Pick up

Choosing the Worcester Greenstar 30CDi Classic NG System Boiler is the ideal solution for larger homes, typically those with three or more bedrooms.

It offers a 30kW output and is delivered with a steel wall-mounting jig, which means all necessary pipework can be installed before the boiler is fixed to the wall, saving time and money. What’s more, all the pipework is concealed behind the appliance to ensure a neat, sleek look within your home.

Save money on your fuel bills as a result of the efficient nature of this new system boiler, such as its ‘A’ rating for energy efficiency and high-performing features.

The Worcester Greenstar 30CDi Classic NG System Boiler also offers additional peace of mind during winter, as it comes with the CondenseSure system installed to eliminate the risk of pipes bursting when the temperature is freezing. And when the appliance is installed in a loft or garage, the frost protection reduces the risk of damage.

Trust this efficient and reliable new boiler to make managing the hot water and central heating within your home simple.

By fitting this boiler with the Greenstar System Filter, the standard 5 year warranty will increase to 7 years*

*Registration with Worcester Bosch is required to benefit from the additional warranty.
