†Terms and conditions apply. * The friction stir welding process is used under license from The Welding Institute.

Innovation at its best – the new WB7 heat exchanger

Aeroplane wings, cryogenic fuel tanks, military and scientific rockets.

Marine panels for decks, hulls and helicopter landing platforms.

Wheel rims and motor cycle frames. High speed trains and underground carriages.

What is friction stir welding?

• Friction stir welding is a solid-state joining process where metal is not

melted, but softened. In this process no additional material is added

to form a joint. Instead, the two plates are stirred together forming a

weld line, which gives improved quality, reliability and performance

to the component.

• The frictional heat is generated along the weld line by a rotating

welding tool.

• The heat generated by the mechanical mixing process causes the

stirred metals to soften, allowing for an easy navigation along the

weld lines that, in its crystallized state, forms the weld.

Why use friction stir welding?

• Friction stir welding provides the ability to manufacture a compact

designed heat exchanger which, in turn, reduces the size of the boiler,

giving greater flexibility to both the installer and homeowner.

• It improves reliability as the welding method eliminates the risk

of potential weak points and stress fractures occurring.

• It is also environmentally-friendly, reducing the amount of

raw materials used.

How is the WB7 heat exchanger manufactured?

• The casting process begins with the joining together of four aluminium

panels, under high pressure, using friction stir welding technology.

• This is followed by a four-sided machining process, ensuring optimum

production efficiency.

• The machined heat exchanger is then assembled and 100% tested

before being transformed into a WB7 heat exchanger.

You can view a video of the friction stir welding process by visiting www.worcester-bosch.co.uk/stir-welding-video

The WB7 heat exchanger fitted within the CDi Compact has been

purpose-designed and manufactured by Bosch Thermotechnology Ltd.

By utilising an innovative friction stir welding process*, improved

reliability, efficiency and domestic hot water flow rates of up to

14.7l/min can be achieved.

This unique friction stir welding process provides the heat exchanger

with added strength and durability due to this stronger welding method.

For the homeowner this provides greater peace of mind, which is further

strengthened by a 10 year guarantee on the WB7 heat exchanger.†

Worcester is the first UK heating manufacturer to use friction stir welding for continuous large quantity production. A signal of our commitment to continue to be the class leader in quality, reliability and innovation.

Easy-to-use, cutting edge in-built displayThe Greenstar CDi Compact has a new in-built boiler display, to give both the installer and

homeowner a vast range of features that allow the heating system to be as efficient and

flexible as possible.

Easy to read and monitor – The large screen means system parameters such as hot

water flow rate and heating flow and return temperature can be easily set up by the installer

during commissioning.

Maximum set temperature – While it is easy to observe and adjust the temperature to suit

individual requirements, the screen menu also allows the ability to set a maximum temperature

for the boiler. Once set, the maximum temperature cannot be overridden no matter how much

the dial is turned – improving the overall efficiency of the boiler.

Testing mode – The simple-to-use engineers menu can automatically check the operations of

various boiler components, without the need to remove the boiler front cover. Any problems can

be easily recognised with diagnostic codes narrowing the potential causes of the problem.

Combi pre-heat mode – With the domestic hot water combi pre-heat accessory fitted,

the CDi Compact can accept pre-heated water up to 60°C from a secondary source such

as Greenskies solar thermal.

ECO mode – When set to ECO mode, the CDi Compact will use less gas or LPG, as the energy

will only be used on demand, allowing for energy-saving fuel consumption.

Comfort mode – All Greenstar combi boilers have an in-built ‘keep hot’ or ‘pre-heat’ facility

which will keep the primary water within the heat cell hot. This ensures that hot water is

delivered instantaneously to an opened outlet.

Optional plug-in controls – With front access easy wiring, the Greenstar CDi Compact is

also compatible with all Worcester on/off and intelligent controls options. Third party heating

controls may also be used.

Our Greenstar boilers are subjected to 20,000 electromagnetic surges at up to 3,000 volts to ensure they can perform in the event of exceptional power surges.

The Worcester control series

As part of the Bosch Group, Worcester is committed to new product development, economical use of heating

systems and environmental protection. As part of this commitment Worcester has a range of intelligent heating

controls designed to enhance the integral efficiency of our Greenstar CDi Combi range.

Why invest in intelligent controls?More efficient heating system – The operating efficiency of a condensing boiler can be increased when

combined with the correct controls*.

Regulations and best practice – In addition to the end users’ requirements, there are also current and future

regulatory influences on the control of heating.

For new and replacement boiler installations you must have either: a timer or programmer with a room thermostat

and thermostatic radiator valves or a programmable room thermostat and thermostatic radiator valves.

