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

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

If you are considering installing a system boiler in your house or flat, then the Worcester Bosch Greenstar Danesmoor System Utility 18/25 boiler is certainly worth investigating.

System boilers need a hot water cylinder to work, with the most popular installation location for cylinders being in an airing or landing cupboard. Unlike heat only boilers though, they don't require a separate cold water tank to go in the attic, making them suitable if roof space is at a premium or if you're planning a loft conversion in the future.

System boilers use (often built-in) circulating pumps to distribute hot water to your taps and radiators. Fitting is cheaper and quicker too because you don't need to find room for a water tank. Unlike with a combi boiler, which heats water it draws from the mains instantly, you have to program a system boiler with the times you want hot water and heating.

Is a Worcester Bosch Greenstar Danesmoor System Utility 18/25 system boiler suitable for my house or apartment?

It's best to choose a boiler whose size or "output" is right for your property. With a boiler, however, size does not mean how big the boiler is, it means how much power it has.

The amount of hot water you get from showers, bathrooms, and sinks and heat from your radiators depends on your boiler's output (measured in kilowatts). The higher the level of output, the better your home will be heated and you can be more certain that the water from your taps will be as hot as you want.

However, you must be careful. You might not get the hot water you want if your boiler output is too low. If it's too high, you'll be paying more than you need to for gas.

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

An experienced PlumbProud Gas Safe boiler installer would recommend that this Worcester Bosch Greenstar Danesmoor System Utility 18/25 System boiler is appropriate for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


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

The Worcester Bosch Greenstar Danesmoor System Utility 18/25 has the following dimensions - 855 mm high, 370 mm wide, and 600 mm deep.

Compact wall-mounted boilers have been the models of choice for most homeowners over the last 20 years. But many thousands of properties in the UK still have a floor-standing boiler like the Worcester Bosch Greenstar Danesmoor System Utility 18/25. If you're interested in switching to a wall-mounted unit to create extra space in your property, bear in mind that there might be a premium on the installation work because you may need to replace your current piping.

Newer compact boilers mean lower oil bills and you could recover the cost of your investment from those savings within a few years.

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

We recommend that you choose a condensing boiler wherever possible like the Worcester Bosch Greenstar Danesmoor System Utility 18/25 - try to go for the latest model, if possible, to take advantage of improving technology.

Condensing boilers capture and recycle the warmth still present in the water vapour condensation and in flue exhaust emissions created by burning oil to make them more efficient and economical to run.

You will save money on your oil bills too, plus condensing boilers are friendlier to the environment.

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

With more and more people concerned about climate change, how we heat our homes and the damage it does to the environment is increasingly being questioned by British homeowners.

Central heating accounts for 14% of greenhouse gas emissions in the UK. In larger British cities, gas boilers emit dangerous levels of nitrogen dioxide into the atmosphere.

Will choosing a Worcester Bosch Greenstar Danesmoor System Utility 18/25 system boiler for your home be positive for the environment? Let's examine the figures.

The energy efficiency rating of the Worcester Bosch Greenstar Danesmoor System Utility 18/25 is 90% with a SEDBUK band rating of "A".

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

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

When looking for a system boiler for your house or flat, the Worcester Bosch Greenstar Danesmoor System Utility 18/25 might be a suitable option for you.

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.

Would the Worcester Bosch Greenstar Danesmoor System Utility 18/25 system be a suitable boiler 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.

Your boiler's output indicates the maximum amount of power available to it to heat the water you need to warm your radiators or when you want hot water from your taps. A higher output rate means that your boiler is capable of heating greater volumes of water.

If a boiler's output rate is too low, you'll often find that the water is not as hot as you want it to be. Too high, however, and you'll end up paying more for your oil than you should be.

The Worcester Bosch Greenstar Danesmoor System Utility 18/25 system boiler has an output rate of 25 kW, so which types of property would this be suitable for?

Most experienced Gas Safe boiler installers would suggest that the Worcester Bosch Greenstar Danesmoor System Utility 18/25 system boiler would be a suitable choice for installation in medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


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

The Worcester Bosch Greenstar Danesmoor System Utility 18/25 boiler measures 855 mm [H] x 370 mm [W] x 600 mm [D] in size.

If you want to replace your floor-standing boiler with a more compact, wall-mounted model, this will give you and your family more space. Hundreds of thousands of homes in the UK still use floor-standing boilers like the Worcester Bosch Greenstar Danesmoor System Utility 18/25, but wall-mounted models have been the most popular choice for homeowners over the last two decades. We can replace your floor-mounted unit with a wall-mounted unit, but please be aware that the cost of installation will be higher if we need to replace your current piping.

However, you can recoup this investment in full over a few years with the savings you make on your oil bills.

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

This Worcester Bosch Greenstar Danesmoor System Utility 18/25 is a condensing oil boiler - we always recommend that clients choose the latest condensing models to benefit from the technology, which continues to improve year after year.

Condensing boilers capture the heat still present in flue exhaust gases and water vapour condensation, processing them through a secondary heat exchanger to, among other tasks, heat colder water returning from your radiators.

By selecting a modern condensing boiler, you'll save money on your oil bills as well as benefitting the wider environment.

Is the Worcester Bosch Greenstar Danesmoor System Utility 18/25 system environmentally friendly?

As more of us are increasingly concerned about climate change, how we heat our homes and its impact on the environment has become an issue of importance to homeowners.

Would choosing a Worcester Bosch Greenstar Danesmoor System Utility 18/25 system help in the fight against climate change? What do the performance statistics suggest?

In the UK, by law, all boilers manufactured since April 2018 must have a SEDBUK “A” rating and operate to a minimum level of 92% energy efficiency. Prior to this, the minimum was 88% – 88/89% would score a "B" and 90% or more an "A" on the SEDBUK scale.

The energy efficiency rating measures the amount of energy a boiler consumes when it's in use and how much it loses on non-core operations.

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

The Energy Related Products (ERP) Directive's aim is to reduce the harmful gas emissions created during a product’s manufacture and active end use right through to its disposal.
