Worcester Bosch Greenstar Danesmoor External System 12/18 System Oil boiler frequently asked questions

Which category of boiler does the Worcester Bosch Greenstar Danesmoor External System 12/18 fit into?

If you want a system boiler for your flat or house, the Worcester Bosch Greenstar Danesmoor External System 12/18 might be an option for you to consider.

Like heat only boilers, system boilers need a hot water cylinder to work - they're normally installed inside an airing or landing cupboard. However, since system boilers do not require a separate cold water tank, they are popular with homeowners who are planning to convert their loft or where attic space is already at a premium.

They're able to distribute the hot water you need to taps and radiators through (often built-in) circulating pumps and, because there's no water tank to install, they're easier, quicker and cheaper to install than heat only boilers. To get the heat and hot water you need when you need it, just use the control panel to program the times and days you want.

Is the Worcester Bosch Greenstar Danesmoor External System 12/18 system boiler the right choice for my house or apartment?

You should make sure that the boiler you install in your property is the right "size". And, by size, we don't mean how big it is, we mean how powerful it is - the "output".

Your boiler has to be powerful enough to heat all the hot water you need for your radiators and taps. Power is measured in kilowatts and the more kilowatts a boiler has available to it, the more water it can heat.

If the output (measured in kilowatts) is too high, you'll have all the power you need and more but your oil bills will be much higher. If it's too low, you'll often find that the water coming out of your taps and fed into your radiators is only lukewarm.

With the Worcester Bosch Greenstar Danesmoor External System 12/18 system's output at 18 kW, which types of property would this Worcester Bosch Greenstar Danesmoor External System 12/18 System boiler be most appropriate for?

A PlumbProud Gas Safe engineer would recommend that the most suitable type of property for a Worcester Bosch Greenstar Danesmoor External System 12/18 system would be smaller homes and apartments containing up to 10 radiators and providing hot water for one bathroom.


Dimensions of the Worcester Bosch Greenstar Danesmoor External System 12/18 boiler

The Worcester Bosch Greenstar Danesmoor External System 12/18 is 950 mm [H] by 565 mm [W] by 780 mm [D] in size.

External, floor-standing system boilers like the Worcester Bosch Greenstar Danesmoor External System 12/18 are installed outdoors saving you valuable space inside your home as well as protecting you from the noise made by a oil boiler during its operation.

Supplied in sturdy, weatherproof housing that protects it from rusting and water ingress, external boilers are much easier for heating engineers to gain access to in case of repair or on maintenance visits.

Because the boiler is not inside your property, carbon monoxide fumes escape into the atmosphere if there is a leak. In addition, there's little to no chance of oil getting into your home if the boiler malfunctions - oil spills inside your property can cause significant damage and leave unpleasant odours that can be very hard to shift.

Is the Worcester Bosch Greenstar Danesmoor External System 12/18 non-condensing or condensing?

The Worcester Bosch Greenstar Danesmoor External System 12/18 is a condensing oil boiler - we strongly recommend that you choose one of the latest condensing models if possible.

With a condensing boiler, you save money on your oil bills because your boiler captures and recycles the heat present in the flue exhaust gases and water vapour condensation for re-use, meaning they operate far more economically and efficiently.

Is the Worcester Bosch Greenstar Danesmoor External System 12/18 system environmentally friendly?

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.

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.

Is the Worcester Bosch Greenstar Danesmoor External System 12/18 system an environmentally friendly choice for your home? Let’s have a look at the figures.

Under current UK law, all boilers must achieve a minimum energy efficiency level of 92% (a low to good SEDBUK "A" rating). The minimum level was raised from its previous 88% in April 2018.

Energy efficiency scores are intended to inform consumers of the amount of energy used and wasted when a boiler is in normal operation.

The Worcester Bosch Greenstar Danesmoor External System 12/18 was awarded an efficiency rating of 90% with a SEDBUK band rating of "A".

In 2015, the Energy Related Products Directive (ERP) came into force. The legislation applies to all products that consume energy - in production, during their active life, and at the point of final disposal.

The ERP was introduced to incentivise manufacturers to create products that emit fewer harmful gases with the larger aim of protecting the wider environment.

