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

Worcester Bosch Greenstar Danesmoor Utility 18/25 - a combi boiler, system boiler or regular boiler?

The Worcester Bosch Greenstar Danesmoor Utility 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.

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 Utility 18/25 heat only boiler suitable for my house or apartment?

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 Utility 18/25 heat only is 25 kW kilowatts, so which types of property would this be appropriate for?

To most boiler engineers, the Worcester Bosch Greenstar Danesmoor Utility 18/25 heat only Greenstar Danesmoor Utility would be most suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


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

The Worcester Bosch Greenstar Danesmoor Utility 18/25 measures 855 mm in height and has a width of 370 mm and a depth of 600 mm.

Wall-hung boilers have been the most popular installation choice over the last 20 years because they're compact, discreet, and don’t take up much space. Yet there are still hundreds of thousands of UK homeowners whose central heating is provided by floor-standing boilers like the Worcester Bosch Greenstar Danesmoor Utility 18/25, which they're looking to replace to free up more living space. This is possible, however please be aware that there may be an additional cost if we need to replace your existing pipework.

That said, you should be able to fully recoup your investment within a few years thanks to the quarterly savings you'll make on your oil bills.

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

The Worcester Bosch Greenstar Danesmoor Utility 18/25 is a condensing oil 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 oil to warm up the water coming back into your boiler - for example, from your radiators.

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

Does the Worcester Bosch Greenstar Danesmoor Utility 18/25 heat only protect the environment?

Many homeowners are becoming increasingly concerned about how they heat their homes and the impact it has on climate change and other important environmental issues.

Approximately 14% of the UK's greenhouse gas production is caused by our central heating systems. The gas boilers in larger urban areas of Britain are mainly responsible for emissions of toxic nitrogen dioxide.

Will installing a Worcester Bosch Greenstar Danesmoor Utility 18/25 heat only in your home be a positive contribution to the environment? The figures below will tell you more.

Boilers manufactured after April 2018 in the UK must achieve an "A" on the SEDBUK grading system as well as score a minimum of 92% on a separate energy efficiency test. Prior to that, the minimum was 88% - boilers rated at 88% and 89% were given a “B” rating (90% and higher were given an "A").

An energy efficiency rating describes how much energy the boiler uses and how much it wastes when in use.

The Worcester Bosch Greenstar Danesmoor Utility 18/25 was awarded an efficiency rating of 90% with a SEDBUK grading 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 Danesmoor Utility 18/25, the ERP rating is "A".

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

Worcester Bosch Greenstar Danesmoor Utility 18/25 - a system boiler, regular boiler or combi boiler?

The Worcester Bosch Greenstar Danesmoor Utility 18/25 boiler is a heat only boiler you may wish to consider when looking for a new boiler for your house or flat.

Heat only boilers (sometimes called conventional boilers, standard boilers or regular boilers) need both a hot water cylinder with an immersion heater and a cold-water tank to work. The cold water tank (normally found in an attic or a loft) passes water when required to the hot water cylinder (normally found in a landing or airing cupboard), which heats the water and keeps it warm.

When you set the times you want for your hot water and central heating, the hot water for your taps, showers, baths and radiators is drawn from the hot water cylinder. Bear in mind though that, if you forget to program the system and the hot water cylinder is empty, you may have to wait up to an hour for your hot water.

A heat only boiler is usually the recommended option for families or properties with multiple bathrooms. This is because, unlike combi boilers which can only effectively provide for one outlet at a time without a drop in water pressure, volume or temperature, standard boilers can handle demand from multiple points around the home at once.

Is the Worcester Bosch Greenstar Danesmoor Utility 18/25 heat only suitable 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.

A boiler’s output indicates the amount of power it can use when heating the water which it then sends to your taps and radiators. The higher the output rate, the more water it can heat.

If a boiler’s output is too low, there will be times when your hot water might not be as hot as you want it to be. If it is too high, you’ll likely be paying more than you need to for your gas.

Measured in kilowatts, the Worcester Bosch Greenstar Danesmoor Utility 18/25 heat only's output level is 25 kW, so which types of property would this Worcester Bosch Greenstar Danesmoor Utility 18/25 heat only boiler be an appropriate choice for?

Most experienced heating engineers would suggest that the most suitable type of property for installing a Worcester Bosch Greenstar Danesmoor Utility 18/25 heat only boiler in would be medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


What is the size of the Worcester Bosch Greenstar Danesmoor Utility 18/25?

The dimensions of the Worcester Bosch Greenstar Danesmoor Utility 18/25 are 855 mm [H] x 370 mm [W] x 600 mm [D].

Wall-hung boilers have become the preferred choice for homeowners in the UK over the last 20 years, but hundreds of thousands of homes still use bulkier floor-standing models for their central heating. It is possible to replace your floor-standing boiler with a wall-mounted one if you wish so that you and your family have more living space. But we must advise you that you may also have to pay to replace some or all of your existing pipework.

You should however be able to recoup this cost in full after a few years because of the savings you make each quarter on your oil bills.

Is the Worcester Bosch Greenstar Danesmoor Utility 18/25 a non-condensing or condensing boiler?

Condensing oil boilers like the Worcester Bosch Greenstar Danesmoor Utility 18/25 are more energy-efficient and choosing one for your home will cut the amount you pay every year for your oil.

They do this by capturing the heat in water vapour condensation and in exhaust gases which would normally be expelled via the flue. They then recycle that heat, returning it to the system to, among other tasks, reheat colder water that is returning to your boiler from your radiators.

How energy efficient is the Worcester Bosch Greenstar Danesmoor Utility 18/25 heat only boiler?

How we heat our homes and the effect that has on climate change has become important to many homeowners worried about the environment.

Would the environmental impact of installing a Worcester Bosch Greenstar Danesmoor Utility 18/25 heat only in your home be positive? Let's look at the numbers.

All boilers manufactured and installed in the UK are required by law to have an energy efficiency rating of at least 92%, equivalent to a good “A” rating on the SEDBUK scale. Before this, the minimum was 88% (ratings of 88% and 89% are equivalent to a high “B” SEDBUK rating and anything 90% or higher is an "A" rating).

A boiler's energy efficiency rating is designed to let you know how much energy is used and wasted during normal functioning.

The Worcester Bosch Greenstar Danesmoor Utility 18/25 was given an efficiency rating of 90% and a band rating of "A".

The ERP (or Energy Related Products Directive) is European legislation which applies to all products that consume energy throughout their lifetime.
