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

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

The Worcester Bosch Greenstar CDi Compact 32 boiler is a combi boiler you may wish to consider when looking for a new boiler for your house or flat.

Traditional boilers have one or two tanks - one holds hot water to keep it warm and the other water for later heating. Because UK residential property is among some of the smallest in the world, manufacturers introduced combi boilers and the heat pumps that go in them in the 1970s to reduce the amount of space boilers needed to take up.

The hot water needed for your radiators and taps is available on demand when you have a combi boiler. Combi boilers use technology located within the boiler to heat cold water, which it draws from the mains, and to distribute hot water where it's needed around your home.

A combi boiler, however, has the disadvantage of a maximum capacity for the amount of water it can heat. The result is that if someone uses the shower while another uses a hot water tap simultaneously, the amount of water reaching each point falls, causing water pressure to drop.

Should I install a Worcester Bosch Greenstar CDi Compact 32 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.

Your boiler's output indicates the maximum amount of power available to it to heat the water you need to warm your radiators or when you want hot water from your taps. A higher output rate means that your boiler is capable of heating greater volumes of water.

If a boiler's output rate is too low, you'll often find that the water is not as hot as you want it to be. Too high, however, and you'll end up paying more for your gas than you should be.

The Worcester Bosch Greenstar CDi Compact 32 combi boiler has an output rate of 32 kW, so which types of property would this be suitable for?

An experienced Gas Safe boiler installer would recommend that the Worcester Bosch Greenstar CDi Compact 32 combi boiler would be an ideal installation option for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

The Worcester Bosch Greenstar CDi Compact 32 is a combi boiler, which that means that you need to take the flow rate (measured in litres per minute) into account as well as the output rate. This Worcester Bosch Greenstar CDi Compact 32 Combi boiler's flow rate is 13 L/m.

Combis draw water from the mains, instantly heating and distributing it where it's needed - taps, radiators, bathrooms, and so on.

However, this means that the flow rate of a boiler may effectively be capped by the flow rate of the mains water supply. For example, if your mains pressure is 12l/m, that is the maximum flow rate that your boiler can achieve even if you choose a boiler with a flow rate of 18l/m.

In addition, if your home has more than one bathroom, a high number of radiators, and more than one member of your household wants to use hot water at the same time regularly, the flow rate of both the boiler and the mains water pressure may not be high enough.

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.


Dimensions of the Worcester Bosch Greenstar CDi Compact 32 boiler

The Worcester Bosch Greenstar CDi Compact 32 is 680 mm in height, 390 mm in width and 280 mm in depth.

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

The Worcester Bosch Greenstar CDi Compact 32 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 CDi Compact 32 combi 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.

The heating of our homes accounts for 14% of the UK's greenhouse gas emissions. Especially in the big cities, gas boilers are responsible for dangerous levels of nitrogen dioxide emissions.

Will installing a Worcester Bosch Greenstar CDi Compact 32 combi in your home be a positive contribution to the environment? The figures below will tell you more.

All boilers manufactured in the UK from April 2018 must operate at a minimum level of energy efficiency of 92% ("A" rating on the SEDBUK scale). Before that, the minimum was 88% - boilers scoring 88/89% were given a SEDBUK "B" rating and 90% or above an "A" rating.

The energy efficiency score of a boiler indicates how much energy it uses and how much goes to waste when in use.

After its assessment, the Worcester Bosch Greenstar CDi Compact 32 was given an efficiency rating of 90.5% and a SEDBUK grading of "A".

The Energy Related Products Directive (ERP) is European legislation that applies to all products which use or consume energy during their lifespan, including during the manufacturing process and when they're in actual use, right through to the point of final disposal.

The aim is to encourage manufacturers to create new products that are kinder to the environment and create fewer harmful gas emissions.

The Worcester Bosch Greenstar CDi Compact 32 has an ERP Heat rating of "A" and an ERP Water rating of "A".

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

Is the Worcester Bosch Greenstar CDi Compact 32 a regular, combi 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 have one or two tanks - one holds hot water to keep it warm and the other water for later heating. Because UK residential property is among some of the smallest in the world, manufacturers introduced combi boilers and the heat pumps that go in them in the 1970s to reduce the amount of space boilers needed to take up.

The hot water needed for your radiators and taps is available on demand when you have a combi boiler. Combi boilers use technology located within the boiler to heat cold water, which it draws from the mains, and to distribute hot water where it's needed around your home.

A combi boiler, however, has the disadvantage of a maximum capacity for the amount of water it can heat. The result is that if someone uses the shower while another uses a hot water tap simultaneously, the amount of water reaching each point falls, causing water pressure to drop.

Should I install a Worcester Bosch Greenstar CDi Compact 32 combi boiler in my home?

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

This Worcester Bosch Greenstar CDi Compact 32 Combi boiler gets its power from gas and the power it's capable of producing is measured in kilowatts - the output rate is actually a kilowatt rate. The higher the output rate, the more kilowatts a boiler can use when heating water.

If you choose a boiler whose output rate is too low, it may not have enough power to make your water as hot as you would like. If you choose a boiler whose output rate is too high, you won't have to put up with lukewarm water but you will face higher gas bills.

The Worcester Bosch Greenstar CDi Compact 32 combi boiler has an output level of 32 kW, so which types of property would it be 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.

You should also consider a combi boiler's "flow rate" when making your choice.

The flow rate indicates how much water it can take from the mains supply at any one time (measured in litres per minute), which it then heats and distributes to different points in your home like your bathroom, kitchen and radiators. This Worcester Bosch Greenstar CDi Compact 32 Combi boiler's flow rate is 13 L/m.

Combi boilers have no storage tanks like system or heat only boilers. This means that if the water pressure where you live is low, there's no benefit in spending money on a combi with a high flow rate because a high flow rate doesn't mean it can draw any more water from the mains.

In addition, there might be lots of people in your household who want to use hot water at the same time while also having the central heating on. Given that average mains pressure in the UK is between 10 and 12 litres per second and a power shower usually requires about 12 litres of water per minute, a combi boiler might not be the right choice for you and your family.

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.


How large is the Worcester Bosch Greenstar CDi Compact 32?

The dimensions of the Worcester Bosch Greenstar CDi Compact 32 are 680 mm tall, 390 mm wide, and 280 mm deep.

Is the Worcester Bosch Greenstar CDi Compact 32 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 CDi Compact 32.

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.

What energy efficiency ratings have been awarded to the Worcester Bosch Greenstar CDi Compact 32 combi?

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

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.

Would choosing the Worcester Bosch Greenstar CDi Compact 32 combi be an environmentally-friendly choice? If so, let's look at its performance figures.

All boilers manufactured and supplied in the UK must achieve an energy efficiency rating of at least 92% (an "A" SEDBUK grade). This is higher than the previous 88%, which was a legal requirement prior to April 2018.

The energy efficiency rating is used to work out how much energy a boiler both uses and wastes when it's switched on and working correctly - its standard functioning and operation.

The Worcester Bosch Greenstar CDi Compact 32 is rated as 90.5% energy efficient, equivalent to a "A" SEDBUK rating.

The aim of the Energy Related Products (ERP) Directive is to reduce the harmful gas emissions created during a product’s manufacture and active end use right through to its disposal.

The ERP rating for the Worcester Bosch Greenstar CDi Compact 32 is "A" for heat and "A" for water.

Is there a warranty on the Worcester Bosch Greenstar CDi Compact 32 combi boiler if it breaks down?

The Worcester Bosch Greenstar CDi Compact 32 boiler offers a parts and labour warranty of 7 years.
