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

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

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

Heat only boilers are also referred to as regular boilers, conventional boilers or standard boilers. Heat only boilers require both a hot water/immersion cylinder (usually stored in a landing cupboard or airing cupboard) and a cold water tank (usually stored in a loft) to work. Water passes from the cold tank to the immersion cylinder and the immersion cylinder heats and keeps water warm.

You program your immersion cylinder via the control panel to make sure that you have the hot water and central heating you need. However, if you forget to set your system and there's no water left in the immersion cylinder, it can take up to an hour before you'll have hot water again.

If your home has more than one bathroom or you have a large family and there's a high demand for hot water, a heat only boiler is often a more suitable option than a combi boiler. Although combis offer space-saving advantages, there is a maximum volume of water they can heat at any given time. This means that, if two or more people in your household want hot water at the same time, there will likely be a drop in temperature, volume and pressure to both points.

Is the Worcester Bosch Greenstar Danesmoor Regular 18/25 heat only boiler the right choice for my house or apartment?

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 Regular 18/25 heat only boiler has an output rate of 25 kW, so which types of property would this be suitable for?

A heating engineer would recommend that this Worcester Bosch Greenstar Danesmoor Regular 18/25 heat only boiler would be a suitable installation choice for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


Dimensions of the Worcester Bosch Greenstar Danesmoor Regular 18/25 boiler

The Worcester Bosch Greenstar Danesmoor Regular 18/25 measures 855 mm tall, 370 mm wide, and 600 mm deep.

Many homeowners dislike the floor-standing boilers (like the Worcester Bosch Greenstar Danesmoor Regular 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.

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

We recommend that, if possible, you choose a condensing boiler like the Worcester Bosch Greenstar Danesmoor Regular 18/25.

Condensing boilers are more energy-efficient. They achieve this efficiency by capturing the heat present in flue exhaust gases and water vapour condensation and recycling that heat to, for example, warm colder water coming back from your radiators.

By choosing the latest condensing boiler, you'll also notice a significant reduction in your oil bills, particularly if you're replacing a boiler more than 15 years old.

What energy efficiency ratings have been awarded to the Worcester Bosch Greenstar Danesmoor Regular 18/25 heat only?

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.

Nitrogen dioxide emissions in Britain's largest cities are at dangerous levels and this has been caused by gas boilers. In fact, 14% of the UK’s greenhouse gases are produced by central heating.

Would choosing the Worcester Bosch Greenstar Danesmoor Regular 18/25 heat only help the environment? Let's see what the statistics suggest.

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 Regular 18/25 was awarded an efficiency rating of 90%, equivalent to a SEDBUK grade of "A".

Energy-efficient boilers help the environment as they require less fuel and emit fewer harmful gases. In 2015, the EU introduced the Energy Related Products Directive (ERP) with the aim of ensuring that all manufacturers, including boiler manufacturers, developed more efficient products and processes.

This legislation aims to conserve energy at all life cycle stages, from initial production through to actual use by a customer and up to the point of disposal.

The Worcester Bosch Greenstar Danesmoor Regular 18/25 has been given an ERP rating of "A".

Am I covered if the Worcester Bosch Greenstar Danesmoor Regular 18/25 heat only boiler breaks down?

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

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

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

The Worcester Bosch Greenstar Danesmoor Regular 18/25 may be worth considering if you are looking for a heat only boiler for your house or flat.

You may hear a heat only boiler being referred to as a conventional boiler, a standard boiler or a regular boiler, but they're all the same. Heat only boilers require both an immersion and a cold-water tank to function, the latter usually being situated in the loft. Water is kept warm throughout the day by the immersion cylinder for use when needed.

With a heat only boiler, you program the times at which you want to have hot water and central heating, but if you forget and there's no hot water left, you’ll have to wait for it to heat up before you have your bath or shower.

If you have a home with more than one bathroom, or a larger family, a heat only boiler will probably suit your needs. This is because, if you opted for a combi boiler instead, the water pressure, volume and temperature drop when more than one point is in use - for example if you have a shower while running hot water in the kitchen or another bathroom.

Is the Worcester Bosch Greenstar Danesmoor Regular 18/25 heat only boiler a suitable choice for my property?

To determine that, we need to consider the size of the boiler. Size doesn't mean how big the boiler is - it means how big its "output" is.

This Worcester Bosch Greenstar Danesmoor Regular 18/25 heat only boiler gets its power from oil and the power it's capable of producing is measured in kilowatts - the output rate is actually a kilowatt rate. The higher the output rate, the more kilowatts a boiler can use when heating water.

If you choose a boiler whose output rate is too low, it may not have enough power to make your water as hot as you would like. If you choose a boiler whose output rate is too high, you won't have to put up with lukewarm water but you will face higher oil bills.

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

An experienced heating engineer would recommend that the Worcester Bosch Greenstar Danesmoor Regular 18/25 heat only boiler is a suitable choice for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


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

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

Hundreds of thousands of properties in the UK still have floor-standing boilers like the Worcester Bosch Greenstar Danesmoor Regular 18/25 despite the fact that over the last 20 years more compact, wall-hung boilers have become the preference for most homeowners keen to free up space in their properties.

While it is possible to replace your existing floor-standing boiler with a wall-mounted boiler to free up space in your home, please bear in mind that much of the pipework might need replacing, which is over and above the cost of the boiler and its installation. This will be a significant one-off investment if you do decide to switch and while the savings on your oil bills will repay it eventually, this will take a few years.

Worcester Bosch Greenstar Danesmoor Regular 18/25 – condensing or non-condensing?

Condensing oil boilers like the Worcester Bosch Greenstar Danesmoor Regular 18/25 are environmentally friendlier and cheaper to run so, if possible, we strongly recommend that you choose this or one of the very latest models.

Condensing boilers are much more efficient and economical to run because they contain a secondary heat exchanger that captures and recycles the warmth still present in the flue exhaust gases and the water vapour condensation for re-use, meaning that they use less oil to run.

Is the Worcester Bosch Greenstar Danesmoor Regular 18/25 heat only boiler good for the environment?

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.

14% of the total amount of greenhouse gases produced by the UK comes from the central heating systems we use. In some of Britain's biggest cities, gas boilers create dangerous levels of nitrogen dioxide in the atmosphere.

Would installing the Worcester Bosch Greenstar Danesmoor Regular 18/25 heat only in your home be an environmentally friendly decision? Let's look closely at 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 Regular 18/25 was given an efficiency rating of 90% and a SEDBUK grading of "A".

The Energy Related Products Directive (ERP) intends to reduce the amount of energy consumed by individual products over their entire lifetime, from the initial manufacturing process to final disposal and at all points in between.

The legislation is designed to encourage manufacturers to create products that are more environmentally friendly and which result in a reduction in harmful gas emissions.

The ERP rating for the Worcester Bosch Greenstar Danesmoor Regular 18/25 is "A".

Does the Worcester Bosch Greenstar Danesmoor Regular 18/25 heat only boiler come with a warranty?

Worcester Bosch offers a parts and labour warranty of 2 years on the Worcester Bosch Greenstar Danesmoor Regular 18/25.
