Worcester Bosch Greenstar Danesmoor External 18/25 heat only Oil boiler frequently asked questions

Is the Worcester Bosch Greenstar Danesmoor External 18/25 a combi boiler, system boiler or regular boiler?

If you are considering installing a heat only boiler in your house or flat, then the Worcester Bosch Greenstar Danesmoor External 18/25 boiler is certainly worth investigating.

A heat only boiler, sometimes called a conventional boiler, a standard boiler or a regular boiler, requires both a hot water cylinder and a cold water tank to operate. Most homeowners keep their hot water cylinder in a landing cupboard or airing cupboard and their cold water tank in the attic. Your hot water is kept warm in the immersion cylinder.

With a heat only boiler, you program your hot water and temperature for set times during the day or week. If you forget to set your boiler or the immersion cylinder runs out of hot water, you may have to wait up to an hour for your supply of hot water to be restored.

A heat only boiler is likely to be the best choice for a home with several bathrooms or a bigger family - the type of household where hot water is in continual demand and more than one person might need it at once. With the more popular combi boiler, there is a maximum amount of water that can be heated and distributed, while pressure, volume and temperature drop if two or more people need hot water at once.

Is the Worcester Bosch Greenstar Danesmoor External 18/25 heat only boiler from the Greenstar Danesmoor External range a suitable choice for my house or flat?

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

The output rate of a boiler tells you how much power it has available to it for heating the water that comes out of your taps and warms your radiators. A higher output rate means that your boiler has more power at its disposal.

You need to make sure you select a boiler with the right output rate. That's because, if your output rate is too high, then your boiler will have more power than it needs but it will cost too much to run. If the output rate is too low, your water may often not be hot enough.

The Worcester Bosch Greenstar Danesmoor External 18/25 heat only's output is 25 kW, so which types of property would this Worcester Bosch Greenstar Danesmoor External 18/25 heat only boiler be appropriate for?

An experienced PlumbProud Gas Safe boiler installer would recommend that this Worcester Bosch Greenstar Danesmoor External 18/25 heat only boiler is suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


What are the dimensions of the Worcester Bosch Greenstar Danesmoor External 18/25 boiler?

The Worcester Bosch Greenstar Danesmoor External 18/25 measures 950 mm tall, 565 mm wide, and 600 mm deep.

Floor-standing external heat only boilers like the Worcester Bosch Greenstar Danesmoor External 18/25 are housed in a strong weatherproof casing that protects them from rust and water ingress - they also offer much easier access for heating engineers if there is a fault or a repair is needed.

The risk of internal oil leaks and the damage and unpleasant odours they cause is also removed, as is the threat to your family's safety in the event of a carbon monoxide escape (the gas will simply disperse harmlessly into the atmosphere).

Is the Worcester Bosch Greenstar Danesmoor External 18/25 non-condensing or condensing?

We recommend that, if possible, you choose a condensing boiler like the Worcester Bosch Greenstar Danesmoor External 18/25.

Condensing boilers are more energy-efficient. They achieve this efficiency by capturing the heat present in flue exhaust gases and water vapour condensation and recycling that heat to, for example, warm colder water coming back from your radiators.

By choosing the latest condensing boiler, you'll also notice a significant reduction in your oil bills, particularly if you're replacing a boiler more than 15 years old.

Is the Worcester Bosch Greenstar Danesmoor External 18/25 heat only considered environmentally friendly?

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.

Central heating produces 14% of all greenhouse gas emissions in the UK. Gas boilers in the larger cities emit dangerous levels of nitrogen dioxide.

Will installing a Worcester Bosch Greenstar Danesmoor External 18/25 heat only 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 Danesmoor External 18/25 was given a 90% energy efficiency rating and a SEDBUK grading 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 Danesmoor External 18/25 is rated "A".

How many years does the warranty period cover on a Worcester Bosch Greenstar Danesmoor External 18/25 boiler?

The Worcester Bosch Greenstar Danesmoor External 18/25 boiler offers a parts and labour warranty of 2 years.

Worcester Bosch Greenstar Danesmoor External 18/25 heat only Oil boiler frequently asked questions

What type of boiler is Worcester Bosch’s Greenstar Danesmoor External 18/25 - system, regular or combi?

