Worcester Bosch Greenstar Danesmoor System 18/25 System Oil boiler frequently asked questions

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

Looking for a oil system boiler for your house or flat? If you are, the Worcester Bosch Greenstar Danesmoor System 18/25 boiler may be worth considering.

Like regular boilers, system boilers have a control panel that you use to program the times of the day when you want hot water to be available or the central heating to come on, such as in the morning when several people will be having showers or baths.

Once the water is heated, it is stored and kept warm in a hot water cylinder during the hours you've programmed. Hot water cylinders are often installed in an airing or landing cupboard and they contain built-in circulating pumps whose job is to heat water drawn from the mains.

System boilers do not need a cold-water tank like heat only boilers, making them a popular choice for homeowners who want to save space and those who are considering a loft conversion in the future. They're also easier for heating engineers to install, as they require one less large part. Instead, they use built-in circulating pumps.

Would the Worcester Bosch Greenstar Danesmoor System 18/25 system boiler be suitable for my house or flat?

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

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

While a large number of properties in the UK still feature floor-standing boilers like the Worcester Bosch Greenstar Danesmoor System 18/25, the more compact wall-hung models are now the preferred options for most homeowners keen for more living space for themselves and their families. It is possible to replace your floor-standing unit with a wall-hung and more compact boiler but please note that much of the pipework could need replacing, making the overall cost of installation higher.

Your new compact will save you money on your oil bills every quarter, however, and those savings should cover the costs within a few years.

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

The Worcester Bosch Greenstar Danesmoor System 18/25 is a condensing boiler – we recommend to all clients that they choose the very latest condensing boilers because their efficiency continues to improve year after year.

Condensing boilers recycle heat from both water vapour condensation and flue exhaust gases via a secondary heat exchanger. With this heat, it performs other tasks like warming up colder water returning from your radiator without having to use more oil.

You will save money on your oil bills every year by choosing a condensing boiler as well as benefitting the environment.

Is the Worcester Bosch Greenstar Danesmoor System 18/25 system good for the environment?

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.

About 14% of the greenhouse gases we produce in the UK come from the power needed for central heating. In bigger British cities, gas boilers are a significant source of nitrogen dioxide emissions.

Will choosing to install a Worcester Bosch Greenstar Danesmoor System 18/25 system in your home help the environment? Let's review the figures.

All boilers manufactured in the UK from April 2018 must operate at a minimum level of energy efficiency of 92% ("A" rating on the SEDBUK scale). Before that, the minimum was 88% - boilers scoring 88/89% were given a SEDBUK "B" rating and 90% or above an "A" rating.

The energy efficiency score of a boiler indicates how much energy it uses and how much goes to waste when in use.

After its assessment, the Worcester Bosch Greenstar Danesmoor System 18/25 was given an efficiency rating of 90% and a SEDBUK grading 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 System 18/25 has a rating of "A" .

Worcester Bosch Greenstar Danesmoor System 18/25 System Oil boiler frequently asked questions

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

If you’re looking for a system boiler for your house or flat, you may wish to the consider the Worcester Bosch Greenstar Danesmoor System 18/25.

System boilers are suitable for homes with a higher-than-average demand for central heating and water - for example, larger homes and larger families.

Combi boilers heat water on demand but the amount of water they can actually deliver to taps is determined by the mains water pressure, flow rate and power. System boilers instead use a hot water cylinder that stores and keeps water hot throughout the day. As long as you remember to program the times you want hot water and the cylinder still has water left in it, you should have hot water whenever you need it.

System boilers do not require a cold water storage tank either, unlike heat only boilers, meaning they're cheaper, quicker and easier to install.

Is the Worcester Bosch Greenstar Danesmoor System 18/25 system 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 - its "output".

The output rate tells you how much energy your boiler has to use to provide you and your family with hot water and central heating. A higher output rate means that it can heat greater volumes of water.

Please be aware, though - if you choose a boiler whose output is too low, the water in your radiators and coming from your taps may not be warm enough. Conversely, if you choose a boiler with too high an output, you'll pay more for oil than is necessary.

The Worcester Bosch Greenstar Danesmoor System 18/25 system boiler has an output level of 25 kW, so which types of property would it be appropriate for?

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


The size of the Worcester Bosch Greenstar Danesmoor System 18/25 in millimetres

The Worcester Bosch Greenstar Danesmoor System 18/25 boiler is 855 mm high, 370 mm wide, and 600 mm deep.

Over the last 20 years, compact wall-hung boilers have been installed in far greater numbers in UK properties than floor-standing boilers like the Worcester Bosch Greenstar Danesmoor System 18/25. While hundreds of thousands of properties still have floor-standing boilers, many homeowners consider making the switch to wall-hung boilers to increase the amount of living space that they and their families can enjoy. We can swap your old floor-standing boiler for a wall-mounted boiler but please bear in mind that there may be an additional cost for your installation if we have to replace the pipework.

You should though be able to recoup this investment in full in just a few years with the savings you make on your oil bills.
