Product Description

The Greenstar 28i Junior has been discontinued.

The Greenstar 28i Junior is a highly reliable condensing combi gas boiler that has been designed and manufactured by Worcester Bosch.

Which boiler replaced the Greenstar 28i Junior?

This boiler has been replaced by the Greenstar 30i combi gas boiler.

What output rating does this boiler feature?

This boiler has an output rating of 28kW, making it suitable for medium sized homes that don’t have such an excessive need for heating and hot water.

How efficient is this boiler?

Greenstar 28i Junior boilers have an efficiency of 89.10% (SEDBUK) making them A-rated for heat. They’re also A-rated for hot water too thanks to the high flow rate of 11 litres per minute.

Will this boiler save me money?

The Worcester Bosch Greenstar 28i Junior can reduce domestic hot water and heating bills by up to 20%, as well as reduce the amount of carbon dioxide and nitrogen oxide pollutants released into the atmosphere.

Thanks to being compact, this boiler is easy to install which will help to save you time and money on the installation costs.

What features come with this boiler?

The Worcester-Bosch Greenstar 28i Junior employs a heat cell constructed from cast aluminium and silicon with a large surface area so that more heat from flue gases can be extracted, making the boiler more efficient overall.

Is a combi boiler suitable for my home?

A combi boiler supplies hot water and heating on demand by using the mains water supply. This means you don’t need to have bulky tanks or cylinder, perfect for smaller homes where space is limited

Does this range of boilers come with any options?

A 24 kW model is also available, which is better suited to slightly smaller homes than the 28 kW. This boiler also comes with the option of being a natural gas boiler or an LPG unit.

Where can this boiler be placed?

With this being a wall mounted compact unit, it’s able to save you some much needed space around the home as it can fit in a standard cupboard.

A mounting frame with pipes to the rear means that no pipe work needs to remain exposed following installation. The multi-directional 100mm or 125mm flue systems can run horizontally or vertically including 45' or 90' bends for flexibility.

How long is the warranty?

As standard, Greenstar 28i Junior boilers come with a 2 year warranty, with the option to upgrade to 10 years if installed by a Worcester Accredited installer.

* This is a guide price for a straightforward, like-for-like boiler replacement. Installation costs will vary dependent on work required.
