The Baxi 800 836 36kW 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 36kW heat output, 15 L/min domestic hot water flow rate and ErP A rating, it is a strong option for homes requiring higher hot water performance.
Its compact 395mm wide × 700mm high × 285mm deep casing is designed to fit inside a standard kitchen cupboard, including cupboards around 290mm deep. The boiler weighs just 30.5kg and has built-in pipework within the casing to help make efficient use of installation space.
An Adey MagnaClean Micro2 system filter is included to help protect the boiler and central heating system from sludge and magnetic debris. The Baxi 800 836 also features a pre-heated siphonic condensate trap to help prevent condensate pipes from freezing during colder weather.
For convenient heating management, the boiler is compatible with the Baxi uSense smart heating control, allowing compatible heating and hot water settings to be controlled remotely. The Easy-Fill permanent filling link also makes it easier to top up system pressure without requiring an engineer visit.
The boiler is certified for use with 20% hydrogen and can operate on natural gas or LPG without requiring a conversion kit, providing installation flexibility across compatible fuel supplies.
