Higher efficiency and highly cost effective. Up to an incredible 97% of the gas consumed by a new Greenstar Si condensing combi boiler is converted into heat for the heating and/or hot water system.
Other types of boiler achieve around 80% efficiency. Therefore, compared with a new conventional combi boiler, a Greenstar Si can cut heating and hot water bills by between 15-20% - and it’s up to 30% cheaper to run than an older boiler.
