Worcester-Bosch Greenstar 28i Junior

The Greenstar 28i Junior from Worcester-Bosch is a compact condensing boiler available in natural gas and LPG ("Liquified Petroleum Gas") models. The Worcester-Bosch Greenstar 28i Junior employs a heat cell – constructed from cast aluminium and silicon – with a large surface area such that more heat from flue gases can be extracted and the boiler is more efficient overall. Indeed the Worcester-Bosch Greenstar 28i Junior can reduce domestic hot water and heating bills by up to 20% as well as reducing the amounts of carbon dioxide and nitrogen oxide pollutants released into the atmosphere.

The compact dimensions and light weight of the Worcester-Bosch Greenstar 28i Junior means that it can be lifted and installed by one person. A mounting frame with pipes to the rear means that no pipe work needs to remain exposed following installation and multi-directional, 100mm or 125mm, flue systems can be run horizontally or vertically – including 45° or 90° bends – for flexibility.
