It’s often said that you can’t please everybody all of the time – but
the advanced new series of Greenstar CDi Conventional and system
condensing boilers from Worcester has so much to offer that it’s already
disproving such a notion.
Here is a ground-breaking range of energy-saving boilers which is very
good news for the environment and excellent news for specifiers,
developers, installers and consumers alike.
HE stands for Higher
Efficiency and for
Highly Cost Effective
The Greenstar CDi condensing
boilers have an average annual
efficiency (SEDBUK value) of
over 90%, efficiently producing
heat for your heating and/or hot
water system. Other types of
boiler achieve around 78% efficiency. Therefore, compared with a new
conventional boiler, Greenstar CDi condensing boilers can cut heating and
hot water bills and it’s cheaper to run than an older boiler.
Hence SEDBUK Band A ratings for all models in the new Greenstar CDi
condensing range.
Greenstar CDi condensing boilers deliver this energy-saving performance
by ingeniously recycling exhaust gases to extract and re-use the latent
heat – a highly efficient use of energy which also significantly reduces
carbon dioxide emissions into the atmosphere.
To all these major benefits you can add yet more: superlative Worcester
quality and reliability; a range of outputs to satisfy the heating demands of
a range of households; and truly exceptional all-round value for money.
