The Greenstar Heatslave series is part of a market-leading range of energy-saving condensing oil-fired boilers from Worcester. At least 90% of the oil consumed by a Greenstar Heatslave condensing combi boiler is converted into heat for the heating and/or hot water system and they can cut heating and hot water bills by between 5-10%.
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.
This external boiler is ideal for situations where it is not feasible or desirable to have a boiler located within the property.
