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, system or regular boiler?

The Worcester Bosch Greenstar Danesmoor External 18/25 is a heat only boiler you may wish to consider if you want this type of boiler for your house or flat.

Heat only boilers are sometimes called standard boilers, regular boilers or conventional boilers but they are actually the same thing. For a heat only boiler, you'll need to find space for both a cold-water tank and an immersion hot water cylinder - most households choose the attic for the former and a landing cupboard or airing cupboard for the latter. The immersion cylinder is the part of the system that keeps your hot water warm.

You program your boiler to provide you with the hot water you want at certain times, such as when you want to have a bath or a shower. However, if you don't remember to program your boiler, you'll have to wait for it to heat up if the hot water has run out.

A regular boiler is the most suitable choice if you have a larger family or if there is more than one bathroom in your home - the more popular combi boilers do not work well in homes where there is high and often simultaneous demand for hot water.

Is the Worcester Bosch Greenstar Danesmoor External 18/25 heat only boiler the right choice for my house or apartment?

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 boiler engineer would recommend that this Worcester Bosch Greenstar Danesmoor External 18/25 heat only boiler would provide adequate heating and hot water for medium-sized homes and larger apartments with up to 10-15 radiators and two bathrooms.


How big is the Worcester Bosch Greenstar Danesmoor External 18/25?

The Worcester Bosch Greenstar Danesmoor External 18/25 has the following dimensions - 950 mm high, 565 mm wide, and 600 mm deep.

External, floor-standing heat only boilers like the Worcester Bosch Greenstar Danesmoor External 18/25 provide homeowners with more indoor space (they're installed outdoors) and reduce noise pollution (you can't really hear them from inside your house). They are also easier for engineers to work on if needed, while carbon monoxide leaks are less likely to pose a safety threat to your family because the gas disperses outside.

This model's weatherproof housing ensures protection from the British climate, reducing the likelihood of water ingress and rusting. And, since the oil is stored outdoors, there is minimal risk of leakage occurring inside your home that can cause significant damage as well as unpleasant odours which are hard to eliminate.

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

The Worcester Bosch Greenstar Danesmoor External 18/25 is a condensing oil boiler - in fact, we recommend that you select this model or one of the latest condensing boilers on the market as the technology continues to improve over time.

Condensing boilers capture the heat still present in the flue exhaust gases and water vapour condensation created when the oil is burned and they recycle this back into the heating system to warm up the cold water re-entering the boiler from your radiators.

They're much more environmentally friendly and installing one results in much lower annual oil bills.

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

How we heat our homes and the damage this does to the environment has become a pressing concern for many homeowners worried about the effects and impact of climate change.

Dangerous levels of nitrogen dioxide emissions in larger UK cities are caused by gas boilers in domestic properties, and 14% of the UK’s greenhouse gas production is as a result of central heating.

Will you be helping the environment if you decide to install a Worcester Bosch Greenstar Danesmoor External 18/25 heat only in your home? Let’s look at the figures.

All boilers manufactured and supplied in the UK must achieve an energy efficiency rating of at least 92% (an "A" SEDBUK grade). This is higher than the previous 88%, which was a legal requirement prior to April 2018.

The energy efficiency rating is used to work out how much energy a boiler both uses and wastes when it's switched on and working correctly - its standard functioning and operation.

The Worcester Bosch Greenstar Danesmoor External 18/25 is rated as 90% energy efficient, equivalent to a "A" SEDBUK rating.

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 18/25 has been awarded an ERP rating of "A".

How many years' warranty does the Worcester Bosch Greenstar Danesmoor External 18/25 heat only come with?

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

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

What kind of boiler is the Worcester Bosch Greenstar Danesmoor External 18/25 - standard, combi or system?

When looking for a heat only boiler for your house or flat, the Worcester Bosch Greenstar Danesmoor External 18/25 might be a suitable option for you.

Heat only boilers are also referred to as regular boilers, conventional boilers or standard boilers. Heat only boilers require both a hot water/immersion cylinder (usually stored in a landing cupboard or airing cupboard) and a cold water tank (usually stored in a loft) to work. Water passes from the cold tank to the immersion cylinder and the immersion cylinder heats and keeps water warm.

