Worcester Bosch Greenstar i System 9i System Gas boiler frequently asked questions

Worcester Bosch Greenstar I System 9i - a regular boiler, combi boiler or system boiler?

If you want a system boiler for your flat or house, the Worcester Bosch Greenstar I System 9i might be an option for you to consider.

As with a heat only boiler, a system boiler requires the installation of a hot water cylinder but they do not need a cold water tank to work. This makes them suitable choices for homeowners planning a loft conversion or for properties without a loft or very limited attic space.

The primary heating and hot water system components are built in to system boilers and you can use the control panel to set the times that you wish your heating and hot water to be available. Hot water is stored in the cylinder for use throughout the day, but if you don't set your timer, heat and hot water will not be available instantly.

A system boiler can supply multiple taps and showers simultaneously and is suitable for both large families and properties with more than one bathroom - combi boilers struggle to do this.

Is the Worcester Bosch Greenstar I System 9i system boiler suitable for my house or apartment?

Selecting the right boiler for your property means selecting a boiler that is the right "size". And, by size, we don't mean how big it is, we mean how powerful it is - its "output".

The output rate tells you how much energy your boiler has to use to provide you and your family with hot water and central heating. A higher output rate means that it can heat greater volumes of water.

Please be aware, though - if you choose a boiler whose output is too low, the water in your radiators and coming from your taps may not be warm enough. Conversely, if you choose a boiler with too high an output, you'll pay more for gas than is necessary.

The Worcester Bosch Greenstar I System 9i system boiler has an output level of 9 kW, so which types of property would it be appropriate for?

A PlumbProud Gas Safe engineer would recommend that the most suitable type of property for a Worcester Bosch Greenstar I System 9i system would be smaller homes and apartments containing up to 10 radiators and providing hot water for one bathroom.


The size of the Worcester Bosch Greenstar I System 9i in millimetres

The size of the Worcester Bosch Greenstar I System 9i boiler is 710 mm high, 400 mm wide, and 330 mm deep.

Is the Worcester Bosch Greenstar I System 9i condensing or non-condensing?

The Worcester Bosch Greenstar I System 9i boiler is a condensing gas boiler and we recommend that you select one of the latest models if possible.

Condensing boilers reduce homeowners' gas bills and are better for the environment. They do this by capturing and recycling the heat still present in the flue exhaust gases and water vapour condensation produced when boilers burn gas to generate the power they need to operate.

Is the Worcester Bosch Greenstar I System 9i system environmentally friendly?

Concern for the environment is causing more and more homeowners to think about how they heat their homes and its impact on climate change.

Dangerous levels of nitrogen dioxide emissions in larger UK cities are caused by gas boilers in domestic properties, and 14% of the UK’s greenhouse gas production is as a result of central heating.

If you would like your next boiler to help in the fight against climate change, would the Worcester Bosch Greenstar I System 9i system be a suitable choice?

All boilers manufactured and supplied in the UK are assigned two energy efficiency ratings. By law, they must achieve a SEDBUK "A" rating subject to a minimum efficiency level of 92%. Prior to that, the minimum was 88% (88% and 89% are equivalent to a SEDBUK "B" grade and 90% and above an "A" grade).

The ratings awarded to the Worcester Bosch Greenstar I System 9i are 93% with a SEDBUK rating of "A".

The Energy Related Products Directive (ERP) came into force in 2015. This legislation was introduced to encourage manufacturers to create more energy-efficient products and it covers all products that consume energy during their lifetimes, including energy used during production and at the point of disposal.

The ERP assessors assigned a rating of "A" when testing the Worcester Bosch Greenstar I System 9i.

How many years does the warranty period cover on a Worcester Bosch Greenstar I System 9i boiler?

Parts and labour charges incurred during a repair on the Worcester Bosch Worcester Bosch Greenstar I System 9i boiler are covered by a 7 year warranty.

Worcester Bosch Greenstar i System 9i System Gas boiler frequently asked questions

Worcester Bosch Greenstar I System 9i - a combi boiler, system boiler or regular boiler?

