The Greenstar 12i System is part of a market-leading range of energy-saving condensing gas-fired boilers from Worcester System series boilers. Greenstar 12i System boilers can cut hot water and heating bills up to 20% - and they?re up to 30% cheaper in maintanance than an older boiler. Up to 97% of the gas consumed by a new Greenstar 24i condensing System Boiler is converted into heat for the heating of the system.
Greenstar 12i is easy to carry and install.Greenstar condensing boilers deliver this energy-saving performance by recycling exhaust gases to extract and re-use latent heat - a highly efficient use of energy which also significantly reduces carbon dioxide in the atmosphere.
