Worcester Bosch Greenstar i System 30i System Gas boiler frequently asked questions

What type of boiler is the Worcester Bosch Greenstar I System 30i - regular, system or combi?

The Worcester Bosch Greenstar I System 30i boiler is an option you may wish to consider if you're looking for a system boiler for your house or flat.

System boilers need a hot water cylinder to work, with the most popular installation location for cylinders being in an airing or landing cupboard. Unlike heat only boilers though, they don't require a separate cold water tank to go in the attic, making them suitable if roof space is at a premium or if you're planning a loft conversion in the future.

System boilers use (often built-in) circulating pumps to distribute hot water to your taps and radiators. Fitting is cheaper and quicker too because you don't need to find room for a water tank. Unlike with a combi boiler, which heats water it draws from the mains instantly, you have to program a system boiler with the times you want hot water and heating.

Is the Worcester Bosch Greenstar I System 30i system boiler suitable for my house or apartment?

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.

A boiler’s output indicates the amount of power it can use when heating the water which it then sends to your taps and radiators. The higher the output rate, the more water it can heat.

If a boiler’s output is too low, there will be times when your hot water might not be as hot as you want it to be. If it is too high, you’ll likely be paying more than you need to for your gas.

Measured in kilowatts, the Worcester Bosch Greenstar I System 30i system's output level is 30 kW, so which types of property would this Worcester Bosch Greenstar i System 30i System boiler be an appropriate choice for?

A Gas Safe boiler installer would recommend that, at this level of output, the most suitable type of property for this Worcester Bosch Greenstar i System 30i System boiler would be larger properties including detached homes with 15 or more radiators and two or more bathrooms.


What size is the Worcester Bosch Greenstar I System 30i boiler?

The size of the Worcester Bosch Greenstar I System 30i boiler is 690 mm tall, 390 mm wide, and 280 mm deep.

Is the Worcester Bosch Greenstar I System 30i condensing or non-condensing?

The Worcester Bosch Greenstar I System 30i is a condensing gas boiler - we strongly suggest that you choose either this model or a recently released model if at all possible.

A condensing boiler captures and recycles the warmth present in flue exhaust gases and water vapour condensation created by the burning of gas to warm up the water coming back into your boiler - for example, from your radiators.

Condensing boilers cost less to run (lower gas bills) and are better for the environment.

Is the Worcester Bosch Greenstar I System 30i system boiler good for the environment?

How we heat our homes has become a major issue for many people worried about climate change and environmental issues in general.

Around 14% of the greenhouse gases produced in the UK is a result of our central heating systems. Gas boilers are responsible for dangerous levels of nitrogen dioxide emissions in some of our largest cities.

Would choosing a Worcester Bosch Greenstar I System 30i system help the environment? Let’s see what the performance figures suggest.

By law, the minimum level of energy efficiency for boilers manufactured in the UK is 92%, equivalent to a good SEDBUK “A” rating. Prior to April 2018, the minimum was 88% - boilers whose energy efficiency levels were 88% or 89% were given a "B" rating on the SEDBUK scale and those at 90% or higher were given an "A".

The energy efficiency rating awarded to each boiler indicates the amount of energy that is wasted when in operation.

Following testing, the Worcester Bosch Greenstar I System 30i was given a 92% energy efficiency rating and a SEDBUK grading of "A".

The Energy Related Products Directive intends to encourage all manufacturers to reduce harmful gas emissions connected to the products they make, from the manufacturing stage to final disposal, including when they are in active use.

The Worcester Bosch Greenstar I System 30i has an ERP rating of "A".

Does the Worcester Bosch Greenstar I System 30i system boiler come with a warranty?

The Worcester Bosch Greenstar I System 30i boiler offers a parts and labour warranty of 7 years.

Worcester Bosch Greenstar i System 30i System Gas boiler frequently asked questions

Is the Worcester Bosch Greenstar I System 30i a system, regular or combi boiler?

Worcester Bosch’s Greenstar I System 30i is one you might consider if you’re looking for a system boiler for your house or flat.

System boilers need a hot water cylinder to work, which is normally situated in an airing cupboard or similar. However, unlike heat only boilers, system boilers don’t require a separate cold water tank, meaning they are a preferred option for some homeowners, especially those planning a loft conversion in the future.

They use (often built-in) circulating pumps to distribute hot water to your taps and radiators and installation is often easier from scratch with heat only boilers as there’s one less component (the water tank) to purchase and fit.

System boilers also need programming for heat and hot water and don’t offer this instantly. However, the cylinder can keep water hot for use afterwards so you shouldn’t have to wait around for your bath water so long as you set your timer and have it on long enough to heat the water you’ll need for the day.

Is the Worcester Bosch Greenstar I System 30i system suitable for my house or flat?

Whether this Worcester Bosch Greenstar i System 30i System 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 I System 30i system is 30 kW, so which types of property would this model be appropriate for?

A PlumbProud heating engineer would recommend that this Worcester Bosch Greenstar i System 30i System boiler be installed in larger properties including detached homes with 15 or more radiators and two or more bathrooms.


What are the dimensions of the Worcester Bosch Greenstar I System 30i boiler?

The Worcester Bosch Greenstar I System 30i measures 690 mm in height by 390 mm in width by 280 mm in depth.

Is the Worcester Bosch Greenstar I System 30i non-condensing or condensing?

We recommend that, if possible, you select one of the very latest condensing gas boilers on the market like the Worcester Bosch Greenstar I System 30i.

Condensing boilers are better for the environment because they capture and recycle the heat still present in flue exhaust gases and water vapour condensation for re-use, meaning lower greenhouse gas emissions.

They're also a lot cheaper to run meaning that, if you're replacing a very old and inefficient boiler, the savings on your gas bill over 5-10 years add up to more than you pay for the boiler itself.

Is the Worcester Bosch Greenstar I System 30i system boiler rated as environmentally friendly?

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

In the UK, central heating systems account for 14% of greenhouse gas production. Gas boilers in particular are responsible for emissions of dangerous nitrogen dioxide in British cities.

Would installing the Worcester Bosch Greenstar I System 30i system in your home be an environmentally friendly decision? Let's look closely 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 I System 30i are 92% with a SEDBUK rating of "A".

The Energy Related Products (ERP) directive is Europe-wide legislation designed to reduce harmful gas emissions at all points of a product's life cycle - from the production process to its actual end use right through to final disposal.

The Worcester Bosch Greenstar I System 30i has a rating of "A".

Is this Worcester Bosch Greenstar I System 30i system covered by a warranty?

The Worcester Bosch Greenstar I System 30i is supplied with a parts and labour warranty of 7 years.
