In 2014 and for the fourth year running the entire range of Worcester Greenstar gas boilers have been awarded Which? Best Buy.

Greenstar CDi Classic gas combi boilers are our top of the range boilers and have the ability to condense in both heating and hot water modes.

With high domestic hot water outputs of 29kW, 34kW, 38kW and 42kW, and following on from your feedback, the CDi Classic now includes a larger condensate siphon to reduce the risk of frozen condensate and a paper wall mounting template to aid installation.

More new features include an in-built Keyless Filling Link to make system re-pressurisation easier. The pump has been upgraded to a low energy model which meets the future ErP legislation requirements.