You program your immersion cylinder via the control panel to make sure that you have the hot water and central heating you need. However, if you forget to set your system and there's no water left in the immersion cylinder, it can take up to an hour before you'll have hot water again.

If your home has more than one bathroom or you have a large family and there's a high demand for hot water, a heat only boiler is often a more suitable option than a combi boiler. Although combis offer space-saving advantages, there is a maximum volume of water they can heat at any given time. This means that, if two or more people in your household want hot water at the same time, there will likely be a drop in temperature, volume and pressure to both points.

Is the Worcester Bosch Greenstar Danesmoor External 18/25 heat only boiler suitable for my house or apartment?

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

Output measures in kilowatts how much power a boiler can use when heating water for your radiators or taps. The higher the output rate, the more water it can heat.

If the output rate is too low, your hot water might often be only lukewarm, and if it is too high, you will be paying more for your oil than you need to.

The Worcester Bosch Greenstar Danesmoor External 18/25 heat only boiler has an output of 25 kW, so which types of property would it be most appropriate for?

Most experienced Gas Safe boiler installers would suggest that the Worcester Bosch Greenstar Danesmoor External 18/25 heat only boiler would be a suitable choice for installation in 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 boiler is 950 mm high, 565 mm wide, and 600 mm deep.

External, floor-standing heat only boilers like the Worcester Bosch Greenstar Danesmoor External 18/25 provide homeowners with more indoor space (they're installed outdoors) and reduce noise pollution (you can't really hear them from inside your house). They are also easier for engineers to work on if needed, while carbon monoxide leaks are less likely to pose a safety threat to your family because the gas disperses outside.

This model's weatherproof housing ensures protection from the British climate, reducing the likelihood of water ingress and rusting. And, since the oil is stored outdoors, there is minimal risk of leakage occurring inside your home that can cause significant damage as well as unpleasant odours which are hard to eliminate.

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

We always recommend to clients that they select the very latest condensing boiler for their home.

Condensing boilers like the Worcester Bosch Greenstar Danesmoor External 18/25 are more efficient with the oil they use in operation, meaning that you'll benefit from lower fuel bills. Condensing boilers are also better for the environment.

They achieve their efficiency by capturing and recycling the heat still present in the water vapour condensation and flue exhaust gases created when a boiler burns oil to get the energy it needs. It then reuses that recycled heat to perform a number of tasks, including heating the colder water that comes back to your boiler via the radiator.

What energy efficiency ratings have been awarded to the Worcester Bosch Greenstar Danesmoor External 18/25 heat only?

More and more homeowners are aware of the importance of how we heat our homes and its impact on climate change and other environmental issues.

The power we need for our central heating systems accounts for around 14% of the UK’s greenhouse gas production. There are often dangerous levels of ambient nitrogen dioxide gases in the atmospheres of British cities because of our use of gas boilers.

Would installing the Worcester Bosch Greenstar Danesmoor External 18/25 heat only in your home be an environmentally friendly decision? Let's look closely at the figures.

An energy efficiency rating of 92% or above is a legal requirement for all boilers manufactured and installed in the UK today. 92% is equivalent to a low-to-middle "A" grade on the "Seasonal Efficiency of Domestic Boilers" (SEDBUK) scale.

Energy efficiency measures how much energy a boiler uses and wastes in the course of its normal operation. The lower the waste, the lower your oil bills.

The Worcester Bosch Greenstar Danesmoor External 18/25 was awarded an efficiency rating of "90%", equivalent to a "A" rating on the SEDBUK system.

The ERP (Energy Related Products Directive) is European legislation that aims to reduce the use of energy at all points during a product's life, from the point of manufacture to when it's in active use right through to final disposal.

The regulation aims to encourage manufacturers to create products that are more environmentally friendly and which reduce gas emissions associated with those products.

The ERP grading for the Worcester Bosch Greenstar Danesmoor External 18/25 is "A".

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

The parts and labour warranty offered with this Worcester Bosch Greenstar Danesmoor External 18/25 heat only boiler covers you for 2 years.
