Worcester Bosch Greenstar 2000 30kW Combi Gas boiler frequently asked questions

Worcester Bosch Greenstar 2000 30kW - a combi boiler, system boiler or regular boiler?

The Worcester Bosch Greenstar 2000 30kW is a combi boiler you may wish to consider if you want this particular type of boiler for your house or flat.

Combi boilers are excellent for providing hot water and heat for your radiators just when you need it. When you have a combi boiler installed in your home, you just turn on the tap and the hot water for your bath, shower, washing dishes and other activities is there when you need it. It also provides the heat you need to keep your radiators warm.

A combi boiler heats the cold water passing through it, which it draws from the mains. This newly heated water can then be distributed to whichever hot tap or radiator needs it.

In the past, boilers needed at least one storage tank to hold water that was either already heated or would be heated later. Sometimes, you'd have to wait for hot water because there was none left. In addition, storage tanks took up a lot of space and most UK homes are pretty small.

The main disadvantage to combi boilers is that they can only heat a certain amount of water at any one time, meaning the pressure, volume and temperature of water will decrease if more than one tap is on at the same time or if both the shower and washing machine are on together.

Is the Worcester Bosch Greenstar 2000 30kW combi suitable for my house or flat?

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

Your boiler’s output is a measurement of the power it has available to heat the volume of water required for your taps and radiators. The higher the output rate, the more water it can heat.

You need to be careful to select a boiler with the optimal level of output for your property though. That's because, if your boiler output is too low, your water and radiators will often not be as hot as you want them to be. If the output is too high, you’ll be paying more for gas than you need to.

The output of the Worcester Bosch Greenstar 2000 30kW combi is 30 kW, so which types of property would this Worcester Bosch Greenstar 2000 30kW Combi boiler be appropriate for?

A boiler engineer would be likely to recommend that this Worcester Bosch Greenstar 2000 30kW Combi boiler is capable of providing heating and hot water to 10-15 radiators and two bathrooms and would therefore be most suitable for medium-sized homes and larger apartments.

In addition to the output rate, you should consider a boiler's "flow rate" (measured in litres per minute) when choosing a combi boiler.

If you have a lot of radiators and bathrooms in your home and members of your household want to use hot water at the same time (like morning or evening showers and baths), you'll need a boiler with a high flow rate. This Worcester Bosch Greenstar 2000 30kW Combi boiler's flow rate is 12 L/m.

However, it's not that simple. Combis can only draw water from the mains at the speed it's delivered. Homes with higher than average demand for hot water, and particularly those in low mains pressure areas, may find that a combi boiler is not the right answer for them.

When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead to better serve you and your family.


What size is a Worcester Bosch Greenstar 2000 30kW boiler?

The Worcester Bosch Greenstar 2000 30kW stands at 724 mm tall, 400 mm wide and 300 mm deep.

Is the Worcester Bosch Greenstar 2000 30kW a condensing or non-condensing boiler?

Is choosing the Worcester Bosch Greenstar 2000 30kW combi boiler environmentally friendly?

Many homeowners are now worried about climate change and the damage they do to the environment from heating their homes has become a subject of increasing concern.

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 installing a Worcester Bosch Greenstar 2000 30kW combi boiler in your home be a green choice? 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 2000 30kW has been given a rating of 93% for energy efficiency, equivalent to a SEDBUK "A" rating.

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 2000 30kW is "A" for heat and "A" for hot water.

How many years does the warranty period cover on a Worcester Bosch Greenstar 2000 30kW boiler?

Worcester Bosch Greenstar 2000 30kW Combi Gas boiler frequently asked questions

Is this Worcester Bosch Greenstar 2000 30kW boiler a combi, system or regular boiler?

If you want a combi boiler for your flat or house, the Worcester Bosch Greenstar 2000 30kW might be an option for you to consider.

Combi boilers were introduced by manufacturers in the 1970s to offer British homeowners a way to cheaply and reliably heat their homes and have hot water without taking up too much space. Previously, most boilers had one or more storage tanks, which either heated water and kept it warm or held water to be heated later.

With combi boilers, there is no need to find space for large tanks around your home as the hot water needed for your radiators and taps is available on demand. Combi boilers do this by drawing water from your mains supply, heating it instantly whenever you need it and then distributing it to where it's needed in the home.

The major disadvantage to combi boilers is that they have a maximum capacity for heating water. In a larger household, water pressure, volume and temperature will drop if two or more people are trying to use hot water at the same time.

Is a Worcester Bosch Greenstar 2000 30kW combi boiler suitable for my house or apartment?

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 2000 30kW combi's output at 30 kW, which types of property would this Worcester Bosch Greenstar 2000 30kW Combi boiler be most appropriate for?

Most experienced boiler engineers would recommend that this Worcester Bosch Greenstar 2000 30kW Combi boiler would be suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

When choosing a combi boiler like the Worcester Bosch Greenstar 2000 30kW, you need to consider the "flow rate" as well as the output rate. Flow rates (measured in litres per minute) indicate the volume of hot water that the boiler can heat up and then distribute to your taps and radiators.

However, combi boilers draw water from the mains and this means they can only heat the amount of water that actually enters your property.

What this means is that, if your mains pressure is 12 litres per minute, that is your boiler's effective flow rate even if it has the capacity to process 18 litres per minute. This Worcester Bosch Greenstar 2000 30kW Combi boiler's flow rate is 12 L/m.

To give you an idea of the flow rate you might need, a power shower typically requires around 12 litres of water per minute and a basin tap requires 4-8 litres per minute.

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 2000 30kW dimensions

The Worcester Bosch Greenstar 2000 30kW is 724 mm tall, 400 mm wide, and 300 mm deep in size.

Is the Worcester Bosch Greenstar 2000 30kW condensing or non-condensing?

How energy efficient is the Worcester Bosch Greenstar 2000 30kW combi boiler?

Environmentally-friendly heating has become an important issue for homeowners concerned about the accelerating pace of climate change.

About 14% of the greenhouse gases we produce in the UK come from the power needed for central heating. In bigger British cities, gas boilers are a significant source of nitrogen dioxide emissions.

Would choosing the Worcester Bosch Greenstar 2000 30kW combi help the environment? Let's see what the statistics suggest.

Boilers manufactured and installed in the UK are assigned energy efficiency ratings following testing to an agreed set of standards. These scores indicate how much energy the boiler uses and how much goes to waste when it's in operation.

By law, boilers must achieve a SEDBUK rating of "A" subject to achieving a minimum of 92% energy efficiency. Prior to April 2018, the minimum was 88% (88% and 89% on the SEDBUK are graded "B" and 90% and above is graded "A").

The Worcester Bosch Greenstar 2000 30kW was awarded an efficiency rating of 93% with a SEDBUK band rating of "A".

The Energy Related Products Directive, also known as ERP, is European legislation that intends to reduce energy consumption related to products right from the initial manufacturing process through to eventual final disposal.

The purpose of the directive is to encourage manufacturers to create new products that are kinder to the environment and which result in lower overall harmful gas emissions through a product's entire life cycle.

The Worcester Bosch Greenstar 2000 30kW has a rating of "A" for heat and "A" for water.

How many years does the warranty period cover on a Worcester Bosch Greenstar 2000 30kW boiler?

On the Worcester Bosch Greenstar 2000 30kW, the manufacturer offers a parts and labour warranty of 5 years.