The Worcester Bosch Greenstar Danesmoor External 18/25 may be worth considering if you are looking for a heat only boiler for your house or flat.

You may hear a heat only boiler being called a regular boiler, a conventional boiler or a standard boiler. With a regular boiler, you need to find room within your property for a hot water cylinder with an immersion heater (usually in a landing cupboard or airing cupboard) and a cold-water tank (usually in the loft). The immersion cylinder is what keeps your hot water warm all day.

With a regular boiler, you schedule your hot water and heating for set times during the day or week, but if you forget to do so and the hot water runs out, you'll need to wait for your boiler to heat enough water before you can have a bath or shower - that can sometimes take up to an hour.

A regular boiler is suitable for homes with more than one bathroom or larger families when there is high demand for hot water. Although combi boilers are the most popular type of boiler in Britain, water pressure, volume and temperature drop if there is simultaneous demand from two or more points - for example, someone running a hot water tap when someone else is in the shower.

Should I install a Worcester Bosch Greenstar Danesmoor External 18/25 heat only boiler in my home?

You should make sure that the boiler you choose for your property is the right "size". And size doesn't mean its physical dimensions. Size means how much power it has - the "output".

A boiler's output level measures how much power it can use to provide you with the hot water you need for your radiators and taps. If a boiler has a high output rate, it can heat greater volumes of water.

If you choose a boiler with too low an output, you'll find that the water coming out of your taps and in your radiators won't be as hot as you want it to be. Choosing one whose output is too high means you'll pay more than you need to for the oil your boiler needs to work.

The Worcester Bosch Greenstar Danesmoor External 18/25 heat only outputs at a maximum of 25 kW, so which types of property would this Worcester Bosch Greenstar Danesmoor External 18/25 heat only boiler be appropriate for?

An experienced PlumbProud Gas Safe boiler installer would recommend that this Worcester Bosch Greenstar Danesmoor External 18/25 heat only boiler is suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


What size is the Worcester Bosch Greenstar Danesmoor External 18/25 boiler?

The Worcester Bosch Greenstar Danesmoor External 18/25 measures 950 mm in height by 565 mm in width by 600 mm in depth.

The Worcester Bosch Greenstar Danesmoor External 18/25 boiler is an external, floor-standing heat only boiler benefiting from sturdy weatherproof housing that provides reliable protection from the UK’s changeable weather, rusting, and water ingress.

Because they're installed outdoors, you save valuable space inside your home and you'll never hear the boiler in operation. An external boiler is also much easier for a service engineer to access if it breaks down or needs repair.

External boilers cut the risk of carbon monoxide leaking into your home and, because the oil it uses for power is stored outside, you greatly reduce the potential for indoor oil leakages which often cause severe damage as well as unpleasant odours that can be very hard to get rid of.

Is the Worcester Bosch Greenstar Danesmoor External 18/25 condensing or non-condensing?

We recommend that you choose a condensing boiler wherever possible like the Worcester Bosch Greenstar Danesmoor External 18/25 - 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 oil to make them more efficient and economical to run.

You will save money on your oil bills too, plus condensing boilers are friendlier to the environment.

How environmentally friendly is the Worcester Bosch Greenstar Danesmoor External 18/25 heat only?

How we heat our homes and the damage we might be doing to the environment as a result has become an important point of concern to many homeowners worried about climate change.

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.

Will choosing a Worcester Bosch Greenstar Danesmoor External 18/25 heat only boiler for your home be positive for the environment? Let's examine the figures.

The Worcester Bosch Greenstar Danesmoor External 18/25 has been awarded an efficiency rating of 90% and a SEDBUK band rating of "A".

In the UK, all boilers manufactured and supplied must have an energy efficiency rating of at least 92% or a SEDBUK "A" grade. Until April 2018, the minimum rating was 88% (88% and 89% are equivalent to a SEDBUK "B" rating and anything higher is rated "A").

A boiler's energy efficiency rating describes the amount of energy it uses and wastes when in normal operation.

The Energy Related Products Directive intends to encourage all manufacturers to reduce harmful gas emissions connected to the products they make, from the manufacturing stage to final disposal, including when they are in active use.

The Worcester Bosch Greenstar Danesmoor External 18/25 has an ERP rating of "A".

What is the warranty period for the Worcester Bosch Greenstar Danesmoor External 18/25?
