Innovation at its best – the new WB7 heat exchanger The WB7 heat exchanger fitted in the CDi Compact has been purposedesigned and manufactured by Bosch Thermotechnology Ltd. using an innovative friction stir welding process.* This is to provide improved reliability, efficiency and domestic hot water flow rates of up to 14.7l/min, while also giving a greater surface area and improved efficiency for an optimum heat exchange between the gas and water channels.

Giving greater reliability and homeowner peace of mind, this unique friction stir welding process provides the heat exchanger with added strength and durability through its stronger welding method. This peace of mind is further strengthened with a 10 year guarantee on the heat exchanger.†

What is friction stir welding?

Friction stir welding is a solid-state joining process where metal is not melted, but softened. No additional material is added to form a joint, rather the two plates are stirred together forming a weld line, this 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 factures occurring.

• It is also environmentally-friendly, reducing the amount of raw materials used.

How is the WB7 heat exchanger manufactured?

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

Marine panels for decks, hulls and helicopter landing platforms.

• 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.

Wheel rims and motor cycle frames.

High speed trains and underground carriages.

The Worcester Greenstar CDi Combi set the benchmark within the industry when it was launched with its innovative range-adaptable WB5 heat exchanger.

The aluminium-silicon heat exchanger, with its extra surface area, allows for flue gases which would normally be lost to the atmosphere to instead be released and applied to the system.

Its ability to extract as much heat as possible from the gas it burns gives the Greenstar CDi Classic condensing combi range an exceptionally high level of efficiency while achieving a market-leading 42kW output.

The advanced heat exchanger means the Greenstar CDi Classic can produce hot water to multiple taps at one time, while supplying enough power to cater for multiple radiators. The Greenstar CDi Classic is range-adaptable, meaning its central heating output can be tailored to a range of properties.

The boiler has an annual efficiency of over 90%†, and because it condenses in both heating and hot water modes, it can efficiently produce heating and hot water for the home. Worcester’s commitment to reduce emissions from gas-fired condensing boilers sees the CDi Classic achieve three credits under the Code for Sustainable Homes, allowing it to be ‘new build ready’.

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 by as much as 13% when used with 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.

Even more ways of providing heating and hot water comfort 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 boilers Worcester 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 heating Worcester’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 pumps Greenstore 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 pumps Greensource 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 heating Greenfloor 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.