What heating and hot water control options does Worcester offer?Mechanical timers – Simple to operate and offer the minimum features needed, these include our MT10

and MT10RF controllers. Basic mechanical timers control the times for your heating only. The ‘teeth’ on the

mechanical dial are used to control 15 minute periods and the heating pattern set will be the same every day.

Digital timers and programmers – Worcester DT10RF, TD200 text display and RT10 room thermostat offer

greater flexibility in controlling heating and hot water. Digital timers, programmers and programmable room

thermostats provide more options. As a general rule, the controls can program different patterns for different

days of the week which can be particularly useful for weekends.

Intelligent controls – Achieve the greatest efficiency from the boiler. These include the FR10 Intelligent Room

Thermostat, FR110 Programmable Room Thermostat, ISM1 Intelligent Solar Module and FW100 Weather

Compensation Controller. The latest range of boiler controls from Worcester not only responds to the users’

settings but also assesses and adjusts the boiler’s output to make it more energy efficient.

*Depending on boiler size and heating load.

The Worcester range of controls includes simple-to-use mechanical timers to advanced intelligent controls.

Worcester intelligent controls.


Worcester’s innovative heating and hot water

product range is designed for the needs of

today’s home. In addition to combi boilers,

the Greenstar gas-fired range also features

Regular and System models.

Greenstar oil-fired condensing boilersWorcester also manufactures a range of high-

efficiency oil-fired Greenstar boilers. Our oil

manufacturing heritage stretches back to the

foundation of the company in 1962 and like all

our Greenstar gas combi boilers, our range

of oil-fired boilers is recommended by the

Energy Saving Trust, and runs at 90% efficiency

(SEDBUK 2005 rating) or over.

Greenskies solar thermal water heatingWorcester’s Greenskies solar thermal evacuated

tubes and flat plate panels are capable of providing

up to 60%* of a home’s hot water requirements. The

panels are designed to link into any existing heating

system that uses a cylinder, using even diffused

sunlight to covert energy into heat and produce hot

water for the home.

Greenstore ground source heat pumpsGreenstore ground source heat pumps harness the

energy stored in the earth to provide heating and

hot water for the home. For every single kilowatt of

electricity used to power the ground source heat

pump, the system can generate four kilowatts of

energy for the home. Not only that, but the system is

designed to be the sole heating source in the home.

Greensource air source heat pumpsGreensource air source heat pumps gather energy

from the air and transfer it into low cost heating

and hot water for the home. Worcester’s range of

air source heat pumps can offer a choice of three

systems: air to air, air to water and split air to water,

each offering significant savings compared with a

conventional heating system.

Greenfloor heatingGreenfloor heating is designed to deliver highly

efficient heating, as well as being an ideal partner

to heat pumps and condensing boilers. Underfloor

heating is suitable for refurbishments and new build

properties and distributes heat evenly for optimum

user comfort.

Even more ways of providing heating and hot water comfort

Worcester has always placed great emphasis on technical support and training for professional installers and

service engineers. For more than 25 years, Worcester has offered first-class training in the UK. On average

Worcester train over 15,000 installers every year providing industry recognised training across four Training

Academies and over 150 colleges to ensure they receive the highest levels of expertise in the installation of

all Worcester products.

Why invest in training?Changing and updating technology – Over recent years, the face of the heating industry has changed

dramatically, with new technologies emerging alongside the more mainstream options. Hands-on training

with new technologies is a sure-fire way to keep up to speed with industry developments.

Keep up to date with legislation – With new technologies come new rules and regulations. Investing time

in legislative knowledge is as important as understanding the products themselves.

Diversify and expand your business – The diversity of products in today’s heating industry gives

you the opportunity to expand your expertise, whilst offering more choice to your customers.

Improving installation standards – Worcester understands that ‘Best Practice’ is what all installers

strive for. With the industry and its standards constantly evolving, attending training courses can help

keep you up-to-date with the latest requirements.

If you can’t get to a Worcester training course, we will come to you. Our mobile trainers run approximately 800 courses per year from the very north of Scotland to the southern tip of Cornwall and even the Isle of Man.

and this is demonstrated no more than in the commitment we have to being an

environmentally responsible manufacturer.

From detailed environmental policies, our Environment 2020 awards, Energy Homes

across the country and creating a children’s book aimed at educating future generations,

we are continually looking for new ways to minimise our impact on the planet.

Setting new standards for the industry, Worcester implemented a new business system

As committed to our social responsibilities as we are to our customers

Volunteering 50 work days to local charitiesIn addition to the dedication and care we take towards the

environment, Worcester also has a close relationship with local

charities around the Worcestershire and Derbyshire regions.

Worcester staff took time out of their normal jobs to do a variety

of tasks such as painting the facilities of Sight Concern or Acorns

Children’s Hospice, helping to build local wildlife areas and even

de-rusting and repainting at the Severn Valley Railway.
