Worcester Bosch Greenstar 8000 Life 45kW Combi Gas boiler frequently asked questions

Is the Worcester Bosch Greenstar 8000 Life 45kW a combi boiler, system boiler or regular boiler?

The Worcester Bosch Greenstar 8000 Life 45kW is an option you may wish to consider if you’re looking for a combi boiler for your house or flat.

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 a Worcester Bosch Greenstar 8000 Life 45kW combi boiler appropriate for my house or apartment?

It's best to choose a boiler whose size or "output" is right for your property. With boilers, however, size does not mean how big a boiler is, it means how much power it has.

A boiler’s output indicates the amount of power it can use when heating the water which it then sends to your taps and radiators. The higher the output rate, the more water it can heat.

If a boiler’s output is too low, there will be times when your hot water might not be as hot as you want it to be. If it is too high, you’ll likely be paying more than you need to for your gas.

Measured in kilowatts, the Worcester Bosch Greenstar 8000 Life 45kW combi's output level is 45 kW, so which types of property would this Worcester Bosch Greenstar 8000 Life 45kW Combi boiler be an appropriate choice for?

An experienced PlumbProud Gas Safe boiler installer would likely recommend that this Worcester Bosch Greenstar 8000 Life 45kW Combi boiler would be suitable for larger properties including detached homes with 15 or more radiators and two or more bathrooms.

When choosing a combi boiler for your home, you need to think about "flow rates" as well as output rates. This Worcester Bosch Greenstar 8000 Life 45kW Combi boiler's flow rate is 16 L/m.

This indicates the maximum volume of hot water (measured in litres per minute) that your boiler can heat then distribute to your taps, showers and radiators at any one time. The greater the demand for hot water in your home, the higher the flow rate you will require.

However, all combi boilers like the Worcester Bosch Greenstar 8000 Life 45kW draw water directly from the mains and heat it instantly.

This means that they can only heat and distribute water at the rate it enters the property (the "mains pressure" rate). For example, if your mains pressure is 11 litres per minute, this will be the highest flow rate you can achieve even if your boiler's flow rate is 17l/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 size is the Worcester Bosch Greenstar 8000 Life 45kW boiler?

The Worcester Bosch Greenstar 8000 Life 45kW is 825 mm tall, 440 mm wide, and 365 mm deep.

Is the Worcester Bosch Greenstar 8000 Life 45kW a non-condensing or condensing boiler?

Because of their increased energy efficiency, we recommend to all customers that they select one of the latest condensing boilers. Condensing boilers capture the heat from water vapour condensation and flue exhaust gases and recycle that heat to warm water entering the boiler (for example, from your radiators).

The Worcester Bosch Greenstar 8000 Life 45kW is a condensing gas boiler and choosing this model will result in a likely substantial reduction in your fuel bills, particularly if you're replacing an older, inefficient, non-condensing boiler.

Is the combi Worcester Bosch Greenstar 8000 Life 45kW boiler energy efficient?

Price and performance are two important issues when choosing a boiler but now, for many people in the UK, so is the environmental impact of how we heat our homes and its effect on climate change.

In the UK, central heating systems account for 14% of greenhouse gas production. Gas boilers in particular are responsible for emissions of dangerous nitrogen dioxide in British cities.

Will installing a Worcester Bosch Greenstar 8000 Life 45kW combi be a positive contribution to the environment? Let's see what the experts say.

Boilers manufactured in the UK must be tested and, by law, achieve an energy efficiency rating of 92% or above, equivalent to a SEDBUK "A" grade. Most boilers achieve an "A" rating meaning they are at least 88% efficient.

The energy efficiency of a boiler indicates the amount of energy it uses (and wastes) during operation.

The Worcester Bosch Greenstar 8000 Life 45kW has been assigned an efficiency rating of 94% with a SEDBUK rating of "A".

The Energy Related Products Directive grades products according to the energy they consume and the harmful gas emissions they create, from manufacturing right through to final disposal, including how they're used by customers between these two points.

The Worcester Bosch Greenstar 8000 Life 45kW is rated "A" for heat and "A" for water.

What warranty do I get if I purchase the Worcester Bosch Greenstar 8000 Life 45kW boiler?

The Worcester Bosch Greenstar 8000 Life 45kW boiler comes with a 8 year warranty for parts and labour.

