the winter months. It is also compatible with natural gas or LPG without the need for a conversion kit. As well as this, the Baxi 800 combi 2 is also very reliable and energy efficient, featuring an impressive "A" energy rating.

Known for its practicality, the compact boiler will fit into most cupboards with ease and is incredibly easy to install thanks to the simple hanging bracket. The boiler also features a brass hydraulic block and a built in stand off frame.
