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?

If you are searching for a heat only boiler for your house or flat, the Worcester Bosch Greenstar Danesmoor External 18/25 is certainly one to consider.

If your home has more than one bathroom or you have a large family that uses a lot of hot water, a heat only boiler (sometimes called a standard boiler, a regular boiler or a conventional boiler) is likely to be the best option for you. Heat only boilers require both a hot water or immersion cylinder and a cold water tank. Once the water in the cylinder is heated, you can use this hot water throughout the day and it can feed multiple taps and showers at the same time.

This is in contrast to a combi boiler which can only heat a limited amount of water at any one time. This can cause a problem if two or more taps and showers are being used simultaneously as the water temperature, pressure and volume to all points will drop.

Heat only boilers allow you to program the times that you want heat and hot water to be available. However, if you forget to do this and the immersion cylinder is empty, you may have to wait up to an hour before hot water becomes available again.

If your property already has a water tank and cylinder, it will nearly always be cheaper to replace like for like instead of replacing it with a different type of boiler. In addition to new pipework, you may need to replace older radiators that may be unable to cope with the higher water pressure delivered by other types of boiler.

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

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.

The output of a boiler is measured in kilowatts and tells you how much power it has available to heat the water it sends to your hot taps, showers and radiators. The greater the demand for hot water in your home, the larger the output you will need.

It is important to select a boiler with the optimal output rate. Choose one with too high an output and your oil bills will be too expensive. Choose one with too low an output and sometimes the water in your radiators and coming out of your taps will be barely lukewarm.

The output of the Worcester Bosch Greenstar Danesmoor External 18/25 heat only is 25 kW kilowatts, so which types of property would this be most suitable for?

Most heating engineers would recommend this Worcester Bosch Greenstar Danesmoor External 18/25 heat only boiler as a suitable option for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


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

The Worcester Bosch Greenstar Danesmoor External 18/25 has the following dimensions - 950 mm high, 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 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 18/25 a condensing or non-condensing boiler?

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 oil for reuse.

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

Many homeowners are now worried about climate change and the damage they do to the environment from heating their homes has become a subject of increasing concern.

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?

The Worcester Bosch Greenstar Danesmoor External 18/25 is a heat only boiler you may wish to consider if you want this particular 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 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?

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 stands at 950 mm tall, 565 mm wide and 600 mm deep.

There are several benefits to choosing an external, floor-standing heat only boiler like the Worcester Bosch Greenstar Danesmoor External 18/25. External boilers free up space indoors and reduce internal noise pollution to almost zero. They are also easier for an engineer to access if a problem develops and an external boiler reduces the chances of carbon monoxide leaking into your property.

External boilers are fitted in weatherproof housing and are perfect for homes that require oil-fired heating because they are not connected to mains gas. Leakage is always a possibility with oil boilers but, as this Worcester Bosch Greenstar Danesmoor External 18/25 heat only boiler is fitted outside your home, there is likely to be much less damage to your property if it leaks and no odour of oil in your home.

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

The Worcester Bosch Greenstar Danesmoor External 18/25 is a condensing oil boiler - this is the type of boiler we recommend to most clients because they're better for the environment and they will save money on annual fuel bills.

A condensing boiler captures and recycles the warmth still present in both the flue exhaust gases and water vapour condensation created when oil is burned to provide your boiler with power.

This means it needs less oil to operate and it uses this extra energy to perform a number of tasks, including heating the colder water that comes back to the boiler from the radiators in your home.

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

How we heat our homes has become a major issue for many people worried about climate change and environmental issues in general.

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.

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 Danesmoor External 18/25 was awarded an efficiency rating of 90% with a SEDBUK band rating of "A".

The Energy Related Products (ERP) Directive is a European directive which applies to all products that consume energy over their lifetime.
