Worcester Bosch Greenstar i System 24i System Gas boiler frequently asked questions

Worcester Bosch Greenstar I System 24i - a combi boiler, system boiler or regular boiler?

Worcester Bosch’s Greenstar I System 24i is one you might consider if you’re looking for a system boiler for your house or flat.

Like regular boilers, system boilers have a control panel that you use to program the times of the day when you want hot water to be available or the central heating to come on, such as in the morning when several people will be having showers or baths.

Once the water is heated, it is stored and kept warm in a hot water cylinder during the hours you've programmed. Hot water cylinders are often installed in an airing or landing cupboard and they contain built-in circulating pumps whose job is to heat water drawn from the mains.

System boilers do not need a cold-water tank like heat only boilers, making them a popular choice for homeowners who want to save space and those who are considering a loft conversion in the future. They're also easier for heating engineers to install, as they require one less large part. Instead, they use built-in circulating pumps.

Is the Worcester Bosch Greenstar I System 24i system suitable for my house or flat?

It's best to choose a boiler whose size or "output" is right for your property. With boilers, however, size does not mean how big a boiler is, it means how much power it has.

The output of a boiler is measured in kilowatts and tells you how much power it has available to heat the water it sends to your hot taps, showers and radiators. The greater the demand for hot water in your home, the larger the output you will need.

It is important to select a boiler with the optimal output rate. Choose one with too high an output and your gas bills will be too expensive. Choose one with too low an output and sometimes the water in your radiators and coming out of your taps will be barely lukewarm.

The output of the Worcester Bosch Greenstar I System 24i system is 24 kW kilowatts, so which types of property would this be most suitable for?

An experienced PlumbProud boiler engineer would recommend that this Worcester Bosch Greenstar i System 24i System boiler be installed in medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


What size is a Worcester Bosch Greenstar I System 24i boiler?

The Worcester Bosch Greenstar I System 24i is 710 mm tall, 400 mm wide, and 330 mm deep in size.

Is the Worcester Bosch Greenstar I System 24i condensing or non-condensing?

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

Condensing boilers like the Worcester Bosch Greenstar I System 24i 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 energy efficient is the Worcester Bosch Greenstar I System 24i system boiler?

The effects of climate change on the environment are leading many homeowners to question the damage they might be doing by the way they heat their homes.

As much as 14% of the UK’s greenhouse gas production derives from our domestic central heating systems. Gas boilers are responsible for dangerous levels of nitrogen dioxide emissions in Britain's largest cities.

Is the Worcester Bosch Greenstar I System 24i system an environmentally friendly choice for your home? Let’s have a look at the figures.

Boilers manufactured in the UK must be tested and, by law, achieve an energy efficiency rating of 92% or above, equivalent to a SEDBUK "A" grade. Most boilers achieve an "A" rating meaning they are at least 88% efficient.

The energy efficiency of a boiler indicates the amount of energy it uses (and wastes) during operation.

The Worcester Bosch Greenstar I System 24i has been assigned an efficiency rating of 94% with a SEDBUK rating 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 I System 24i is "A".

What is the warranty period on a Worcester Bosch Greenstar I System 24i system boiler?

A parts and labour warranty of 7 years is included when you purchase the Worcester Bosch Greenstar I System 24i boiler through PlumbProud.

Worcester Bosch Greenstar i System 24i System Gas boiler frequently asked questions

What type of boiler is the Worcester Bosch Greenstar I System 24i?

The Worcester Bosch Greenstar I System 24i boiler is a system boiler you may wish to consider when looking for a new boiler for your house or flat.

System boilers, like regular boilers, require a hot water cylinder (usually placed in a landing or airing cupboard) to work but they don’t require a separate cold water tank. This makes installation quicker and easier and, for homeowners with little loft space or who are considering a loft conversion, they're a more suitable choice.

System boilers don't need separate water tanks because they contain built-in circulating pumps that perform the same task. Just like heat only boilers, they require you to program in the times when you want heating and hot water to be available - they don't offer instant hot water like combi boilers. The cylinders keep whatever water they contain warm, although, if there is no hot water in the tank, you will have to wait up to an hour before hot water will come through your taps.

Is the Worcester Bosch Greenstar I System 24i system 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, 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 I System 24i system's output at 24 kW, which types of property would this Worcester Bosch Greenstar i System 24i System boiler be most appropriate for?

Most experienced Gas Safe boiler installers would recommend that a boiler with this output level would be most suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


What are the dimensions of the Worcester Bosch Greenstar I System 24i boiler?

The Worcester Bosch Greenstar I System 24i is 710 mm tall, 400 mm wide, and 330 mm deep in size.

Is the Worcester Bosch Greenstar I System 24i a non-condensing or condensing boiler?

Condensing gas boilers like the Worcester Bosch Greenstar I System 24i 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 gas to run.

Is the Worcester Bosch Greenstar I System 24i system considered environmentally friendly?

With so many of us worried about the environmental impact of our personal choices, the relationship between how we heat our homes and climate change has become an important issue for many homeowners.

Gas boilers are responsible for dangerous atmospheric levels of nitrogen dioxide emissions in Britain's biggest cities and, overall, 14% of the UK’s greenhouse gases are produced by our domestic central heating systems.

Would installing a Worcester Bosch Greenstar I System 24i system boiler in your home help combat climate change? What do the figures suggest?

The energy efficiency rating of the Worcester Bosch Greenstar I System 24i is 94% with a SEDBUK band rating of "A".

Energy efficiency tests record how much energy is wasted on non-core functions during an operation.

By law, all boilers manufactured and supplied in the UK must have a minimum energy efficiency performance level of 92% (equivalent to a SEDBUK "A" grade). Up to April 2018, the minimum performance level was 88% (88% and 89% are equivalent to a SEDBUK "B" grade and 90%+ an "A" grade).

The ERP (or Energy Related Products Directive) is a European regulation governing products which require energy to operate throughout their lives and encourages manufacturers to create products that are more environmentally friendly.

The legislation is designed to reduce the potential for harmful gas emissions during manufacturing and actual use right through to the point of final disposal.

For the Worcester Bosch Greenstar I System 24i, the ERP rating is "A".

What length of warranty does the Worcester Bosch Greenstar I System 24i come with?

The Worcester Bosch Greenstar I System 24i boiler is provided with a parts and labour warranty lasting 7 years.
