Worcester Bosch Greenstar Ri 15Ri heat only Gas boiler frequently asked questions

Is the Worcester Bosch Greenstar Ri 15Ri boiler a combi, regular or a system boiler?

The Worcester Bosch Greenstar Ri 15Ri may be worth considering if you are looking for a heat only boiler for your house or flat.

Heat only boilers are sometimes called standard boilers, regular boilers or conventional boilers but they are actually the same thing. For a heat only boiler, you'll need to find space for both a cold-water tank and an immersion hot water cylinder - most households choose the attic for the former and a landing cupboard or airing cupboard for the latter. The immersion cylinder is the part of the system that keeps your hot water warm.

You program your boiler to provide you with the hot water you want at certain times, such as when you want to have a bath or a shower. However, if you don't remember to program your boiler, you'll have to wait for it to heat up if the hot water has run out.

A regular boiler is the most suitable choice if you have a larger family or if there is more than one bathroom in your home - the more popular combi boilers do not work well in homes where there is high and often simultaneous demand for hot water.

Is the Worcester Bosch Greenstar Ri 15Ri heat only 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 Ri 15Ri heat only's output at 15 kW, which types of property would this Worcester Bosch Greenstar Ri 15Ri heat only boiler be most 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.


What are the dimensions of the Worcester Bosch Greenstar Ri 15Ri boiler?

The measurements of the Worcester Bosch Greenstar Ri 15Ri are 600 mm by 390 mm by 270 mm.

Greenstar Ri 15Ri – non-condensing or condensing?

We recommend that, if possible, you choose a condensing boiler like the Worcester Bosch Greenstar Ri 15Ri.

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 gas bills, particularly if you're replacing a boiler more than 15 years old.

How environmentally friendly is the Worcester Bosch Greenstar Ri 15Ri heat only?

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

Do the figures suggest that installing the Worcester Bosch Greenstar Ri 15Ri heat only at your property would help in the fight against climate change?

All boilers manufactured and supplied in the UK must achieve an energy efficiency rating of at least 92% (an "A" SEDBUK grade). This is higher than the previous 88%, which was a legal requirement prior to April 2018.

The energy efficiency rating is used to work out how much energy a boiler both uses and wastes when it's switched on and working correctly - its standard functioning and operation.

The Worcester Bosch Greenstar Ri 15Ri is rated as 92% energy efficient, equivalent to a "A" SEDBUK rating.

The ERP (Energy Related Products Directive) applies to all products that consume energy at any time in their lifetime, from manufacture to disposal and all points in between.

The intention of this European legislation is to encourage manufacturers to offer end users products that are better for the environment through the creation of fewer harmful gas emissions at all points of a product's life cycle.

The ERP rating for the Worcester Bosch Greenstar Ri 15Ri is "A".

How long am I covered by the warranty for if the Worcester Bosch Greenstar Ri 15Ri breaks down?

The Worcester Bosch Greenstar Ri 15Ri boiler comes with a parts and labour warranty of 7 years.

Worcester Bosch Greenstar Ri 15Ri heat only Gas boiler frequently asked questions

What type of boiler is the Worcester Bosch Greenstar Ri 15Ri?

The Worcester Bosch Greenstar Ri 15Ri is a heat only boiler you may wish to consider if you want this type of boiler for your house or flat.

If your home has more than one bathroom or you have a large family that uses a lot of hot water, a heat only boiler (sometimes called a regular boiler, a conventional boiler or a standard boiler) is likely to be the best option for you. Heat only boilers require both a hot water or immersion cylinder and a cold water tank. Once the water in the cylinder is heated, you can use this hot water throughout the day and it can feed multiple taps and showers at the same time.

This is in contrast to a combi boiler which can only heat a limited amount of water at any one time. This can cause a problem if two or more taps and showers are being used simultaneously as the temperature, pressure and volume to all points will drop.

Heat only boilers allow you to program the times that you wish heat and hot water to be available. However, if you forget to do this and the immersion cylinder is empty, you may have to wait up to an hour before hot water becomes available again.

If your property already has a water tank and cylinder, it will nearly always be cheaper to replace like for like and not choose a different type of boiler. In addition to new pipework, you may need to replace older radiators that may be unable to cope with the higher water pressure delivered by other types of boiler.

Is the Worcester Bosch Greenstar Ri 15Ri heat only boiler a suitable choice for my property?

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 Ri 15Ri heat only boiler is 15 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.


Dimensions of the Worcester Bosch Greenstar Ri 15Ri boiler

The Worcester Bosch Greenstar Ri 15Ri is 600 mm tall, 390 mm wide, and 270 mm deep in size.

Is the Worcester Bosch Greenstar Ri 15Ri condensing or non-condensing?

This Worcester Bosch Greenstar Ri 15Ri is a condensing gas 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 gas bills as well as benefitting the wider environment.

Is the Worcester Bosch Greenstar Ri 15Ri heat only boiler an environmentally friendly choice?

As the British public has become more conscious of climate change, many homeowners consider the environment when choosing how to heat their homes.

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.

Would choosing the Worcester Bosch Greenstar Ri 15Ri heat only be an environmentally-friendly choice? If so, let's look at its performance 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 15Ri was given an efficiency rating of 92% and a SEDBUK grading 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 Ri 15Ri has been given an ERP rating of "A".

What warranty do I get if I purchase the Worcester Bosch Greenstar Ri 15Ri boiler?

The parts and labour warranty on the Worcester Bosch Greenstar Ri 15Ri lasts for 7 years.
