• Worcester Bosch Greenstar Heatslave II 18/25kW ErP Combi Oil Boiler - 7731600261

The Worcester Bosch Greenstar Heatslave II 18/25kW ErP oil combi boiler is an internal boiler features 2 water modes: Standard and Eco. In the Standard mode, the burner operates quickest to retain the high thermal store temperature, maximising hot water. In Eco mode, the thermal store temperature can fall more before the burner fires, preserving fuel.

Intelligent Pull-Out Interface

One of the standout features of this boiler is the pull-out interface that allows you to precisely adjust the heating and hot water as standard. This design also allows you to use the Comfort or Intelligent controls, helping to save energy and enhance the use of additional accessories, such as weather compensation.

You'll also get peace of mind when storing this boiler around children, thanks to the concealed controls, so little fingers can't make adjustments.

Energy Saving

This boiler is built to preserve energy, cut energy costs and increase comfort. This is possible thanks to the 'keep hot' function, which ensures hot water is available almost instantly, and the Heatslave II's built-in thermal store ensures the boiler provides instant hot water for long periods.
