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

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

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

A system boiler needs a hot water cylinder to work but it does not require a cold water tank, unlike with heat only boilers. This makes system boilers suitable for properties that lack loft space (or have no loft at all) or where a loft conversion is planned. The cylinder stores hot water for use throughout the day and water can be distributed to more than one tap or shower simultaneously without a loss of pressure or temperature (something combi boilers really struggle with).

System boilers are generally found in larger homes or properties housing large families. System boilers are easier to install than heat only boilers because their major components, including the circulation pump, are built-in and, of course, no cold water tank is needed.

With a system boiler, you use the control panel to set times for when you want the heating and hot water to be available but, unlike combi boilers, they cannot deliver hot water instantly. If you don't set your timer, you will have to wait for the water to heat up.

Should I install a Worcester Bosch Greenstar Danesmoor System 18/25 system boiler in my home?

You should make sure that the boiler you install in your property is the right "size". And, by size, we don't mean how big it is, we mean how powerful it is - the "output".

Your boiler has to be powerful enough to heat all the hot water you need for your radiators and taps. Power is measured in kilowatts and the more kilowatts a boiler has available to it, the more water it can heat.

If the output (measured in kilowatts) is too high, you'll have all the power you need and more but your oil bills will be much higher. If it's too low, you'll often find that the water coming out of your taps and fed into your radiators is only lukewarm.

With the Worcester Bosch Greenstar Danesmoor System 18/25 system's output at 25 kW, which types of property would this Worcester Bosch Greenstar Danesmoor System 18/25 System boiler be most appropriate for?

An experienced Gas Safe boiler installer would recommend that the Worcester Bosch Greenstar Danesmoor System 18/25 system boiler would be an ideal installation 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 is 855 mm tall, 370 mm wide, and 600 mm deep in size.

Many homeowners dislike the floor-standing boilers (like the Worcester Bosch Greenstar Danesmoor System 18/25) they have in their properties because they feel that they are bulky and take up too much room. If this is you and you want to replace what you have now with a compact, wall-mounted boiler, we can do this for you, although please note that you may need to pay for new piping.

The oil bill savings offered by modern boilers are significant, however, and you should be able to recoup your investment in a few years.

Greenstar Danesmoor System 18/25 – non-condensing or condensing?

Condensing boilers like the Worcester Bosch Greenstar Danesmoor System 18/25 improve energy efficiency and reduce your annual expenditure on oil.

They do this by capturing and recycling the warmth still present in water vapour condensation and flue exhaust gases to, for example, increase the temperature of the colder water returning from your radiators.

Condensing boilers are also much better for the environment because they emit fewer greenhouse gases.

How does the Worcester Bosch Greenstar Danesmoor System 18/25 system rate environmentally?

With environmental issues in the spotlight, more and more homeowners are becoming concerned about how they heat their homes and how much they're contributing towards combatting 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 choosing to install a Worcester Bosch Greenstar Danesmoor System 18/25 system in your home help the environment? Let's review the figures.

All new British boilers must perform to a legal minimum energy efficiency of 92% (a low to good SEDBUK "A" rating). Prior to April 2018, the target was 88% (86-90% = SEDBUK "B" and 90%+ = SEDBUK "A").

Efficiency ratings are intended to let consumers know how much energy a boiler uses in its day-to-day activities and how much energy goes to waste.

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

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 System 18/25 is "A".

What warranty does the Worcester Bosch Greenstar Danesmoor System 18/25 system boiler come with?

The Worcester Bosch Greenstar Danesmoor System 18/25 boiler comes with a parts and labour warranty of 2 years.

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

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

Suitable for a house or a flat, the Worcester Bosch Greenstar Danesmoor System 18/25 system boiler is worth considering if you want a system boiler.

System boilers require a hot water cylinder to work (normally stored in an airing or landing cupboard) but, unlike heat only boilers, they do not require a cold water tank. This makes them more suitable for homes that do not have lofts, where attic space is limited or where a loft conversion is being considered.

You program your heating and hot water to come on via the control panel. But if you forget to set the timer, you will have to wait a while for the water to heat up. Hot water is stored in the cylinder for use throughout the day and can be distributed to multiple showers and taps at the same time without a loss of pressure or temperature (something combi boilers really struggle with). For this reason, a system boiler is a suitable option for large families and homes with more than one bathroom.

As no cold-water tank is needed with a system boiler and many major system components are built into it, this type of boiler can be easier to install than a standard boiler.

Is a Worcester Bosch Greenstar Danesmoor System 18/25 system a suitable choice 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 System 18/25 system's output level is 25 kW, so which types of property would this Worcester Bosch Greenstar Danesmoor System 18/25 System boiler be an appropriate choice for?

A Gas Safe boiler installer would say that this Worcester Bosch Greenstar Danesmoor System 18/25 System boiler's level of output makes it suitable for installing in medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


How large is a Worcester Bosch Greenstar Danesmoor System 18/25 boiler?

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

Because of their convenient and compact size, wall-hung boilers have become the popular choice for homeowners over the last 20 years. Yet while hundreds of thousands of UK properties still use floor-standing boilers like the Worcester Bosch Greenstar Danesmoor System 18/25, many consider switching to wall-mounted units to create extra living space.

We can replace your floor-standing boiler if you wish but there may be an additional cost if we have to replace much of your existing pipework. The savings you make on your oil bills every quarter should repay that investment within a few years.

Greenstar Danesmoor System 18/25 – non-condensing or condensing?

The Worcester Bosch Greenstar Danesmoor System 18/25 is a condensing oil boiler - we’d strongly recommend that you choose the very latest condensing model for your home.

Condensing boilers run on either gas or oil and are manufactured specifically to improve energy efficiency. They do this by capturing and recycling the warmth present in flue exhaust gases and water vapour condensation into more usable heat the system can use, meaning they're far more efficient and cost less to run.

How does the Worcester Bosch Greenstar Danesmoor System 18/25 system rate environmentally?

As more of us become concerned by the effects of climate change, the damage we do to the environment by heating our homes has emerged as an important issue for many homeowners.

In the largest cities of Britain, gas boilers are responsible for dangerous levels of atmospheric nitrogen dioxide emissions. In total, 14% of the UK’s greenhouse gases are produced by central heating systems.

Would installing a Worcester Bosch Greenstar Danesmoor System 18/25 system boiler in your home be a green choice? Let's look at the numbers.

By law, boilers manufactured and supplied in the UK must achieve a SEDBUK rating of "A" and work at a 92% minimum efficiency. Before April 2018, a minimum of 88% energy efficiency needed to be achieved (88/89% = SEDBUK "B" and 90% = SEDBUK "A").

Following official testing, the Worcester Bosch Greenstar Danesmoor System 18/25 was given an efficiency rating of 90% with a SEDBUK rating of "A".

Energy efficiency is a measure of how much energy is used and how much is wasted when a boiler is operating.

The Energy Related Products (ERP) directive is Europe-wide legislation designed to reduce harmful gas emissions at all points of a product's life cycle - from the production process to its actual end use right through to final disposal.

The Worcester Bosch Greenstar Danesmoor System 18/25 has a rating of "A".

What is the warranty period on a Worcester Bosch Greenstar Danesmoor System 18/25 system boiler?

The parts and labour warranty on the Worcester Bosch Greenstar Danesmoor System 18/25 covers all repair-related costs for 2 years while the heat exchange warranty covers you for [Heat Exchange Warranty] years.
