Worcester Bosch Greenstar CDi Compact 32 Combi Gas boiler frequently asked questions

Worcester Bosch Greenstar CDi Compact 32 - a regular boiler, combi boiler or system boiler?

When looking for a combi boiler for your house or flat, the Worcester Bosch Greenstar CDi Compact 32 might be a suitable option for you.

Traditional boilers require at least one large cylindrical tank to work, normally housed in a large landing cupboard, utility room or the attic. As the UK has some of the world's smallest residential properties, manufacturers introduced the combi boiler in the 1970s to address the issue of space while meeting homeowners' need for central heating and hot water at the same time.

Combi boilers don't need external storage tanks. Instead, they draw water directly from the mains, heat it and then distribute it on demand to the areas where it is needed.

The most important disadvantage of combi boilers is that they have a maximum capacity for the amount of water they can heat up. This means that, if one person in your household is having a shower and another person turns on a hot water tap elsewhere, then the volume, pressure and temperature of the water to both points decreases.

Is a Worcester Bosch Greenstar CDi Compact 32 combi the right boiler for my house or flat?

Whether this Worcester Bosch Greenstar CDi Compact 32 Combi boiler is right for your property 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 rating indicates how much energy a boiler can use in providing you with hot water and heat when you need it from your radiators and taps. The greater the output, the more water it can heat.

It's better to take advice on this from a registered installer because, if your boiler output is too low, your water and radiators might not get as hot as you would like them to be. However, if the output level is too high, you'll end up paying more on your gas bills than you need to.

Which types of property would this Worcester Bosch Greenstar CDi Compact 32 Combi boiler be appropriate for given its output of 32 kW?

An experienced PlumbProud heating engineer would recommend that the most suitable type of property for a Worcester Bosch Greenstar CDi Compact 32 combi would be medium-sized homes and larger apartments containing 10-15 radiators and providing hot water for two bathrooms.

Please remember too that all combi boilers draw water from the mains - they have no storage tanks. Combis heat the water from the mains on demand and then send it to wherever it's needed in the house, like a radiator, a bathroom or a kitchen.

The speed at which it can do this is called the "flow rate", which is measured in litres per minute. If you have a lot of radiators and bathrooms in your home and multiple people are regularly trying to use the hot water at one time, such as in the morning or evening, you'll need a combi with a high flow rate. This Worcester Bosch Greenstar CDi Compact 32 Combi boiler's flow rate is 13 L/m.

However, it's not that simple. Combis can only draw water from the mains at the speed it's delivered. If the flow rate of the local water supply is 11l/m, you shouldn't purchase a boiler with a flow rate of 17l/m because it will never be able to use that extra capacity.

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.


The dimensions of the Worcester Bosch Greenstar CDi Compact 32 are

Worcester Bosch’s Greenstar CDi Compact 32 is 680 mm tall, 390 mm wide, and 280 mm deep.

Is the Worcester Bosch Greenstar CDi Compact 32 condensing or non-condensing?

The Worcester Bosch Greenstar CDi Compact 32 is a condensing gas boiler - we strongly recommend that you choose one of the latest condensing models if possible.

With a condensing boiler, you save money on your gas bills because your boiler captures and recycles the heat present in the flue exhaust gases and water vapour condensation for re-use, meaning they operate far more economically and efficiently.

How energy efficient is the Worcester Bosch Greenstar CDi Compact 32 combi boiler?

Many homeowners are becoming increasingly concerned about how they heat their homes and the impact it has on climate change and other important environmental issues.

14% of the total amount of greenhouse gases produced by the UK comes from the central heating systems we use. In some of Britain's biggest cities, gas boilers create dangerous levels of nitrogen dioxide in the atmosphere.

Will you be helping the environment if you decide to install a Worcester Bosch Greenstar CDi Compact 32 combi in your home? Let’s look at the figures.

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 CDi Compact 32 was awarded an efficiency rating of 90.5% with a SEDBUK band rating of "A".

Energy-efficient boilers help the environment as they require less fuel and emit fewer harmful gases. In 2015, the EU introduced the Energy Related Products Directive (ERP), the aim of which was to ensure that all manufacturers, including boiler manufacturers, developed more efficient products and processes.

The legislation aims to conserve energy at all life cycle stages from initial production to actual use by the customer, through to the point of disposal.

The Worcester Bosch Greenstar CDi Compact 32 has been given an ERP rating of "A" for heat and "A" for water.

How long is the warranty period on a Worcester Bosch Greenstar CDi Compact 32 combi boiler?

The parts and labour warranty on the Worcester Bosch Greenstar CDi Compact 32 lasts for 7 years.

Worcester Bosch Greenstar CDi Compact 32 Combi Gas boiler frequently asked questions

Is the Worcester Bosch Greenstar CDi Compact 32 a system, regular or combi boiler?

You might want to consider the Worcester Bosch Greenstar CDi Compact 32 for your house or flat if you are looking for a combi boiler.

Traditionally, most boilers required you to find space in your property for one or more large storage tanks. These tanks would either keep water warm or hold it in reserve for later heating. Manufacturers originally introduced combi boilers to offer homeowners the same level of warmth and hot water without taking up as much space – remember that the UK has some of the smallest homes in the Western world.

With a combi boiler, the hot water needed for your radiators and taps is provided on demand. Water from the mains passes through your combi boiler and the technology within it instantly heats the cold water. It then distributes that hot water around your home.

The biggest drawback for combi boilers is that they have a maximum capacity in volume for heating water. This means that if someone wants to use the shower while another person wants to use a hot water tap, the amount of water reaching each point falls, resulting in a drop in water pressure.

Would the Worcester Bosch Greenstar CDi Compact 32 combi boiler be 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.

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 CDi Compact 32 combi's output level is 32 kW, so which types of property would this Worcester Bosch Greenstar CDi Compact 32 Combi boiler be an appropriate choice for?

An experienced PlumbProud Gas Safe boiler installer would recommend that this Worcester Bosch Greenstar CDi Compact 32 Combi boiler is 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 CDi Compact 32, 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 CDi Compact 32 Combi boiler's flow rate is 13 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.


What size is a Worcester Bosch Greenstar CDi Compact 32 boiler?

The Worcester Bosch Greenstar CDi Compact 32 measures 680 mm in height and has a width of 390 mm and a depth of 280 mm.

Is the Worcester Bosch Greenstar CDi Compact 32 a non-condensing or condensing boiler?

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 CDi Compact 32 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 CDi Compact 32 combi boiler 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.

Nitrogen dioxide emissions in Britain's largest cities are at dangerous levels and this has been caused by gas boilers. In fact, 14% of the UK’s greenhouse gases are produced by central heating.

Is the Worcester Bosch Greenstar CDi Compact 32 combi an environmentally friendly choice for your home? Let’s have a look at the figures.

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.

The Worcester Bosch Greenstar CDi Compact 32 was awarded an efficiency rating of 90.5% with a SEDBUK band rating of "A".

The Energy Related Products (ERP) Directive is a European directive which applies to all products that consume energy over their lifetime.

It encourages companies to create products that are environmentally friendlier at all life cycle stages, including initial manufacturing and end use through to final disposal, with the aim of reducing harmful gas emissions.

The Worcester Bosch Greenstar CDi Compact 32 is rated "A" for heat and "A" for water.

Does a Worcester Bosch Greenstar CDi Compact 32 combi boiler come with a warranty period?

The Worcester Bosch Greenstar CDi Compact 32 boiler is provided with a parts and labour warranty lasting 7 years.
