Product Description

The Greenstar 30i is a wall-mounted condensing system gas boiler by Worcester Bosch.

How efficient is the Greenstar 30i?

An efficiency of 92% makes this an ErP A-rated boiler that could help to lower your heating bills. This is because it’s able to produce more heat using less fuel than an older boiler.

Is the output rating suitable for my home?

A 30 kW output rating makes this a powerful system boiler suitable for installation in properties with around 20 radiators.

Are any other options available in the Greenstar 30i range?

If the 30 kW output of this boiler is too powerful for your heating demands then models with outputs ranging from as low as 9 kW to 27 kW are also available.

Is a system boiler suitable for my home?

A system boiler needs to be installed alongside a hot water cylinder. This is where domestic hot water is stored meaning that they can meet higher demands than a combi boiler (which doesn’t have a cylinder).

How long is the warranty period?

When installed by a Worcester accredited installer, the Greenstar 30i comes with a warranty of up to 7 years.

What are the key features of the Greenstar 30i?

The Greenstar comes with many advantages such as easy to use controls as well as a wide range of control choices, helping you to use the boiler to its full advantage and ensuring you are more comfortable in your home. It boasts a display with information that is clear and easy to read.

This is a suitable boiler for homes where the heating system includes a hot water storage cylinder. This unit also comes with a low energy pump, helping to reduce the electrical usage. It also comes equipped with a large condensesure style siphon built into the boiler to protect it from any sort of frost risk.

How big is the Greenstar 30i?

Designed for installation within a standard kitchen cupboard, the Greenstar 30i measures 690 x 390 x 280mm (HxWxD).
