The new Worcester Greenstar 30i NG Combi Boiler has been developed to take the place of the award-winning and popular Greenstar i Junior. It maintains and improves on all the great features that have meant more than one million homes use this particular type of combi boiler.

If your home is small to medium-sized with just one bathroom, you can enjoy the benefits of upgrading your boiler to this one, which offers an output of 30kW.

This  appliance has been designed with your needs in mind, as the well-known manufacturer Worcester has created this new model based on feedback gathered from the engineers working in your home. And the role of installing this series of boilers has become even easier, as a result of the extremely lightweight product that comes with a pre-assembled wall frame and simple switch mounting points that make the process a breeze.

The Worcester Greenstar 30i NG Combi Boiler has been improved to offer increased hot water flow rates of up to 12.3 litres/min, which is great news for families in busy homes that require instant hot water throughout the day.

When you choose this combi boiler, there is no need to worry about figuring out how to set the programme, as the control panel is designed to be simple and extremely easy to use.

This is a reliable appliance that provides assurance during the colder months, thanks to the CondenseSure system, which eliminates the risk of burst and frozen pipes when the temperature drops below zero.

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 6 years*

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