Worcester Bosch Greenstar 8000 Life 45kW Combi Gas boiler frequently asked questions

What type of boiler is Worcester Bosch’s Greenstar 8000 Life 45kW - system, regular or combi?

You might want to consider the Worcester Bosch Greenstar 8000 Life 45kW for your house or flat if you are looking for a combi boiler.

One of the reasons the combi boiler was introduced to Britain in the 1970s was because residential properties are among the smallest in the world. More traditional boilers require one or more large tanks to be stored around the home to function.

A combi boiler is a self-contained unit that draws water from the mains then heats and distributes it instantly and on demand - no tanks are needed.

They are the most popular type of boilers in the UK and offer only one major disadvantage - there is a maximum volume of water that can be heated at any one time. If that limit is exceeded by, for example, two people using a hot water tap at the same time, there will be a drop in water pressure, temperature and volume to both taps.

Is a Worcester Bosch Greenstar 8000 Life 45kW combi boiler suitable for my house or apartment?

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 - the "output".

The output of a boiler is measured in kilowatts. The output level determines the maximum power a boiler can use in heating the water needed for the baths, showers, taps and radiators in your home.

It's important to choose a boiler with an appropriate level of output for your property. Your boiler should be able to cope with periods of peak demand in your property and not just your average usage.

An output rate that is too low will result in an inadequate supply of hot water, while an output that is too high will mean the boiler will cost more to run than is necessary.

The output of the Worcester Bosch Greenstar 8000 Life 45kW combi is 45 kW kilowatts, so which types of property would this be appropriate for?

A heating engineer would recommend that this Worcester Bosch Greenstar 8000 Life 45kW Combi boiler would provide adequate heating and hot water for larger properties including detached homes with up to 15 or more radiators and two or more bathrooms.

With all combi boilers, you need to consider the "flow rate" as well as the output rate when making your decision.

Like all combi boilers, the Worcester Bosch Greenstar 8000 Life 45kW 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. This Worcester Bosch Greenstar 8000 Life 45kW Combi boiler's flow rate is 16 L/m.

There is no benefit to purchasing a boiler with a high flow rate if the local water pressure is not that good - a high flow rate doesn't mean that your combi can draw more water from the mains.

In addition, if you live in a home with a large number of radiators and more than one bathroom and if more than one person regularly wants to use hot water at a time, a combi boiler may struggle to provide enough water at a hot enough temperature.

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 Life 45kW

The dimensions of the Worcester Bosch Greenstar 8000 Life 45kW are 825 mm tall, 440 mm wide, and 365 mm deep.

Is the Worcester Bosch Greenstar 8000 Life 45kW condensing or non-condensing?

Because of their increased energy efficiency, we recommend to all customers that they select one of the latest condensing boilers. Condensing boilers capture the heat from water vapour condensation and flue exhaust gases and recycle that heat to warm water entering the boiler (for example, from your radiators).

The Worcester Bosch Greenstar 8000 Life 45kW is a condensing gas boiler and choosing this model will result in a likely substantial reduction in your fuel bills, particularly if you're replacing an older, inefficient, non-condensing boiler.

What energy efficiency ratings have been awarded to the Worcester Bosch Greenstar 8000 Life 45kW combi?

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.

About 14% of the greenhouse gases we produce in the UK come from the power needed for central heating. In bigger British cities, gas boilers are a significant source of nitrogen dioxide emissions.

Would installing a Worcester Bosch Greenstar 8000 Life 45kW combi boiler in your home help combat climate change? What do the figures suggest?

All boilers manufactured in the UK from April 2018 must achieve a SEDBUK “A” grade and an energy efficiency rating of 92% or above. Before that, the minimum was 88% - efficiency ratings of 88% and 89% were scored a “B” and 90%+ an "A".

A boiler's energy efficiency rating describes how much energy it uses and wastes during its standard operation.

The energy efficiency of the Worcester Bosch Greenstar 8000 Life 45kW was rated at 94% with a SEDBUK grading of "A".

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 Life 45kW has an ERP rating of "A" for heat and "A" for hot water production.

What is the length of the warranty on the Worcester Bosch Greenstar 8000 Life 45kW?

A parts and labour warranty of 8 years is included with the Worcester Bosch Worcester Bosch Greenstar 8000 Life 45kW boiler.
