Worcester Bosch Greenstar 8000 Life 40kW Combi Gas boiler frequently asked questions

What kind of boiler is the Worcester Bosch Greenstar 8000 Life 40kW - standard, combi or system?

If you’re looking for a combi boiler for your house or flat, you may wish to the consider the Worcester Bosch Greenstar 8000 Life 40kW.

A combi boiler could be a better choice than a standard boiler if space is at a premium in your home. Combi boilers draw water directly from the mains supply and heat it instantly, removing the need for a hot water cylinder and a cold water tank.

Water is heated on demand and then distributed directly to your taps and showers. This means that combi boilers use less fuel and so reduce your gas bills.

The main disadvantage to combi boilers is that they can only heat a limited volume of water at any given time. If more than one tap or shower is in use, the hot water supply to both could be restricted and both the water pressure and temperature will drop.

Would the Worcester Bosch Greenstar 8000 Life 40kW combi boiler be suitable for my house or flat?

Whether this Worcester Bosch Greenstar 8000 Life 40kW 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 Life 40kW combi is 40 kW, so which types of property is this Worcester Bosch Greenstar 8000 Life 40kW Combi boiler appropriate for?

A PlumbProud heating engineer would recommend that this Worcester Bosch Greenstar 8000 Life 40kW Combi boiler be installed in 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 Life 40kW Combi boiler's flow rate is 16 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.


What size is the Worcester Bosch Greenstar 8000 Life 40kW boiler?

The dimensions of the Worcester Bosch Greenstar 8000 Life 40kW are 825 mm tall, 440 mm wide, and 365 mm deep.

Is the Worcester Bosch Greenstar 8000 Life 40kW condensing or non-condensing?

The Worcester Bosch Greenstar 8000 Life 40kW 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.

What energy efficiency ratings have been awarded to the Worcester Bosch Greenstar 8000 Life 40kW combi?

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

14% of the UK’s greenhouse gas production comes from central heating. In the bigger cities, gas boilers in particular are responsible for dangerous levels of nitrogen dioxide emissions.

Is the Worcester Bosch Greenstar 8000 Life 40kW combi boiler an environmentally friendly choice for your home? Here’s what the figures say.

By law, boilers manufactured and supplied in the UK must achieve a SEDBUK rating of "A" and work at a 92% minimum efficiency. Before April 2018, a minimum of 88% energy efficiency needed to be achieved (88/89% = SEDBUK "B" and 90% = SEDBUK "A").

Following official testing, the Worcester Bosch Greenstar 8000 Life 40kW was given an efficiency rating of 94% with a SEDBUK rating of "A".

Energy efficiency is a measure of how much energy is used and how much is wasted when a boiler is operating.

The ERP (or Energy Related Products Directive) is a European regulation governing products which require energy to operate throughout their lives and encourages manufacturers to create products that are more environmentally friendly.

The legislation is designed to reduce the potential for harmful gas emissions during manufacturing and actual use right through to the point of final disposal.

For the Worcester Bosch Greenstar 8000 Life 40kW, the ERP rating is "A" for heat and "A" for hot water production.

Is this Worcester Bosch Greenstar 8000 Life 40kW combi covered by a warranty?

The Worcester Bosch Greenstar 8000 Life 40kW boiler comes with a parts and labour warranty of 8 years.

Worcester Bosch Greenstar 8000 Life 40kW Combi Gas boiler frequently asked questions

Which category of boiler does the Worcester Bosch Greenstar 8000 Life 40kW fit into?

If you want a combi boiler for your flat or house, the Worcester Bosch Greenstar 8000 Life 40kW might be an option for you to consider.

Traditional boilers have one or more large tanks in which they store either heated water or water to be heated later. Manufacturers originally introduced combi boilers to the market in the 1970s to enable homeowners to save space - UK residential properties are among the smallest in the Western world.

Combi boilers don't need these tanks because they draw water directly from the mains and instantly heat it on demand thanks to the technology inside the boiler. Combi boilers then distribute this hot water to your home’s taps and radiators when needed.

The most significant disadvantage of combi boilers is that they are not ideal in larger homes where multiple people might want hot water at the same time – for example, if someone is having a shower while another wants to wash dishes in the kitchen. This is because combi boilers have a maximum volume of water that they can heat. When two people want hot water at the same time, the water temperature, pressure and volume delivered to both points drop.

Should I install a Worcester Bosch Greenstar 8000 Life 40kW combi boiler in my house or apartment?

It's best to choose a boiler whose size or "output" is right for your home.

The more hot water and heat you want, the higher the output level of your boiler should be. Output is measured in kilowatts and it describes the maximum level of power your boiler has to heat water.

If your output level is too low, your boiler will not have the power it needs to get your water as hot as you want it, particularly when there's a lot of demand for it. Choose a boiler whose output level is too high and you'll have all the hot water you need but will be paying too much for it through higher gas bills.

Which types of property would this Worcester Bosch Greenstar 8000 Life 40kW Combi boiler be appropriate for given its output of 40 kW?

Most Gas Safe boiler installers would suggest that the most suitable type of property for installing this Worcester Bosch Greenstar 8000 Life 40kW Combi boiler in would be larger properties including detached homes with 15 or more radiators and two or more bathrooms.

With combi boilers, flow rates are as important a consideration as output rates.

All combi boilers draw water from the mains. They then heat this water instantly whenever it's needed and distribute it to your radiators and taps.

A boiler's "flow rate" describes how much water a boiler can draw from the mains at any one time, which it then heats and sends around your home (measured in litres per minute). This Worcester Bosch Greenstar 8000 Life 40kW Combi boiler's flow rate is 16 L/m.

If your home has a large number of radiators, a lot of bathrooms, or multiple people who wish to use the hot water at the same time, your combi boiler may not be able to draw as much water from the mains as it needs to serve everyone, regardless of how high the flow rate is.

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 Life 40kW have?

The Worcester Bosch Greenstar 8000 Life 40kW boiler is 825 mm high, 440 mm wide, and 365 mm deep.

Is the Worcester Bosch Greenstar 8000 Life 40kW condensing or non-condensing?

We recommend that you choose a condensing boiler wherever possible like the Worcester Bosch Greenstar 8000 Life 40kW - 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.

Is the combi Worcester Bosch Greenstar 8000 Life 40kW boiler energy efficient?

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.

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 a Worcester Bosch Greenstar 8000 Life 40kW combi boiler in your home help combat climate change? What do the figures suggest?

In the UK, by law, all boilers manufactured since April 2018 must have a SEDBUK “A” rating and operate to a minimum level of 92% energy efficiency. Prior to this, the minimum was 88% – 88/89% would score a "B" and 90% or more an "A" on the SEDBUK scale.

The energy efficiency rating measures the amount of energy a boiler consumes when it's in use and how much it loses on non-core operations.

Following testing, the Worcester Bosch Greenstar 8000 Life 40kW was given an efficiency rating of 94% and a SEDBUK grading 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 Life 40kW is "A" for heat and "A" for water.

How long is the warranty period on a Worcester Bosch Greenstar 8000 Life 40kW combi boiler?

The Worcester Bosch Greenstar 8000 Life 40kW boiler is covered by a parts and labour warranty of 8 years.
