Worcester Bosch Greenstar 8000 Style 30kW Combi Gas boiler frequently asked questions

Is the Worcester Bosch Greenstar 8000 Style 30kW boiler a combi, regular or a system boiler?

The Worcester Bosch Greenstar 8000 Style 30kW is a gas combi boiler.

Combination or combi boilers are highly efficient and save a lot of space in your home. Combi boilers heat water directly from the mains when you turn on a tap and, as a result, you don’t need a hot water storage cylinder or a cold water tank in the roof space.

These boilers are, therefore, suitable for smaller homes and especially those without a loft. They are also cost-effective as the water is heated instantly and distributed on demand rather than being stored. Combi boilers are the most popular type of boilers in the UK and replacing an older boiler with a new combi boiler will reduce your gas bills significantly.

However, there are downsides to this type of boiler. If you take a shower while someone else is using a tap, less water will reach each point of usage at lower rates of pressure and temperatures as combi boilers can only heat a certain volume of water at any given time.

Is the Worcester Bosch Greenstar 8000 Style 30kW combi boiler a suitable choice for my property?

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 8000 Style 30kW combi boiler has an output level of 30 kW, so which types of property would it be appropriate for?

Most heating engineers would recommend this Worcester Bosch Greenstar 8000 Style 30kW Combi boiler as a suitable option for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

With all combi boilers, the "flow rate" (measured in litres per minute) is as important a consideration as output rate when choosing which model to go for. This Worcester Bosch Greenstar 8000 Style 30kW Combi boiler's flow rate is 11 L/m.

Like all combi boilers, the Worcester Bosch Greenstar 8000 Style 30kW draws water from the mains. It instantly heats that water and then distributes it to the parts of your home which need it - taps, radiators, bathrooms, and so on.

However, the water in the mains pipe that feeds your boilers has its own flow rate - normally between 10 and 12l/m. So if you choose a combi with a flow rate of 14l/m but local water pressure is equivalent to 11l/m, your boiler will actually operate at 11l/m - below its capacity.

In addition, if different family members want hot water at the same time (like for regular morning and evening showers) and your boiler has to provide hot water to your radiators at the same time, a combi boiler may not be suitable.

When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead if your family's demand for hot water is higher than normal.


The size of the Worcester Bosch Greenstar 8000 Style 30kW in millimetres

The Worcester Bosch Greenstar 8000 Style 30kW measures 825 mm high and 440 mm wide by a depth of 365 mm.

Worcester Bosch Greenstar 8000 Style 30kW – condensing or non-condensing?

The Worcester Bosch Greenstar 8000 Style 30kW is a condensing gas boiler - where possible, we always recommend to clients that they choose one of the very latest condensing boilers to take advantage of this technology, which improves year after year.

Condensing boilers are more energy-efficient as they capture and recycle the heat contained in flue exhaust gases and water vapour condensation. They then use this heat to perform tasks like warming up colder water returning to the boiler from the radiators.

By choosing a condensing boiler, you'll help the environment as well as save money on your gas bills.

How does the Worcester Bosch Greenstar 8000 Style 30kW combi rate environmentally?

Many homeowners are becoming increasingly concerned about how they heat their homes and the impact it has on climate change and other important environmental issues.

We generate 14% of UK greenhouse gas emissions through centrally heating our domestic properties. Gas boilers are mainly responsible for harmful nitrogen dioxide emissions in larger British cities.

Do the available figures suggest that installing the Worcester Bosch Greenstar 8000 Style 30kW combi 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 8000 Style 30kW was awarded an efficiency rating of 94% with a SEDBUK band rating of "A".

The Energy Related Products Directive, also known as ERP, is European legislation that intends to reduce energy consumption related to products right from the initial manufacturing process through to eventual final disposal.

The purpose of the directive is to encourage manufacturers to create new products that are kinder to the environment and which result in lower overall harmful gas emissions through a product's entire life cycle.

The Worcester Bosch Greenstar 8000 Style 30kW has a rating of "A" for heat and "A" for water.

What length of warranty does the Worcester Bosch Greenstar 8000 Style 30kW come with?

The Worcester Bosch Greenstar 8000 Style 30kW is supplied with a parts and labour warranty of 8 years.

Worcester Bosch Greenstar 8000 Style 30kW Combi Gas boiler frequently asked questions

What type of boiler is the Worcester Bosch Greenstar 8000 Style 30kW - regular, system or combi?

The Worcester Bosch Greenstar 8000 Style 30kW is an option you may wish to consider if you’re looking for a combi boiler for your house or flat.

