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

Is the Worcester Bosch Greenstar 8000 Style 50kW a combi boiler, system boiler or regular boiler?

If you are searching for a combi boiler for your house or flat, the Worcester Bosch Greenstar 8000 Style 50kW is certainly one to consider.

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.

Should I install a Worcester Bosch Greenstar 8000 Style 50kW combi boiler in my house or apartment?

Whether this Worcester Bosch Greenstar 8000 Style 50kW 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 50kW combi is 50 kW, so which types of property is this Worcester Bosch Greenstar 8000 Style 50kW Combi boiler appropriate for?

An experienced PlumbProud Gas Safe boiler installer would almost certainly recommend that this Worcester Bosch Greenstar 8000 Style 50kW Combi boiler would be most suitable for larger properties including detached homes with 15 or more radiators and two or more bathrooms.

Flow rates are important when choosing a combi boiler as well as output rates.

A combi boiler's flow rate (measured in litres per minute) describes how much water it can instantly heat then distribute to the taps and radiators in your home - you will need to factor this into your decision on a new combi boiler. This Worcester Bosch Greenstar 8000 Style 50kW Combi boiler's flow rate is 18 L/m.

If you have a lot of radiators and bathrooms in your home and there's lots of demand within your household for hot water at the same time (like morning or evening showers and baths), you'll need a boiler with a high flow rate.

However, it's not quite that simple. If your local mains water pressure is low, you're not going to gain any benefit from choosing a combi boiler with a high flow rate because that higher flow rate doesn't mean it can draw more water from the mains pipes.
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 50kW

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

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

Condensing boilers like the Worcester Bosch Greenstar 8000 Style 50kW improve energy efficiency and reduce your annual expenditure on gas.

They do this by capturing and recycling the warmth still present in water vapour condensation and flue exhaust gases to, for example, increase the temperature of the colder water returning from your radiators.

Condensing boilers are also much better for the environment because they emit fewer greenhouse gases.

Is the Worcester Bosch Greenstar 8000 Style 50kW combi environmentally friendly?

More and more homeowners are aware of the importance of how we heat our homes and its impact on climate change and other environmental issues.

With central heating being responsible for 14% of greenhouse gas emissions in the UK, your choice of boiler matters. Gas boilers are also responsible for the significant atmospheric volumes of dangerous nitrogen dioxide emissions in larger British cities.

Will installing a Worcester Bosch Greenstar 8000 Style 50kW combi be a positive contribution to the environment? Let's see what the experts say.

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 50kW was awarded an efficiency rating of "94%", equivalent to a "A" rating on the SEDBUK system.

The Energy Related Products (ERP) Directive is important European legislation that aims to limit energy use and harmful gas emissions during the manufacturing process, when the product is in use, and after it is disposed of.

For the Worcester Bosch Greenstar 8000 Style 50kW, the ERP Heat rating is "A" and the ERP Water rating is "A".

If the Worcester Bosch Greenstar 8000 Style 50kW combi boiler breaks down, am I covered?

Parts and labour charges incurred for repairs made to your new Worcester Bosch Greenstar 8000 Style 50kW are covered by a 8 year warranty.

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

Is the Worcester Bosch Greenstar 8000 Style 50kW a standard, combi or system boiler?

Worcester Bosch’s Greenstar 8000 Style 50kW is one you might consider if you’re looking for a combi boiler for your house or flat.

Traditional boilers need one or more large tanks to work - one to heat and keep water warm for immediate use and the other to store water intended for heating later. Finding space for these large tanks is difficult in British residential property - remember that our houses and flats are among the smallest in the world. This is the problem that combi boilers were designed to solve when they were introduced in the 1970s.

Combi boilers don't need a tank - instead, they instantly heat water drawn from the mains using technology inside the boiler. This hot water is then distributed immediately to your taps or radiators on demand.

The biggest disadvantage to combi boilers is that they have a maximum capacity for heating water, meaning that they work best when only one point within a household wants hot water. For example, if someone is taking a shower and another person uses a hot water tap at the same time, the water pressure, volume and temperature to both points drops.

Is the Worcester Bosch Greenstar 8000 Style 50kW combi boiler suitable for my house or apartment?

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?

Most heating engineers would recommend that this Worcester Bosch Greenstar 8000 Style 50kW Combi boiler would be suitable for larger properties including detached homes with 15 or more radiators and two or more bathrooms.

Please remember too that all combi boilers draw water from the mains - they have no storage tanks. Combis heat the water from the mains on demand and then send it to wherever it's needed in the house, like a radiator, a bathroom or a kitchen.

The speed at which it can do this is called the "flow rate", which is measured in litres per minute. If you have a lot of radiators and bathrooms in your home and multiple people are regularly trying to use the hot water at one time, such as in the morning or evening, you'll need a combi with a high flow rate. This Worcester Bosch Greenstar 8000 Style 50kW Combi boiler's flow rate is 18 L/m.

However, it's not that simple. Combis can only draw water from the mains at the speed it's delivered. If the flow rate of the local water supply is 11l/m, you shouldn't purchase a boiler with a flow rate of 17l/m because it will never be able to use that extra capacity.

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 size is a Worcester Bosch Greenstar 8000 Style 50kW boiler?

Worcester Bosch’s Greenstar 8000 Style 50kW is 825 mm tall, 440 mm wide, and 365 mm deep.

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

We recommend that you select a condensing boiler like the Worcester Bosch Greenstar 8000 Style gas Worcester Bosch Greenstar 8000 Style 50kW for your home if possible because of the environmental benefits and the money you'll save on your gas bills.

Condensing boilers are much more energy-efficient than older, non-condensing models as they capture and recycle the heat still present in the water vapour condensation and flue exhaust gases that your boiler creates when burning gas for reuse.

How environmentally friendly is the Worcester Bosch Greenstar 8000 Style 50kW combi?

How we heat our homes is an issue which many homeowners worry about as the world combats climate change and environmental damage.

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.

Is the Worcester Bosch Greenstar 8000 Style 50kW combi boiler an environmentally friendly choice for your home? Here’s what the figures say.

The Worcester Bosch Greenstar 8000 Style 50kW has been awarded an efficiency rating of 94% and a SEDBUK band rating of "A".

In the UK, all boilers manufactured and supplied must have an energy efficiency rating of at least 92% or a SEDBUK "A" grade. Until April 2018, the minimum rating was 88% (88% and 89% are equivalent to a SEDBUK "B" rating and anything higher is rated "A").

A boiler's energy efficiency rating describes the amount of energy it uses and wastes when in normal operation.

The Energy Related Products Directive (ERP) was introduced in 2015 and it 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 8000 Style 50kW has an ERP rating of "A" for heat and "A" for hot water production.

How long is the warranty offered by the manufacturer for the Worcester Bosch Greenstar 8000 Style 50kW boiler?