The Worcester Bosch Greenstar Danesmoor External System 12/18 has been awarded an ERP rating of "A".

What is the length of the warranty on the Worcester Bosch Greenstar Danesmoor External System 12/18?

The Worcester Bosch Greenstar Danesmoor External System 12/18 boiler comes with a parts and labour warranty lasting 2 years.

Worcester Bosch Greenstar Danesmoor External System 12/18 System Oil boiler frequently asked questions

What type of boiler is the Worcester Bosch Greenstar Danesmoor External System 12/18 - regular, system or combi?

The Worcester Bosch Greenstar Danesmoor External System 12/18 is a system boiler you may wish to consider if you want this particular type of boiler for your house or flat.

System boilers require a hot water cylinder to work (normally stored in an airing or landing cupboard) but, unlike heat only boilers, they do not require a cold water tank. This makes them more suitable for homes that do not have lofts, where attic space is limited or where a loft conversion is being considered.

You program your heating and hot water to come on via the control panel. But if you forget to set the timer, you will have to wait a while for the water to heat up. Hot water is stored in the cylinder for use throughout the day and can be distributed to multiple showers and taps at the same time without a loss of pressure or temperature (something combi boilers really struggle with). For this reason, a system boiler is a suitable option for large families and homes with more than one bathroom.

As no cold-water tank is needed with a system boiler and many major system components are built into it, this type of boiler can be easier to install than a standard boiler.

Would the Worcester Bosch Greenstar Danesmoor External System 12/18 system be a suitable boiler for my house or flat?

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 Danesmoor External System 12/18 system is 18 kW kilowatts, so which types of property would this be appropriate for?

A boiler engineer would recommend that, at this level of output, the most suitable type of property for this Worcester Bosch Greenstar Danesmoor External System 12/18 System boiler would be smaller homes and apartments with up to 10 radiators and one bathroom.


What size is the Worcester Bosch Greenstar Danesmoor External System 12/18 boiler?

Worcester Bosch’s Greenstar Danesmoor External System 12/18 is 950 mm tall, 565 mm wide, and 780 mm deep.

Floor-standing external system boilers like the Worcester Bosch Greenstar Danesmoor External System 12/18 are housed in a sturdy weatherproof casing to protect them from the elements, water ingress, and the risk of rust. Heating engineers also find external boilers much easier to access on repair and maintenance visits.

As the boiler is outdoors, there is less risk of an oil leakage into your home that can cause significant damage and leave your property with an unpleasant, hard-to-remove odour. In addition, there is far less danger to you and your family from carbon monoxide leakage as, in the event of a fault, the gas will disperse in the outside atmosphere.

Is the Worcester Bosch Greenstar Danesmoor External System 12/18 a condensing or non-condensing boiler?

Condensing boilers like the Worcester Bosch Greenstar Danesmoor External System 12/18 improve energy efficiency and reduce your annual expenditure on oil.

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.

How energy efficient is the Worcester Bosch Greenstar Danesmoor External System 12/18 system?

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

14% of the total amount of greenhouse gases produced by the UK comes from the central heating systems we use. In some of Britain's biggest cities, gas boilers create dangerous levels of nitrogen dioxide in the atmosphere.

Do the figures suggest that installing the Worcester Bosch Greenstar Danesmoor External System 12/18 system at your property would help in the fight against climate change?

The energy efficiency rating for a boiler describes the amount of energy it uses and wastes during operation and there are two different ways to measure it.

All boilers manufactured and supplied in the UK must have a SEDBUK rating of “A” subject to a minimum energy efficiency score of 92% or above. Before April 2018, the minimum energy efficiency score was 88% (88/89% = "B" SEDBUK rating, 90%+ = "A" SEDBUK rating).

The Worcester Bosch Greenstar Danesmoor External System 12/18 scored an efficiency rating of 90% and a SEDBUK band rating of A.

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, and right through to the point of final disposal.

The Worcester Bosch Greenstar Danesmoor External System 12/18 has a rating of "A" .

How many years does the warranty period cover on a Worcester Bosch Greenstar Danesmoor External System 12/18 boiler?

You receive a parts and labour warranty of 2 years with the Worcester Bosch Greenstar Danesmoor External System 12/18 boiler.
