Product Description

The Greenstar 30i is a highly reliable condensing combi gas boiler, designed and manufactured by Worcester Bosch that comes with a variety of features and benefits.

Why install a Greenstar I combi

The Greenstar I combi boiler is one of Worcester Bosch’s most popular combi boilers as it features instant hot water and can fill a standard kitchen sink in only 45 seconds.

What sort of home is this boiler suitable for?

An output rating of 30 kW makes the Greenstar 30i the perfect choice for larger homes with 2 or more bathrooms and a higher demand for heating and hot water.

What is the efficiency rating of this boiler?

This unit features an ErP (Energy Related Product directive) rating of A for both heat and hot water, thanks to its high heating efficiency of 94% and flow rate of up to 12.3 litres a minute. When installed with a Wave Smart thermostat, the Greenstar 30i can achieve an A+ ErP rating.

Is the output going to suit my home?

This unit features an 30kW output rating. Meaning it is suitable for those larger homes with more than one bathrooms and a higher demand for heating and hot water.

Is a combi boiler suitable for my home?

Combi boilers are great for smaller homes or properties where space may be limited as they don’t require an external water tank or cylinder. Instead, everything is wrapped up into a single cost-effective unit.

What features does this unit have?

Worcester Bosch have included many features and benefits within the Greenstar 30i, including simple boiler control with clear information to give you maximum control over the unit, a condensate discharge resilient to freezing up to -15°C, a low energy pump to reduce electrical usage, frost protection as standard – so you can be sure your boiler won’t let you down in the cold winter months – and also features a choice of controls that enables greater comfort and economy, helping to save you money on your energy bills.

Does this range come with any options?

As well as the 30 kW unit, Greenstar boilers are also available with a 25 kW output rating. While the 30 kW is suited to larger homes with a high demand for heating and hot water, the 25 kW is a better option for medium-sized homes that don’t have such an excessive need for heating and hot water.

Where can this boiler be installed?

This is a compact wall-mounted boiler that will help to save you some much needed space in the home.

How long is the warranty period?

As standard, the Greenstar 30i comes with a 5 year warranty that can be increased to 7 years when installed by a Worcester accredited installer.

To make the warranty valid, you’ll need to register it within 30 days and have the boiler serviced annually to avoid the warranty ending early.
