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

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

If you want a combi boiler for your flat or house, the Worcester Bosch Greenstar 8000 Life 50kW might be an option for you to consider.

Traditional boilers would require you to install one or more storage tanks in your property. These tanks either kept the water warm or stored it for later heating. Manufacturers initially designed and introduced combi boilers to the market to offer homeowners the highest levels of warmth and unlimited hot water without taking up as much space.

Combi boilers provide hot water on demand for your radiators and taps. They take water directly from the mains, heat it immediately as it's needed, and then distribute the hot water around your home.

Combi boilers, however, are limited in terms of how much water they can heat at any given time. For example, if one person wishes to take a shower while another wants to turn on a hot water tap, the amount of water reaching each point drops. This results in a drop in the water pressure as well as the temperature.

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

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

The amount of hot water you get from showers, bathrooms, and sinks and heat from your radiators depends on your boiler's output (measured in kilowatts). The higher the level of output, the better your home will be heated and you can be more certain that the water from your taps will be as hot as you want.

However, you must be careful. You might not get the hot water you want if your boiler output is too low. If it's too high, you'll be paying more than you need to for gas.

With the Worcester Bosch Greenstar 8000 Life 50kW combi's output at 50 kW, which types of property would this Worcester Bosch Greenstar 8000 Life 50kW Combi boiler be most appropriate for?

An experienced Gas Safe engineer would say that this Worcester Bosch Greenstar 8000 Life 50kW Combi boiler's level of output makes it suitable for installing in larger properties including detached homes with 15 or more radiators and two or more bathrooms.

When choosing a combi boiler like the Worcester Bosch Greenstar 8000 Life 50kW, you need to consider the "flow rate" as well as the output rate. Flow rates (measured in litres per minute) indicate the volume of hot water that the boiler can heat up and then distribute to your taps and radiators.

However, combi boilers draw water from the mains and this means they can only heat the amount of water that actually enters your property.

What this means is that, if your mains pressure is 12 litres per minute, that is your boiler's effective flow rate even if it has the capacity to process 18 litres per minute. This Worcester Bosch Greenstar 8000 Life 50kW Combi boiler's flow rate is 18 L/m.

To give you an idea of the flow rate you might need, a power shower typically requires around 12 litres of water per minute and a basin tap requires 4-8 litres per minute.

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 is the size of the Worcester Bosch Greenstar 8000 Life 50kW?

The Worcester Bosch Greenstar 8000 Life 50kW occupies a space of 825 mm high by 440 mm wide and 365 mm deep.

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

The Worcester Bosch Greenstar 8000 Life 50kW is a condensing gas boiler - we strongly suggest that you choose either this model or a recently released model if at all possible.

A condensing boiler captures and recycles the warmth present in flue exhaust gases and water vapour condensation created by the burning of gas to warm up the water coming back into your boiler - for example, from your radiators.

Condensing boilers cost less to run (lower gas bills) and are better for the environment.

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

Environmentally-friendly heating has become an important issue for homeowners concerned about the accelerating pace of 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 50kW combi be a positive contribution to the environment? Let's see what the experts say.

By law, the minimum level of energy efficiency for boilers manufactured in the UK is 92%, equivalent to a good SEDBUK “A” rating. Prior to April 2018, the minimum was 88% - boilers whose energy efficiency levels were 88% or 89% were given a "B" rating on the SEDBUK scale and those at 90% or higher were given an "A".

The energy efficiency rating awarded to each boiler indicates the amount of energy that is wasted when in operation.

Following testing, the Worcester Bosch Greenstar 8000 Life 50kW was given a 94% energy efficiency rating and a SEDBUK grading of "A".

Energy-efficient boilers help the environment as they require less fuel and emit fewer harmful gases. In 2015, the EU introduced the Energy Related Products Directive (ERP), the aim of which was to ensure that all manufacturers, including boiler manufacturers, developed more efficient products and processes.

The legislation aims to conserve energy at all life cycle stages from initial production to actual use by the customer, through to the point of disposal.

The Worcester Bosch Greenstar 8000 Life 50kW has been given an ERP rating of "A" for heat and "A" for water.

What is the warranty period for the Worcester Bosch Greenstar 8000 Life 50kW?

You receive a parts and labour warranty of 8 years with the Worcester Bosch Greenstar 8000 Life 50kW boiler.

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

What kind of boiler is the Worcester Bosch Greenstar 8000 Life 50kW - standard, combi or system?

You may wish to consider installing the Worcester Bosch Greenstar 8000 Life 50kW if you are looking for a combi boiler for your house or flat.

Traditional boilers have one or two tanks - one holds hot water to keep it warm and the other water for later heating. Because UK residential property is among some of the smallest in the world, manufacturers introduced combi boilers and the heat pumps that go in them in the 1970s to reduce the amount of space boilers needed to take up.

The hot water needed for your radiators and taps is available on demand when you have a combi boiler. Combi boilers use technology located within the boiler to heat cold water, which it draws from the mains, and to distribute hot water where it's needed around your home.

A combi boiler, however, has the disadvantage of a maximum capacity for the amount of water it can heat. The result is that if someone uses the shower while another uses a hot water tap simultaneously, the amount of water reaching each point falls, causing water pressure to drop.

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

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

The amount of hot water you get from showers, bathrooms, and sinks and heat from your radiators depends on your boiler's output (measured in kilowatts). The higher the level of output, the better your home will be heated and you can be more certain that the water from your taps will be as hot as you want.

However, you must be careful. You might not get the hot water you want if your boiler output is too low. If it's too high, you'll be paying more than you need to for gas.

With the Worcester Bosch Greenstar 8000 Life 50kW combi's output at 50 kW, which types of property would this Worcester Bosch Greenstar 8000 Life 50kW Combi boiler be most appropriate for?

An experienced Gas Safe boiler installer would recommend that this Worcester Bosch Greenstar 8000 Life 50kW Combi boiler would be a suitable installation choice 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 Life 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.


What size is the Worcester Bosch Greenstar 8000 Life 50kW boiler?

The Worcester Bosch Greenstar 8000 Life 50kW boiler is 825 mm high, 440 mm wide, and 365 mm deep.

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

We recommend that you select a condensing boiler like the Worcester Bosch Greenstar 8000 Life gas Worcester Bosch Greenstar 8000 Life 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 energy efficient is the Worcester Bosch Greenstar 8000 Life 50kW combi?

As more of us are increasingly concerned about climate change, how we heat our homes and its impact on the environment has become an issue of importance to homeowners.

We generate 14% of UK greenhouse gas emissions through centrally heating our domestic properties. Gas boilers are mainly responsible for harmful nitrogen dioxide emissions in larger British cities.

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.

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 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 50kW, the ERP rating is "A" for heat and "A" for hot water production.

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

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