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. Thanks to its compact and lightweight design this combi boiler can be installed neatly into the space of a standard kitchen cupboard. Combi boilers also remove any need for additional hot water or cold water storage tanks that you would typically need with a regular or system boiler, helping you save space in your home.
There are 2 combi boilers in the Baxi 400 range, the 424 and the 428. This combi boiler, the 428 model has the same output of 21.8kW for central heating as the 424 however, has a higher output of 28kW for hot water, making it powerful enough to heat a medium-sized home with up to 15 radiators and a single main bathroom.
