Product Description

The Worcester Bosch Greenstar 18Ri is a highly reliable condensing regular gas boiler that’s ideal for homes with a lower demand for heating.

How efficient is this boiler?

A seasonal efficiency rating of 92% and ErP A-rating for heat makes the Greenstar 18Ri a highly efficient unit.

Is the output rating suitable for my home?

The output rating of 18 kW is ideal for homes with 1 bathroom and a low heating and hot water demand but being a regular boiler might not make it an ideal choice for smaller properties.

Is a regular boiler right for my home?

Regular boilers directly heat the central heating system and also produce hot water for a cylinder. As a hot water cylinder is needed, often fed by a cold water storage cistern in the attic, regular boilers aren’t suitable for smaller properties.

Are any other options available in the range?

As well as this 18 kW model, the Greenstar range also includes boilers with many other outputs: 9 kW, 12 kW, 15 kW, 21 kW and 24 kW. The 9 kW, 12 kW and 15 kW models are all suitable for smaller homes with 1 bathroom that don’t have a high demand for heating and hot water. Meanwhile, the 18 kW, 21 kW and 24 kWunits can meet the heating and hot water demands of medium-sized homes.

How long is the warranty period?

Available with a 5 year warranty as standard, that can be extended to 10 years when installed by a Worcester Accredited installer, you’ll be well covered by Worcester Bosch.

What are the key features of the Greenstar 18Ri?

Greenstar Ri boilers include frost protection, a simple boiler control for maximum control and full compatibility with Worcester Greenskies solar panels.

How big is the Greenstar 18Ri?

As a wall-mounted compact boiler, the 18Ri can be installed within a standard cupboard to save space around the home. This is thanks to dimensions of only 600 x 390 x 270mm (HxWxD).
