Pick up
Choosing the Worcester Greenstar 40CDi Classic NG Regular Boiler with a 40kW output is the perfect choice for larger homes with more than three bedrooms available. 
This model is delivered complete with a steel wall-mounting jig. This means your central heating engineer can pre-install any necessary pipework before mounting the boiler to the wall, which saves valuable time and money. Afterwards, all the pipework is neatly stowed behind the appliance to create a neat finish within your home. 
The high output capacity within this regular boiler means hot water is replenished quickly throughout your home to each sink and bathroom, which is great news for busy families who put significant demands on their hot water and central heating system.
Introducing a new boiler means you are likely to enjoy reduced fuel bills as a result of the energy efficient nature of the new system. The Worcester Greenstar 40CDi Classic NG Regular Boiler is rated ‘A’ for energy efficiency, which places at the top end of the scale for efficiency and high-performance features. 
You can also enjoy extra peace of mind throughout the cold winter months, as this boiler is installed with the innovative CondenseSure system. This great feature eliminates the risk of your pipes freezing or bursting when the temperature drops below zero degrees. What’s more, you can confidently have this regular boiler installed wherever it suits you, even in a cold garage or loft, as the internal frost protection reduces the risk of the appliance being damaged due to frost and freezing temperatures. 
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.
