Worcester Bosch Greenstar Danesmoor External System 12/18 System Oil boiler frequently asked questions

Worcester Bosch Greenstar Danesmoor External System 12/18 - a system boiler, regular boiler or combi boiler?

Suitable for a house or a flat, the Worcester Bosch Greenstar Danesmoor External System 12/18 system boiler is worth considering if you want a system boiler.

Like heat only boilers, system boilers require a hot water cylinder to work - the cylinder stores and keeps water warm for use throughout the day. Hot water can be distributed to multiple showers and taps simultaneously, making system boilers suitable for larger families and properties with more than one bathroom.

System boilers differ from standard boilers in that they do not require a cold water tank, making them suitable for properties with no loft space or if you are planning a loft conversion. As the boiler's major components, including the circulation pump, are built-in and no water tank is required, system boilers are easier to install than regular boilers.

This type of boiler does not heat water instantly like a combi boiler - instead, you need to use the control panel to set the times when you want heating and hot water to be available for your home.

Is the Worcester Bosch Greenstar Danesmoor External System 12/18 system 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".

Your boiler should be able to cope with peak hot water demand in your property and not just your average hot water usage. The output rate of a boiler is measured in kilowatts and tells you how much power a boiler can use to provide hot water to your taps, showers and radiators.

If the output of your boiler is too low, there will often be times when your water isn't as hot as you want. But if your boiler output is too high, it will be more costly to run (often unnecessarily).

The output of the Worcester Bosch Greenstar Danesmoor External System 12/18 system boiler is 18 kW kilowatts. Which types of property would this be appropriate for?

Most boiler engineers would recommend that a boiler with this output level would be most suitable for smaller homes and apartments with up to 10 radiators and one bathroom.


Where will the Worcester Bosch Greenstar Danesmoor External System 12/18 fit in my house?

The Worcester Bosch Greenstar Danesmoor External System 12/18 occupies a space of 950 mm high by 565 mm wide and 780 mm deep.

External, floor-standing system boilers like the Worcester Bosch Greenstar Danesmoor External System 12/18 feature weatherproof housing - this means they can be installed outdoors to free up valuable space in your home. An external boiler also minimises indoor noise pollution and reduces the risk of carbon monoxide leaching into your property.

Oil boilers can and do leak. However, when a boiler is fitted externally, any leakage is less likely to damage your property and won't leave an unpleasant odour that is hard to remove. It is also worth remembering that an external boiler will be easier for an engineer to access if a problem develops.

Is the Worcester Bosch Greenstar Danesmoor External System 12/18 condensing or non-condensing?

We recommend the Worcester Bosch Greenstar Danesmoor External System 12/18 as it is a modern condensing oil boiler from a trusted manufacturer with a reputation for supplying highly energy-efficient boilers.

Condensing boilers capture the heat still present in water vapour condensation and flue exhaust gases and recycle it back into the heating system. With this extra energy, your boiler can, among other tasks, reheat colder water coming back from your radiators without having to burn more oil.

Condensing boilers significantly reduce your quarterly oil costs and they're better for the environment.

Is the Worcester Bosch Greenstar Danesmoor External System 12/18 system rated as environmentally friendly?

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.

Central heating produces 14% of all greenhouse gas emissions in the UK. Gas boilers in the larger cities emit dangerous levels of nitrogen dioxide.

Would installing the Worcester Bosch Greenstar Danesmoor External System 12/18 system in your home be an environmentally friendly decision? Let's look closely at the figures.

Every boiler manufactured and supplied in the UK must have an energy efficiency rating of 92% (SEDBUK “A” rating). These minimums were made law in April 2018 - before that, the minimum energy efficiency rating was 88% (88%/89% = "B" SEDBUK grade, 90%+ = "A" SEDBUK grade).

The Worcester Bosch Greenstar Danesmoor External System 12/18 was awarded an efficiency rating of 90% and a band rating of "A".

Energy efficiency ratings for boilers describe the amount of energy they use and waste when switched on and working.

All products that consume energy throughout their lifespan must comply with the Energy Related Products (ERP) Directive.

Companies are legally obliged to reduce harmful gas emissions at all stages of a product's life cycle, from initial manufacturing right through to final disposal as well as when the product is in actual use.

The Worcester Bosch Greenstar Danesmoor External System 12/18 scores "A".

If the Worcester Bosch Greenstar Danesmoor External System 12/18 system boiler breaks down, am I covered?

The Worcester Bosch Greenstar Danesmoor External System 12/18 boiler is provided with a parts and labour warranty lasting 2 years.

Worcester Bosch Greenstar Danesmoor External System 12/18 System Oil boiler frequently asked questions

Is the Worcester Bosch Greenstar Danesmoor External System 12/18 boiler a combi, regular or a system boiler?

If you want a system boiler for your flat or house, the Worcester Bosch Greenstar Danesmoor External System 12/18 might be an option for you to consider.

For homes that have a higher-than-average demand for hot water and heating and for larger properties, system boilers are a more suitable option than the more popular combi boilers.

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.

And, unlike heat only boilers that also require a cold water storage tank to work (normally fitted in the loft), system boilers don't, meaning they're quicker, easier and cheaper to install.

Is a Worcester Bosch Greenstar Danesmoor External System 12/18 system boiler suitable for my apartment or house?

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 System 12/18 system boiler has an output of 18 kW, so which types of property would it be most appropriate for?

A PlumbProud boiler engineer would recommend that this Worcester Bosch Greenstar Danesmoor External System 12/18 System boiler is suitable for smaller homes and apartments with up to 10 radiators and one bathroom.


What are the dimensions of the Worcester Bosch Greenstar Danesmoor External System 12/18 boiler?

Worcester Bosch’s Greenstar Danesmoor External System 12/18 is 950 mm tall, 565 mm wide, and 780 mm deep.

External, floor-standing system boilers like the Worcester Bosch Greenstar Danesmoor External System 12/18 don't require you to find space in your home for them and, because they're outside, you'll never hear them working unless you're out in the garden.

They provide much easier access for a heating engineer in case of a fault and their sturdy waterproof covering can handle the British climate as well as prevent rusting and water ingress.

Other benefits include the fact that gas will disperse into the atmosphere outdoors in the event of a carbon monoxide leak. The chances of an oil leak damaging your property are also greatly reduced because the boiler is not installed inside your property.

Is the Worcester Bosch Greenstar Danesmoor External System 12/18 condensing or non-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 System 12/18 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.

Is the Worcester Bosch Greenstar Danesmoor External System 12/18 system considered environmentally friendly?

How we heat our homes and the damage we might be doing to the environment as a result has become an important point of concern to many homeowners worried about climate change.

The heating of our homes accounts for 14% of the UK's greenhouse gas emissions. Especially in the big cities, gas boilers are responsible for dangerous levels of nitrogen dioxide emissions.

Will installing a Worcester Bosch Greenstar Danesmoor External System 12/18 system in your home be a positive contribution to the environment? The figures below will tell you more.

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 System 12/18 was awarded an efficiency rating of "90%", equivalent to a "A" rating on the SEDBUK system.

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 System 12/18 has been awarded an ERP rating of "A".

What length of warranty does the Worcester Bosch Greenstar Danesmoor External System 12/18 come with?

The Worcester Bosch Greenstar Danesmoor External System 12/18 boiler is provided with a parts and labour warranty lasting 2 years.
