Worcester Greenstar Si Condensing Combi Boilers

Worcester’s market-leading combination boiler series has been developed to provide the high level of heating and hot water comfort you come to expect from a company which is part of the renowned Bosch Group. At the heart of every Greenstar si Combi boiler is the WB3 cast aluminium silicon heat exchanger, which has been installed in over 3/4 million boilers since its introduction in 2004.

It is this incredibly efficient unit that is responsible for converting 97% of the gas consumed by a Greenstar Si condensing combi boiler into heat for the heating and hot water system. In comparison, older, non-condensing boilers achieve only around 78% efficiency, resulting in higher heating and hot water bills.

Hence SEDBUK Band A ratings for all models in the new Greenstar Si condensing combi range.

A condensing boiler is more efficient due to its ability to extract more heat from the flue gases normally lost to the environment through the flue system.

All the Greenstar Si boiler models use the same WB3 aluminiumsilicon heat cell. Worcester’s heat exchanger has been designed to optimise clean burning combustion over an extra large surface area. Each heat cell is factory set and 100% tested so, as long as the gas inlet pressure is correct, commissioning couldn’t be any easier. The heat exchanger requires minimal servicing which means fewer spare parts during its lifetime. The heat cell can be cleaned in situ via an inspection hatch saving time during service.

Worcester Greenstar CDi condensing combi boilers

The Greenstar CDi boiler series is part of a market leading range of energy-saving condensing wall mounted gas-fired combi boilers which is very good news for the environment and excellent news for specifiers, developers, installers and consumers alike.

Higher efficiency therefore highly cost effective The Greenstar CDi condensing combi 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 boilers achieve around 78% efficiency. Therefore, compared with a non-condensing boiler, Greenstar CDi condensing combi 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 Greenstar CDi condensing range.

Greenstar CDi condensing combi boilers deliver this energysaving 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.
