DISCONTINUED. Here we have the 128 Combi gas boiler from Baxi. This boiler is 89.1% efficient making it rated B for both heat and water. With the 128 you get an output of 28kW but it is also available in the 24kW (the 124) making this a perfect boiler for most homes.

The Baxi 128 is both compact and lightweight weighing just 32.5 kg so is able to fit inside a standard 30cm deep cupboard making this boiler perfect for those small properties with not much room.

This boiler is a simple yet reliable boiler. It comes with user friendly controls helping you to get to grips with your new boiler quicker. This boiler has easy access to all components for when it needs a service and also helps with installation too. The 128 is compatible with other Baxi products including:
