Worcester Bosch Greenstar 8000 Style 50kW Combi Gas boiler frequently asked questions

Which category of boiler does the Worcester Bosch Greenstar 8000 Style 50kW fit into?

The Worcester Bosch Greenstar 8000 Style 50kW boiler could be suitable for your house or flat if you are looking for a new combi boiler.

Combi boilers have much to recommend them - not least the fact that they save a lot of space. Combination (or combi) boilers were introduced by manufacturers in the 1970s to provide practical central heating and hot water distribution to smaller properties - remember that UK houses and flats tend to be among the smallest in the developed world.

Traditional boilers require one or more storage tanks to keep hot water warm and to store water for heating later. In contrast, combi boilers draw water directly from the mains supply and heat it instantly, removing the need for a storage tank. The heated water is then distributed to your taps and radiators on demand.

While combi boilers are suitable choices for many properties, especially those without a loft, there is also a disadvantage in using them. Water is heated instantly and the volume of water that can be heated at any one time is limited. This can result in less water being sent to taps and showers if more than one is being used simultaneously. In these instances, the water pressure to both points will drop.

Is the Worcester Bosch Greenstar 8000 Style 50kW combi boiler a suitable choice for my property?

Whether this Worcester Bosch Greenstar 8000 Style 50kW Combi boiler is right for where you live 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 of a boiler is measured in kilowatts and indicates how much energy it can use to heat the water needed for your radiators, taps and showers. The greater the output, the more water it can heat.

A boiler whose output is too high will give you hot water and warm radiators but also higher gas bills, whereas a boiler whose output is too low will result in cheaper gas bills but the water might not always be as hot as you want it to be.

The output of the Worcester Bosch Greenstar 8000 Style 50kW combi is 50 kW, so which types of property would this model be appropriate for?

A PlumbProud Gas Safe boiler installer would recommend that this Worcester Bosch Greenstar 8000 Style 50kW Combi boiler is appropriate for larger properties including detached homes with 15 or more radiators and two or more bathrooms.

Homeowners considering fitting a combi boiler to their home need to consider flow rates as well as output rates.

The flow rate is a measurement of the volume of water a combi can instantly heat and send to the taps and radiators around your home. The higher the likely demand for hot water in your home, the higher your combi's flow rate should be. This Worcester Bosch Greenstar 8000 Style 50kW Combi boiler's flow rate is 18 L/m.

Unlike heat only or system boilers, combi boilers don't store hot water in a tank for later use - instead, they draw it directly from the mains. This means that the volume of water your boiler can actually process is constrained by the flow rate of water in the mains pipe.

So, if you choose a combi boiler with a 15l/m flow rate but the flow rate in your mains pipe is 12l/m, the combi boiler's working flow rate is also 12l/m.

Combi boilers are also not always the correct choice for homes with multiple bathrooms, a high number of radiators, or where more than one family member will want to use hot water at the same time.

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 dimensions of the Worcester Bosch Greenstar 8000 Style 50kW are

The size of the Worcester Bosch Greenstar 8000 Style 50kW boiler is 825 mm tall, 440 mm wide, and 365 mm deep.

Worcester Bosch Greenstar 8000 Style 50kW – condensing or non-condensing?

Condensing boilers convert the warmth present in flue exhaust gases and water vapour condensation into heat which they then recycle to increase the temperature of the colder water returning to your system.

We recommend that homeowners choose a condensing boiler like the Worcester Bosch Greenstar 8000 Style 50kW for this reason - the more recent your model the better because the technology improves every year.

You'll benefit from lower quarterly gas bills and condensing boilers are also much more environmentally friendly.

Is the Worcester Bosch Greenstar 8000 Style 50kW combi boiler good for the environment?

Environmentally-friendly heating has become an important issue for homeowners concerned about the accelerating pace of climate change.

Central heating creates 14% of the UK’s greenhouse gases. And in Britain's larger cities, gas boilers are responsible for dangerous levels of nitrogen dioxide emissions.

If you would like your next boiler to help in the fight against climate change, would the Worcester Bosch Greenstar 8000 Style 50kW combi be a suitable choice?

All boilers manufactured and installed in the UK are required by law to have an energy efficiency rating of at least 92%, equivalent to a good “A” rating on the SEDBUK scale. Before this, the minimum was 88% (ratings of 88% and 89% are equivalent to a high “B” SEDBUK rating and anything 90% or higher is an "A" rating).

A boiler's energy efficiency rating is designed to let you know how much energy is used and wasted during normal functioning.

The Worcester Bosch Greenstar 8000 Style 50kW was given an efficiency rating of 94% and a band rating of "A".

The ERP (or Energy Related Products Directive) is European legislation which applies to all products that consume energy throughout their lifetime.

Its purpose is to encourage manufacturers to offer products that are kinder to the environment by reducing harmful gas emissions at all stages, from production and end use right through to disposal.

The ERP rating for the Worcester Bosch Greenstar 8000 Style 50kW is "A" for heat and "A" for water.

If the Worcester Bosch Greenstar 8000 Style 50kW breaks down, will I be covered by the warranty?

The Worcester Bosch Greenstar 8000 Style 50kW boiler is covered by a parts and labour warranty of 8 years.

Worcester Bosch Greenstar 8000 Style 50kW Combi Gas boiler frequently asked questions

What type of boiler is the Worcester Bosch Greenstar 8000 Style 50kW?

You might want to consider the Worcester Bosch Greenstar 8000 Style 50kW for your house or flat if you are looking for a combi boiler.

Traditional boilers often have up to two tanks that either store heated water or water to be heated later. Boiler manufacturers introduced combi boilers in the 1970s to avoid the need for those big tanks. Combi boilers allow homeowners to benefit from the reliable central heating and hot water level they want but without having to give up so much space within their properties - remember that homes in the UK are among the smallest in the developed world.

Your taps and radiators get the hot water they need with a combi boiler. Combi boilers draw cold water direct from the mains which is then heated instantly on demand and distributed to your radiators and taps.

However, combi boilers cannot heat very large volumes of water, which is their main disadvantage. So, for example, when someone wants to take a shower while another person wants to use a hot water tap to do the dishes, water pressure and quantity to both points decreases.

Is the Worcester Bosch Greenstar 8000 Style 50kW combi boiler a suitable choice for my property?

You should make sure that the boiler you install in your property is the right "size". And size doesn't mean its physical dimensions, size means how much power it has - the "output".

Output measures in kilowatts how much power a boiler can use when heating water for your radiators or taps. The higher the output rate, the more water it can heat.

If the output rate is too low, your hot water might often be only lukewarm, and if it is too high, you will be paying more for your gas than you need to.

The Worcester Bosch Greenstar 8000 Style 50kW combi boiler has an output of 50 kW, so which types of property would it be most appropriate for?

A Gas Safe engineer would recommend that the Worcester Bosch Greenstar 8000 Style 50kW combi boiler would be an ideal installation option for larger properties including detached homes with 15 or more radiators and two or more bathrooms.

You also need to choose a combi boiler with the right flow rate for where you live.

A combi boiler's flow rate is the maximum volume of water (measured in litres per minute) that it can heat and distribute to your radiators, taps and showers at the same time. This Worcester Bosch Greenstar 8000 Style 50kW Combi boiler's flow rate is 18 L/m.

However, combi boilers like the Worcester Bosch Greenstar 8000 Style 50kW draw water directly from the mains and heat it instantly.

If your mains pressure is 12 litres per minute, your boiler can only heat and distribute hot water at a rate of 12 litres per minute even if it has a higher flow rate.

Combi boilers also struggle when multiple people in your home want to use hot water at the same time - for example, someone running the hot water tap in the kitchen and two people wanting to shower in separate bathrooms.

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.


How large is a Worcester Bosch Greenstar 8000 Style 50kW boiler?

The Worcester Bosch Greenstar 8000 Style 50kW boiler measures 825 mm [H] x 440 mm [W] x 365 mm [D] in size.

Worcester Bosch Greenstar 8000 Style 50kW – non-condensing or condensing?

We recommend that you choose a condensing boiler wherever possible like the Worcester Bosch Greenstar 8000 Style 50kW - try to go for the latest model, if possible, to take advantage of improving technology.

Condensing boilers capture and recycle the warmth still present in the water vapour condensation and in flue exhaust emissions created by burning gas to make them more efficient and economical to run.

You will save money on your gas bills too, plus condensing boilers are friendlier to the environment.

What energy efficiency ratings have been awarded to the Worcester Bosch Greenstar 8000 Style 50kW combi?

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

In the UK, central heating is responsible for 14% of greenhouse gas production. Domestic gas boilers emit large quantities of nitrogen dioxide in British cities.

Will you be helping the environment if you decide to install a Worcester Bosch Greenstar 8000 Style 50kW combi in your home? Let’s look at the figures.

All boilers manufactured and installed in the UK are required by law to have an energy efficiency rating of at least 92%, equivalent to a good “A” rating on the SEDBUK scale. Before this, the minimum was 88% (ratings of 88% and 89% are equivalent to a high “B” SEDBUK rating and anything 90% or higher is an "A" rating).

A boiler's energy efficiency rating is designed to let you know how much energy is used and wasted during normal functioning.

The Worcester Bosch Greenstar 8000 Style 50kW was given an efficiency rating of 94% and a band rating of "A".
