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

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

The Worcester Bosch Greenstar I 30i boiler is a combi boiler you may wish to consider when looking for a new boiler for your house or flat.

A combi boiler could be a better choice than a standard boiler if space is at a premium in your home. Combi boilers draw water directly from the mains supply and heat it instantly, removing the need for a hot water cylinder and a cold water tank.

Water is heated on demand and then distributed directly to your taps and showers. This means that combi boilers use less fuel and so reduce your gas bills.

The main disadvantage to combi boilers is that they can only heat a limited volume of water at any given time. If more than one tap or shower is in use, the hot water supply to both could be restricted and both the water pressure and temperature will drop.

Is a Worcester Bosch Greenstar I 30i combi boiler suitable for my apartment or house?

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 I 30i combi boiler has an output of 30 kW, so which types of property would it be most appropriate for?

An experienced PlumbProud heating engineer would recommend that the most suitable type of property for a Worcester Bosch Greenstar I 30i combi would be medium-sized homes and larger apartments containing 10-15 radiators and providing hot water for two bathrooms.

Flow rates are important when choosing a combi boiler as well as output rates.

A combi boiler's flow rate (measured in litres per minute) describes how much water it can instantly heat then distribute to the taps and radiators in your home - you will need to factor this into your decision on a new combi boiler. This Worcester Bosch Greenstar i 30i Combi boiler's flow rate is 12 L/m.

If you have a lot of radiators and bathrooms in your home and there's lots of demand within your household for hot water at the same time (like morning or evening showers and baths), you'll need a boiler with a high flow rate.

However, it's not quite that simple. If your local mains water pressure is low, you're not going to gain any benefit from choosing a combi boiler with a high flow rate because that higher flow rate doesn't mean it can draw more water from the mains pipes.
When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead if your family's demand for hot water is higher than normal.


What are the proportions of a Worcester Bosch Greenstar I 30i boiler?

The Worcester Bosch Greenstar I 30i is 700 mm tall, 400 mm wide, and 330 mm deep.

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

The Worcester Bosch Greenstar I 30i is a condensing gas boiler - this is the type of boiler we recommend to most clients because they're better for the environment and they will save money on annual fuel bills.

A condensing boiler captures and recycles the warmth still present in both the flue exhaust gases and water vapour condensation created when gas is burned to provide your boiler with power.

This means it needs less gas to operate and it uses this extra energy to perform a number of tasks, including heating the colder water that comes back to the boiler from the radiators in your home.

Is the Worcester Bosch Greenstar I 30i combi good for the environment?

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

We generate 14% of UK greenhouse gas emissions through centrally heating our domestic properties. Gas boilers are mainly responsible for harmful nitrogen dioxide emissions in larger British cities.

Would choosing the Worcester Bosch Greenstar I 30i combi help the environment? Let's see what the statistics suggest.

Boilers manufactured or supplied to UK domestic properties must achieve a legal minimum energy efficiency rating of 92% (equivalent to a good "A" grade using the SEDBUK scale). Prior to this, the minimum was 88% (88% and 89% are a "B" SEDBUK grade and anything 90% or above is an "A" grade).

The energy efficiency rating of a boiler refers to the amount of energy it uses to perform its everyday functions as well as the amount of energy it wastes.

The Worcester Bosch Greenstar I 30i has been given a rating of 90.1% for energy efficiency, equivalent to a SEDBUK "A" rating.

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.

ERP ratings of "A" for heat and "A" for water were assigned when testing the Worcester Bosch Greenstar I 30i.

How long is the warranty period on a Worcester Bosch Greenstar I 30i combi boiler?

The Worcester Bosch Greenstar I 30i boiler is covered by a parts and labour warranty of 7 years.

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

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

You might want to consider the Worcester Bosch Greenstar I 30i for your house or flat if you are looking for a combi boiler.

Traditional boilers consist of one or more large tanks that take up a lot of space in people's homes. One tank heats water and keeps it warm and the other stores water for heating later.

In contrast, a combi boiler is a much smaller stand-alone unit. Instead of requiring water tanks, it draws cold water from the mains. When hot water is needed for a shower, for the washing up, or the dishwasher, the cold water is heated instantly by the boiler and distributed to where it is needed.

The main disadvantage of combi boilers is that there is a limit to how much water they are capable of heating at the same time. For instance, water pressure, volume and temperature will be adversely affected if more than one individual in the home needs hot water at the same time.

Should I install a Worcester Bosch Greenstar I 30i combi boiler in my home?

To determine that, we need to consider the size of the boiler. Size doesn't mean how big it is - it means how big its "output" is.

The output rate of a boiler tells you how much power it has available to it for heating the water that comes out of your taps and warms your radiators. A higher output rate means that your boiler has more power at its disposal.

You need to make sure you select a boiler with the right output rate. That's because, if your output rate is too high, then your boiler will have more power than it needs but it will cost too much to run. If the output rate is too low, your water may often not be hot enough.

The Worcester Bosch Greenstar I 30i combi's output is 30 kW, so which types of property would this Worcester Bosch Greenstar i 30i Combi boiler be appropriate for?

An experienced Gas Safe boiler installer would recommend that the Worcester Bosch Greenstar I 30i combi boiler would be an ideal installation option for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

With all combi boilers, you need to consider the "flow rate" as well as the output rate when making your decision.

Like all combi boilers, the Worcester Bosch Greenstar I 30i draws water from the mains. It instantly heats that water and then distributes it to the parts of your home which need it - taps, radiators, bathrooms, and so on. This Worcester Bosch Greenstar i 30i Combi boiler's flow rate is 12 L/m.

There is no benefit to purchasing a boiler with a high flow rate if the local water pressure is not that good - a high flow rate doesn't mean that your combi can draw more water from the mains.

In addition, if you live in a home with a large number of radiators and more than one bathroom and if more than one person regularly wants to use hot water at a time, a combi boiler may struggle to provide enough water at a hot enough temperature.

When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead if your family's demand for hot water is higher than normal.


Worcester Bosch Greenstar I 30i dimensions

The Worcester Bosch Greenstar I 30i measures 700 mm high and 400 mm wide by a depth of 330 mm.

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

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 I 30i 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.

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

More and more homeowners are aware of the importance of how we heat our homes and its impact on climate change and other environmental issues.

Central heating produces 14% of all greenhouse gas emissions in the UK. Gas boilers in the larger cities emit dangerous levels of nitrogen dioxide.

Would the environmental impact of installing a Worcester Bosch Greenstar I 30i combi in your home be positive? Let's look at the numbers.

Boilers manufactured or supplied to UK domestic properties must achieve a legal minimum energy efficiency rating of 92% (equivalent to a good "A" grade using the SEDBUK scale). Prior to this, the minimum was 88% (88% and 89% are a "B" SEDBUK grade and anything 90% or above is an "A" grade).

The energy efficiency rating of a boiler refers to the amount of energy it uses to perform its everyday functions as well as the amount of energy it wastes.

The Worcester Bosch Greenstar I 30i has been given a rating of 90.1% for energy efficiency, equivalent to a SEDBUK "A" rating.

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 emitted fewer harmful gases with the larger aim of protecting the wider environment.

The Worcester Bosch Greenstar I 30i has been awarded an ERP rating of "A" for heat and "A" for water.

How long is the warranty offered by the manufacturer for the Worcester Bosch Greenstar I 30i boiler?

A parts and labour warranty of 7 years is included with the Worcester Bosch Worcester Bosch Greenstar I 30i boiler.
