Baxi 824 24Kw 800 System 2 Boiler Only Inc Adey Magnaclean Micro2 7814314

When you require a lot of hot water or have multiple bathrooms, the Baxi 800 System 2 boiler is the best choice. It has a ten-year parts and labour warranty and is compatible with Baxi cylinders and the Megaflo Eco line. When it comes to topping off 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 System 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.

The Adey Micro 2 Filter is also included with this boiler. This filter will provide protection from magnetic and non-magnetic debris and will allow your boiler to have a much longer lifespan and to keep operating optimally and efficiently.
