Worcester Bosch Greenstar Ri 18Ri heat only Gas boiler frequently asked questions

What type of boiler is Worcester Bosch’s Greenstar Ri 18Ri - system, regular or combi?

Looking for a gas heat only boiler for your house or flat? If you are, the Worcester Bosch Greenstar Ri 18Ri boiler may be worth considering.

Large family homes and properties with more than one bathroom benefit most from installing a heat only boiler (also referred to as a conventional boiler, a standard boiler or a regular boiler). Heat only boilers require both a cold water tank and hot water cylinder and an immersion heater. The immersion heater heats and keeps the water warm and feeds hot water to taps, radiators and other sources via the boiler.

Tell your boiler the times and days when you want hot water and central heating and it'll be there waiting for you. However, if you forget and there's no hot water left in your tank, you'll have to wait up to an hour before it's ready.

The biggest benefit of a heat only boiler is that, unlike a combi boiler, it’s possible to run two taps with hot water at the same time with no drop in pressure, volume or temperature (a known issue with combi boilers). It also means you can shower and have the dishwasher running at the same time without your water pressure being affected.

Is the Worcester Bosch Greenstar Ri 18Ri heat only boiler a suitable option 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 gas than you should be.

The Worcester Bosch Greenstar Ri 18Ri heat only boiler has an output rate of 18 kW, so which types of property would this be suitable for?

A PlumbProud boiler engineer would recommend that this Worcester Bosch Greenstar Ri 18Ri heat only boiler is suitable for smaller homes and apartments with up to 10 radiators and one bathroom.


The size of the Worcester Bosch Greenstar Ri 18Ri in millimetres

The Worcester Bosch Greenstar Ri 18Ri occupies a space of 600 mm high by 390 mm wide and 270 mm deep.

Is the Worcester Bosch Greenstar Ri 18Ri a non-condensing or condensing boiler?

We strongly recommend that you choose a condensing boiler like the Worcester Bosch Greenstar Ri 18Ri - the technology is improving every year so the newer the boiler, the better.

A condensing boiler captures and recycles the warmth still present in flue exhaust gases and water vapour condensation into heat, allowing it to perform more efficiently on tasks like heating the colder water returning from your radiators.

They also offer significant annual savings on household gas bills as well as being more environmentally friendly.

Is the Worcester Bosch Greenstar Ri 18Ri heat only rated as environmentally friendly?

Environmentally-friendly heating has become an important issue for homeowners concerned about the accelerating pace of 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.

Will you be helping the environment if you decide to install a Worcester Bosch Greenstar Ri 18Ri heat only in your home? Let’s look at the figures.

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 Ri 18Ri was given an efficiency rating of 92% and a SEDBUK grading of "A".

In 2015, new legislation was introduced by the EU to encourage manufacturers to develop more energy-efficient products that emit fewer harmful gases throughout their lifetime.

The Energy Related Products Directive (ERP) applies to all products that consume energy, including during the manufacturing process, at the point of final disposal, and all points in between.

The ERP rating of the Worcester Bosch Greenstar Ri 18Ri is "A".

Am I covered if the Worcester Bosch Greenstar Ri 18Ri heat only boiler breaks down?

Worcester Bosch offers a parts and labour warranty of 7 years on the Worcester Bosch Greenstar Ri 18Ri.

Worcester Bosch Greenstar Ri 18Ri heat only Gas boiler frequently asked questions

What type of boiler is Worcester Bosch’s Greenstar Ri 18Ri - system, regular or combi?

The Worcester Bosch Greenstar Ri 18Ri is an option you may wish to consider if you’re looking for a heat only boiler for your house or flat.

You can program a heat only boiler (sometimes called a standard boiler, a regular boiler or a conventional boiler) to provide hot water and heating at particular times of the day. Heat only boilers consist of a cold water tank (often housed out of sight in the loft), a hot water cylinder with an immersion heater (normally situated in an airing or landing cupboard), and a control panel.

Regular boilers are best suited for large households with many members, at least two of whom often need hot water at the same time.

Is the Worcester Bosch Greenstar Ri 18Ri heat only boiler a suitable option for my house or flat?

Whether this Worcester Bosch Greenstar Ri 18Ri heat only boiler is right for where you live depends on its size or what its "output" level is. Size does not mean its physical dimensions, however - it means how powerful it is.

The output of a boiler is measured in kilowatts and indicates how much energy it can use to heat the water needed for your radiators, taps and showers. The greater the output, the more water it can heat.

A boiler whose output is too high will give you hot water and warm radiators but also higher gas bills, whereas a boiler whose output is too low will result in cheaper gas bills but the water might not always be as hot as you want it to be.

The output of the Worcester Bosch Greenstar Ri 18Ri heat only is 18 kW, so which types of property would this model be appropriate for?

A PlumbProud boiler engineer would recommend that this Worcester Bosch Greenstar Ri 18Ri heat only 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 Ri 18Ri boiler?

The Worcester Bosch Greenstar Ri 18Ri is 600 mm tall, 390 mm wide, and 270 mm deep.

Is the Worcester Bosch Greenstar Ri 18Ri condensing or non-condensing?

The Worcester Bosch Greenstar Ri 18Ri is a condensing gas boiler - where possible, we always recommend to clients that they choose one of the very latest condensing boilers to take advantage of this technology, which improves year after year.

Condensing boilers are more energy-efficient as they capture and recycle the heat contained in flue exhaust gases and water vapour condensation. They then use this heat to perform tasks like warming up colder water returning to the boiler from the radiators.

By choosing a condensing boiler, you'll help the environment as well as save money on your gas bills.

Is the Worcester Bosch Greenstar Ri 18Ri heat only good for the environment?

How we heat our homes and the damage this does to the environment has become a pressing concern for many homeowners worried about the effects and impact of climate change.

The power we need for our central heating systems accounts for around 14% of the UK’s greenhouse gas production. There are often dangerous levels of ambient nitrogen dioxide gases in the atmospheres of British cities because of our use of gas boilers.

Is the Worcester Bosch Greenstar Ri 18Ri heat only an environmentally friendly choice for your home? Let’s have a look at the figures.

All boilers manufactured and supplied in the UK are assigned two energy efficiency ratings. By law, they must achieve a SEDBUK "A" rating subject to a minimum efficiency level of 92%. Prior to that, the minimum was 88% (88% and 89% are equivalent to a SEDBUK "B" grade and 90% and above an "A" grade).

The ratings awarded to the Worcester Bosch Greenstar Ri 18Ri are 92% with a SEDBUK rating of "A".

The Energy Related Products Directive, also known as ERP, is European legislation that intends to reduce energy consumption related to products right from their initial manufacturing process through to eventual final disposal.

The purpose of the directive is to encourage manufacturers to create new products that are kinder to the environment and which result in lower overall harmful gas emissions through a product's entire life cycle.

The Worcester Bosch Greenstar Ri 18Ri has a rating of "A".

What warranty does the Worcester Bosch Greenstar Ri 18Ri heat only boiler come with?
