The Greenstar condensing
regular boiler range
The Greenstar regular range is part of a market leading
range of energy-saving condensing wall mounted
gas-fired boilers.
Floor standing regular boilers are also available from
Worcester in 30kW and 40kW outputs. For further
information see the FS CDi Regular Tech & Spec,
part no. 8 716 115 422.
Higher efficiency therefore highly cost effective
The Greenstar condensing regular boilers have an annual
efficiency (SEDBUK value) of over 90%, efficiently
producing heat for your heating and/or hot water system.
Non-condensing boilers achieve around 78% efficiency.
Therefore, compared with a non-condensing boiler,
Greenstar condensing regular boilers can cut heating and
hot water bills and are cheaper to run than an older boiler.
Hence, SEDBUK Band A ratings for all models in the
Greenstar condensing range.
Greenstar condensing regular boilers deliver this energy-
saving performance by 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: renowned
Worcester quality and reliability; a range of outputs to
satisfy the heating demands of a range of households and
truly all-round value for money.
Greenstar 12Ri low NOx model
Worcester’s commitment to reduce emissions from gas-fired
condensing boilers now sees the 12Ri model achieve NOx
values <40mg/kWh. This enables the appliance to achieve
3 credits under The Code for Sustainable Homes whilst still
achieving a SEDBUK A rating.
