The Greenstar Heatslave 18/25 is part of a market-leading range of energy-saving condensing oil-fired boilers from Worcester combi series. 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 help to cut heating and hot water bills by between 5-10%. The Greenstar Heatslave 18/25 is appropriate for a small to medium sized, 1 bathroom apartment, house or bungalow. The Greenstar Heatslave 18/25 is ideal for replacing an existing boiler located in a utility room, garage or kitchen.
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.
