The Baxi 600 range has 3 combi boilers with outputs ranging from 24kW to 36kW for hot water. The Baxi 636 combi boiler is the most powerful in its range with an output of 26.4kW for central heating and 36.8kW for hot water, meaning this combi boiler is powerful enough to heat a property with up to 20 radiators and one to two bathrooms. Meanwhile, many homes do not require this output for heating and hot water. In this case, the Baxi 624 or the Baxi 630 may be better suited to your home.
Combi boilers are ideal for properties where space is limited, this is because they combine both the water heater and the central heating into one single unit. This combi boiler has been designed to be compact and lightweight so that it can be installed neatly into the space of a standard kitchen cupboard. They also remove any need for additional hot water or cold water storage tanks that you would typically need with a regular or system boiler.