Traditional boilers consist of one or more large tanks that take up a lot of space in people's homes. One tank heats water and keeps it warm and the other stores water for heating later.

In contrast, a combi boiler is a much smaller stand-alone unit. Instead of requiring water tanks, it draws cold water from the mains. When hot water is needed for a shower, for the washing up, or the dishwasher, the cold water is heated instantly by the boiler and distributed to where it is needed.

The main disadvantage of combi boilers is that there is a limit to how much water they are capable of heating at the same time. For instance, water pressure, volume and temperature will be adversely affected if more than one individual in the home needs hot water at the same time.

Is the Worcester Bosch Greenstar 8000 Style 30kW combi suitable for my house or flat?

Whether this Worcester Bosch Greenstar 8000 Style 30kW Combi boiler is right for where you live depends on its size or "output" level. Size does not mean its physical dimensions, however - it means how powerful it is.

Measured in kilowatts, a boiler's output level is an indication of the amount of power it has available to it to heat the water coming from your taps and for warming your radiators. The greater the output level, the more water it can heat.

If you choose a boiler whose output level is too low, you'll often find that the water is not as hot as you want it to be. If you choose a boiler whose level is too high, you'll be paying higher gas bills than you need to for years to come.

The output of the Worcester Bosch Greenstar 8000 Style 30kW combi is 30 kW, so which types of property is this Worcester Bosch Greenstar 8000 Style 30kW Combi boiler appropriate for?

An experienced boiler engineer would recommend that this Worcester Bosch Greenstar 8000 Style 30kW Combi boiler would provide adequate heating and hot water for medium-sized homes and larger apartments with up to 10-15 radiators and two bathrooms.

If you are considering installing a combi boiler in your home, you need to consider the flow rate as well as the output rate.

The flow rate is the volume of water (measured in litres per minute) that your boiler can instantly heat up and send around the home. The more demand in your home for water at the same time (for example, two people taking showers in different bathrooms), the higher the flow rate you'll need.

However, the actual flow rate your boiler can deliver is also determined by your mains water pressure. If you choose a boiler with a flow rate of 16l/m but the mains water pressure is 12l/m, your boiler will only perform to 12l/m. This Worcester Bosch Greenstar 8000 Style 30kW Combi boiler's flow rate is 11 L/m.

When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead if your family's demand for hot water is higher than normal.


What dimensions does a Worcester Bosch Greenstar 8000 Style 30kW have?

The Worcester Bosch Greenstar 8000 Style 30kW boiler is 825 mm high, 440 mm wide, and 365 mm deep.

Is the Worcester Bosch Greenstar 8000 Style 30kW condensing or non-condensing?

The Worcester Bosch Greenstar 8000 Style 30kW is a condensing gas boiler - we strongly recommend that you choose one of the latest condensing models if possible.

With a condensing boiler, you save money on your gas bills because your boiler captures and recycles the heat present in the flue exhaust gases and water vapour condensation for re-use, meaning they operate far more economically and efficiently.

Is the Worcester Bosch Greenstar 8000 Style 30kW combi an energy-efficient boiler?

How we heat our homes has become a pressing issue of concern for many homeowners worried about climate change and the environmental impact of their personal choices.

The power we need for our central heating systems accounts for around 14% of the UK’s greenhouse gas production. There are often dangerous levels of ambient nitrogen dioxide gases in the atmospheres of British cities because of our use of gas boilers.

Do the figures suggest that installing the Worcester Bosch Greenstar 8000 Style 30kW combi at your property would help in the fight against climate change?

An energy efficiency rating of 92% or above is a legal requirement for all boilers manufactured and installed in the UK today. 92% is equivalent to a low-to-middle "A" grade on the "Seasonal Efficiency of Domestic Boilers" (SEDBUK) scale.

Energy efficiency measures how much energy a boiler uses and wastes in the course of its normal operation. The lower the waste, the lower your gas bills.

The Worcester Bosch Greenstar 8000 Style 30kW was awarded an efficiency rating of "94%", equivalent to a "A" rating on the SEDBUK system.

The Energy Related Products Directive, also known as ERP, is European legislation that intends to reduce energy consumption related to products right from the initial manufacturing process through to eventual final disposal.

The purpose of the directive is to encourage manufacturers to create new products that are kinder to the environment and which result in lower overall harmful gas emissions through a product's entire life cycle.

The Worcester Bosch Greenstar 8000 Style 30kW has a rating of "A" for heat and "A" for water.

How long is the warranty period on the Worcester Bosch Greenstar 8000 Style 30kW combi boiler?

You receive a parts and labour warranty of 8 years with the Worcester Bosch Greenstar 8000 Style 30kW boiler.
