The Worcester Greenstar 38CDi Classic NG Combi Boiler is an exceptional, high-performance combi boiler that sits among the top of the range in the Greenstar range. This accolade ensures it sets a benchmark for improved energy efficiency in the industry.

This excellent and reliable appliance is the ideal solution for medium or large properties and works where there are only one or two bathrooms. This model offers a range of fantastic features, but also an output of 30kW, which places it as the highest domestic hot water flow rate within the Greenstar combi range.

This appliance is well known for its reliability and superior performance, so you can trust it during the winter months when the temperature drops outside. One of the impressive features is the CondenseSure siphon, which eliminates the risk of your central heating pipes freezing or bursting.

You can trust this boiler to maintain a constant ambient temperature within your home and offer reassurance during the winter.

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.