You may wish to consider installing the Worcester Bosch Greenstar I System 9i if you are looking for a system boiler for your house or flat.

If you choose a system boiler, you'll have to find somewhere to install a hot water cylinder too - they're normally located in an airing or landing cupboard. However, unlike regular boilers, they do not require a cold water tank to be fitted in the attic, making them suitable for homes with limited or no roof space or if you're planning a loft conversion in the future.

System boilers distribute the hot water to your taps and radiators using (often built-in) circulation pumps and are easier to install from scratch since they have one less component (the water tank) to consider.

System boilers also require programming to produce heat and hot water, so they cannot produce this instantly. Nonetheless, the cylinder keeps water hot for use later, so you don't have to wait as long as you set your timer and keep it on long enough to heat enough water.

Is the Worcester Bosch Greenstar I System 9i system boiler suitable for my house or apartment?

Whether this Worcester Bosch Greenstar i System 9i System boiler is right for your property depends on its size or what its "output" level is. Size does not mean its physical dimensions, however - it means how powerful it is.

The output rating indicates how much energy a boiler can use in providing you with hot water and heat when you need it from your radiators and taps. The greater the output, the more water it can heat.

It's better to take advice on this from a registered installer because, if your boiler output is too low, your water and radiators might not get as hot as you would like them to be. However, if the output level is too high, you'll end up paying more on your gas bills than you need to.

Which types of property would this Worcester Bosch Greenstar i System 9i System boiler be appropriate for given its output of 9 kW?

A PlumbProud Gas Safe engineer would recommend that the most suitable type of property for a Worcester Bosch Greenstar I System 9i system would be smaller homes and apartments containing up to 10 radiators and providing hot water for one bathroom.


Worcester Bosch Greenstar I System 9i dimensions

The Worcester Bosch Greenstar I System 9i boiler measures 710 mm [H] x 400 mm [W] x 330 mm [D] in size.

Is the Worcester Bosch Greenstar I System 9i a condensing or non-condensing boiler?

We always recommend to clients that they select the very latest condensing boiler for their home.

Condensing boilers like the Worcester Bosch Greenstar I System 9i are more efficient with the gas they use in operation, meaning that you'll benefit from lower fuel bills. Condensing boilers are also better for the environment.

They achieve their efficiency by capturing and recycling the heat still present in the water vapour condensation and flue exhaust gases created when a boiler burns gas to get the energy it needs. It then reuses that recycled heat to perform a number of tasks, including heating the colder water that comes back to your boiler via the radiator.

Is the Worcester Bosch Greenstar I System 9i system a good choice for the environment?

As the British public has become more conscious of climate change, many homeowners consider the environment when choosing how to heat their homes.

Central heating produces 14% of all greenhouse gas emissions in the UK. Gas boilers in the larger cities emit dangerous levels of nitrogen dioxide.

Do the available figures suggest that installing the Worcester Bosch Greenstar I System 9i system in your property would be an environmentally friendly choice?

Boilers manufactured and installed in the UK are assigned energy efficiency ratings following testing to an agreed set of standards. These scores indicate how much energy the boiler uses and how much goes to waste when it's in operation.

By law, boilers must achieve a SEDBUK rating of "A" subject to achieving a minimum of 92% energy efficiency. Prior to April 2018, the minimum was 88% (88% and 89% on the SEDBUK are graded "B" and 90% and above is graded "A").

The Worcester Bosch Greenstar I System 9i was awarded an efficiency rating of 93% with a SEDBUK band rating of "A".

The Energy Related Products Directive (ERP) was introduced in 2015 and applies to all products that consume energy throughout their lifetime, including during the manufacturing process and at the point of final disposal.

The purpose of the ERP is to ensure that companies create products that are kinder to the environment by reducing both the energy they use and the harmful emissions they produce.

The Worcester Bosch Greenstar I System 9i has an ERP rating of "A".

What is the length of the warranty on the Worcester Bosch Greenstar I System 9i?

The Worcester Bosch Greenstar I System 9i boiler comes with a 7 year warranty for parts and labour.
