The Baxi 636 36kW Gas Combi 2 Boiler is a compact, wall-mounted combination boiler designed to provide central heating and domestic hot water from a single appliance. With a 36kW heat output, 15 L/min domestic hot water flow rate and ErP A rating, it is well suited to homes requiring higher hot water performance.
Its compact 395mm wide × 700mm high × 285mm deep design allows the boiler to fit inside a standard kitchen cupboard, including installations where space is limited. At just 30kg, the Baxi 636 is also designed for straightforward handling during installation.
The boiler is compatible with the Baxi uSense smart heating control, allowing compatible heating and hot water controls to be managed remotely. An Easy-Fill permanent filling link makes it easier to top up system pressure, while the pre-heated siphonic condensate trap helps protect against condensate pipe freezing during colder weather.
The Baxi 636 can operate with natural gas or LPG without requiring a conversion kit and is certified for use with a 20% hydrogen blend. It also features OpenTherm certification, a built-in stand-off frame and a simple hanging bracket for installation flexibility.
