Worcester Greenstar 2000 25kW Combi Boiler & Horizontal Flue

The Worcester Greenstar 2000 25kW Combination Boiler & Horizontal Flue Pack is a compact, efficient and reliable gas combi boiler package designed for apartments, flats and small to medium-sized homes with one bathroom. Supplied with a compatible Worcester horizontal flue kit, this pack provides the main boiler and flue components required for a professional combi boiler installation.

The Greenstar 2000 25kW is one of Worcester Bosch’s most popular entry-level combi boilers, offering trusted Worcester reliability, compact dimensions and ErP A-rated efficiency. With a domestic hot water output of 25kW and central heating output of up to 20kW, it is ideal for homes with modest heating and hot water demand.
