View Large ImagePowerful enough to generate heat and hot water for homes with up to two bathrooms, the Worcester Bosch Greenstar Heatslave II External 18/25 condensing combi boiler is kept out of sight and out of mind in the garden or garage. A green powder-coated casing helps the Heatslave II to unobtrusively blend into the garden while frost proofing makes sure it runs and runs even during the very coldest months. With impressive flow rates and a fuel bill-beating ErP A rating for heating efficiency, along with the option to run alongside eco-friendly energy sources such as solar panels, it's easy to see why the Heatslave is currently the UK's preferred external oil fired combi boiler.
