Worcester Bosch Greenstar Ri 27Ri heat only Gas boiler frequently asked questions

What type of boiler is Worcester Bosch’s Greenstar Ri 27Ri - system, regular or combi?

The Worcester Bosch Greenstar Ri 27Ri may be worth considering if you are looking for a heat only 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 standard boiler, a regular boiler or a conventional 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 water temperature, pressure and volume to all points will drop.

Heat only boilers allow you to program the times that you want 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 instead of replacing it with 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.

Would the Worcester Bosch Greenstar Ri 27Ri heat only boiler be suitable 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".

Output measures in kilowatts how much power a boiler can use when heating water for your radiators or taps. The higher the output rate, the more water it can heat.

If the output rate is too low, your hot water might often be only lukewarm, and if it is too high, you will be paying more for your gas than you need to.

The Worcester Bosch Greenstar Ri 27Ri heat only boiler has an output of 27 kW, so which types of property would it be most appropriate for?

An experienced Gas Safe engineer would say that this Worcester Bosch Greenstar Ri 27Ri heat only boiler's level of output makes it suitable for installing in larger properties including detached homes with 15 or more radiators and two or more bathrooms.


Worcester Bosch Greenstar Ri 27Ri size

The Worcester Bosch Greenstar Ri 27Ri is 600 mm tall, 390 mm wide, and 270 mm deep.

Is the Worcester Bosch Greenstar Ri 27Ri condensing or non-condensing?

Because of their increased energy efficiency, we recommend to all customers that they select one of the latest condensing boilers. Condensing boilers capture the heat from water vapour condensation and flue exhaust gases and recycle that heat to warm water entering the boiler (for example, from your radiators).

The Worcester Bosch Greenstar Ri 27Ri is a condensing gas boiler and choosing this model will result in a likely substantial reduction in your fuel bills, particularly if you're replacing an older, inefficient, non-condensing boiler.

Is the Worcester Bosch Greenstar Ri 27Ri heat only boiler environmentally friendly?

With more and more of us concerned about environmental issues and climate change, how we heat our homes has become an important issue to many homeowners.

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.

If you would like your next boiler to help in the fight against climate change, would the Worcester Bosch Greenstar Ri 27Ri heat only be a suitable choice?

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 Ri 27Ri was awarded an efficiency rating of 92%, equivalent to a SEDBUK grade of "A".

The Energy Related Products Directive grades products according to the energy they consume and the harmful gas emissions they create, from manufacturing right through to final disposal, including how they're used by customers between these two points.

The Worcester Bosch Greenstar Ri 27Ri is rated "A".

How many years' warranty does the Worcester Bosch Greenstar Ri 27Ri heat only come with?

The manufacturer offers a parts and labour warranty of 7 years on the Worcester Bosch Greenstar Ri 27Ri boiler to new customers.

Worcester Bosch Greenstar Ri 27Ri heat only Gas boiler frequently asked questions

Worcester Bosch Greenstar Ri 27Ri - combi, system or regular boiler?

The Worcester Bosch Greenstar Ri 27Ri may be worth considering if you are looking for a heat only boiler for your house or flat.

Sometimes called regular boilers, conventional boilers or standard boilers, heat only boilers require a cold water tank (often kept in the loft) and a hot water cylinder and an immersion heater (often kept in a landing or airing cupboard) to work. The immersion heater heats the water and keeps it warm.

With a heat only boiler, you pre-set a timer to tell the system when you want it to provide you with hot water and central heating. Remember though, if you don't program it and there's no water left in the hot water cylinder, you'll have to wait up to an hour before running a bath or shower.

Heat only boilers are better for larger homes or homes with more than one bathroom where there is a high demand for hot water at certain times of the day. Unlike with combi boilers where water pressure, volume and temperature drops if, for example, more than one person is using a hot tap, regular boilers can cope with multiple members of your household wanting hot water at the same time.

Is a Worcester Bosch Greenstar Ri 27Ri heat only boiler appropriate 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 27Ri heat only's output at 27 kW, which types of property would this Worcester Bosch Greenstar Ri 27Ri heat only boiler be most appropriate for?

Most experienced Gas Safe engineers would likely recommend that, at this level of output, this Worcester Bosch Greenstar Ri 27Ri heat only boiler would be a suitable choice for larger properties including detached homes with 15 or more radiators and two or more bathrooms.

Worcester Bosch’s Greenstar Ri 27Ri is 600 mm tall, 390 mm wide, and 270 mm deep.

Is the Worcester Bosch Greenstar Ri 27Ri a condensing or non-condensing boiler?

The Worcester Bosch Greenstar Ri 27Ri is a condensing boiler – we recommend to all clients that they choose the very latest condensing boilers because their efficiency continues to improve year after year.

Condensing boilers recycle heat from both water vapour condensation and flue exhaust gases via a secondary heat exchanger. With this heat, it performs other tasks like warming up colder water returning from your radiator without having to use more gas.

You will save money on your gas bills every year by choosing a condensing boiler as well as benefitting the environment.

How energy efficient is the Worcester Bosch Greenstar Ri 27Ri heat only boiler?

As more of us become concerned by the effects of climate change, the damage we do to the environment by heating our homes has emerged as an important issue for many homeowners.

Central heating systems are responsible for 14% of greenhouse gas emissions in the UK. You may also be aware that the gas boilers we use emit dangerous nitrogen dioxide in large volumes in the bigger British cities.

Will installing a Worcester Bosch Greenstar Ri 27Ri heat only be a positive contribution to the environment? Let's see what the experts say.

All boilers manufactured and installed in the UK are required to have an energy efficiency rating of 92% or above (or a good “A” SEDBUK rating). Before April 2018, when the law changed, the minimum energy efficiency level permissible was 88% (86-90% is a SEDBUK "B" rating and 90%+ is an "A" rating).

A boiler's energy efficiency rating indicates the amount of energy used and wasted during normal operational performance.

Following its assessment, the Worcester Bosch Greenstar Ri 27Ri 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 27Ri is "A".

How long is the warranty period on a Worcester Bosch Greenstar Ri 27Ri heat only boiler?
