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

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

The Worcester Bosch Greenstar 8000 Life 50kW is a combi boiler you may wish to consider if you want this particular type of boiler for your house or flat.

Combi boilers are excellent for providing hot water and heat for your radiators just when you need it. When you have a combi boiler installed in your home, you just turn on the tap and the hot water for your bath, shower, washing dishes and other activities is there when you need it. It also provides the heat you need to keep your radiators warm.

A combi boiler heats the cold water passing through it, which it draws from the mains. This newly heated water can then be distributed to whichever hot tap or radiator needs it.

In the past, boilers needed at least one storage tank to hold water that was either already heated or would be heated later. Sometimes, you'd have to wait for hot water because there was none left. In addition, storage tanks took up a lot of space and most UK homes are pretty small.

The main disadvantage to combi boilers is that they can only heat a certain amount of water at any one time, meaning the pressure, volume and temperature of water will decrease if more than one tap is on at the same time or if both the shower and washing machine are on together.

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

Whether this Worcester Bosch Greenstar 8000 Life 50kW Combi boiler is right for where you live depends on its size or "output" level. Size does not mean its physical dimensions - it means how powerful it is.

A boiler’s output is a measurement of the amount of power it can use to provide hot water to your taps and radiators. The higher its output rate, the more water it can heat.

If your new boiler’s output is too low, your hot water might not be as hot as you want it to be. If it's too high, you’ll be paying more for gas than you need to.

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

A PlumbProud Gas Safe boiler installer would recommend that the most suitable type of property for this Worcester Bosch Greenstar 8000 Life 50kW Combi boiler would be larger properties including detached homes containing 15 or more radiators and two or more bathrooms.

In addition to the output rate, you should consider a boiler's "flow rate" (measured in litres per minute) when choosing a combi boiler.

If you have a lot of radiators and bathrooms in your home and members of your household want to use hot water at the same time (like morning or evening showers and baths), you'll need a boiler with a high flow rate. This Worcester Bosch Greenstar 8000 Life 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. Homes with higher than average demand for hot water, and particularly those in low mains pressure areas, may find that a combi boiler is not the right answer for them.

When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead to better serve you and your family.


Where will the Worcester Bosch Greenstar 8000 Life 50kW fit in my house?

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

Is this Worcester Bosch boiler non-condensing or condensing?

The Worcester Bosch Greenstar 8000 Life 50kW is a condensing gas boiler - we’d strongly recommend that you choose the very latest condensing model for your home.

Condensing boilers run on either gas or oil and are manufactured specifically to improve energy efficiency. They do this by capturing and recycling the warmth present in flue exhaust gases and water vapour condensation into more usable heat the system can use, meaning they're far more efficient and cost less to run.

Is the Worcester Bosch Greenstar 8000 Life 50kW combi rated as environmentally friendly?

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

In the largest cities of Britain, gas boilers are responsible for dangerous levels of atmospheric nitrogen dioxide emissions. In total, 14% of the UK’s greenhouse gases are produced by central heating systems.

Would installing the Worcester Bosch Greenstar 8000 Life 50kW combi in your home be an environmentally friendly decision? Let's look closely at the figures.

The energy efficiency rating of the Worcester Bosch Greenstar 8000 Life 50kW is 94% with a SEDBUK band rating of "A".

Energy efficiency tests record how much energy is wasted on non-core functions during an operation.

By law, all boilers manufactured and supplied in the UK must have a minimum energy efficiency performance level of 92% (equivalent to a SEDBUK "A" grade). Up to April 2018, the minimum performance level was 88% (88% and 89% are equivalent to a SEDBUK "B" grade and 90%+ an "A" grade).

The ERP, short for the Energy Related Products Directive, is a European directive aimed at encouraging manufacturers to create products that are environmentally friendlier at all stages, including during manufacturing, when the product is in active use, right through to the point of final disposal.

The Worcester Bosch Greenstar 8000 Life 50kW has a rating of "A" for heat and "A" for hot water production.

What length of warranty does the Worcester Bosch Greenstar 8000 Life 50kW come with?

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

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

If you are considering installing a combi boiler in your house or flat, then the Worcester Bosch Greenstar 8000 Life 50kW boiler is certainly worth investigating.

In older British homes, traditional boilers required you to find room for one or more storage tanks. One tank would keep hot water warm and the other stored cold water for later heating. Manufacturers introduced combi boilers to the UK in the 1970s so that homeowners could get the warmth and hot water they needed without having to sacrifice too much valuable space – remember that residential property in this country is among the smallest in the Western world.

Combi boilers deliver hot water to your radiators and taps using water they draw directly from the mains supply. As mains water travels through a combi boiler, the technology within it heats the cold water instantly and on demand. The hot water is then distributed throughout your house.

Combi boilers have one drawback, however: they can only heat a certain amount of water within a given time. For example, if someone uses the shower and another person uses the hot water tap at the same time, water pressure drops because water reaches each point differently.

Should I install a Worcester Bosch Greenstar 8000 Life 50kW combi boiler in my home?

To determine that, we need to consider the size of the boiler. However, size doesn't refer to how big a boiler is - it means the size of its "output".

Your boiler’s output is a measurement of the power it has available to heat the volume of water required for your taps and radiators. The higher the output rate, the more water it can heat.

You need to be careful to select a boiler with the optimal level of output for your property though. That's because, if your boiler output is too low, your water and radiators will often not be as hot as you want them to be. If the output is too high, you’ll be paying more for gas than you need to.

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

A Gas Safe boiler installer would recommend that, at this level of output, the most suitable type of property for this Worcester Bosch Greenstar 8000 Life 50kW Combi boiler would be 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 Life 50kW Combi boiler's flow rate is 18 L/m.

However, combi boilers like the Worcester Bosch Greenstar 8000 Life 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.


What are the dimensions of the Worcester Bosch Greenstar 8000 Life 50kW boiler?

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

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

The Worcester Bosch Greenstar 8000 Life 50kW is a condensing gas boiler - in fact, we recommend that you select this model or one of the latest condensing boilers on the market as the technology continues to improve over time.

Condensing boilers capture the heat still present in the flue exhaust gases and water vapour condensation created when the gas is burned and they recycle this back into the heating system to warm up the cold water re-entering the boiler from your radiators.

They're much more environmentally friendly and installing one results in much lower annual gas bills.

Is the Worcester Bosch Greenstar 8000 Life 50kW combi boiler an environmentally friendly choice?

With more and more people concerned about climate change, how we heat our homes and the damage it does to the environment is increasingly being questioned by British homeowners.

Central heating accounts for 14% of greenhouse gas emissions in the UK. In larger British cities, gas boilers emit dangerous levels of nitrogen dioxide into the atmosphere.

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

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 Life 50kW was awarded an efficiency rating of 94% with a SEDBUK band rating of "A".

The Energy Related Products (ERP) directive is Europe-wide legislation designed to reduce harmful gas emissions at all points of a product's life cycle - from the production process to its actual end use, right through to final disposal.

The Worcester Bosch Greenstar 8000 Life 50kW has a rating of "A" for heat and "A" for water.

Am I covered if the Worcester Bosch Greenstar 8000 Life 50kW combi boiler breaks down?

The Worcester Bosch Greenstar 8000 Life 50kW boiler comes with a parts and labour warranty lasting 8 years.
