Worcester Bosch Greenstar Ri 12Ri heat only Gas boiler frequently asked questions

Is the Worcester Bosch Greenstar Ri 12Ri boiler a combi, system or regular boiler?

If you want a heat only boiler for your flat or house, the Worcester Bosch Greenstar Ri 12Ri might be an option for you to consider.

Heat only boilers, also known as conventional boilers, standard boilers or regular boilers, require a hot water/immersion cylinder and a cold-water tank to work - the immersion cylinder is usually stored in a landing or airing cupboard and the cold water tank in your attic. Your water is kept hot throughout the day by the immersion cylinder.

You can schedule your hot water and heating at set times during the day, but if you forget to set your system and there's no hot water left, you'll have to wait for the immersion cylinder to heat your water for your bath or shower.

A heat only boiler is usually a better option if you have several bathrooms in your home or yours is a large household where there may be continual demand for hot water from different family members - combi boilers are not normally a suitable choice in these situations.

Should I install a Worcester Bosch Greenstar Ri 12Ri heat only boiler in my home?

You should make sure that the boiler you install in your property is the right "size". And, by size, we don't mean how big it is, we mean how powerful it is - the "output".

Your boiler has to be powerful enough to heat all the hot water you need for your radiators and taps. Power is measured in kilowatts and the more kilowatts a boiler has available to it, the more water it can heat.

If the output (measured in kilowatts) is too high, you'll have all the power you need and more but your gas bills will be much higher. If it's too low, you'll often find that the water coming out of your taps and fed into your radiators is only lukewarm.

With the Worcester Bosch Greenstar Ri 12Ri heat only's output at 12 kW, which types of property would this Worcester Bosch Greenstar Ri 12Ri heat only boiler be most appropriate for?

An experienced Gas Safe engineer would be likely to recommend that this Worcester Bosch Greenstar Ri 12Ri heat only boiler is capable of providing heating and hot water to up to 10 radiators and one bathroom and would therefore be most suitable for smaller homes and apartments.


What are the dimensions of the Worcester Bosch Greenstar Ri 12Ri boiler?

The Worcester Bosch Greenstar Ri 12Ri is 600 mm tall, 390 mm wide, and 270 mm deep.

Is this Worcester Bosch boiler non-condensing or condensing?

We always recommend to clients that they select the very latest condensing boiler for their home.

Condensing boilers like the Worcester Bosch Greenstar Ri 12Ri are more efficient with the gas 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 gas 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.

How does the Worcester Bosch Greenstar Ri 12Ri heat only rate environmentally?

How we heat our homes is an issue which many homeowners worry about as the world combats climate change and environmental damage.

In the largest cities of Britain, gas boilers are responsible for dangerous levels of atmospheric nitrogen dioxide emissions. In total, 14% of the UK’s greenhouse gases are produced by central heating systems.

Is the Worcester Bosch Greenstar Ri 12Ri heat only an environmentally friendly choice for your home? Let’s have a look 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 Ri 12Ri was awarded an efficiency rating of 92% 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.

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 Ri 12Ri has been awarded an ERP rating of "A".

How long is the warranty offered by the manufacturer for the Worcester Bosch Greenstar Ri 12Ri boiler?

The Worcester Bosch Greenstar Ri 12Ri boiler comes with a parts and labour warranty lasting 7 years.

Worcester Bosch Greenstar Ri 12Ri heat only Gas boiler frequently asked questions

What type of boiler is Worcester Bosch’s Greenstar Ri 12Ri - system, regular or combi?

The Worcester Bosch Greenstar Ri 12Ri is an option you may wish to consider if you’re looking for a heat only boiler for your house or flat.

Heat only boilers, sometimes known as standard boilers, regular boilers or conventional boilers, are better for homes with multiple bathrooms or larger families where members of your household may need to use hot water at the same time as each other, such as a shower in the bathroom and a hot water tap in the kitchen. This is because, unlike combi boilers, they can handle demand from more than one point at a time with no drop in water pressure, temperature and volume.

Heat only boilers use a hot water cylinder with an immersion heater (normally installed in an airing or landing cupboard) and a cold-water tank (normally stored in the loft).

You program a heat only boiler to provide you with the central heating and hot water you need at specific times of the day, such as first thing in the morning. However, if you forget to set timings and there is no water left in the hot water tank, you may have to wait up to an hour before you have hot water again.

Is the Worcester Bosch Greenstar Ri 12Ri heat only boiler a suitable option for my house or flat?

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 12Ri heat only boiler is 12 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.


What are the dimensions of the Worcester Bosch Greenstar Ri 12Ri boiler?

The Worcester Bosch Greenstar Ri 12Ri is 600 mm tall, 390 mm wide, and 270 mm deep in size.

Is this Worcester Bosch boiler non-condensing or condensing?

Condensing boilers convert the warmth present in flue exhaust gases and water vapour condensation into heat which they then recycle to increase the temperature of the colder water returning to your system.

We recommend that homeowners choose a condensing boiler like the Worcester Bosch Greenstar Ri 12Ri for this reason - the more recent your model the better because the technology improves every year.

You'll benefit from lower quarterly gas bills and condensing boilers are also much more environmentally friendly.

How energy efficient is the Worcester Bosch Greenstar Ri 12Ri heat only boiler?

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.

In Britain's bigger cities, gas boilers, in particular, are responsible for dangerous levels of nitrogen dioxide emissions. Overall, 14% of all of the UK’s greenhouse gas production comes from heating our homes.

Will choosing to install a Worcester Bosch Greenstar Ri 12Ri heat only in your home help the environment? Let's review the figures.

All boilers manufactured in the UK from April 2018 must achieve a SEDBUK “A” grade and an energy efficiency rating of 92% or above. Before that, the minimum was 88% - efficiency ratings of 88% and 89% were scored a “B” and 90%+ an "A".

A boiler's energy efficiency rating describes how much energy it uses and wastes during its standard operation.

The energy efficiency of the Worcester Bosch Greenstar Ri 12Ri was rated at 92% with a SEDBUK grading of "A".

The Energy Related Products Directive (ERP) came into force in 2015. This legislation was introduced to encourage manufacturers to create more energy-efficient products and it covers all products that consume energy during their lifetimes, including energy used during production and at the point of disposal.

The ERP assessors assigned a rating of "A" when testing the Worcester Bosch Greenstar Ri 12Ri.

How long is the warranty period on the Worcester Bosch Greenstar Ri 12Ri heat only boiler?

The manufacturer offers a parts and labour warranty of 7 years on the Worcester Bosch Greenstar Ri 12Ri boiler to new customers.
